ryzen on 3d cad

I just like to get some user feed back if anyone has used Ryzen 7 1700, 1700X or 1800X for 3D CAD like Inventor, SolidWorks, Solid Edge or Geomagic/Alibre. Currently I am using a Ryzen 7 1700 on IRONCAD coming of  from an FX8370. My experience has been positive as it was a large improvement of the past CPU. In terms of 3D modeling with under 3000 parts and using a RX 470 4GDR5 GPU, 32 GB DDR4 RAM, ASROCK B350, it is still fine, with creating 3D models with no issues and display lag on rotation will be at the GPU's delivery. As the 3D model is displayed on the associative 2D drawing module, I have done 50 sheets plus on a single file still works but starts to be a bit sluggish.  To alleviate the situation, set the windows power options to High Performance, but of course higher cpu clock matters.


On a minimum processor state settings of:

36% took 65 secs. to save 57 MB drawing file

72% took 54 secs. to save the same file.

The 3D model file itself is 64 MB


My initial CPU was the 1700X but the funds didn't come on time that I have to settle for the 1700. As the price of the 1700X has come down, I am planning to to upgrade to the 1700X , if lucky to the 1800X to get the higher base and single thread clock


My point is I don't want to overclock any of the CPU since I am after stability, so the 3195 all core boost and single thread boost of 3750 for the 1700 will be improve as much 3500+ all core boost and single thread 3800+ for the 1700X will be a welcomed benefit. Also overclocking disables power saving features.


So far I haven't seen any user feed back. A video from TFI compares it with i7 HEDT on merit of the quad channel and workstation class gpu, but that is beyond on my budget allows and the size of work I do.


As for rendering with KeyShot, 123.8 FPS is fine on the 1700 given it's a 65W CPU.


I appreciate users views on this one. Thanks for sharing.
