Building a setup for a friend using an Asus 4070 dual. Decided to test UV.
Unigine uperposition:
Stock:
2800-2900@1050-1070mv 180-195W 9646 points
UV 2700@915mv +500vram oc 125-135W 9139 points

For 25% lower power I get 94-95% of the performance which is quite good I guess :)

Voltage will not go below 910mv no matter what. At 910mv vram downclocks to 5000MHz making performance suck. Undervolting Ada is somewhat limited vs Ampere and Turing that could do 700-750mv. This allowed for 40% powersaving at 88-90% of performance.
