1x Zeon Silver 4108 or 2x E5-2690 v2
 

Hi,


Im just to get a work station for using Ansys CFD software.

I'll admit to being pretty knowledge limited when it comes to system hardware details.

I was therefore wonder if it would be better to buy a brand new HP Z8 with a single Xeon Silver 4108 CPU at 1.8Ghz (64GB RAM), or a HP Z820 Dual Xeon E5-2690 v2 station at 3.0Ghz (128 GB RAM)


Appriciate any feedback and help that can be offered


Thanks

How many parallel licenses do you have?
The Xeon silver machine would need to be reconfigured. In order to use its 6 memory channels, it needs 6 or 12 identical DIMMs. So either 48GB, 96GB or 192GB of RAM.
But even then, the older dual-socket workstation would be faster if you can use all cores. Be aware that many resellers equip this kind of machines with cheap and slow memory. So before buying, make sure it uses DDR3-1866 memory.
