What are the performance differences for iray between NVIDIA’s GeForce, Quadro, and Tesla products in 3ds Max?
NVIDIA GPUs vary in their compute performance according to the number of CUDA cores they have, the GPU’s clock speed, and the GPU’s architecture. The GPU brand will not impact iray performance beyond these characteristics. Put into formulae, GPU ray tracing performance looks like this: (CUDA Cores#) x (Clock Speed) x (GPU Architecture) = Relative Performance. This means that for a given GPU architecture and clock speed, iray performance will scale linearly with the number of CUDA cores present on the GPU, and for a given architecture and core count iray will scale linearly with clock speed. The GPU family (Quadro, Tesla or GeForce) does not have additional influence on how iray uses it.
