In this case, the clock speed difference is so great that the 8 core outperforms the 12 core in all settings, but especially more at 32 samples. I am running the 8 core at 4.3Ghz, liquid cooled, but you cannot overclock the Xeons, so the 12 core is limited to 2.7GHz.
That’s why I just built an 8 core 5960X i7 instead of a 12 core Xeon (PC of course). RdRm is correct, clock speed matters a lot for low latency.
