lifeinhand New Member Han Li Join Date: Jul 2015 Location: College Station Posts: 16 Rep Power: 10	I am curious about the performance for CFD performance between these two CPUs for some not too big cases (cell number under 1 million). E5-2660, 8 Cores 16 Threads, Base Frequency 2.2Ghz; Max frequency (Using all Cores) 2.7Ghz. E5-2667, 6 Cores 12 Threads, Base Frequency 2.9Ghz; Max frequency (Using all Cores) 3.2Ghz. E5-2660 may seem better because of more cores, but parallel performance in CFD is unlikely to achieve 100% speedup. So I am curious which will perform better in CFD computation?
