I hope this question fits here because is touches two different products...
Is the FFT perfomance of the MKL simular or equal to the performance of the IPP (Intel Performance Primitives) FFT? So, is it worthwhile to buy the MKL if one already has the IPP, when it comes to FFT performance?
MKL provides not only performance. If you process large volume of data (megabytes), have interleaved data,do multidimensional FFTs, want to multithread your app, etc, thenMKL has no alternative in IPP.
