A few weeks back, we saw the NVIDIA GeForce RTX 3080 Ti 20 GB custom models listed in Russia. It can now be confirmed that these cards are indeed real and several of them shipped in the graphics retail segment a while back.

The NVIDIA GeForce RTX 3080 Ti 20 GB graphics card was one of the many configurations that the card was rumored to get but it ended up getting 12 GB GDDR6X memory instead. However, it looks like manufacturers did end up making 20 GB variants of the GeForce RTX 3080 Ti which have now shown up at the Russian hardware store, Hardvar (via Yandex.Ru).
