Windows 11 has had a rocky time keeping up with Linux in terms of performance in the last few months.
While Intel and Intel were able to build 12th Gen Alder Lake CPUs that were based on the Performance Hybrid architecture, including big E-cores and bigger P-cores, the story was quite different back in 2021. As such, the Intel Core i9-12900K was found to perform significantly better on Windows 11 than Linux. Kernel version 5.16 was also found to be not quite quite ready for the new design, as it was also handily beaten by Windows 11.
Even though the performance gaps had been significantly reduced, things are starting to change. Tests back in July found Linux was no longer trailing Windows 11. The comparison was conducted using a portable Alder Lake Core i7-1280P CPU, and Microsoft was still ahead of Windows 11. However, patches have revealed that further improvements are being made on Linux for hybrid x86 processors like Alder Lake and its future Intel architectures.
While comparisons on AMD and Ubuntu have found that Windows 11 and Ubuntu are narrower, as the two operating systems are seen trading blows.
Phoronix completed a follow-up test using an eight core Ryzen 7 5800X3D, which is AMD''s first processor with 3D V-cache on-board. Windows users would not like the results. Ubuntu 22.04.1 has won 81 or 91% of the tests, but Windows 11 has won only 9% or 8 tests.
The greatest performance differences are seen in the Renaissance benchmark Instance Metadata Service (IMDS) test followed by DaCapo Tradesoap. Interestingly, Windows 11 is higher than Tradebeans, though by a significantly smaller margin. Overall, the Geometric Mean indicates that Ubuntu was about 10% faster on average, despite that there were currently 90 tests in this comparison.
It will be interesting to see how the performance on a non-X3D chip like the Ryzen 7 5800X, or how the two OS would perform in a comparison using the upcoming Zen 4-based Ryzen 7000 series chips. According to reports, the Zen4X3D SKUs aren''t too far off either.
