According to details posted over at Videocardz.com, the RTX 3060 Ti Founders Edition, should be based on the GA104-200 GPU with 4864 CUDA cores, 38 RT cores, and 152 Tensor Cores, as well as come with 8GB of 14Gbps GDDR6 memory on a 256-bit memory interface.
The RTX 3060 Ti Founders Edition cooler looks pretty similar to the one on the RTX 3070 Founders Edition, with a dual-slot dual-fan configuration.
According to Nvidia's own slide, the RTX 3060 Ti should end up slightly faster or in line with the RTX 2080 Super, which is pretty impressive considering it will launch with a $399 price tag. This SKU is expected to officially launch on December 2nd.
