WebJul 27, 2008 · The x86 is roughly 1.3 - 1.5 times as fast for a 1024x1000 array. The FFT code for CUDA is set up as a batch FFT, that is, it copies the entire 1024x1000 array to the video card then performs a batch FFT on all the data, and copies the data back off. The only difference in the code is the FFT routine, all other aspects are identical. http://www.fftw.org/speed/ galeria kaufhof plan
