We’ve heard a lot about Microsoft’s new Copilot+ PCs over the past few days, but we can finally put some hard data to the company’s bold claims. Signal65, a benchmarking and analysis company, put the new Surface Laptop through its paces, and it absolutely wrecks the MacBook Air M3.

The laptop, equipped with a Snapdragon X Elite processor, put up impressive results across the board, but battery life stands out most. According to the report, the Surface Laptop lasted over 21 hours in a local video playback test. For reference, that’s close to twice as long as the Surface Pro 9, and more than 15% longer than the MacBook Air M3.

In raw performance, the MacBook Air M3 won out in single-core performance in both Cinebench and Geekbench by around 15%. However, in multi-core performance, the Surface Laptop was upwards of 30% faster than the M3. Even more impressive, the Snapdragon X Elite was more than twice as fast as 12th-gen Intel Core i7 chip, and around 5% faster than Intel’s latest Core Ultra 7 155H.

You can download the full report from Signal65 if you want to dig into the numbers, but there are plenty of interesting comparisons. In a video encode through Handbrake, for example, the Snapdragon X Elite beat the Apple M3 by close to 25%.

It’s important to point out that this isn’t a review of a Copilot+ PC, though. The report was compiled by Ryan Shrout, an ex-Intel employee who’s now a part of Signal65, and it was commissioned by Microsoft. Companies like Microsoft will often hire a third-party analysis lab for this sort of performance validation to substantiate its performance claims. That isn’t to say that the report is inaccurate, but just that a wider swath of reviews can target more areas of performance.

Although the report was commissioned by Microsoft, it’s not just gassing the Surface Laptop up. One section that’s particularly interesting concerns emulated performance. Here, Shrout tested apps running through Microsoft’s new Prism emulation layer against laptops running the same apps natively, and the Surface Laptop doesn’t always win.

In Blender, for example, the Intel Core Ultra 7 155H was around 46% faster, while the Apple M3 was 17% faster. On the flip side, the Snapdragon X Elite managed to match the performance of the Core Ultra 7 155H in Lightroom Classic, despite the Intel chip running a native version of the app.

Prism is a key factor in Copilot+ PCs, as it will serve as the bedrock for apps like Lightroom and Blender that don’t natively run on the Snapdragon X Elite at this point. Although you’re not getting native performance, this report at least shows that Prism is doing a lot of work, and it’ll hopefully get better with time.

We don’t have to wait long until we see more independent reviews of Copilot+ PCs. The first crop is available for preorder now, and they’ll release on June 18. By then, we’ll know if these PCs are really as powerful as this report suggests.

4 high-end features Windows laptops still have over MacBooks

Lenovo Yoga 9i Gen 9 top down view showing tablet and pen.

Apple’s MacBook lineup has exploded over the last several years, with its Silicon chipsets offering class-leading performance and efficiency. The MacBook Pro, in particular, is faster than many Windows laptops, longer-lasting than most, and has an excellent mini-LED display. There are many good reasons to choose a MacBook over a Windows laptop in today’s market.

But all isn’t lost for the Windows platform. Even aside from the upcoming Snapdragon X Elite laptops that look to be competitive, there are still some more basic features that you can only get on a Windows laptop at the moment. Here are the four that I keep coming back to.

Why Samsung’s answer to the MacBook Pro can’t quite compete

The Galaxy Book4 Ultra open on a wooden suruface.

The 16-inch MacBook Pro is the king of the creator laptops, and it’s been that way for several years.

But there have been a wave of new Windows laptops attempting to challenge the MacBook Pro on its own terms. The Samsung Galaxy Book4 Ultra is certainly a contender, packing some impressive specs in a portable chassis. When you compare the two straight up, the MacBook Pro 16-inch clearly comes away with the upper hand, even when considering its higher price.

The XPS 16 is fighting an uphill battle against the MacBook Pro

Dell XPS 16 sitting on desktop with flowers.

It took a few years, but Dell finally updated the design of its two largest XPS laptops. The XPS 15 gave way to the XPS 14, while the XPS 17 was replaced by the XPS 16. The latter gained the ultramodern look of the XPS 13 Plus, complete with a glass palm rest, a hidden haptic touchpad, and a row of LED function keys.

It’s a significant update but places the XPS 16 in direct competition with the Apple MacBook Pro 16. That’s an excellent matchup with proven performance and battery life and an elegant design that’s solid, if a lot more conservative.
