All right, one 3900X owner ran the mprime benchmarks for me, same methodology in plotting as before. The 3900X is thus over two times faster than the 3600 within a certain range of FFT sizes, from 5120K to 7680K. 2.45 ms/iter at the wavefront, 5120K... Certainly the effect of the larger L3 cache can be seen. He has 3000 MHz memory in the system, no idea about latency. No system tuning done, so I assume that fclk is just 1500 MHz.
