Should I use CUDA or OptiX?

Long story short, OptiX is much faster for Blender than using NVIDIA’s CUDA back-end — which already was much faster than the OpenCL support within Blender. OptiX is only supported with the NVIDIA RTX graphics cards but it offers a significant boost to the rendering performance.

What GPU is needed for Blender?

Graphics card should be 1GB, OpenGL 3.3 or better. 500 MB of free disk space is a must. For Linux recommended requirements, use Ubuntu 19.04. As for the processor/CPU, use Intel Core i9 or equivalent.

Is OptiX faster than CUDA Blender?

Does AMD support OptiX?

If your GPU is not Nvidia or it is not RTX (for example, GTX series), OptiX won’t work. There is a Blender development blog post to explain it more. And for OpenCL, it is for an AMD GPU to utilize the hardware since AMD doesn’t support CUDA at all.

Which is best RTX or GTX?

Nvidia GeForce GTX has a range of performance in the long run. It has Ultra-fast GDDR6 memory and advanced graphics cards that bestow the best gaming experiences. Nvidia GeForce RTX is renowned for being the best performing graphic card, which brings real-time light simulation to users while gaming.

Are Cycles ray tracing?
