In general, a radix-4 FFT will run faster than radix-2 FFT but will take up more space and has more restrictions on the length of the FFT. Specifically, all radix-2 FFT routines will take data lengths that are any power of two (>= 32 points) while complex radix-4 routines will only take data lengths that are a power of four (>= 64).
