Comment on FFmpeg devs boast of up to 94x performance boost after implementing handwritten AVX-512 assembly code

  Then this is your reminder that ALL AMD CPUs are Unlocked and support overclocking…

    True, though it’s worth noting that AMD focus efficiency means that there isn’t a lot of extra performance you can get from their modern CPUs with overclocking.

      I think it’s less because of their efficiency focus and more because the chips already auto-overclock to reasonably high levels.

        I meant more of the whole approach of designing chips with efficiency as a top priority which means they get the best performance they can within their efficiency targets, which is always more optimal than users tinkering on their own. Efficiency and performance are kind of different sides of the same coin.

      Yeah, but Intel charges you $200 more for the -K sku so you can find out the same applies to Intel :)

  Probably some BS market segmentation move.

  I imagine they noticed only certain server customers were using those extensions, so decided to limit them to high margin server SKUs.

  It would have been a smart move if there weren’t competitors putting that instruction in every CPU.
