I just implemented a 2D image convolution filter based on both AMP FFT and the FFT method in Math.Net Numerics, and on my system (Core i7 / GeForce GT 640) Math.Net Numerics wins.
Basically this means that I would rather rely on Math.Net Numerics since it does not require a DX11 GPU.
Does anyone have similar experiences? Any chance that AMP FFT will be optimized further?
