Prefetching disabled:
5820K has two prefetch settings in BIOS, one is Hardware Prefetch and second, Adjacent Cache-Line Prefetch. I disabled both for lolz just to see how it goes.
Single thread performance was consistently higher by ~50 points where multithreaded hardly ever changed much. 20 is about as much difference I ever got. And that's from 12 threads combined. 50 jump is just for single thread. Only thing that changed between both runs are the cache settings, no fiddling with clocks or other settings.
I just find this interesting...
