WebApr 27, 2024 · If you employ the c2r case with additional copying, the GPU has to make a lot more computation than fftw does in r2r case (2(N+1)-size transform instead of just N), and more memory allocations must be done, so it won't be as fast as with r2c or c2c cases. But that according to my experience even older mainstream GPUs are a lot faster than CPUs ...
