Workstation build thoughts

[BB_PSS]

Hello all,

I'm looking at a build and hoping to get some feedback on hardware:

Processor: AMD Ryzen 9 3950X (16-Core) 4.7 GHz Turbo

System Memory: 64GB DDR4 3200MHz

Graphics Card(s): 1x PNY Quadro RTX 4000

I'm currently running Creo 4.0 and get bogged down having a large assembly open.

Processor clock speed is more important than than overall speed.  Creo only uses one thread and 16-cores is not much better than 4-cores.

Memory should be fine.

Graphics card is not  certified or supported.  Look here for the official PTC list:

I chose the Ryzen because it had higher single thread speed (2,746 MOps/Sec) than my current which is around 2,000 MOps/Sec

Although the PNY card is not certified or supported the Nvidia same model is certified so it was sort of an assumption that I'd be alright there

Core Creo Parametric features run on a single core. Select a CPU with the highest single thread performance you can afford to max Creo modeling performance. Generally this is the fastest base clock speed you can get.  Many cores do nothing to speed up model regeneration.

For RAM and GPU you should benchmark your large assembly on the hardware of interest (if you can) to see if it makes a difference. The GPUs are oversold by the vendors and I have found that unless you are using them for rendering or ray tracing on CAD models you can use a less than top of the line card for Creo modeling with no performance hit.

If you are running simulation that can use the GPU then that will be the driving consideration.

As both other replies have mentioned, single core clock speed is critical.  Some assembly tasks will leverage multiple cores, but for the most part Creo is still very much single threaded.  This is why overclocking the CPU is so helpful.  Get the fastest clock speed you can afford, and then pair that with a fast SSD and decent graphics card.  😉

Just curious, what is your current hardware specs? Are you running out of RAM when you are loading your large assembly?

Are you using large assembly management techniques such as simplified reps to help manage your large assembly memory usage? Are you doing drawings of your large assemblies? 

I just want to make sure you aren't going to be disappointed in your new computer when it doesn't perform 10x faster than your current setup.

I'm currently on a Dell Precision 7710 with Xeon E3-1505M and 32 gb ram. i cant complain too much for the price and how long it has lasted.

I typically look at the benchmark to help with new computer component selection but we are limited by our IT group who we can buy from so it tends to be Dell Precision workstations, fastest processor, good Quadro video, reasonable RAM, I think I have only tapped out my 32gb a few times but I work to keep my simplified reps clean so I don't load to much, until it comes time for weights and CG. But I never do those calcs with a drawing open, only the model. I could probably benefit a little with 64Gb ram but it wouldn't help on a day to day basis. I don' t do any FEA or such, only creo design and drawings.

The top ones on the benchmark are usually custom built and tuned computers to maximize Creo performance.
