Why is the 7800X3D so much faster in that benchmark than 7950X3D? The 7950X3D seems to boost on paper to even higher frequency. Is the cache different per core?

- MindSpunk 3y ago7950X3D only has the 3D stacked cache on one of the two chiplets, so as far as gaming is concerned you only want to use 8 of the 16 cores. 7800X3D would boost harder for gaming because the 7950X3D has a second vestigial (as far as gaming is concerned) chiplet that eats power that could be better spent in the v-cache enabled die.

- kllrnohj 3y agoFactorio didn't get detected as a game properly so it was half on the vcache cores and half not on it. It's kinda heterogenous compute, and schedulers aren't that smart about it (at least Windows' isn't). If you set affinity to just the 8 cores with vcache then the 7950x3d matches the 7800x3d
