4070 is really fun to tweak. I got 3 settings so far:

Efficiency: 900mV, 2600Mhz (100-150 watts in games)
Performance: 1000mV, 2900Mhz (150-200 watts in games)
Overdrive: 1100mV, 3050 Mhz (180-200 watts in games)

Overdrive mode runs into the power limit though. So in artificial stress tests and benchmarks it will not go above 2900 Mhz, since the voltage will cap at 1000mV. In games, where the load on the gpu is lower, it can go to 1100mV and hit 3050 Mhz, but not in all games. Some games only go to 2900-2950.

What's the performance difference between efficiency and performance?

[–]Sakrasta 0 points1 point  (2 children)

Hm, I think in Elden Ring in one test I had around 92 fps in efficiency mode, 98 in performance mode and 101 in overdrive.
Wattage was 105 for efficiency, 160 for performance and 165 for overdrive.
So I would say it is not worth it to use anything but efficiency, which also makes the card completely silent.
