Disable boost, and run this benchmark: http://www.overclock.net/forum/newestpost/1392721
at the same frequency with both CPUs. (You must run pac4C.cmd,, then pack8C.cmd. Or disable hyperthreading and run only pack4C.cmd)
It outputs results in: time in ns followed by a hash. Lower number is better of course. You can compare results to AMD results from that thread. (Intel should be better per cycle in this benchmark however.)

Yes Intel is cheating. It doesn't have power to run AVX2 on normal voltage, thus they up the voltage, and hope user will not use AVX2 long enough to cause degradation. Of course upping voltage of an overclocked overvolted CPU is suicide.Edited by Raghar - 6/3/13 at 7:48pm
