There have been many rumors about GeForce RTX 3080/3080 Ti variants with 20 GB of VRAM. It seems that at least one of these early prototypes were sent to AIBs. Someone in Russia managed to purchase a GIGABYTE GeForce RTX 3080 Ti Gaming OC with 20 GB of memory for roughly $3,070.
No drivers are available for the graphics card, which means there’s only one thing it can be used for: mining. The owner tried reaching out to GIGABYTE Russia for drivers but was told that the card doesn’t exist.
The card came pre-configured with overclock core and memory settings. When tested using Gminer or NBminer, it managed around 94 MH/s with the Ethash algorithm. The seller said they managed 97.9 on the same card. This is about 64 percent higher than the GeForce RTX 3080 Ti LHR with 12 GB of memory. Both cards use GDDR6X, but this card has a 320-bit bus instead of the 384-bit bus found on the official GeForce RTX 3080 Ti.

The 20GB model of RTX 3080 Ti certainly does sound interesting to many enthusiasts, but unfortunately in this case the card only works in cryptomining. It lacks proper drivers (it is unsupported by the official Game Ready driver). The YouTuber actually tried to learn more about the card, such as finding drivers for this model, but Gigabyte Russia has responded that the company does not have such a model.
