Kopite7kimi, who we know for its accurate hardware leaks and who has provided updates to these various specifications.

According to its latest update, the GeForce RTX 4080 could get 23 Gbps GDDR6X memory faster. This is, of course, an upgrade from the previous spec list, with the memory set to 21 Gbps.
