A development build of Windows 11 leaked online this month ahead of Microsoft's big Windows press event on June 24.

While we won't know for sure until the full product is released and we test it ourselves, some recent benchmark tests conducted by the folks at Hot Hardware suggest that PCs running Windows 11 will perform better than PCs running the latest version of Windows 10 suggest that they will perform better than PCs running the latest version of Windows 10.

Specifically, Hot Hardware took an Intel Core i5-L16G7-powered Galaxy Book S laptop (one of Intel's Lakefield hybrid chips, a pair of high-performance and high-efficiency cores) and ran several CPU benchmarks We ran some CPU benchmarks.

Despite the unfinished nature of the leaked build, the Galaxy Book S running Windows 11 performed as well as or better than the latest version of Windows 10 on nearly all benchmarks.

Most notably, these tests suggest that Windows 11 may have some under-the-hood improvements that will increase browser speed, at least on Intel's hybrid Lakefield CPUs, such as Angular and In a series of custom tests measuring the speed of Chrome running a series of sample projects written in real-world JavaScript frameworks like React, the Galaxy Book S ran more than 10% faster while running Windows 11.

The good news is the fact that even unfinished builds of the next generation of Windows show a slight improvement in CPU performance over Windows 10. We'll have to wait and see if such improvements are present in the final build, and whether they show up equally clearly on non-hybrid CPUs, as Windows 11 has its roots in a mobile-focused, touch-friendly variant of Windows 10X, may be the reason why the Galaxy Book S and its Core i5 Lakefield CPU can be utilized better than Windows 10.
