coudlnt quite find a current thread on this, so here we go...

We have currently a HP Z600 dual processor we can remotely log into to run 'complex' ( few hours, and +) simulations in SW.

The he machine is getting old and I'm sure there is much more power available these days for a few thousands $.

if today you have to built a machine dedicated to SW simulation, what would you pick? Factorise cores? RAM? SSD and bus speed?? Is multi processors still relevant, or is a single recent CPU well enough?

what would your dream machine be like?

(trying to built a case for IT to get us something newer here...)

No one else has this question

Currently Im Planning to build a PC since my machine is getting old this what im thinking

Processor: INTEL XEON E5-2696v3 / E5-2699v3 SR1XK - 18-CORE 2.3GHz - 45MB Cache - Socket R3 (LGA2011-3)
Motherboard: ASRock X99 OC FORMULA LGA2011-v3/ Intel X99/ DDR4/ Quad CrossFireX & Quad SLI/ SATA3&USB3.0/ M.2/ A&2GbE/ EATX
Ram: 64gb memory for starting but can be upgrade to 128GB memory in the future
Graphics Card: 12gb Nvidia quadro M5000

Look into the HP Z840, you can build it up to about $30k and it will work for many years. Dual Xenons, DDR4 RAM & DDR5 on video card w/ good processor. Make sure boot and data drives are SSDs, 1T each.

  Just make sure you verify w/ SW for acceptable hardware/sw before you buy.

Call up the guys at Boxx (www.boxxtech.com) They helped us with our workstations by talking to us on the phone for a while and figuring out what our needs were. Plus they have followed up 2-3 times in the last 6 months just to see how they were running.

You can find some general information and guidance on "baseline" SOLIDWORKS Simulation hardware recommendations in the following SOLIDWORKS Support Monthly News blog post:

Some Interesting results here from puget systems (i don't have any connection to them!)

https://www.pugetsystems.com/labs/articles/Solidworks-2016-Multi-Core-Performance-741/

Seems that a single CPU may be a better bet than Dual processors if it is just Simulation you are using it for. As others have said the key is to keep the CPU speed high and not sacrifice that for more cores. typically 6-8 at 3.6 or 3.5Ghz e5 Xeon v4 (or higher if you with i7 overclocked systems) is the sweet point for cost vs performance but if you have the budget then more may be worthwhile for some situations. SSD is best as swapping alot of data in and out of RAM and a larger CPU cache seems to have some benefit for similar reasons.

  hmmm this is something cought me up why is that higher clock speed is better than more core, simulation is a system monster

    yeah that got my attention also... so a 8 core CPU at 3.0GHz would be better that a 12 or 14 at 2.4GHz?

      I did some research since i will be building My computer dedicated for simulation, rendering, solidworks, will of course gaming i always seen that they always say that more core is better, in the benchmark shared by Alan Sweetenham which is this, https://www.pugetsystems.com/labs/articles/Solidworks-2016-Multi-Core-Performance-741/ they use dual processor with 20 core but how about using single processor with 18 core i'm interested if there will somebody share some bench mark.
