AMD Ryzen 7 7840U Windows 11 vs. Linux CPU Performance

Overall this Windows 11 vs. Linux comparison on the Acer Swift Edge 16 with AMD Ryzen 7 7840U was an interesting comparison as typically Linux comes out on a notably stronger footing.

Out of 75 tests ran in total across the four OS configurations, Windows 11 Home was the fastest 26% of the time, Ubuntu 22.04 LTS with Linux 6.2 was in first place most often (55%) while Linux 6.5 Git did slow down in some areas with the switch to the AMD P-State EPP driver for better power efficiency and the AMD Inception mitigation lowered the performance in some areas.

When taking the geometric mean of all 75 benchmarks, Ubuntu 22.04 LTS was faster by about 13% but that narrowed to 4% when running stock Linux 6.5 with the default CPU security mitigations. Across that span of benchmarks, the AMD Inception mitigation lowered the performance by about 5% while the other Linux 6.2 to 6.5 kernel differences represented the rest.

Those wishing to go through all 75 tests in full can find the data here including CPU power consumption data on the Linux runs for those wanting to look at the power efficiency too with the kernel differences.
