Yes. Very much so.

Does CUDA matter for DaVinci Resolve Studio performance?

Hi.

In Resolve the CPU is used to run the app, disk I/O, fusion, compression and decompression of codecs.
Resolve does all its image processing in the GPU on the graphics card. More CUDA/OpenCL Cores are better.

In the paid STUDIO Version of Resolve, can certain combination of Codec, Resolutions, Bit width and Chroma subsampling be hardware decoded/encoded on either a AMD/nVidea Graphics card or in a Intel non Xeon CPU. Then you can use a little less powerfull CPU.

Regards Carsten.

The GPU specs that most effect performance are CUDA Cores, Memory Bus and Memory Size, with higher numbers being better.

Igor, Carsten, Jim, thank you. I took into attention.

CUDA is in Nvidia GeForce. OpenCL is in AMD Radeon. Am I right?

What is better for DaVinci Resolve Studio performance: CUDA Nvidia GeForce or OpenCL AMD Radeon?

if you use OFX that do not run on OpenCL then the answer is CUDA

I have used both in my Hackintosh and both types of cards work well. The amount of memory usually makes the most difference.

Thank you everybody for information. I took into attention.

This is not entirely accurate. OpenFX either have some permutation of GPU implementation (OpenCL, CUDA or Metal) + CPU or are CPU only.

Generally, if an OFX plugin has CUDA support, it should have OpenCL support as well.

This is purely developer dependent. Ofx does not enforce any gpu processing, it is all up to developers to add it and there is nothing that would force adding opencl support together with cuda. These gpgpu apis are different and adding one adds no support for another automatically.

Completely agree with what you're saying. However, I'm thinking as a developer here. If I've gone through the hassle of adding GPU acceleration such as CUDA, it's not a significant burden to add OpenCL support as well.

Thank you everybody. I took information into consideration.
