Windows 10 Competing Well Against Ubuntu 20.10 On The AMD Ryzen 9 5950X
While not a focus for the comparison, some Vulkan-based tests were run for seeing the Windows vs. Linux performance with Radeon Software's latest build against that of Ubuntu 20.10 with RADV for the Radeon RX 5700 XT graphics.
RADV generally came out comparable or slightly ahead of the Radeon Windows Vulkan driver performance.
One of the areas where Windows 10 has long performed better than Linux has been with the Mozilla Firefox web browser performance. Firefox 84.0 was still favoring Windows 10 on this AMD Radeon RX 5700 XT + Ryzen 9 5950X system compared to the Firefox Linux performance.
Google Chrome in some past comparisons has also seen an advantage on Windows but with Chrome 87 on the two operating systems the result across multiple benchmarks were very close.
