This processor supports quad channel memory. What is your memory configuration ? You only specified the speed.

You're right, I didn't (I guess it's not obvious, though it would be rather silly to build a system like this without populating all channels).

More specific config is: Quad-channel (4x8GiB) 3200MT/s 16-18-18 2T single-rank

Dual rank would be interesting, but I don't have 8 sticks of the stuff lying around at the moment.

Here's... some data. I don't think it fully answers your question because I don't know for certain yet what frequencies max out both FMA3 and AVX512F. The table below shows various benchmarks for both. (Again this is without any OC or alteration to profiles, other than enabling XMP.)

FMA3 runs at 3.8GHz for both 8 and 10 cores. AVX512 runs at 3.4GHz for 8 and 10 cores, although with 8 1 or 2 cores would make it up to 3.7GHz periodically. Power is interesting (using HWMonitor package power, I haven't dug out the killawatt). FMA3 is 140W for 8 cores and 155-160W for 10. AVX512 was always in the 135-140W range for both 8 and 10. I'll have to play with AVX offsets more to have a better idea of what that means.

I played around with various OCs and as expected they don't make any difference in throughput (but a lot in temperature!)--the stock speed with AVX512 (apparently 3.4GHz) easily saturates memory bandwidth.

I think the short answer is memory bandwidth. That dual-socket system is quad-channel per socket (assuming you have 8x4GB). So that's ~100GB/s total theoretical system memory bandwidth, which is just about the same as on the X299 board.

Yes, all have almost all ram slots populated.
8x4.
Interesting.

I observe that the FFT implementation that has the best performance in benchmark is usually the best at P-1 stage 1, but not always so at P-1 stage 2.

For example, on a certain single-core cpu, mprime benchmark shows Pass1=512, Pass2=6K, clm=1, 2 threads to be slightly faster than Pass1=768, Pass2=4K, clm=2, 2 threads at FMA3 FFT length 3M.

FFTlen=3072K, Type=3, Arch=4, Pass1=512, Pass2=6144, clm=1 (1 core hyperthreaded, 1 worker): 16.24 ms. Throughput: 61.56 iter/sec.
FFTlen=3072K, Type=3, Arch=4, Pass1=768, Pass2=4096, clm=2 (1 core hyperthreaded, 1 worker): 17.24 ms. Throughput: 57.99 iter/sec.

Indeed, the Stage 1 P-1 performance is roughly consistent with the benchmark, although the gap between the two implementations is much smaller.

But when it comes to Stage 2, it is Pass1=768, Pass2=4K, clm=2 that performs obviously better.

I don't know what exactly caused this phenomenon, but I find it very, very interesting. We know that S2 of P-1 uses large amounts of memory, so it's not surprising if memory bandwidth impacts S1 and S2 differently. From a practical point of view, this phenomenon implies we might be able to further optimize P-1 efficiency in some cases by using different FFT implementations for Stage 1 and Stage 2, each being the best choice of the respective stage.
