I've always undervolted GPU's as it decreases watt consuption while maintaining or sometimes gaining performance.

I've never done it for CPU's and recently i bought an i7 12700 and it consumes 150-180w under load (a lot)

I spent 5 hours messing around in the bios, testing stuff out but to no avail.

My objective here is to decrease power consumption, temperatures are fine.

-I've tried disabling "ASUS performance Enhancement 3.0", base TDW decreases to 65w so I have to increase PL1 to 125w.

-Whenever I apply an offset of -0.05v, the voltage increases and temperature and wattage is the same. Any lower it decreases performance.

-Decreasing PL1 and/or PL2 wattage also decreases performance.

-Changing CPU Load-Line calibration seems to do nothing aswell (current level 3)

Is CPU undervolting not similar to GPU's? Because any voltage reduction either does nothing or leads to performance loss. Or I simply do not know what I'm doing..

Can something be done here to decrease wattage consumption while maintaining performance?

Current settings are on the images.
What I've changed:

ASUS PE 3.0: Enabled -> Disabled;
CPU Load-line Calibration: Auto -> level 3 (Auto defaults to level 3);
PL1: Auto -> 125w (auto defaults to 125w)
PL2: Auto -> 180w (auto defaults to 241w)
IA TDC and GT TDC Current limit: Motherboard's Capability -> Intel's default (for longevity)

I used Cinebench R23 first multi core cycle and HWmonitor.

Motherboard: PRIME B760M-K D4
CPU: I7 12700
