The power consumption of NVIDIA’s next-gen GeForce RTX 40 series graphics cards have been a topic of hot discussion. Till now, a lot of rumors have popped up claiming TGPs of up to 900W for the top-end RTX 4090 Ti. While popular tipsters have largely downplayed these figures, Kimi has shared the actual power limits of the four Lovelace dies:
The AD102 core which is set to power the RTX 4090 and the RTX 4090 Ti will have a peak power draw of 800W, although as Kimi states, the maximum limit will likely not be utilized. Instead, we’re likely to get a peak TGP of 450-550W for the RTX 4090 and 650-700W for the RTX 4090 Ti. Meanwhile, the RTX 4080 will get a TGP of 400-450W on the desktop and 150-175W on the mobility variant.
The midrange RTX 4070 leveraging the AD104 GPU core will have a peak TGP of 400W, indicating a power spec of 350W. The mobile variant will have the same power figures as the RTX 4080 mobile at 150-175W. Finally, we have the RTX 4060 which will be based on the AD106 die. The desktop variant will have a TGP of 200-260W while the notebook part will top out under 140W.
As already stated in the beginning, these are the maximum supported power draws by these dies, and NVIDIA is unlikely to push them to the max, at least on the reference models. The extreme OC liquid-cooled variants may come close but the air-cooled variants should run a fair bit under these limits.
