Windows 11 early benchmarks reveal possible performance boost
A developer build of Windows 11 leaked online this month ahead of Microsoft’s big June 24 Windows press event, and thanks to some independent testing of that build, we have reason to believe the next version of Windows could deliver a notable performance boost for some PCs.
Though we won’t know for sure until the full product launches and we can test it for ourselves, some recent benchmark tests run by the folks at Hot Hardware suggest that you can get better performance out of a PC running Windows 11 than one running the latest version of Windows 10.
Specifically, Hot Hardware took a Galaxy Book S laptop packing an Intel Core i5-L16G7 CPU — one of Intel’s Lakefield hybrid chips, which pair high-performance cores with high-efficiency cores — and ran it through some CPU benchmarks, first using the latest build of Windows 10 (Windows 10 21H1) and then using the recently-leaked developer build of Windows 11.
The results are promising: even though the leaked build is unfinished, in just about every benchmark the Galaxy Book S running Windows 11 performed as well as or better than it did running the latest version of Windows 10.
Most notably, these tests suggest Windows 11 may have some under-the-hood improvements that boost browser speed, at least on Intel’s hybrid Lakefield CPUs: in a set of custom tests that measure how fast Chrome can execute a series of sample projects written in real-world JavaScript frameworks like Angular and React, the Galaxy Book S performed over 10% faster while running Windows 11.
