On our rating lines the RTX 5070 (66) and RTX 4070 Super (64) land on the same verdict at every resolution, so the 2-point index gap does not move either card into a different class. Memory, power and the price you can find decide it.
Power, PSU and efficiency
Reference board power is 250W for the RTX 5070 and 220W for the RTX 4070 Super, a 30W difference. Per 100W that works out to 26.4 index points for the RTX 5070 and 29.1 for the RTX 4070 Super, so the RTX 4070 Super does more per watt. Both makers list the same 650W supply. Only the RTX 5070 is a current-generation card; the other is mostly found as remaining or used stock. Full sizing: RTX 5070 PSU · RTX 4070 Super PSU.
