I just started up my new computer Windows 7, 3.6 and 8 core versus the older one which is also Windows 7, but 3.2, and 6 core. My Einstein units take longer on the more powerful computer by about 40 minutes each. I have a GTX 580 and the cuda units crunch much faster than on the older one with a GTX 460. That I understand, but I am puzzled by the cores running slower. Does anyone have an answer?
