Use CPU(KL) to run FFT of Intel IPP takes longer than CPU(HL)

Customer uses related Fast Fourier Transform(FFT) part of Intel Integrated Performance Primitives(IPP) to get calculated result (Please refer attached file).
Why use a new generation of CPU (Kaby Lake)) to run FFT of Intel IPP will takes longer than the previous generation of CPU (Haswell)? Could you expain this phenomenon? Thanks.

Any sample code which is shareable and can reproduce Fast Fourier Transform(FFT) performance issue observed at your end.

Richard,

which FFT do you mean: signal processing (1D) or image processing (2D)?

In any way I recommend to use one OS for perf measurement. win7 vs win10 - there are can be some patches for security vulnerability affect performance.
