I don't run "stock" mode (TDP=105/PPT=142 on my 3950X).
Here's some data on TNGrid that I collected some time back.
CPU: 3950X
MB: Gigabyte aorus master x570
RAM: 64 GB DDR4-3200
PSU: Seasonic Prime TX850 titanium
VC: Radeon VII (idle power draw is 20 watts according to sensor output)
Power is measured in watts at the wall minus 20 watts for the video card
All threads (32) are running TN-Grid tasks
TDP (105 watts) and PPT (105 watts) set in bios
Power draw at the wall: 161 watts
Boinc benchmarks...double precision 7032.64 million ops/sec....integer 71863 million ops/sec
3.893 GHz clock speed <----the effect of instruction sets such as avx must be minimal...on SGS LLR tasks the clock was 3.5 GHz
5.65 Gflops/thread....180.8 Gflops/host....1.12 Gflops/watt
Average CPU time (40 tasks): 9,654.9 s (STDEV=78 s)
Average points per task: 136.8
PPD: 39,188.4
PPD/watt: 243.4
TDP (65 watts) and PPT (65 Watts)
Power draw at the wall: 116 watts
3.03 GHz clock speed
Boinc benchmarks...double precision 6339 million ops/sec....integer 63960 million ops/sec
5.65 Gflops/thread <-----I didn't do the calculations here since this number didn't change after I reran the benchmarks so it can't be accurate
Average CPU time (60 tasks): 12,795 s
Average points per task: 147 <----this # went up a bit so I wonder if this is because the Gflops/thread # didn't drop as expected.
PPD: 31,840.5
PPD/watt: 274.5
Summary on above data:
Numbers I think I can trust are task CPU time, clock speed, and power draw at the wall. The power draw at the wall number is contingent on the idle power draw number of the Radeon VII reported in the OS (20 watts).
So going from 65 watt PPT to 105 watt PPT:
Clock speed: 3.03 GHz --> 3.893 GNz is a 28.5% increase
Power draw: 116 watts ---> 161 watts is a 38.8% increase
TN-Grid task CPU time: 12,795 s ---> 9,655 s is a 25% decrease
