The latest rumors from Chinese Chiphell forums claim that NVIDIA has scrapped the 16GB variant of the GeForce RTX 3070 Ti, and delayed the launch of the RTX 3090 Ti to the 29th of March. The former was supposed to replace the RTX 3070 Ti 8GB as its VRAM buffer is no longer enough in newer AAA titles, most notably Far Cry 6, Resident Evil VIII, etc. Going by the rapid adoption of DLSS, and GeForce partner titles, I reckon NVIDIA decided against it.

Meanwhile, the GeForce RTX 3090 Ti which features the full-fat implementation of the GA102 die is reportedly launching at the end of the month. Chiphell sources place the launch of the 10,752 core SKU on the 29th of March. With 24GB of GDDR6X memory paired with a 384-bit bus, the 3090 Ti will be the first consumer GPU to push the 500W TBP mark. While the Founders’ Edition model will have a TBP of 450W, custom AIB models featuring water-cooling will have a power limit of 520W, a prelude to 600W RTX 4090/4090 Tis.
