Leaked pictures of Gigabyte's GeForce RTX 3080 Ti graphics cards confirm that NVIDIA was at some point planning to incorporate 20 GB memory capacity on its new flagship.

First, the company submitted products to the EEC or Eurasian Economic Commission. They are the platform of conformity to South Korean standards. A few months passed, and Gigabyte released more product IDs that showed that they were instead going for 12 GB GDDR6X memory versions of the GeForce RTX 3080 Ti graphics card which was later confirmed to be the final configuration for the graphics card.
