i am not a native english speaker.
i started investigating many complaints about the 5800x running very hot.
in the last 14 days i tried over 200 different PBO tweaks to get the most out of my Chip.
the 5800X sits on a B550 STRIX-F and is cooled by a Kraken X73.
even with 100% Pump Speed i get like 78-85°C in Cinebench R20... and the reason is pretty clear.
the 5800X has the same power/current limits as a 5950X. (142W PPT, 140A EDC, 95A TDC)
that means the cores consume around twice the power on the 5800X.
after AMD said "this is normal and expected" i started living with it and tweaked it with PBO.
after a specific "benchmark" from me in Rainbow six siege (a custom map with the indentical paths, destroying specific walls with the same operator)
i ran every benchmark 15 times with stock, and the two most successful PBO tweaks.
Results for Rainbow Six Siege:
Stock Mainboard Settings with DOCP on.
all Cores were between 4.35 and 4.5 Ghz with an average all core clockspeed of around 4.43 Ghz. (average VCore 1.403 and 63°C) Average FPS 309
PBO PPT 180 / TDC 140 / EDC 180. 2X Scalar, 100 Mhz Offset.
all cores were between 4.45 and 4.55 Ghz with an average all core clockspeed of around 4.48 Ghz. (average VCore 1.437V and 67°C) Average FPS 313
PBO PPT 200 / TDC 165 / EDC 200. 4X Scalar, 150 Mhz Offset.
all cores were between 4.45 Ghz and 4.58 Ghz with an average all core clockspeed of around 4.52 Ghz. (average VCore 1.465V and 72°C) Average FPS 314
Results with Cinebench R23:
Stock:
1609 SC / 15533 MC (78.8°C 1.331V @ 139W)
4850 Mhz / 4500 Mhz
PBO PPT 180 / TDC 140 / EDC 180. 2X Scalar, 100 Mhz Offset:
1623 SC / 15549 MC (81.5°C 1.34V @ 144W)
4950 Mhz / 4525 Mhz
PBO PPT 200 / TDC 165 / EDC 200. 4X Scalar, 150 Mhz Offset:
1641 SC / 15602 MC (86.1°C 1.365V @ 153W)
4975-5000 Mhz / 4550 Mhz
then i started taking some Power off the CPU and let it do it's thing. (Using PBO with the following settings reduced the performance as much as -200 MHz)
DOCP + Changing Powerlimits in PBO without changing any Scalar or Clockspeed Offset.
PBO PPT 105 / TDC 70 / EDC 90
Rainbow Six Siege:
all cores were between 4.58 Ghz and 4.72 Ghz with an average all core clockspeed of around 4.67 Ghz. (average VCore 1.38V and 61°C) Average FPS 324
Cinebench R20:
1611 SC / 15091 MC (64.8°C 1.2V @ 105W)
4850 Mhz / 4425 Mhz
The results are the biggest improvement so far.
Gaming and other lighter Tasks are much faster than PBO while consuming way less power.
Only the Multicore performance is around 3.5% lower while consuming around 33% less power.
i am currently trying this in other applications like Blender and other/heavier Videogames like Battlefield V and Cyberpunk 2077.
i highly recommend testing this for yourself
