New leak sheds light on a 900W AD102 based graphics card from Nvidia; GeForce RTX 4080 and RTX 4070 VRAM and TGP also revealed
Over the past few weeks, multiple leaks about Nvidia's upcoming RTX 4000 series graphics cards have popped up online. A common theme among them was the power consumption of some of the higher-end models, with one report suggesting that a PCB could easily support 600W of power. Now, renowned leaker @kopite7kimi says that Nvidia is testing yet another high-end graphics card with the AD012 GPU.
The mystery graphics card will draw a whopping 900 Watts of power, feature 48 GB of 24 Gbps GDDR6x VRAM and ship with two 16-pin PCI-e Gen 5 connectors. This information sits in line with an earlier report, which said that Nvidia's Ada Lovelace based graphics cards would push PSU requirements through the roof. However, there is no telling if the SKU in question will ever see the light of day.
One can rule out the possibility of the aforementioned graphics card being a gaming product for several reasons. For starters, even the top-of-the-line GeForce RTX 3090 Ti capped out at 24 GB of VRAM and that is unlikely to change with the GeForce RTX 4090. Additionally, the amount of VRAM is nearly identical to the the Amepere-based RTX A1000 launched last year. The SKU in question, is very likely a successo or a Titan-branded card that could finally make a comeback.
In a follow up Tweet, Kopite says that the GeForce RTX 4080 will use an AD103 GPU with 16 GB of GDDR6x VRAM (18-21 Gbps) and draw as much power as a GA102, meaning that it could gobble up to 400 Watts. Performance-wise, it should ideally outperform a GeForce RTX 3090 Ti with its improved architecture and 10,752 CUDA cores. Its younger sibling, the GeForce RTX 4070, will use an AD104 GPU, feature 12 GB of GDDR6 VRAM and have a TGP of 300W.
Nvidia's decision to use a separate GPU for every graphics card is quite interesting, especially considering when it reused the same GA102 GPU for several Ampere-based cards. Improved yields from TSMC's 6 nm manufacturing process combined with better part availability could have finally permitted Nvidia to spread its wings a little, althogh it will need all the processing power it can get to take on the multi-die Navi 31 GPU from AMD.
