Phoronix: Blender 3.2 Performance With AMD Radeon HIP vs. NVIDIA GeForce On Linux

This week's release of Blender 3.2 brings AMD GPU rendering support on Linux via AMD's HIP interface in conjunction with their ROCm compute stack. Eager to see the AMD GPU support on Linux finally arrive, I quickly began trying out this new Blender open-source 3D modeling software release while seeing how the AMD RDNA2 HIP performance compares to that of NVIDIA GeForce RTX 30 GPUs that have long enjoyed top-notch support under Blender.

Was absolutely expecting that, slow, minimal hardware support and sigsegv festival on most hardware.

Shocking! It's gimped at the design level. That's trinkets well spent on blender devs by nvidia.

My 6700XT does not work with https://github.com/sukhmeetbawa/OpenCL-AMD-Fedora and Blender 3.2

The ~10x cost Δ of the gpus seems relevant when performance testing.

Edit: The cost is 10.6x and the seconds are 22.2x resulting in a 4.4x dollar second win for The Nvidia GeForce RTX 3080.

(_'s because Michael did not put the Forum code on github)

Nvidia is superior in any case.

[aufkrawall]

What is worse? RDNA2 RT or AMD's software support?

[Lbibass]

I'm not surprised in the slightest. Nvidia can spend millions on software support for their products, enhancing their stranglehold on the market. I hope that over time AMD's software support can get better.

I miss a bit CUDA performance of Nvidia from those graphs. I still expect AMD to be behind CUDA, but given how problematic AMD setup is I wouldn't consider it to be production ready.

If it'd be allowed to express wishes, I'd like to see a final Performance Per Watt graph.
