Windows 11 performance beats Windows 10 by a mile

Time to analyze some benchmarks.

What you need to know

• Windows 11 leaked ahead of its official announcement on June 24.
• Since then, users have been poking around to see how it differs from Windows 10.
• A person claiming to have an official copy of Windows 11 (not the leak) has shared performance benchmarks.

In case you didn't want to wait for Microsoft to unveil it on June 24, here's the scoop: Windows 11 is out in the wild via a leaked build. However, one Youtuber is claiming to have an official copy of the operating system from Microsoft. His video breaks down the interesting performance differences between Windows 10 and its new successor.

If the information in Ben Anonymous' video is accurate, Windows 11 isn't just a visual shakeup of the Windows we all know and (at least some of us) love — it also sports better performance than W10.

It's a rather long video that goes into the nitty-gritty on a whole bunch of items, ranging from 3DMark and Geekbench 5 results to basic boot speed comparisons. Luckily, Ben Anonymous was kind enough to include timestamps in his video, so you can cut right to the end if you just want the juicy faceoff content. Here are the highlights.

Windows 11 Pro Build 21996.1 booted 18.75% faster than Windows 10 Pro Build 19043 (13 seconds versus 16 seconds).

Windows 10 got a 3DMark score of 6,872 at 4.8GHz, hitting 92 degrees celsius on the CPU while reaching 76 degrees celsius on the GPU. Windows 11 got a score of 7,613 at 4.9 GHz. It hit 99 degrees celsius on the CPU, 78 degrees celsius on the GPU. That tallies out to a 9.74% better 3DMark score and 2.05% better clock speed, albeit at the cost of a 7.08% hotter CPU.

CrystalDiskMark, which measures SSD speed, gave these results:

• Windows 10: Read speed of 2,930 MB/s, write speed of 3,189 MB/s
• Windows 11: Read speed of 3,448 MB/s, write speed of 3,336 MB/s

Those results illustrate a 15.03% faster read speed and 4.41% faster write speed on Windows 11.

And here's what BenAnonymous got during his Geekbench 5 testing:

• Windows 10 managed a single-core score of 1,138, a multi-core score of 6,284, at 4.8GHz at 97 degrees celsius on its CPU
• Windows 11 boasts a single-core score of 1,251, a multi-core score of 7,444, at 4.9GHz at 93 degrees celsius on its CPU

That equals 9.04% better single-core performance and 15.59% better multi-core performance at a 2.05% faster CPU clock speed while running at a 4.13% cooler CPU temperature.

How Windows 11 is pulling off numbers this much better than Windows 10 is anyone's guess at the moment, but if said numbers are accurate, a lot of people are in for a nice little performance bump.
