    Is there a reason why the 7800X3D beats the 7950X3D when it’s meant to be clocked lower? Is it a scheduling issue or something where the wrong cores are used? If CCX1 was disabled would the 7950X3D then become consistently better?

      The early reviews showed the 7800X3D a little faster than the 7950X3D, but the scheduling has been improved since then. The 7950X3D is faster for gaming in most cases now, because of the slightly higher turbo.

        Nothing has changed about 7950X3D scheduling since launch.

        It’s just a matter of how many games are included in the average where the gamebar parking doesn’t work.

          It also depends on whether they’re evaluating games that use more than 8 cores. The 2 CCD latency penalty is probably a little bit overblown because even in the previous generations, 5950X/5900X beat the 5800X in quite a few games.

      The reason why the Ryzen 7 7800X3D is able to perform as well as the flagship comes down to the fact that it uses a single core complex (CCX). That leads to faster cache-to-cache transfers, according to AMD, helping the Ryzen 7 close the gap in gaming performance compared to the dual CCX Ryzen 9 7950X3D

      Is it a scheduling issue or something

      Yes. Hence the Intel’s release of a scheduling driver for 14th gen.
