In this paper, we present the results of comparison of the effectiveness of selected variants of radix-2 Fast Fourier Transform (FFT) algorithms implemented on both Graphics (GPU) and Central (CPU) Processing Units. The considered algorithms differ in memory consumption and the arrangement of data-flow paths which affects the global memory coalescing and cache memory exploitation. The obtained results allow to indicate the variants of FFT algorithms which are best suited for GPU and CPU architectures, to confirm the advisability of GPU oriented calculations of FFT and to formulate a guideline for implementations of fast algorithms of various linear transforms.
