The rumor mill is back with new alleged power specifications for NVIDIA’s upcoming Ada-based GPUs, adding further potential credence of GeForce RTX 40 Series graphics cards being some of the most power hungry yet. Leaker kopite7kimi has claimed in a recent tweet that the AD102 GPU, which is expected to power the next generation of flagships such as the GeForce RTX 4090, will feature a maximum power limit of 800 watts, while some of the lesser Ada GPUs, including the AD103 and AD104, are said to feature power limits of 450 and 400 watts, respectively. GeForce RTX 40 Series mobile GPUs will supposedly feature a power limit of up to 175 watts. NVIDIA’s current gaming flagship GPU, the GA102, features a 450-watt maximum TDP.
A truth. The power limits:— kopite7kimi (@kopite7kimi) June 18, 2022
AD103 (DT), 450W, AD103 (Mobile), 175W;
AD104 (DT), 400W, AD104 (Mobile), 175W;
AD106 (DT), 260W, AD106 (Mobile), 140W.
But I don't think we need to use the full power cap.
It is important to note the difference between power limit and TDP of actual GeForce SKU. The TDP should almost certainly be lower, while the power limit will lock overclocking from reaching a higher value. Therefore, the listed power limits may not necessarily apply to TDP of RTX 4090/4080/4070 and 4060 series, but rather how much power can be applied by board partners and through manual overclocking.
