This convinced me to play around with undervolting and I managed to do -50/-50/-40 (cpu/gpu/soc) while still passing furmark and all mprime tests, now I can play Stardew Valley for even longer!
The performance boost in Hitman 3 is interesting. Probably results from being able to keep a more consistent clock speed during intensive scenes because of lowered temps
I was just about to ask how undervolting could possibly improve performance. Your explanation sounds pretty plausible.
Am I reading this right? The games performed better with less power? Why?
Think of amps and volts like a hose and water. If you put your thumb over the hose the water shoots out faster. Undervolting works in a similar way. So the goal is to lower the volts but maintain or even increase the amps to improve performance.
Undervolting provides the chip with additional power and thermal headroom, and can improved situations where otherwise throttling sets in.
