NVIDIA's GeForce RTX 3070 Ti graphics card has been confirmed in a listing by Lenovo for its Legion T7 gaming desktop PCs. The GeForce RTX 3070 Ti slots right between the GeForce RTX 3070 and the GeForce RTX 3080 but the main difference that the card features is its huge memory size compared to the other two models.

You might remember that there were rumors about NVIDIA offering its GeForce RTX 30 series line in both the standard and doubled VRAM flavors. The NVIDIA GeForce RTX 3070 Ti seems to be one of those designs which features double the VRAM of the GeForce RTX 3070. The card is equipped with a total of 16 GB GDDR6 memory which should run at the same speeds of 16 Gbps alongside a 256-bit bus interface. That should lead to a total of 512 GB/s of bandwidth.
