The poster confirms the card will use a GA102-350-A1 GPU with 10752 CUDA cores and he claims the TGP may even be higher than 450W. Basically, this means 100W more than the RTX 3090. If this is accurate, this means we'll see a lot of cards with three 8-pin PCIe power connectors.
The memory is said to be 21Gbps GDDR6, a first for NVIDIA's GeForce RTX 30 series. Current top models use 19.5Gbps GDDR6.
Lastly, there's the claim that there will be no NVLINK support. This suggests NVIDIA is dropping support for NVLINK entirely on its consumer lineup. At the moment, the only new GeForce card that has NVLINK is the RTX 3090. If the SUPER version lacks it, it means multi-GPU is truly a dead end for NVIDIA's consumer cards.
