Exercise some caution around all of these leaks.
Update: Upon further review, it appears the benchmark results presented in the video are inaccurate. The tests performed on Windows 10 were done with the “Recommended” performance mode, while the Windows 11 tests were done on “High Performance.” This explains the disparity in scores. While it appears there might be performance improvements coming with Windows 11, the benchmarks in this article are not an accurate representation of that. The original story has been updated to reflect these changes.
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. One Youtuber, Ben Anonymous, has performed benchmarks comparing Windows 10 and Windows 11, but a disparity in performance modes makes the data a wash in regards to any perceived improvements
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. However, it later came out that the Windows 10 tests were performed in the “Recommended” performance mode while Windows 11 was in “High Performance” mode. That makes any comparison virtually worthless, but the tests are still interesting because they’re some of the first we’ve seen with Windows 11.
Here are some of 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.
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
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
While comparisons based on this video can’t be done because of the performance mode disparity, it still appears we’ll see some improvements with Windows 11. Hot Hardware recently performed some comparison benchmarks that allude to this. However, it’s worth noting that all of these tests are being done on a leaked build, and we don’t know how old it is. In other words, take anything you see out of this build with a massive grain of salt.
