Hello everyone, I need to upgrade my PC, but I would like to know if Raytraced uses only CPU or also GPU to render. Today I am using an i7 2600K with a GTX560ti, and looking at the Windows manager, only the CPU appears to be used. Does Raytraced not work with GPU?
The Raytraced display is based on Cycles.
If your current graphics card and driver support CUDA or OpenCL, then they will show here and will speed up the Raytraced display calculations:
I’m running an Intel Iris so there is no GPU option.
But if you are thinking an Nvidia GPU (CUDA) or AMD GPU (OpenCL), for the first the RTX line should work fine, and the Vega for the second, probably Navi too (but I haven’t tested that, so not sure).
So yes, Raytraced is able to use the GPU if supported. If possible you could get two GPUs so one does the regular GUI/Desktop, and a dedicated one for GPU rendering.
Thank you in advance for your help. I believe the GTX560Ti does not support Cuda, the option appears empty in Rhino. As for the processor, AMD or Intel? Which model would be a good choice for Rhino and Raytraced?
The GTX 560 Ti supports CUDA, but the version it supports is too old. The card is based on the Fermi architecture, and for Raytraced that architecture was quite a while ago discontinued.
I don’t know what CPU would be best.
I have a Navi GPU with 8 gigs of HBM2 memory that works great in Rhino and everywhere else. I will however eventually upgrade to an Nvidia so that I can take advantage of other rendering engines that utilize their cuda processes.
Thanks for the information!
What about Quadro? They cost more, but would they be better options than a current GTX?
From 2104. The hip/sarcastic tone is annoying, and it’s intended for gamers. However, assuming the manufacturing /marketing methodology is still the same…?
I think it’s pretty much right on the mark. How does it affect Rhino users? McNeel asserts Geforce cards will work fine and I haven’t seen much to contradict that over the years I’ve been hanging around this forum. (Well, there was an era when there was a bit more whining about Geforces, but recently not so much.) I personally have gone for middle-of-the pack Quadros whenever I’ve felt the need to upgrade and have NEVER had any hardware or driver issues. All those happy Geforce users may think I’m wasting money, but heck, I’d probably just spend it on wine, women and song otherwise and I can’t get a note from my wife giving me permission to do that anyway.
My vote is for an RTX card. I use the prior generation GTX 1080 ti and it has worked great for years. No need to spend extra for a Quadro card.
For my CPU I use an Intel 9980XE. It has 18 cores (36 threads) which I fully exploit in my Python/C++ scripts. It let’s me use 15-way parallel reading and parsing to import a point cloud 250 times faster than Rhino’s Import tool: a 100M point cloud can be imported in under 20 sec vs 1 hour with Rhino Import.
My understanding is that what you’re buying with the RTX isn’t used by Rhino and probably won’t be for several years. So the thing to look at is cores/$ when comparing with the GTX’s (which I believe are still available).
Yes get a GTX if you can. The performance difference of RTX vs GTX is small compared to the jump from your current setup.
