   I was recently able to get a workload of mine optimized enough on Zen 5 to hit a sustained 6.0 IPC/core (3.0 / thread) at 5.1 GHz. Seeing the a > 99.8% branch prediction rate and a > 99.99% L2 cache hit rate retiring > 1T instructions every 3 seconds feels amazing.

   Zen5 is incredible when you're able to make the most of it. I’m super excited about Zen6.

      zen5 is really the first CPU of the avx512 era (since it's the first time normal compiler devs have them to play with)

         We had Ice Lake and Rocket Lake too, they seem to have disappeared from the collective memory

            And nobody talks about the Xeon Phi anymore…
