One card that has been named quite a number of times is the GeForce RTX 3060 Ti, word right now is that it'll launch December 2nd and will get 4864 shader cores.

A Chinese site talks about 4864 shader cores and 8 GB of gddr6 memory. The graphics memory would have a 256-bit memory bus and a speed of 14 Gb/s, good for a bandwidth of 448 GB/s. Based on the GA104-200 GPU it would get a base frequency of 1,140 MHz and a boost at 1,665 MHz. That one holds with 6 GB GDDR6. Prices of the Chinese webshop would suggest a price of around 378 euros. While the Ti is a sure thing release wise, there would also be a non-Ti product later on. Expreview reports that the 3060 Ti will be delayed by two weeks towards 2 December as the availability date. It is not known why the introduction has been pushed back two weeks, but limited availability of all Ampère cards might have something to do with this.

Update 2: In a new leak, performance slides from NVIDIA have leaked on the pending 3060 Ti. The graphics cards were tested with stock clocks at 2560×1440 resolution using Intel Core i9-10900K CPU. The results look very promising as the card would beat even an RTX 2080 SUPER. While the GeForce RTX 2060 Super is usually clearly beaten in all games and the synthetic benchmarks used, the GeForce RTX 2080 Super also has to admit defeat to the new GeForce RTX 3060 Ti in the disciplines of rasterizing, ray tracing and rendering.
