    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.

          With your CPU you should be more than sufficient and as you mentioned higher core clocks in this case do matter. Other things to look at especially when dealing with larger files on AutoCad are your memory and storage. For best performance, you'll want the fastest most stable setting on your memory, while also having fast R/W speeds available on your storage. Get at least an improvement on your memory in this case, and you'll see an overall boost. For AutoCad (if you care about the surface rendering), you'll want to get the best GPU you can get for performance, especially when rendering in a 3D scope (+ effects etc) - this is when you enter the realm of Pro (both GPU/CPU). For now, based on the numbers you posted, you're really not in a bad position until you can look into future upgrades.


          KeyShot - on a stock 1800X, 32GB Ram @ 3200MHz, Rx 480's (8GB).


          PS, the KeyShot numbers below are from the camera benchmark while OBS was recording at 4K resolutions (CPU intensive); avg FPS during the benchmark increase by about 20FPS without OBS running. I getting about 60FPS more on a single Vega FE card, but have some unresolved driver and memory downscaling issues ATM.

              Thanks for sharing. Hmm, now I am in between thinking of either a Radeon Pro WX4100 or R7 1700X. My ram is set to run at 2933, initally I was able to set it up to 3066 from the AGESA update. Using the G.Skill  RipjawsV 16x2 GVK3000

                Thanks whiskey-foxtrot. I just got the Ryen 7 1700X, an it runs a lot better as it clocks 3492 MHz all cores and 3891 Mhz on turbo boost single core on standard cpu clock settings. The 1700X and 1800X excels in 2D-3D CAD and 1600X on a budget if you don't want to mess with overclocking. The 1700 is great for low power consumption 3D rendering. ASROCKB350 reports the correct temperature so no need to set on your mind the 20 degrees differential.
