Google Pixelbook Go review: Function over form - Engadget

Sponsored Links

Google has been building its own Chromebooks for a while now -- first, there were two iterations of the Chromebook Pixel, and then there was 2017's Pixelbook. All three were great laptops with one glaring flaw: They cost way too much money. We're talking $1,000 or more, at a time when most Chromebooks were $500 or less. Google is back at it this year with the new Pixelbook Go -- but for the first time, the company is no longer aiming for absolute quality regardless of price, just to prove a point.

Instead, Google is trying to build a Chromebook that anyone can use and afford: The Pixelbook Go starts at $649, a full $350 less than the original Pixelbook. It's still a lot of money for a Chromebook. But there are plenty of other manufacturers building premium Chromebooks in that price range now. The Pixelbook Go certainly can hold its own against just about any other Chromebook out there. But unfortunately, in its quest to get the price down, Google also sacrificed a lot of what made the original Pixelbook so intriguing in the first place. The question is whether those trade-offs are worth it.

Summary

Google’s most affordable Chromebook yet is a solid all-around laptop. It’s not as eye-catching as the original Pixelbook, and Google cut a few corners to get the price down (most notably the display).. But the Pixelbook Go covers the basics well and should serve most people well.

Hardware

All of Google's previous Chrome OS devices, had premium hardware and specs, with very few corners cut. With the Pixelbook Go, Google is changing the formula slightly. It's a solid, well-made device that doesn't feel cheap, something we can't say about other Chromebooks. But visually, it's far less interesting than the model it replaces.

The Go is a basic-looking clamshell laptop with a 13.3-inch, 1080p touchscreen and a black paint job, nondescript except for a small 'G' logo in the corner of the lid. It also comes in a light pink shade with a bright coral underside -- a more distinctive combo, though the all-black design is undoubtedly more elegant. (Fans of the black MacBook from the last decade should be pleased.) Regardless of color, the Go is sturdy and well-built but doesn't have any of the distinctive design elements you'll find on the original Pixelbook. It's thicker than that device, though it weighs about the same at 2.3 pounds. I definitely miss the aesthetics of the original, particularly its glass-and-aluminum lid that echoed the design of Google's Pixel phones. The Go has a functional, utilitarian design, which I can appreciate, but I wish it were slightly more exciting.

There is one new, funky design flourish to be found on the Pixelbook Go: its ridged underside. When I first saw pictures of the Go, my brain assumed those ridges were a a different, softer material than the magnesium that makes up the rest of the Go. I was imagining the whole bottom being a grippy plastic like the feet underneath most laptops. But in reality, it's the same hard metal. Google says it designed these ridges to make the laptop easier to grip or pull out of a sleeve, but I can't say this really solves a problem I had with other devices. Still, it's good to see Google show its playful side on this otherwise dull laptop.

Google surely simplified its design as a way to cut costs, and as such, there are some other notable omissions this time around Unlike the first Pixelbook, it's not a convertible, so tablet mode is out. That also means it doesn't work with the Pixelbook Pen stylus. I can't say I really miss these changes, though -- I've never been a fan of laptops that also try and be tablets, and the Pixelbook Pen wasn't terribly useful either.

More concerning to me is the step backward Google took with the Go's display. Both the Pixelbook and last year's ill-fated Pixel Slate had some of the best screens you could find. I particularly liked the original Pixelbook's taller aspect ratio, and both devices had higher resolutions than the Go's 1080p panel.

That's not to say the Go has a bad screen, but it is fairly pedestrian. 1080p on a 13.3-inch display works out to 166 pixels per inch, a far cry from the 235 ppi on the first Pixelbook and the impressive 293 ppi on the Pixel Slate. Google does offer the Go with a 4K screen, but that option is only available if you get the top-of-the-line model, which costs an eye-popping $1,399. The good news is that the Go has much slimmer bezels than the original Pixelbook, but I still prefer the taller and more pixel-dense display on that laptop to the Go's screen.

Google Pixelbook Go

While the screen is a bit of a letdown, Google didn't skimp on the keyboard. The original Pixelbook offered a great typing experience, and the Go is nearly as good. It's hard to describe exactly what's different, but the keys don't feel quite as soft when you're typing. That said, there's plenty of travel and they're quiet as well -- if you hate the low-travel MacBook keyboard, you'll love the one on the Go. The trackpad, on the other hand is... just fine. It feels kind of rough under my finger, and scrolling around isn't as smooth as I'd like. It's not bad, and I got used to it, but I've definitely used better touchpads.

In use

While Google cut some corners in the design department, the Pixelbook Go is still among the more powerful Chromebooks out there. The base model pairs an eighth-generation Intel Core m3 processor with 8GB of RAM and 64GB of storage; the one I reviewed steps up to an i5 processor and 128GB of storage. That model costs $849 and has comparable specs to what you'll find in the $999 Pixelbook. I do wish I could have tried the m3 model, because I'm curious to see what kind of performance Google is offering for $650.

Unsurprisingly, Intel's Core i5 and 8GB of RAM is plenty for Chrome OS. The Pixelbook Go handled my normal workload without any notable issues. My routine involves a dozen or so browser tabs, Tweetdeck, Hangouts, Slack, Todoist, Google Keep and Trello all running as Chrome apps, along with the occasional Android app or two. Adobe's Lightroom, Netflix, YouTube Music and a smattering of games all mostly worked well, though music playback presented the occasionally "low memory" hiccup which was frustrating. Notably, this didn't happen when using YouTube Music as a browser tab. This reinforces my belief that Android apps on Chrome aren't worth using if there's a web-based alternative.

Google Pixelbook Go

Overall, I think most people will be fine with the base configuration; power users may want to step up to the $849 model I tried. Google is also selling a $999 configuration that doubles the RAM to 16GB, while that $1,399 model I mentioned includes a Core i7 processor, 16GB of RAM, 256GB storage and a 4K display. While I'd surely enjoy that high-res screen, I don't think it's worth that kind of money.

The Pixelbook Go also holds up well on the battery side, something that wasn't always true for the original. In our video playback test, the Go ran for just over 13 and a half hours before shutting down. That's more than an hour longer than the 12-hour battery life Google claims with "mixed usage." Unfortunately, I never came close to 12 hours when putting the Go through my normal routine, but it did last more than eight hours, which is a definite improvement over the first Pixelbook.

I will note that my review Pixelbook had a weird issue where the battery life indicator didn't update properly. It showed whatever percentage it was app when it was awoken from sleep and didn't update until it went to sleep again or was plugged in. Google confirmed it was a bug with the current version of Chrome OS that would be updated by the time the device shipped. The company also confirmed that the battery was otherwise performing normally and that this was just a software issue. I'll check this again once the software update arrives and will update this review if the problem persists.

The competition

There are tons of Chromebooks you can compare the Go to, from cheap $200 devices (with specs to match), up to Google's own Pixelbook from 2017 that still sells for $1,000 or more. That said, probably the closest comparison to the Pixelbook Go is the ASUS Chromebook Flip C434, which I reviewed earlier this year. It has an m3 processor, 1080p screen, 4GB of RAM and 64GB of storage, just like the base Pixelbook Go. At $579, it's cheaper than the Go, but also thicker and heavier. It does have a 360-degree hinge, but I never wanted to use the Flip in tablet mode, since it weighs more than three pounds.

Acer has its own high-end option, the Chromebook 13 CB713. For $800, you get an eighth-generation Core i5 processor, a higher-resolution screen (2,256 x 1,504), 8GB of RAM and 64GB of storage. Like the Chromebook Flip, though, it's larger and heavier than the Go.

Google Pixelbook

And then there's the original Pixelbook, which still starts at $999. That's $150 more than the Go model I tested, but it has the same RAM and storage as well as an i5 processor (it's a seventh-generation chip, though, compared to the eighth-gen one in the Go). The extra cash gets you a thinner, more compact design with a better trackpad and much sharper display. It also supports the Pixelbook Pen and has that nifty 360-degree hinge. There are some definite benefits to the original Pixelbook -- and it has been heavily discounted over the last year, sometimes down to $750. If you can wait, it might be worth seeing if it gets any further price cuts this holiday season.

Wrap-up

Nathan Ingraham / Engadget

The Pixelbook Go is much easier to evaluate than either the first Pixelbook or the Pixel Slate. It's a standard, familiar, almost boring laptop. But instead of figuring out if Chrome OS works on a convertible tablet or if you're willing to spend $1,000 on a premium laptop, the Go is just a straightforward, no-frills device. It's still not cheap, particularly if you step up to the i5 processor I tried. But premium Chromebooks in the $600 to $800 range are becoming more common, and now Google has something that can compete on price as well as quality.

Yes, you can still get a Chromebook for less money than what Google is asking. But if you think a Chromebook can be your main computer and don't mind paying a little extra for a device that's thin, light and well-engineered, the Pixelbook Go will likely meet your needs.

Google Pixelbook Go review: A more affordable alternative to the original Pixelbook - Ars Technica

Pixelbook Go review: A cheaper Pixelbook does not come without compromises
Valentina Palladino

Google's relationship with its own Chrome OS hardware has been a peculiar one. While other OEMs regularly push out new Chromebooks for users with various budgets, Google continues to refresh its hardware just once a year. Until now, those updates have produced luxury Chromebooks with varying degrees of popularity: 2017's Pixelbook won many hearts with its unique design, versatility as a convertible, and solid performance, while 2018's Pixel Slate tablet was a decided flop.

For 2019, Google is again trying something a little different: the $649 Pixelbook Go, a more modest Chromebook with a starting price that many will find easier to stomach than the Pixelbook's $999 price tag. While the Pixelbook Go may not be a luxury device, it's not a dirt-cheap Chromebook either. It sits in a category of higher-end Chromebooks that's getting more populated as companies including Acer, Asus, HP, and others make more capable devices.

The biggest draw of the Pixelbook Go is that it's made by Google, and since we saw the company bring so much to the table with the Pixelbook, it's fair to assume that the Pixelbook Go would offer something inherently Google-y that other OEMs can't match. The company is hoping that X factor (along with a more affordable starting price) will bring Chrome OS lovers flocking to the Pixelbook Go. But after using the Pixelbook Go for almost a week, I found that, like most things in the consumer tech world, the reality is not that simple.

Google Pixelbook Go

(Ars Technica may earn compensation for sales from links on this post through affiliate programs.)

At launch, it was easy to compare the Pixelbook Go to a MacBook in style, but Google's new laptop feels noticeably different from Apple's signature laptop. Both are minimalist in their own way, and they share a scarcity of ports—the Pixelbook Go only has two USB-C ports (both of which support charging, data transfer, and display output) and one 3.5mm headphone jack.

But the similarities stop there. Magnesium makes up most of the Pixelbook Go's chassis, giving it a pleasant yet strange feeling in your hands. It doesn't quite feel like metal, but it also doesn't quite feel like a plastic laptop. It lies somewhere in-between, but thankfully that limbo doesn't make it feel cheap. On the contrary, the Pixelbook Go has a build quality that I'd expect in a mid- to high-end laptop. The lid had a slight bit of flex, but the chassis itself doesn't flex at all, and the unique texture of its ribbed bottom keeps the device in place on a flat surface without being distracting.

Google outfitted the Pixelbook Go with a 13.3-inch 1920 x 1080p touchscreen that seems just fine for a Chromebook like this at first blush. However, a few things could be improved or changed based on our usage—first and foremost being the incessant glare that appears when any amount of sunlight falls on the display. It was frustrating to work on the Pixelbook Go in my home office in the same position I test other laptops because that spot gets so much natural light. Also, the display has chunky bezels hugging its top and bottom that I wish had been shrunk—doing so may have allowed a 16:10 or a 3:2 panel rather than the cramped 16:9 panel we got on the Pixelbook Go.

The display also didn't need to be a touchscreen because the Pixelbook Go is a laptop, not a convertible like the Pixelbook. Admittedly, some users may find it easier to navigate Android apps on a Chromebook using their fingers, just like they would on an Android smartphone. However, touchscreens just aren't as comfortable to use on laptops as they are on convertibles and I generally find no use for them on the former devices. It's also disappointing, and slightly confusing, that the Pixelbook Go's screen can take input from your finger but not from a stylus like the Pixelbook Pen.

The top-tier configuration of the Pixelbook Go is the only one to have a 4K panel, and that's not the only perk that increases the value of the $1,399 model. The specs on that model are also better: Core i7 processor, 16GB of RAM, and 256GB of storage—arguably more power than anyone needs in a Chromebook. Nevertheless, aside from the 4K display and internal specs, the top-tier model is identical to all the other Pixelbook Go models in hardware design.

Keyboard, trackpad, and features forgotten

We'll get into the consequences of that fact after we discuss the keyboard and trackpad. The keyboard has a standard Chrome OS layout—the Launch key replaces the Caps Lock key and the top-right Delete key is slightly smaller than I would like. The page navigation keys are also slightly narrower than normal, but they won't impact most users too much.

Google claims the new, backlit keyboard on the Pixelbook Go is quieter than that on the Pixelbook, and that's true to a degree. The keycaps have a softer sound when you click them, so you don't get any satisfying click noises out of them. But the Pixelbook's keyboard wasn't all that loud to begin with, so I see this as a minor improvement rather than something that will have a massive impact on the number of people buying a Pixelbook Go.

It seems Google tried to translate the Pixelbook's uniquely Google-y design for a more affordable device, and I think the company did so to a certain extent. The Pixelbook Go has the same aesthetic as the Pixel 4, which, depending on your personal preference, could be a great thing. If you like thin-and-light laptops with few frills, the Pixelbook Go will be right up your alley.

It also makes for a solid mid-range device, but its validity as a high-end device is debatable. I'm disappointed that the top-tier configuration only adds better specs and a 4K display. I wish Google gave users more for their money and included more hardware differences like pen support or a fingerprint sensor (remember the Pixel Slate had one?) in the $1,399 model. Plenty of Windows laptops in the $799 to $999 range include such features—and even some competing Chromebooks in that price range include them as well.

Google's rationale for this is that it wanted to make the Pixelbook Go more affordable in every way possible—not only for consumers to buy, but for Google to make. Doing so meant stripping out any features that Google felt were unnecessary to on-the-go use and refactoring features of the Pixelbook that were fan favorites, such as the keyboard. We could debate the usefulness of certain features on an ultraportable until we're blue in the face, but it doesn't bode well for the Pixelbook Go that other Chromebooks in the same price range are more capable.

Take the Acer Chromebook Spin 13, our current favorite luxury Chromebook—while it's not as thin or light as the Pixelbook Go, it can be outfitted with similar specs, includes a stylus that lives in its chassis, has an FHD+ display with a 3:2 aspect ratio, and offers solid performance all for around $725. You'll get more for your money, if you can sacrifice a bit in the design department, than you would in our $849 Pixelbook Go review unit.

Performance

Our $849 Pixelbook Go review unit runs on an Intel Core i5-8200Y processor, 8GB of RAM, and 128GB eMMC storage. Those are the exact same specs of the $999 Pixel Slate that we reviewed last year. When asked why the device has 8th-gen CPUs rather than anything newer, Google representatives only said that they opted for 8th-gen, Y-series processors so the Pixelbook Go could have a fanless design just like the Pixel Slate had.

In addition to keeping the Pixelbook Go thin, a fanless design also minimizes heat and noise. In my time using the Pixelbook Go as my primary laptop, I never felt it get more than a touch warm, even while running benchmark tests. It also produces little to no noise, making it an even better on-the-go device (there are no whirring fans to disturb those around you in a coffee shop, a noticeable difference between the Pixelbook Go and the Acer Chromebook Spin 13 that I referenced earlier).

The Pixelbook Go performed almost identically to the Pixel Slate, making it a powerful Chrome OS machine but not always more powerful than the original Pixelbook or even other high-end machines like the Acer Chromebook Spin 13. Depending on what you plan on using the Pixelbook Go for, you may not need to upgrade to a Core i5 model. Having used Chromebooks with all levels of processors from Pentium to Core i7, I know I'd be able to use our Core i5 review unit as an on-the-go laptop very easily with little to no disruption in my workflow as far as performance is concerned.

In fact, I could probably use the base, Core m3 model without sacrificing much, and in general I recommend Core m3 Chromebooks to most users. If your goal is to use the Pixelbook Go as Google intended—a Chrome OS laptop built specifically for on-the-go use—the Core m3 option will have enough power to run a number of Chrome tabs and Android apps simultaneously. The base model is made even better by its 8GB of RAM—the most affordable Chromebooks typically come with just 4GB of RAM, which is only suitable if you're not doing a lot of multitasking, or can withstand the machine being less efficient in that area.

We should also mention the predicted update schedule for the Pixelbook Go: while the timeline is still being finalized, Google estimates it will push regular updates to the Pixelbook Go (and other Amber Lake-based Chromebooks) through June 2026. That falls roughly in-line with Google's blanket rule that "hardware platforms" will receive 6.5 years of Chrome OS updates before the company essentially forces them into obsolescence (from a software perspective). You can still use Chromebooks that are past their AUE date, but they won't get the newest software and firmware features, nor will they receive technical support from Google.

Battery life

Google also wanted to improve upon the original Pixelbook's battery life and it did so in the Pixelbook Go. The new laptop lasted an average of 722 minutes, or about 12 hours, on our Wi-Fi test, and an average of 369 minutes, or just over six hours, on our webGL test. Regardless of how you're using the Pixelbook Go, you can safely expect at least one to three hours more battery life than you'd get when using the original Pixelbook, which is a solid improvement. It's also convenient that both of the Pixelbook Go's USB-C ports support charging, so if you already have a USB-C device in your arsenal, you won't have to carry around an extra charging cable when you're out and about.

A new addition that doesn't stand out

Chromebooks aren't just the default laptop you get when you only have $250 to spend. The time where Chromebooks fit into that small box has passed, and the Pixelbook Go adds to what is becoming a large subsection of Chromebooks that are designed for demanding work primarily done in a browser or whilst connected to the Internet. There's no shortage of $599 and up Chromebooks, and the Pixelbook Go, while appropriately placed in that category, doesn't do much to stand out from the rest.

The two most unique things about it are its Google-y design and the fact that its base model has 8GB of RAM. The latter is an easy pro for the Pixelbook Go, but the former is more nebulous. Design is ultimately subjective, but it's likely that those who love Google's design language will believe the Pixelbook Go to be superior to most other Chromebooks in terms of hardware. I don't think it's superior to all, but I do think it's one of the more elegantly designed Chromebooks you'll find today.

Ultimately, that minimalist design branded with a little "G" on the lid is what you're paying for because the rest of the Pixelbook Go is average. It performs well in every way you'd expect, but it doesn't it do anything extraordinary. I consider that acceptable for the $649 model, but that doesn't make it the best value Chromebook for the money (you can get an Asus Chromebook Flip C434T with identical specs for about $625). Price justification becomes even more difficult when you consider the higher-end configurations of the Pixelbook Go.

I wish Google had considered other ways to make the top-tier, $1,399 Pixelbook Go more valuable because there are plenty of ways to do so—all it would have had to do is look at the competition. Unlike Apple with macOS and MacBooks, Google doesn't have a monopoly on Chrome OS, so the Pixelbook Go has to compete with a bunch of other Chromebooks that offer more features and perks at similar prices.

That competition won't matter to Google hardware enthusiasts, but it's certainly important to Chrome OS enthusiasts looking for the best device for their needs and budgets. And after using the Pixelbook Go for nearly a week, I found myself wishing for a Pixelbook 2.0—I wish Google had come out with two new devices this year: the $649 Pixelbook Go with only two configurations (Core m3 and Core i5) and an updated Pixelbook priced at $999 or more with all of the things we loved about the original, plus new features and internals. Maybe we'll get that in the future, but for now, those considering the Pixelbook Go should only look closely at the two most affordable options. Otherwise, look to the original Pixelbook if you're ready to drop $999 or more on a Google-made Chromebook.

The Good

  • Thin-and-light, minimalist design.
  • Comfortable, backlit keyboard.
  • Good performance.
  • Base model has 8GB of RAM.
  • Increased battery life when compared to original Pixelbook.
  • More affordable starting price when compared to original Pixelbook.

The Bad

  • Glare-filled screen.
  • 16:9 screen aspect ratio.
  • No fingerprint sensor or pen support.
  • No microSD card.

The Ugly

  • Too expensive for what you get past the base model.

Forget the Galaxy Fold: This zigzagging foldable phone from TCL bends into thirds - CNET

tcl-tri-hinge-foldable-ifa-2019-22

TCL gives us a brand new foldable design we've never seen before.

Tyler Lizenby/CNET

I've opened and closed foldable phones hundreds of times by now. But even after reviewing the Galaxy Fold (twice), playing with Huawei's Mate X and bending slim concept designs, nothing has prepared me for TCL's prototype dual-hinged phone, which folds in three parts and opens into a huge, 10-inch tablet. 

The most remarkable thing about TCL's phone is that the hinges themselves move in different directions. The DragonHinge fold in, like a book, or like the Galaxy Fold, while the Butterfly Hinge folds the opposite way.

The two hinges create a zigzag shape as you open and close the device, a silhouette in Z. It looks like an accordion. Or a taco holder. And I have to get my greedy hands on it to give it a fold, one panel at a time: Open. Folded over once. Completely folded up into a triple-stacked sandwich so that the exposed panel becomes the TCL phone's "outer" screen. With this design, a single uninterrupted screen does it all.

Now playing: Watch this: This Galaxy Fold competitor folds in thirds

2:05

As with other foldable phones, the act of folding feels physical and visceral in a way that makes me appreciate the engineering feat of any company attempting to make devices whose screens bend in half.

Foldable phones are the next frontier in phone design, delivering at least double the screen space in a package that's practical enough to tote around. Unfolded, the large screens promise an expansive display for reading, watching videos, gaming and multitasking. Folded up, you can use them on the go. Despite very real fears over screen damage that could send lofty foldable ambitions crashing to the ground, device-makers are scrambling to push out their own new designs -- to bag reputation points as much as to capture buyers' attention.

It's into this mix that TCL is dropping its wild new prototype. Best known for making really good, affordable TVs, TCL is now aligning its phone business under the same brand. The company has already trotted out concept designs and announced its DragonHinge months before this particular dual-hinge effort. 

TCL's daring trifold prototype is just the start

TCL's prototype design doesn't have a name, a price or a target window for production. It doesn't even have a working screen. All that will come. For now, I'm mesmerized as I work the hinges with my hands, and imagine what it'd be like to use a triply folding device. 

Folding one panel under, for example, could turn a portion of the screen into a digital keyboard while you use another part as the display. When you fully close the phone, you'd be able to use it as a really chunky handset.

Yes, you'll see creases when it's open -- and no, we still don't have bendable glass to better protect the display. That raises questions about the wear and tear on a device with a plastic cover material that's exposed to sharp objects, damage from pressure and the elements, like rain and dust. These are the same issues that plagued the $1,980 Galaxy Fold and spurred Samsung to retrofit its foldable phone to make it sturdier than its first attempt.

tcl-tri-hinge-foldable-ifa-2019-4
Tyler Lizenby/CNET

For now, there's no consensus on what the "best" foldable phone design is, and that's what makes this all so exciting. We're in the Wild West phase where any prototype or concept goes, from the vertically folding Motorola Razr that CNET discovered will come out by the end of 2019, to the square foldable phone that Samsung's rumored to be building. 

Microsoft, too, has its bookish Surface Pro Duo slated for 2020 and Chinese brand Xiaomi wowed us with an early concept that has you folding back two side display panels behind a center panel.

When and if it becomes a real product, TCL's prototype will face distinct challenges with ensuring sturdy construction, a semiaffordable price and a sales plan to put the biggest foldable phone we've seen yet in front of real buyers. But enough reality for now. I let the teeming questions slide from my mind and give the Butterfly Hinge one more fold.

TCL trifold phone specs we know so far

  • Roughly 10-inch screen when fully opened
  • Four rear cameras
  • Front-facing camera
  • USB-C charger port
  • Iridescent finish
  • No headphone jack

Samsung announces more powerful Exynos processor without built-in 5G - The Verge

Just shy of two months after announcing the Exynos 980, Samsung has announced a new chipset, the Exynos 990. The new processor is built on Samsung’s 7nm process, and includes a Mali-G77 GPU that increases graphical performance or power efficiency compared to Samsung’s previous chip by up to 20 percent as well as an octa-core CPU that should be 20 percent faster.

While it seems strange to see two processors announced in such quick succession, the Exynos 990 seems to be targeted at a slightly different market. VentureBeat notes that it lacks the integrated 5G modem found in the 980, meaning it will be better suited to 4G devices. It’s the faster processor of the two, but Samsung would need to pair it with a separate modem — like the 5G Exynos Modem 5123 that it also announced today — if it wants to use it in a 5G device.

The Exynos 990 also features support for displays with up to a 120 Hz refresh rate, as well as up to six cameras with a maximum resolution of 108 megapixels, like the ISOCELL Bright HMX sensor Samsung announced back in August.

The 5G Exynos Modem 5123, meanwhile, is a new 5G modem that’s also built using a 7nm process. It supports both kinds of 5G, sub-6GHz and mmWave, the latter of which was missing when Samsung announced its previous Exynos 980 chip with an integrated 5G modem. When connected to a 5G network, Samsung says the Exynos Modem 5123 supports a maximum download speed of 5.1 Gbps on sub-6GHz, and 7.35 Gbps on mmWave.

Samsung doesn’t say which phones the new chips will come to first, but with mass production expected to begin later this year there’s speculation that they’ll find their way into some of Samsung’s Galaxy S11 devices early next year. However, based on past trends they’re unlikely to be found in Samsung’s devices in the US or China, which have historically used Qualcomm’s chips.

Google says it's achieved quantum supremacy - Engadget

Google is standing by its claim that it's achieved quantum supremacy -- marking a major milestone in computing research. The company first made the claim back in September, and while disputed by competitors, Google's research paper has now been published in the scientific journal Nature.

Quantum supremacy is a big deal, because it encapsulates the ability of quantum computers to solve problems that current technology couldn't even begin to attempt. Google's paper explains how its 53-bit quantum computer -- named Sycamore -- took just 200 seconds to perform a calculation that would have taken the world's fastest supercomputer 10,000 years.

In theory, this capability opens a lot of doors to future technologies, such as designing better batteries and medicine, or minimizing emissions from farming chemicals. It could also help to advance existing technologies such as machine learning. However, Sycamore's feat has almost no practical use at this stage -- it was designed simply to show that a quantum computer could perform as expected.

Nonetheless, it's an important first step towards a technology that could have a major impact on our lives -- even if that's still some years away. In an interview with MIT Technology Review, Google CEO Sundar Pichai likened the experiment to the first flight by the Wright Brothers. "The first plane flew only for 12 seconds, and so there is no practical application of that," he said. "But it showed the possibility that a plane could fly."

Google quantum computer leaves old-school supercomputer in the dust - CNET

Google's Sycamore chip powers a quantum computer

Google's Sycamore chip powers a quantum computer

Google

A Google quantum computer has far outpaced ordinary computing technology, an achievement called quantum supremacy that's an important milestone for a revolutionary way of processing data. Google disclosed the results in the journal Nature on Wednesday. It came after more than a decade of work at Google, including the use of its own quantum computing chip, called Sycamore.

"Our machine performed the target computation in 200 seconds, and from measurements in our experiment we determined that it would take the world's fastest supercomputer 10,000 years to produce a similar output," Google researchers said in a blog post about the work.

The achievement, which leaked into the limelight in September with a premature paper publication, doesn't mean the beginning of the end for classical computers, at least in the view of today's quantum computing experts. Quantum computers are expected to be good at some particular chores -- optimizing investment portfolios and developing new drugs at the molecular level, for example -- but not most of what we do today on computers.

Google's result does offer evidence, though, that quantum computers could break out of research labs and head toward mainstream computing.

Quantum computing researcher Scott Aaronson likened the step to landing on the moon in terms of momentousness. And Google Chief Executive Sundar Pichai called it a "big breakthrough" in a tweet Wednesday.

A vast industry is devoted to improving classical computers, but a small number of expensive labs at companies such as Google, Intel, Microsoft, Honeywell, Rigetti Computing and IBM are pursuing general-purpose quantum computers, too. They're finicky devices, running just a hair's breadth above absolute zero to minimize the likelihood they'll be perturbed. Don't expect to find quantum computers are not the kind of thing you can expect to find on your desk.

Google's speed test has applications to computing work like artificial intelligence, materials science and random number generation, the paper said. "

However, physicist Jim Preskill, who came up with the term quantum supremacy in 2012, dashed some cold water on that idea. Google's chosen test was good for showing quantum computing speed but "not otherwise a problem of much practical interest," Preskill said in October after the paper's premature release.

Quantum vs. classical computers

Nearly every digital device so far, from ENIAC in 1945 to Apple's iPhone 11 in 2019, is called a classical computer. Their electronics rely on logic circuits to do things like add two numbers and memory cells to store the results.

Google quantum computer

Google quantum computer looks nothing like a conventional machine. When running, all this complexity is hidden away and refrigerated to near absolute zero.

Quantum computers are entirely different, reliant instead on the mind-bending rules of physics that govern ultrasmall objects like atoms.

Where classical computers store and process data as individual bits, each a 1 or a 0, quantum computers use a different foundation called a qubit. Each qubit can store a combination of different states of 1 and 0 at the same time through a phenomenon called superposition. Told you it was weird.

Not only that, but multiple qubits can be ganged together through another quantum phenomenon called entanglement. That lets a quantum computer explore a vast number of possible solutions to a problem at the same time.

Exponential speedups

In principle, a quantum computer's performance grows exponentially: add one more qubit, and the number of solutions you can examine in one fell swoop doubles. For that reason, quantum computing engineers are working to increase the number of qubits in their machines.

"We expect that their computational power will continue to grow at a double-exponential rate," the Google researchers said in their paper. That's even faster than the single exponential improvement charted for classical computer chips by Moore's Law.

Google's machine had 54 qubits, though one wasn't working right, so only 53 were available. That happens to match the number in IBM's most powerful quantum computer.

But qubit count isn't everything. Unavoidable instabilities cause qubits to lose their data. To counteract that problem, researchers are also working on error-correction techniques to let a calculation sidestep those problems.

IBM challenges Google's quantum results

IBM is a major quantum computing fan, but it questioned Google's prematurely released results in a blog post Monday.

"We argue that an ideal simulation of the same task can be performed on a classical system in 2.5 days and with far greater fidelity," IBM researchers wrote. They suggested different algorithms and a different classical computer design in a preprint paper of their own.

Google said it welcomes improvements to quantum computer simulation techniques but said its overall result is "prohibitively hard for even the world's fastest supercomputer, with more double exponential growth to come. We've already peeled away from classical computers, onto a totally different trajectory."

Intel didn't offer an opinion on Google's results, but did say quantum supremacy is "a strategic benchmark." 

"We are committed to moving quantum from the lab to commercialization," said Jim Clarke, Intel Labs' director of quantum hardware, in a statement.

Cracking your encrypted communications? Not yet

One quantum computing ability, mathematically proved with an idea called Shor's algorithm, is cracking some of today's encryption technology.

However, that will require vastly larger quantum computers and new technology breakthroughs to deal with error correction.

"Realizing the full promise of quantum computing (using Shor's algorithm for factoring, for example) still requires technical leaps," the researchers said in their paper.

And at the same time, the US government and others are working on "post-quantum" cryptography methods to withstand quantum computing cracking abilities.

So for now at least, quantum computing, while radically different, isn't blowing up the tech industry.
