The NVIDIA GeForce RTX 4080 may have a TGP that’s 100 watts higher than the GeForce RTX 3080 (10 GB). That’s according to the latest speculation from recurring leaker kopite7kimi, who now believes that the second-most-powerful GeForce RTX 40 Series model that will be available to enthusiasts at launch could feature a 420-watt TGP. NVIDIA’s GeForce RTX 3080 with 10 GB of GDDR6X features a TGP of 320 watts, while the newer model with 12 GB of GDDR6X features a TGP of 350 watts—a specification echoed by the GeForce RTX 3080 Ti. NVIDIA’s flagship GeForce RTX 4090 graphics card has been rumored to feature a TGP of anywhere between 450 to 600 watts.

Power increase for RTX 40 graphics cards should no longer surprise anyone. Over the weekend, the same leaker also revealed that the RTX 4060 SKU, which is expected as late as next year, would have higher TDP than the current-gen RTX 3070 model. Just assuming it’s 220W, the TDP would increase by 50W for XX60 class model.
NVIDIA GeForce RTX 4080 graphics card may launch between September and October this year. However, it is very likely that NVIDIA will be announcing this SKU alongside RTX 4090, which is expected to be released sooner.
