Default CPU:Intel 3.0E or 3.0C

Hi, all

I want to buy a PC with Intel CPU 3.0GHZ for CFX modelling in this month. Initially I choose Intel 3.0E because it has 1M cache. But a friend said 3.0 E has big problem in cooling if I want to run the program for a long time...

If anyone is using Intel CPU 3.0 E, could you please give some suggestions? I am also intertested in the comparison between Intel 3.0 E and 3.0 C for CFX cumputation. I may change to 3.0 C if no great difference between the two versions .

Thanks!

Andrew

Hi Andrew,

I don't know the difference between the two, except that the larger cache shows some speed increase on the spec website (www.spec.org). I don't know if that maps across to faster CFX runs.

I do know that hyperthreading actually slows CFX runs down. CFX does not support hyperthreading, so if you have a chip with hyperthreading you will run faster if you disable it. (BTW: I understand you can disable it in the bios.)

Regards, Glenn
