Hello,
I'm evaluating 2 options for a home CFD workstation for similar prices (I've found good deals for about $1,600-$1,700):
CPU: 2x Intel Xeon E5-2680 V3 (2.5-3.3GHz) -12C RAM: 64GB DDR4 RAM HDD: 240GB SSD & 1TB SATA HDD (Data Drive)
OR
CPU: 2x Intel Xeon E5-2667 V3 (3.2-3.6GHz) - 8C RAM: 64GB DDR4 RAM HDD: 512GB SSD
The first option seems to be a better choice but is it really? My question relates mainly with the balance between having more cores but worst CPU clock speed. How would this affect performance and how to find a balance?
PS: Would you recommend any alternatives to the ones above?
Thanks
Hello, Mr. Filipe. to balance which cpu to use with the best cost benefit.
the first one takes into account the minimum requirements that the software you use requires,
second how many cors can the software work with?
Third which video card the software can work with.
Thanks for the reply André. The software is open foam (the most cpu intensive at least).So I believe there is no limit in terms of parallel licensing.
From the given information I would tend to the workstation with the higher number of cores as well. But an exact measure on how cores and clock speed will counter-balance each other could only be derived from a benchmark case being run on both types of workstations in direct comparison. Other factors like memory bus speed, clock rate of memory subsystem, etc. play a role as well.
Regards,
Dr. Th. Frank.
