The goal of this project is to remove the constant compilation of kernels, and to up the performance, probably surpassing similar spec GPUs from other vendors.
The constant compilation of kernals has put me off considering AMD GPUs for Cycles and if you can bring more performance and even surpass nVidia this could be game changing.
I look forward to seeing your commits in due course.
Life is hard.
Correct me if I’m wrong but Blender Institute is supported by AMD. It seems that they are paying for the work of the Blender OpenCL developers.
Apple had to extend Metal for Redshift and currently kernel compilation is dog slow, oh yes, it’s not even released yet.
AMD is developing ProRender and that requires constant kernel compilation. You’ll have to ask Nirved what they are proposing to do that others haven’t been able to do. OpenCL has never been friendly to 3d renderers and even Apple starting again with Metal didn’t make it any easier.
I guess your informations about Metal are not up-to-date. OTOY developers did this. What’s more they claim Metal Octane X is ahead of CUDA version and they are waiting for updated Nvidia drivers to be able to create a CUDA version at the same level as Metal.
Would be great using AMD GPUs. Rumours seem to point to them having more VRAM than the 3080. No point in having a fast GPU if the scene doesn’t fit in VRAM.
“We actually have things in our Octane X today that aren’t in the CUDA version, there are some new memory features, some memory optimizations are already in the Metal version, One of the things that we’re going to add early next year is to bring both versions up to speed, and then you’ll actually have the ability to network those two together and mix and match CUDA and Metal cards, at least for network rendering, which will be interesting”
Big Navi supports HW raytracing. OTOY claim they will add this to the Octane X when Apple will add HW RT support to Big Sur Metal drivers. However they are not sure performance or can’t talk about this at the moment.
Good catch, I meant nVidia drivers as a whole in this case Optix.
I’m not attacking you, I have read OTOY’s fantastical claims for years. I’ll believe them when I see the evidence. My default position is to take everything OTOY says with a huge pinch of salt.
