At this point, AMD has released three graphics cards based on the Navi 21 GPU: the Radeon RX 6800, the RX 6800 XT, and the RX 6900 XT. All of them use 16GB of GDDR6 memory, but surprisingly, a listing of a Navi 21-based graphics card with 8GB has recently been spotted in a benchmark database, indicating a new, unannounced SKU.
Found by @KOMACHI_ENSAKA, the Userbenchmark listing shows that someone tested an AMD Radeon graphics card with 8GB using the Navi 21 GPU. Until now, we haven’t heard anything about such a card and AMD has not announced a GPU with this specification, leading to speculation on a new SKU.

Performance-wise, the card looks to be placed between the Radeon RX 6800 and the RX 6700 XT, but compared to Nvidia’s graphics cards, the benchmark suggests it performs on par with the RTX 3060 Ti.
There are many theories about this GPU already. Some think it’s a prototype, while others believe it’s a new GPU coming out soon. However, the latter seems a bit strange from a market point of view. Based on Nvidia and AMD MSRPs, the Radeon RX 6700 XT is battling the RTX 3070, and the RX 6800 is going against the RTX 3070 Ti, leaving little room for another Navi 21-based RX 6000 card in the line-up
