Microsoft Surface Pro 8 review: A superior tablet with baffling quirks

Microsoft’s Surface Pro 8 tablet arrives as Windows 11 goes out the door. Microsoft has already shipped one tablet this year, the Surface Pro 7+, which rose to the top of our roundup of the best Windows tablets of 2021. Can the Surface Pro 8 improve upon it?

Yes and no. The Surface Pro 8 boldly strides forward with a larger, higher resolution, faster screen, a revamped inking experience spearheaded by the optional Surface Slim Pen 2, and a pair of Thunderbolt ports that supplement the legacy Surface Connect charger. It’s a dramatic reworking of the iconic Surface Pro tablet line, and that’s enough to grab your attention.

If only we could leave it here. Put simply, we can’t be entirely certain how well the Surface Pro 8 performs because of some wildly varying results in our performance tests. Battery life varied wildly, too. We’re pretty sure that the Surface Pro 8 represents an upgrade to the Surface Pro 7+ and Surface Pro 7, but what we’ve seen doesn’t suggest that it will outperform the competition. You’ll have to look more closely at the intangibles to make your decision.

Microsoft Surface Pro 8 specifications

For now, there’s one important change in configuration between the Surface Pro 7+ for Business and the latest Surface Pro 8: The Surface Pro 8 lacks an inexpensive Core i3 option, and thus its base price is $100 higher, at $1,099. The good news is that all of the Surface Pro 8 options Microsoft is selling should offer enough computational power and memory for any buyer. Our review unit also lacked cellular capabilities, so we didn’t test those.

Microsoft continues to sell the Surface’s companion keyboard and the pen separately, though there’s an explicit keyboard/pen bundle that Microsoft will sell for an additional $279.99. The Surface Pro 8 has been designed with the new Surface Slim Pen 2 in mind, however, and Microsoft says you’ll experience reduced e-ink latency/lag if you use it.

Two years ago, the Surface Pro X showcased the future of Microsoft’s Surface Pro tablet lineup. Today’s Surface Pro 8 has been redesigned in its image, with a pair of Thunderbolt ports and an integrated charging cubby for the Surface Slim Pen 2. That can be a little disconcerting for long-term Surface owners, as Microsoft has moved things around. The power button is now on the side of the tablet, for example.

Though the Surface Pro 8 is now slightly heavier and chunkier than its predecessors, you’ll need to compare them side by side to notice. Otherwise, the Surface Pro 8 looks the same as it emerges from the box. Hopefully you’ve already purchased the Surface Pro Signature Keyboard to take full advantage.

Like other Surface Pro devices dating back to the Surface Pro 3, the tablet reclines to nearly horizontal. The Surface Pro’s Signature magnetic keyboard, though, clasps it firmly. If that matters to you, buy a Surface Pro 8. Rival tablets don’t invest enough in the magnetic connection, and a tablet on your lap already risks flipping backwards over your knees.

Microsoft ships the Surface Pro 8, as it ships most of its Surface devices, dialed down to minimal performance levels. Though you give up a bit in terms of performance, this also means that the Surface Pro 8 rarely engages its cooling fan, and it only does so very quietly when necessary. (You can adjust the performance within the Windows 11 Settings menu, specifically System > Power & battery.) Narrow grillwork runs along both sides of the tablet, providing cooling. Typically, Surface tablets get warm to hot along the upper rear panel, and the SP8 is no exception.

With the Surface Pro 8, Microsoft is introducing a slightly larger 13-inch (2,880x 1,920) multitouch “PixelSense Flow” display that preserves the 3:2 screen ratio, versus the 12.3-inch (2736×1824) displays we’ve traditionally received as part of the Surface Pro lineup. Originally, Microsoft told us that the PixelSense Flow display would dynamically shift back and forth between the standard 60Hz refresh rate and a new 120Hz refresh rate, a feature known as Dynamic Refresh Rate. Higher refresh rates are easier on the eyes and would also improve inking, as the pen’s ink would “flow” more smoothly onto the screen.

Microsoft’s Dynamic Refresh Rate feature didn’t make it to the Surface Pro 8, unfortunately. Instead, Microsoft locked the refresh rate at 60Hz, though you can manually adjust it via the Settings menu (System > Display > Advanced Display) to the higher 120 Hz setting. Doing so would imply that your battery life would decrease, but we didn’t experience that. We’ll talk more about this during our performance tests, specifically the battery life section.

With the Surface Pro 8, the Surface Pro line makes a major transition to Thunderbolt, an enhanced I/O capability that has existed on rival notebooks and tablets for some time. The Surface Pro 8 includes a pair of Thunderbolt ports on one side, and has done away with the older USB Type-A port entirely. (Unlike the Surface Pro X, Microsoft has thankfully included a headphone jack, as well.) This allows the Surface Pro 8 to connect to a small but growing ecosystem of Thunderbolt docks, and charge from them too—provided that they’re powered. That gives SP8 buyers the option to either charge directly from the included 65W Surface charger, or tap into a Thunderbolt dock.

The sacrifice? Microsoft has done away with the microSD slot for this generation, a tacit push for people to upload their photos directly to the Microsoft OneDrive cloud. If you need a physical microSD port, you have a number of great USB-C dongles to choose from.

Audio

We didn’t hear any substantive qualitative differences between the Surface Pro 8 and earlier Surface tablets, but the speakers are indeed louder: they’re now 2W speakers, versus the 1.6W speakers used by the Surface Pro 7+. Like the earlier model, they also use Dolby Atmos, which is built in and not really adjustable by the user outside of the normal audio settings. Our Surface Pro 7+ review noted that the speakers sounded somewhat flatter and softer, and it appears that Microsoft has rectified this in the Surface Pro 8.

In general, the audio is certainly among the better options for tablets, and sounds as good or better than some laptops. You won’t need headphones to enjoy music on the Surface Pro 8.

Typing experience and keyboard

Microsoft’s Surface Pro Signature Keyboard, sold separately, doesn’t seem to be anything different than what Microsoft has offered in conjunction with past Surface Pro tablets. As noted above, the magnetic hinge clasps the keyboard tightly to the tablet, freeing you of the anxiety of working on your lap. On a desktop, the Surface Pro 8’s keyboard feels comfortable, put simply, with a satisfactory amount of key travel and resilience. You should be able to the use the keyboard comfortably for an entire day without any additional strain on your wrists or fingers.

The touchpad also appears to have remained unchanged. It’s actually clickable for almost the entirety of the trackpad, though you’ll have to exert an unreasonable amount for force at the top of the trackpad for the clicks to register. Though a bit plasticky, the trackpad is comfortable to use.

What’s new for the Surface tablet line is that the Surface Pro 8’s new Signature Keyboard includes a pen cubby for the Slim Pen 2, which appears to be the future of Microsoft’s pens. As we noted in our best tablet roundup, not every tablet keyboard that incorporates these new pens has a strong magnetic connection. The keyboard folds up, too, holding the pen securely while charging it. It’s a great design and completely eliminates the risk of losing a pen while the Surface Pro 8 is stored inside your bag or backpack.

Inking

Like the Surface Laptop Studio, inking is a priority on the Surface Pro 8. The Surface Pro 8 uses the Microsoft Pen Protocol in conjunction with the Surface Slim Pen 2. While I’m not a professional illustrator, my impression is that using Microsoft’s two-button Surface Slim Pen 2 is more accurate on the Surface Pro 8, perhaps in part because the screen offers more pixel density than the Surface Laptop Studio. Pairing the Slim Pen 2 is a breeze, so much that it seemed like the pen paired as soon as I connected the keyboard. You can launch apps by pressing a button, and “erase” just by rubbing the top of the pen against the screen.

The Slim Pen 2 also includes haptic feedback, so that you’ll “feel” interactions with shapes on Microsoft Whiteboard, for example. This may in fact be an assistive technology dressed up as a new consumer feature, but I wouldn’t buy a Slim Pen 2 for this.

Mark Hachman / IDG

Don’t discount the rechargeable pen, either, or its cubby! The days of trying to hunt down a AAAA battery for your Surface Pen are over. (Microsoft says that earlier Surface Pens will still work, but that you won’t see the same reduced latency as you will while using the Surface Slim Pen 2.

I manually adjusted the display refresh rate to 120 Hz to see the improved inking benefits, something that Microsoft had originally pledged that it would do dynamically. In any case, I didn’t see any line offsets, where ink flows from a different location from where the pen touches, even with the pen at an angle. There is still a tiny bit of ink latency as you move about the page, but, to me, it wasn’t significant. It also appears that the the pen jitter—where the pen’s lines ripple back and forth—is less than the Surface Laptop Studio or previous Surface Pro tablets. While we didn’t compare the inking ability to a dedicated Wacom tablet, it’s fair to say that the Slim Pen 2 offers an impressive inking experience.

Camera

As the company behind the Teams videoconferencing software, Microsoft intrinsically understands that people need to look good on camera during meetings or just chatting with friends. Though the Surface Pro 8’s user-facing camera still shoots just 1080p video, Microsoft has added ambient color and lighting sensors, too. The latter sensor does a better job of highlighting your image using the proper exposure, while the color sensor will automatically adjust the color of your screen to compensate for the ambient light.

Unfortunately, if the color sensor’s job is to show the webcam’s subject in the best light, it needs some work as the image below indicates.

Mark Hachman / IDG

Microsoft also enhanced its rear-facing camera, too, adding a 10Mpixel camera sensor, up from 8MP. We’re not the sort that takes photos with a tablet, but the added resolution certainly can’t hurt.

We were hoping that the Windows Hello 2.0 feature that Microsoft disclosed to us would be enabled on these machines. Windows Hello 2.0 supposedly can interpret your face even with a beard, glasses, or an N95 mask on. We tested the latter and…no dice. Windows couldn’t set up a new face profile with a mask on, and couldn’t recognize me with one on, either.

Performance

From a performance standpoint, the Surface Pro 8 is somewhat baffling. In places, our benchmarks show it to be faster than the Surface Pro 7+, but in others performance is drastically reduced. Under certain conditions, our results aren’t consistent; in others, they are. Right now, our working theory is that the Surface Pro 8’s cooling isn’t quite up to snuff, given that the fan sounds like it hardly ever turns on. Otherwise, this may demonstrate some early bugs that Microsoft has yet to work out.

From a usability standpoint, however, the Surface Pro 8 performs well. Our 4K streaming test video rendered dropped just 8 frames out of 10,000 or so, which means that video will stream jitter free even at high resolutions. With the same GPU as the Surface Pro 7+, you should expect comparable gameplay if you choose to go that route—plan on playing games at 1080p settings on High. This is a business and inking tablet, though, first and foremost.

We’ve compared the Microsoft Surface Pro 8 to the Surface Pro 7+ and Surface Pro 7, of course, as well as some of the other tablets in our recent tablet roundup. The key points of comparison are the Dell Latitude 7320 Detachable and the Lenovo ThinkPad Detachable Gen 1, which directly compete against the Surface Pro 8. We’ve highlighted those tablets with a lighter shade of blue in the charts in this section. Technically, the Surface Go 2 is also a smaller tablet competitor. We’ve also added notebooks like the Microsoft Surface Laptop 3 and Surface Laptop 4 as additional points of comparison

We use the PCMark test to measure how the tablet will fare under general computing workloads. The test measures videoconferencing, word processing, some light gaming, CAD work, application startup, and more. Here, the Suface Pro 8 performs up to expectations, with increased gen-over-gen performance.

It’s the Cinebench R15 test, however, where things started to go off the rails. The Cinebench R15 test measures the CPU’s performance, either running just a single processing thread or all of the cores/threads at once. You could almost call the benchmark iconic at this point, as it’s been used to test desktop PCs, gaming PCs, workstations, and more.

In the multicore tests, the Surface Pro 8 began by recording a score of 867, nicely above the 776 score that the Surface Pro 7+ recorded. But then the scores kept decreasing: 732, 723, 453, 449, and so on. The last five benchmarks we ran were about half the performance of the Surface Pro 7+. I never run the tests in succession, either: I interject “cooling down” periods of usually 12 minutes or more, and I ran the tests at different times of the day, in an air-conditioned environment. I reported my results to Microsoft and asked for comment, but didn’t hear back by press time. In all, our scores ranged from a low of 453 to a high of 867, which is crazy. Single-core scores varied from 149 to 185, for an average of 163, which is also lower than the Surface Pro 7+.

Mark Hachman / IDG

Cinebench R23, a more advanced version of the benchmark, offers a way to check whether thermal issues are at fault: run a single test, then loop the test over and over for ten minutes and compare the results. But the scores were comparable—2,895 versus 2,867—which led me to doubt whether that was the case.

We saw more anomalies in the Handbrake test, which uses a free tool to transcode video into a format formatted for an Android tablet. It’s a real-world application, though less so in a world where Netflix movies can be saved to a laptop. We measure the time Handbrake takes to complete the task as a way to determine both the performance of the tablet as well as its ability to keep cool over a long period of time. As before, I ran several tests, cooling the tablet down and not running them back to back. Performance began at 2,773 seconds, then to 3,191 seconds, and then several runs of 4,300 seconds or so. As with the Cinebench test, it’s difficult to say what the “true” performance of the tablet is, including whether some software or firmware glitch is limiting the Surface Pro 8’s true potential.

In graphics, though, the Surface Pro 8 delivered consistent results. Here, we used the 3DMark Time Spy test, and the Iris Xe GPU performed excellently.

Finally, we tested battery life. Battery life is becoming increasingly more challenging to test, as more laptop manufacturers add sensors that detect the ambient brightness of the screen and adjust the output accordingly. (Smartphones do this regularly.) The wrinkles that the Surface Pro 8 adds to this are threefold. Microsoft and Windows will adjust the “content” of video being played back, to preserve battery life; adjusting the display refresh rate will affect battery life, too. Finally, our Surface Pro 8 review unit decided after a few days to implement “smart charging,” a new feature that prevents the battery from being charged past 80 percent. That’s great—if there was a control to turn it off. We couldn’t find one.

All this means that there were simply too many variables to present you with a comprehensive picture of how long the Surface Pro 8’s battery will last. We typically run down a laptop battery by looping a 4K video over and over until it expires, and we did that here. What we have are a pair of rundown tests where we disabled the lighting sensor (though not the content adjustment) to provide a repeatable though worst-case scenario. It’s not fantastic, but at 8 hours 49 minutes you should get a full workday’s use out of it. We recorded scores of 610 minutes and 447 minutes on a full charge, which we’ve averaged to generate a score. Dialing up the refresh rate to 120Hz didn’t seem to actually lower the battery life at all, as the tablet expired after 628 minutes.

Mark Hachman / IDG

Turning off both the lighting and content adjustment capabilities on the Surface Pro 8 delivered an awful battery life of 375 minutes, or 6 hours 15 minutes. That’s at a 60Hz refresh rate, too. That’s not the default configuration, however, and you would need to adjust the tablet’s settings within the Settings menu to achieve that score.

All of the variables present a problem. The wonky numbers Microsoft’s Surface Pro 8 generated makes us suspicious that there’s something else going on: some interaction with Windows 11, early firmware/drivers going haywire, something. If it’s not a deeper issue, Microsoft should eventually deliver drivers that allow us to present a more confident assessment of the Surface Pro 8’s capabilities. But right now, its performance and battery life still remains somewhat of an open question.

Conclusion

All of this presents a question: how well do we know the Surface Pro 8? From a hardware perspective, quite well: we can certainly see the value of the larger, superior display, and the tablet’s audio sounds great, too. Sure, the webcam appears to need a little work, but that’s a tweak it should be able to implement quickly.

The question that we can’t answer is whether or not we’re seeing a discrepancy in our particular benchmark software, or a driver issue, or Windows 11. Is the performance and battery life really this bad? We suspect not, but we can’t say that for certain, either. We love what Microsoft has set out to do with the Surface Pro 8, but we’d be remiss if we recommended the tablet based on our findings right now.
