A new set of purported NVIDIA GeForce RTX 3080 Ti specifications suggest that it will come with 10,496 CUDA cores like the GeForce RTX 3090. However, its 20GB of GDDR6x VRAM has a memory speed of 19GB/s, putting it closer to the GeForce RTX 3080, along with its 320W TGP. Support for Nvlink appears to have been removed too.
