No.

Thought I'd share some results from tuning OC settings on an i7-5820k with 16GB DDR4-3000 CL15.

i7/5820K, default clock and 2400MHz memory:

Code:

[Work thread Dec 29 16:19] Iteration: 4044000 / 40955561 [9.87%], ms/iter:  1.957

Which is pretty good; admittedly with six threads rather than four, it's going more than twice as fast as i7/4790K

Code:

[Work thread Dec 29 16:21] Iteration: 32905000 / 40947989 [80.35%], ms/iter:  4.033

Will look forward to measuring performance for msieve when the relations have downloaded :)

Attached FullBench results of Xeon E5 v3 @ 2.5GHz 10c/20t (105W CPU), with 4x4GB 2133 DDR4 SR ECC-R (gotta love those abbreviations

)
Some observations:

sometimes higher FFT lenght has better timings than lower FFT lenght
sometimes HT is faster than non HT
