Anyway, as I mentioned recently, I have a new workstation that finally allows me to test our code using all three backends (#CUDA, #ROCm/‌#HIP and #CPU w/ #OpeMP) thanks to having an #AMD #Ryzen processor with an integrated #GPU in addition to a discrete #NVIDIA‌ GPU.
Of course the iGPU is massively underpowered compared to the high-end dGPU workhorse, but I would expect to outperform the CPU on most workloads.
And this is where things get interesting.
