    Affected CPUs: AVX-512 capable CPUs. Intel Xeon, Zen 4 AMD Ryzen and EPYC and up.
    Affected function: UYVY to YUV422 format conversion (pixel-level color encoding).
    Speedup: 18/10.98 = 1.64x (Since all AVX512 cpus should support and previously have used avx2(56)).

    Apparently as part of an ongoing series of rewrites, they made a color encoding conversion function run 64% faster on server CPUs and somewhat recent AMD CPUs

      I wanted to read about double pump but the linked article looks like a general benchmark, without an explanation of that concept?
