The news on NVIDIA's next-gen Ada Lovelace GPU-powered GeForce RTX 4080 is from leaker "kopite7kimi" who tweeted: "We can expect RTX 4080 with 320W and RTX 4070 with 285W". The previous rumor for the RTX 4080 is that it would use 420W, so the drop to 320W is a lofty 100W... and that's a great thing.

NVIDIA has an additional 100W of power it can use for some monster overclocking on custom GeForce RTX 4080 graphics cards, something kopite7kimi addressed in a follow-up tweet, by saying: "Not much. The original power consumption limit is too loose which means great overclocking potential".
