GPGPU: Compute render performance
GPGPU: - Blender and Indigo
Blender offers a wide variety of options and APIs, depending on your graphics card. We fire off a scene where we render a Classroom - we only allow the GPU to render in the benchmark application. There are API related challenges to address with Blender though:
- AMD Radeon cards support OpenCL solely
- NVIDIA GeForce cards up to Pascal support CUDA - but not OpenCL or Optix
- NVIDIA GeForce RTX cards based on Turing can be assigned CUDA or OptiX - but not OpenCL
Where OptiX is not possible we run CUDA. OpenCL is not available for GeForce cards. The Radeon graphics cards have just one option, OpenCL. Ergo we choose the fastest API available for the graphics card we test.
Due to a change in the benchmark, we are starting from scratch again with blender results.
