I am working on specs for a new workstation and wanted to get some insights on processor differences. I have read through the discussions on system recommendations and think I have a pretty good understanding of what I need for most of all the components. However, I have a hard time keeping track of all the processor variations and could use some reassurance I am on the right track.
I am looking at going with a HP Z620 with a Xeon E5-1650 processor (3.2Ghz, 12MB, 1600, 6 Core). I do a bit of everything in Solidworks; large assemblies, large assembly drawings, FEA on small parts, and Flow Simulation. I am looking for something that will work well for both modeling, drawings, and Flow Simulation, so it seems I need a balance of speed and cores. The E5-1650 seems like it might do the trick. As I have looked at the higher end workstations, I am wondering what benefits the E5-2640 or 2643 may have over the E5-1650. There is a huge price difference, so I would like to understand better what performance comes with it.
Thanks for the help, and apologies if I have missed an existing discussion that may answer this question.
PS I attached an Intel comparison for reference
