With RTX 3080 and RTX 3090 now officially available, Nvidia is gearing to launch its RTX 3070 on October 15th, but according to the latest information, it appears that the RTX 3060 Ti will also be coming by the end of October.
There were a couple of leaks from Gigabyte and Galax, which have pretty much confirmed the RTX 3080 20GB as well as the RTX 3070 Ti 16GB, but those will wait for AMD's Radeon RX 6000 series lineup.
According to Videocardz.com, confirming it from two sources, the RTX 3060 Ti will be based on GA104-200 GPU with 4864 CUDA cores, or 1024 fewer cores than the RTX 3070, and pack 8GB of 14Gbps GDDR6 memory on a 256-bit memory interface, leaving it with 448GB/s of memory bandwidth. The TDP is set at around 200W for custom boards, which suggest that the reference board could be 180W, which is slightly higher than the RTX 2070 and RTX 2060 Super.
The precise launch date is not confirmed and it is surprising that Nvidia will first launch the Ti version of the RTX 3060, while the standard one, as well as RTX 3070 Ti, could come after AMD's RDNA2 launch, giving Nvidia room to counter AMD's moves.
Nvidia has a decent headstart and although it is struggling with availability and custom board issues, the RTX 3080 appears to be selling well, and partners are getting more stock and clearing out possible issues, so things should be better soon.
