Ryzen 5900X [ PBO default VS undervolting CUSTOM ]
Test benchmark ingame shadow of mordor
PBO default and after Undervolting CUSTOM
98 FPS both cases
We can see that the number of fps is the same
The difference in consumption and temperature is obvious
VCORE PBO default : 1.45V at 4950mhz max
VCORE CUSTOM : 0.88V at 4000mhz
Consumption is even lower when I limit it to 60 fps, here I unblock to show it well when the GPU is used at 100% there is no difference in performance.
