Microsoft is set to announce Windows 11 next week, and in case you missed it, a build of the new OS leaked this week.

Now, one user is citing some big Windows 11 performance improvements over Windows 10.

It comes from YouTuber Ben Anonymous, who’s claiming to be using an official build of Windows 11.

It’s clearly different though, as he shows off some features that aren’t in the leaked build.

For Geekbench, the single-core performance increased from 1,138 on Windows 10 to 1,251 on Windows 11, and the multi-core score increased from 6,284 to 7,444, so there are some impressive improvements there too.

We’ve been running performance benchmarks since the build leaked earlier this week and haven’t been able to replicate this, although as Ben Anonymous notes, he’s running a different build of Windows 11.

Microsoft is absolutely going to talk about performance when it announces Windows 11, and once we all get a real preview, we can start running out own tests?
