Can you also do 4w (16t per w) as well? For wavefront exponents, 8 worker will not fit entirely within L3, but 4 worker will.

Also, what is your RAM speed?

EDIT: 4096K FFT and higher would suffice. Smaller ones will not see any benefit

Ok. These are definitely showing better thruput compared to 8w tests.

There is a chance that you may get slightly higher thruput by optimizing Infinity Fabric speed. By default IF runs at RAM speeds. So 3200 RAM gives IF speed of 3200 (or is it 1600? doesn't matter). Either running 3600 RAM or explicitly setting higher IF speed in BIOS may improve thruput slightly in this case.
