A leaker that predicted the specifications of the RTX 3000 series months in advance has just revealed that the company is working on an RTX 3080 Ti. The Twitter user in question has a stellar record and we have no reason to doubt this information. That said, this card does appear to be in very early stages, and considering there are already rumors of NVIDIA dropping the 20 GB variant of the RTX 3080 it might be wise to take this with a grain of salt in case Jensen changes his mind again.

According to Kopite, the RTX 3080 Ti will be based on the GA102 and will have specifications between an RTX 3080 and 3090. The exact chip nomenclature is GA102-250-A1 and will feature a 384 bits bus with GDDR6X memory. The bus-size means NVIDIA will either be using a 12 GB buffer or a 24 GB one. Considering Microsoft Flight Simulator 2020 is already bottlenecked by the 11 GB ram on the RTX 2080 Ti, it would be disappointing to see NVIDIA ship another powerful GPU with a small memory buffer. With RTX IO and asset streaming (Unreal Engine demo for next-generation consoles) becoming a thing in the next year or so, every bit of buffer will help in this paradigm shift.
