Galaxy Book 2: Cross-platform benchmarks
Samsung’s choice to move from an Intel Core i5 CPU to a mobile chip shifts the emphasis from performance—where the first Galaxy Book did very well—to battery life. It’s our first test of the new, next-gen Qualcomm Snapdragon 850, which promises “multi-day” battery life as well as more speed.
Does the new Snapdragon 850 have enough oomph for you to be happy? Well, it depends. Due to the anemic processor and low system memory, web browsing is generally acceptable with limited tabs. Office work, like word processing, is just fine. YouTube videos are child’s play—there’s a special video decode engine in the Adreno graphics chip, and a 1080p video consumed about a third of its resources. Games? Don’t count on it, especially anything really modern.
What our tests indicate so far is that the $999 Galaxy Book 2’s performance is in the neighborhood of the $399 Microsoft Surface Go, which is a “good-enough” small-form-factor tablet in its own right. Remember, too, that the Book 2’s battery life pretty much blows everything else away—it’s over twice that of the Surface Go’s!
One caveat: Samsung says it will ship its new Galaxy Book 2 with Windows 10 Home in S Mode, but it inexplicably shipped ours with Windows 10 Home enabled—which we noticed after running several of the browser-based tests we’d normally use for testing a Windows 10 S PC. It’s possible that running Windows 10 Home rather than Windows 10 Home in S Mode may invalidate these results—S Mode is supposedly a more optimized environment, but it doesn’t allow for any apps outside of the Microsoft Store. But they seem consistent with our more traditional benchmarks.
Because these are browser-based benchmarks, we can compare the Book 2 to non-Windows devices, “first”-generation Snapdragon-powered PCs like the Asus NovaGo, and even Apple devices and an Android tablet. Note that though we didn’t have an opportunity to run our full suite of benchmarks for our original hands-on, we made sure we ran them all for this, our review. We were pretty sure that our initial tests would be indicative of final performance, but we were slightly mistaken—battery life actually increased. These tests reflect those numbers.
We’ve included both versions of the older Speedometer benchmark, designed to measure the responsiveness of web applications. (In real-world browser use, the Book 2 felt as responsive as a much more powerful laptop, especially when using Microsoft Edge.) Google’s deprecated Octane benchmark was also tested. In both cases, the Galaxy Book 2 lands at the top of the bottom (or lower middle, if you’re a glass-half-full sort of person), as seems to be the general trend for it.
Samsung Galaxy Book 2: PC benchmarks
As I noted in my review of the Microsoft Surface Go and Windows 10’s October 2018 Update, Microsoft’s Edge browser now feels fast and responsive—and with the Galaxy Book 2, you need all the help you can get.
There’s a real difference in how the Galaxy Book 2 feels in terms of the browser you use with it. I was able to open ten media-rich tabs in Edge, and the browser felt fast and responsive, able to navigate most pages within a second—even bouncing back to older tabs. Occasionally, the images would take a bit longer to load, though, I was able to scroll up and down the page. Oddly, it was slow to close the application.
Chrome, meanwhile, felt much, much slower, and pages took quite a while to open completely. That may have to do with how Chrome “sandboxes” each tab, and Chrome’s reputation for gobbling memory won’t help in a 4GB machine like the Galaxy Book 2. It’s a markedly different experience.
While the Galaxy Book 2 is a bit faster than the original Galaxy Book, it’s generally fairly slow for intensive, computational work. As we noted above, two tests—Cinebench and HandBrake—refused to run. (While they did on an older Snapdragon-powered PC, the Asus NovaGo, that laptop also used a beta version of Windows 10 in S Mode.)
We’ve compared the Galaxy Book 2 (in red) to a number of tablets, including the first-generation Galaxy Book, which we’ve highlighted as well (in orange). The gulf between the Intel Core i5 in the first generation and the Qualcomm Snapdragon 850 in the second generation is wide.
The PCMark Work test measures spreadsheet performance, Word processing, web browsing, and VOIP calls, which is pretty critical. The Home test, which adds some light gaming and image manipulation, puts some additional stress on the Adreno GPU.
We also tested the Book 2 with the PCMark Creative test, the most stressful of the three in terms of overall performance. It measures image manipulation and video editing, light gaming, and VOIP calls. Again, the Book 2 can’t keep up with Intel Core-powered laptops and tablets.
The 3DMark Sky Diver tests assesses how well a laptop or chip would do in 3D gaming performance. These results should tell you that gaming simply isn’t the Galaxy Book 2's emphasis. The Adreno GPU has no problem with video decoding, however, which isn’t measured here.
But wait! We finally come to the piece de resistance of the Samsung Galaxy Book 2, and the Qualcomm Snapdragon chips: battery life. This is why you should be interested in the Galaxy Book 2, and it’s here that it will pay you back in spades. We use a light meter to establish a standardized level of light output for comfortable viewing, then loop a 4K movie (with headphones connected and volume at its middle setting) until the battery expires. The Samsung Galaxy Book 2 delivers, and then some: 17 hours and 12 minutes of battery life. That’s almost in a league of its own.
One thing we don’t like, though: Supposedly the Galaxy Book 2 ships with a “Fast Charging” smartphone-style USB-C 1-amp charger. When Windows reports that it will require over 3 hours to charge the laptop, we have to wonder if Samsung should rethink the branding.
Conclusion: Buy it for the battery
The Samsung Galaxy Book 2 delivers fantastic battery life, marginal performance, a lovely display, and optional LTE. If you’re not doing much more with it than office work and web browsing, we see no reason not to buy it. We still encounter some apps that simply won’t run on a Snapdragon chip, though, and we’re hesitant to recommend anything that may yield a similar experience. Buying a notebook or tablet that can’t run the one app you need is a frustrating experience.
Though it never quite crested our Editor’s Choice awards, the original Galaxy Book was a solid all-round effort. Samsung’s leaned heavily toward battery life this time around, at the expense of performance and slight app compatibility. Don’t forget the price, either—$999 isn’t bad, which includes the keyboard and pen.
Performance issues left a sour taste in my mouth, as did the refusal to run a couple of apps. But I was reluctant to give back back the Galaxy Book 2, simply because I prize a laptop that allows you to work on the go with without worrying about running out of juice. In short, our recommendation remains essentially the same as the Asus NovaGo: If you can accept the risks and a bit of frustration, and prize battery life above all else—then yes, the Galaxy Book 2 is definitely the tablet for you. If you’re unsure, you may as well wait—faster Snapdragon chips are on the horizon.
