Posted February 2, 2020 Hello! I'm going to build a new computer, and since I mostly need CPU and RAM for now, I'm going with the ryzen 3950x with 32Gb of RAM but i'm keeping my old 970 strix OC (Can't buy everything at once for now, i'll wait for what 2020 brings as far as GPUs). I don't know much about this, as you can probably tell, but, will this have any impact in the performance of this new build? Will the old 970 hold the performance of the 3950x down? I don't even know if this makes sense but oh well. Keep in mind this is not supposed to be a gaming pc, but a workstation for 3D modeling, texturing and rendering. Thank you in advance!

Posted February 2, 2020 If your workload is CPU-based, you're fine, the GPU doesn't matter if your workload is GPU-based, the GPU will work as hard as it can, but it will still be a 970.

Posted February 2, 2020 Author @_Syn_ @yaboistar @RadiatingLight I mainly model, texture and render. Aren't physics also done with CPU power? Tbh, I'm actually not sure what involves GPU in 3DSmax, please let me know if you do. Thank you Link to comment Share on other sites More sharing options...

Posted February 3, 2020 11 hours ago, yaboistar said: the cpu is not dependent on the gpu issuing commands to it. a slow gpu will hamper overall performance in 3d/compute tasks, yes, this is not at question, but this is not the same as a gpu being held back because the system cannot send work for it to do fast enough. Why is it not the same? everything required to execute and compute code independently is already stored in VRAM, same as the data being sent to the CPU for it to process is stored in RAM, they don't depend on each for the most part to issue commands (not intensive) but they both have to combine what they processed of their respective tasks to complete/run the program/game, and if one of them is not able to keep up or if there's performance headroom to be had then it's still called a bottleneck.

Put a Celeron with an RTX 2080 system and tell me if it makes GPU-only applications slow down to a crawl.. Quote or Tag people so they know that you've replied.

Tbh, I'm actually not sure what involves GPU in 3DSmax, please let me know if you do. As far as I know modeling is single threaded, so the 3950X won't be able to help much there, and rendering can be done with either CPU or GPU (or even both) depending on which performs faster for you, the only place where you'd see the GTX 970 bottleneck is when you have to do live physics simulations with textures and the GPU is not fast enough to render what's on screen. Yes, physics is done on CPU. Quote or Tag people so they know that you've replied. Link to comment Share on other sites More sharing options...

Posted February 3, 2020 10 minutes ago, yaboistar said: okay no, at what point did i say that wouldn't happen? infact, if i remember rightly, i said that exactly WOULD happen, ah, look, here it is No, I'm trying to say the CPU doesn't affect GPU-only applications, for example if you render with a GPU, the CPU won't be used at all. You weren't even talking about CPU-only or GPU-only applications, and I don't know why you would mention it now, what I replied is only when both of the components have tasks to complete together.

Posted February 3, 2020 Why don't you get a 3900X instead and get a nice RX5700 or a 2060Super with the difference you'll be saving? Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted February 3, 2020 So you won't have to worry about having a 970 anymore. Also, you'll be on AM4 (which i'm assuming that you're currently not atm and this is what you will be upgrading too) So your eventual upgrade path to 3950X and Ryzen 4000 will still be open rather than tapping your feet with basically the best consumer cpu out at present paired with a saggy floppy old dick of a 970 Link to comment Share on other sites More sharing options...

I think 3D modeling and rendering is more dependant on cpu performance, so your 970 probably won't hold it back at all. Link to comment Share on other sites More sharing options...

Posted February 3, 2020 Author @magicfuturealiens Well, I will mainly do CPU based actions, that's why I'm going all in on the cpu and ram. I'll wait for the 2020's GPUs Thanks Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
