REVIEW: SAMSUNG GALAXY BOOK S
Price: £999 (inc VAT) from fave.co/2V5GDcy
The Samsung Galaxy Book S is worth a look for several reasons: This ultralight, fanless 13.3in clamshell combines superb battery life with WWAN connectivity that compels you to work on the go. Priced at £999, it’s affordable, too.
The Galaxy Book S boasts Qualcomm’s latest Snapdragon 8cx chip, an ARM processor that trades middling performance for a crazy 16 hours of battery
life. Samsung’s learned what users like: The laptop adds a decent fingerprint reader, USB-C ports, and a 3.5mm headphone jack.
It’s the best Qualcomm-powered PC we’ve seen in some time, including the Microsoft Surface Pro X, but the standard performance caveats of Snapdragon notebooks remain. Meanwhile, some X86-based machines have improved so much in battery life that they’ve stolen Qualcomm’s claim to fame.
Super-thin, super-light
At 961g, the Samsung Galaxy Book S lands in tablet territory (including a keyboard). Thanks to its anodized aluminium construction, you’d have to call it one of the most impressive ultralight PCs around. We received the Mercury Grey colour from Samsung for review, though
the pinkish ‘Earthy Gold’ is also available. On the desk, the Book S opens with a finger, and the display reclines to about 45 degrees. It’s solid, too: I perceive no keyboard flex while typing, and the display barely flops or wobbles while moving the keyboard around.
Power on the Galaxy Book S by tapping the button to the upper right of the keyboard, a relatively small key that also conceals a fingerprint reader. (You’ll need to power on, then tap again to authenticate.) I was sceptical about such a tiny sensor, and it sometimes required a second tap or the repositioning of my finger. Still, I never had to default to a secondary PIN code or password to access the Galaxy Book S.
Like some of Acer’s Swift notebooks, the Book
S is thin enough that the chassis actually bulges to accommodate the pair of USB-C ports (one on either
side). They’re not Thunderbolt-enabled, though they are USB 3.1 Gen 2 (10Gb/s). Forget USB-A or any legacy ports, save for a 3.5mm jack.
Samsung’s charger is small enough to confuse it with your smartphone’s. If they both use USB-C you could try to swap them, but the Galaxy Book S will complain. The
laptop ships with quick-charging capabilities, but those may go away if you use another charger.
The sparse port selection is supplemented by the hybrid expansion slot drawer on the underside, with trays for both microSD and the LTE SIM.
The Galaxy S display is a 13.3in TFT 10-point touch display. It pushes out a generous 355 nits maximum, letting me find a comfortable (though somewhat shady) outdoor site to work. A separate USB-C hub let me output 4K/60-fps video through HDMI to an external 4K display with no issue.
The display bezels are slender on the top and sides (about an eighth of an inch), while the bottom bezel is a chunkier 0.75 inches deep, wide enough to house a 720p webcam. It’s good enough for everyday use, though it lacks special features such as biometrics or a physical shutter.
The glossy display, while beautiful, attracts fingerprints and smudges like an unwatched burrito lures a hungry Labrador retriever. Working outside quickly becomes an exercise in dodging reflected background objects, too.
The quality audio options are an unexpected delight. The pair of downward-facing speakers blew me away – almost literally – as perhaps the loudest I’ve heard in some time. Samsung says the Galaxy Book
S is tuned by AKG, with Dolby Atmos software under the hood for audio enhancement. Sure, the bass isn’t great – not unusual in laptops – and Dolby appears to downplay portions of the audio soundscape to provide a richer overall sound. The Dolby Atmos software provides built-in presets that detect and auto-adjust the
audio to accommodate a streaming movie, say, versus playing a game. There’s also a manual equalizer.
Keyboard and typing: Just okay
I prefer laptop keyboards with fairly substantial travel, something the Galaxy Book S lacks. Each key is firm and resilient, however, and wide enough to provide a comfortable landing space. The three levels of backlighting (plus off), aren’t particularly powerful.
The standard layout offers small touches: The F11 key doubles as a shortcut to the desktop, for instance, minimizing all other windows. Other function keys open the Task View and the alternative ‘project’ options to external displays. There are also dedicated Insert and Delete keys. The Precision touchpad is large and spacious, located directly
underneath the space bar. The top isn’t clickable, although there’s probably enough room otherwise to make up for it.
Real-world performance: Decent, for what it does
I spent the better part of two weeks using the Samsung Galaxy Book S, either tethered to a desk or on the go. I can safely say the Galaxy Pro S works best within Microsoft’s UWP environment of built-in Windows 10 apps, plus Office work, web browsing and the like.
By asking you to buy the Galaxy Book S through a wireless carrier, Samsung is really playing up the ‘Always Connected’ aspect of Snapdragon PCs. I drove around my hilly small town, sporadically pausing to browse, play back video, and conduct speed tests. I
toted along the Microsoft Surface Pro X with an eSIM inside for comparison.
Using Internet speed tests, the Galaxy Pro S averaged about 30- to 40Mb/s downstream across many locations, while the Surface Pro X ranged from over 100Mb/s downstream to just a few hundred kilobytes. In each location, I was able to stream Netflix with no issues, although the stream hiccuped a time or two near the Bay.
Because of the fundamental difference in the ARM architecture underlying Qualcomm’s Snapdragon processor, any PC with one inside also ships with a number of caveats. While the Snapdragon 8cx can run native 32-bit and 64-bit apps encoded specifically for its ARM64 architecture, they’re a rarity in the Windows world. Instead, Snapdragon PCs like the Samsung
Galaxy Book S are restricted to 32-bit apps encoded for the X86 architecture used by Intel Core and AMD Ryzen processors, via emulation. At this point, 64-bit X86 apps can’t run on a Snapdragon PC at all.
In the real world, this plays out in odd and exasperating ways. I couldn’t use the 32-bit binary version of our company VPN, as it never installed correctly. I tried Microsoft’s ‘new’ Edge, which supports ARM64, including its curated suite of extensions as well as the Chrome Web Store. Paired with an ad blocker, web pages became as responsive as I would expect with an X86 machine.
Some advocate using Progressive Web Apps (PWAs) as a hedge against the relative lack of native apps for Snapdragon processors. They’re essentially web pages that you can dock to your Start menu as regular apps, and it’s really up to you to go this route or just bookmark Spotify’s web player, say, in a tab.
Also using Edge, I was able to play back a test 4K/60fps YouTube video on an external display. When I tried to load a 4K video via the Netflix site, however, the previews rendered normally but the video wouldn’t play. The Netflix app via the Microsoft Store played the 1080p version of my movie just fine.
In general, Snapdragon PCs are best for web browsing, Office work, video, and some very minimal game playing. Microsoft Office was a tad slow, as we show in our benchmarks below, but otherwise normal.
It’s refreshing to see playable games show up within the Microsoft Store app, under the Game Pass heading. Unfortunately, the only games available currently were 2D sprite-based games (Blazing Chrome
(fave.co/2xtFpig), among others) that ran slowly on an external 4K monitor. On the native Galaxy Book S display, everything ran fine – unsurprising, really, as the graphics were of 1980s arcade quality.
Benchmarks: Its Achilles heel
The limitation on 64-bit binaries hamstrings our ability to benchmark the Samsung Galaxy Book S fully, though a small subset of benchmarks help us define what the Samsung Galaxy Book S can do in terms of Office and graphics capabilities.
We were interested to compare the Qualcomm Snapdragon 8cx processor to the more powerful semi-custom Microsoft SQ1 chip inside the Microsoft Surface Pro X. Qualcomm announced the Snapdragon 8cx in late 2018, and while it doesn’t include a ‘prime core’ for burst workloads, it maintains the same four ‘performance’ cores running at 2.84GHz, balancing those against four ‘efficiency’ cores at 1.8GHz.
While the SQ1 boasts a more powerful CPU and GPU combination – including an Adreno 685 GPU, as opposed to the Adreno 680 inside the Galaxy Book S – it also has to render the Surface Pro X’s 2,880x1,920 display, versus the more conventional 1080p display within the Galaxy Book S.
We have three benchmarks for evaluating the Galaxy Book S as a PC. The first, PCMark 10’s Apps suite, uses the actual Microsoft Office suite to measure app loading times, and also how quick and responsive the Galaxy Book S is with spreadsheets, word processing, and the like.
We ran the test on a recent Core i7-based (Whiskey Lake) Lenovo ThinkPad X1 Carbon as well. With a score of 5,951, the X1 Carbon easily surpasses the 4,615 Samsung’s Galaxy Book S recorded. But does this number matter in the real world? Yes, and no.
The PCMark 10 Apps test offers a more granular breakdown of its results. It took the Lenovo X1 Carbon 2.2 seconds to calculate one test, a stock history metric, that the Galaxy Book S required 7.1 seconds to complete. Simply opening Word required 1.9 seconds for the X1 Carbon, 2.5 seconds for the Galaxy Book S. Opening a test document in Excel required
2.79 seconds for the X1 Carbon, and 5.4 seconds for Samsung’s PC. Another number seemed significant: while the X1 Carbon could play back H.264-encoded video at a full 30 frames per second, Samsung’s Galaxy Book S couldn’t get past 24.6fps.
We use the PCMark 8 Creative benchmark to evaluate how laptops like the Galaxy Book S will perform in photo editing, video editing, light gaming, and more. The Galaxy Book S posted one of the lowest scores.
A similar test, the WebXPRT 3 benchmark, runs on a web page to measure how well the laptop can perform in some light editing and multimedia tasks. Again, the Samsung Galaxy Book S performs a bit slower than the Surface Pro X.
Finally, we use 3DMark Night Raid, a crossplatform benchmark that can run on top of ARM as well as X86 systems. Here, the slightly slower Adreno GPU within the Galaxy Book S puts it slightly behind the Surface Pro X.
Performance matters, but battery life is a Snapdragon PC’s strength. We loop a 4K video (rendered in 1080p on the Galaxy Book S screen) and play it back until the battery expires. The Samsung Galaxy Book S achieved a whopping 16 hours of battery life, enough for a whole day’s work and a whole lot more.
I also ran the PCMark 10 Battery rundown test, which loads and runs Office apps periodically until the battery runs down. That generated 9 hours and 51 minutes of battery life. While your mileage will vary, the conclusion we can reach from both is that you’ll receive exceptional battery life from the Galaxy Book S.
Verdict
With Qualcomm-based PCs, comparing battery life versus price is probably the most relevant metric, as long as performance is adequate. From that perspective, the Galaxy Book S delivers. The Galaxy Book S also packs in features that show Samsung carefully thought through the mobile computing experience: a bright screen, fantastic battery life, ultra lightweight, plus the connectivity – all affordably priced. It works well within a limited ecosystem of Office apps, web browsing, Windows’ own UWP apps like Mail and Calendar, and a few other options. Unfortunately for Qualcomm, it’s no longer the only game in town when
it comes to long battery life. The original, outdated Microsoft Surface Laptop outperforms today’s Galaxy Book S, and also delivers over 11 hours of battery life. But the recent HP Spectre x360 13t delivers almost 16 hours of battery life on top of a similar 1080p screen, with a powerful 10th-gen Core i7 chip under the hood – and for a similar price. (Because of the app compatibility issues, we can’t directly compare the two on more than a single performance benchmark, but it’s still telling: Samsung’s Galaxy Book S generates a PCMark Work score of 2,121, while the Spectre x360 13T is 79 percent faster, at 3,807.) The great failing of the Microsoft Surface Pro X is that it couldn’t deliver
on performance, price, or battery-life. While Samsung’s Galaxy Book S can’t overcome the Snapdragon’s inherent performance deficiencies, it satisfies the other two criteria. Mark Hachman
