WebCUFFT Performance vs. FFTW Group at University of Waterloo did some benchmarks to compare CUFFT to FFTW. They found that, in general: • CUFFT is good for larger, power-of-two sized FFT’s • CUFFT is not good for small sized FFT’s • CPUs can fit all the data in their cache • GPUs data transfer from global memory takes too long ...
