Almost since the rumor mill began, there have been hints that the RTX 4000, codenamed Ada Lovelace, is going to need a large capacity power supply for her alone. Recent rumors coming from leakers Kopite7kimi and Greymon55 now indicate that the flagship GPU, the AD102 (presumably called RTX 4090), could consume more than 800 watts of power
In addition, its launch would be very close: from September 2022. Both leakers the AD102 GPU will have multiple commercial models for the RTX 4080, RTX 4080 Ti and RTX 4090 desktop graphics cards. They would have different power requirements, such as the GPU input will reach 450 watts of maximum consumption, the Ti variant with around 600 W, and the flagship RTX 4090 would go up to those 850 W.
They insist that the Ada Lovelace will consume a lot
Both filters warn that not final specs and could change into retail variants. But WCCFTech believes that not much is likely to change, as NVIDIA is already investing in the development of the new PCIe Gen 5 connector that offers up to 600W power input per connector. The RTC GeForce RTX 3090 Ti that is being delayed would be an example of this given that it is expected to reach 450 W, which would make it the first desktop graphics card to use such a connector interface.
In the case of the Ada Lovelaces, they could end up with two PCIeGen 5 connectors to meet the power requirement of about 800W. Users will need to use a 2x 8-pin to 1x 16-pin adapter that will ship with most of these power supplies since power supplies would only have one as standard.
They encourage you to think that these rumors are true that NVIDIA would want to give everything to overcome the AMD's RDNA 3. The NVIDIA AD102 “ADA GPU” is expected to have 18432 CUDA cores according to preliminary specifications provided by Kopite. This is almost double the cores present in the Ampere graphics cards, which at their 2,2 GHz clock speed would deliver 81 TFLOPS of computing performance, which would be more than double the performance of the RTX 3090.
