    Phoronix: Windows 10 Competing Well Against Ubuntu 20.10 On The AMD Ryzen 9 5950X

    Earlier this month we were a bit surprised to see Windows 10 performing close to Ubuntu 20.10 on the AMD Ryzen 9 5900X. With prior AMD Ryzen (and Intel Core) desktop CPUs we normally are used to seeing Ubuntu Linux exhibit healthy performance advantages over Windows 10 in most workloads. But with Zen 3 the Windows vs. Linux performance is much closer and thus led us to also running Windows 10 vs. Ubuntu benchmarks on the higher-end Ryzen 9 5950X to reproduce the earlier findings.

    What was the issue with amdgpu? Btw THX for the benchmark

      I wonder if lack of IFUNC (function specialization for specific architectures) on Windows is hampering some of the tests.

      And to be clear, it's a real issue.

        Interesting how Win10 is always faster on basic 1080p AV1 encoding but slower for all the heavier AV1 tests on both big Ryzen CPUs
