Rumour | NVIDIA GeForce RTX 3090 Ampere GPU to sport 4,992 CUDA cores and 12 GB of 18 Gbps VRAM

Treat this with some scepticism for the time being. While most of the details contained herein are from @kopite7kimi, a reliable leaker of information about upcoming NVIDIA hardware, we have been unable to verify them.

In line with previous rumours about the Ampere architecture, @kopite7kimi claims that NVIDIA is developing a GPU codenamed the GA102. Referred to as the RTX 3090 for simplicities sake, other information about the GA102 suggests that it will find its way into multiple GPUs.

At any rate, @kopite7kimi claims that the RTX 3090 would be the "full-fat" GA102. However, they do state that the card will feature 4,992 CUDA cores, a way of previous estimates. Apparently, the card will feature 39 Texture Processing Clusters (TPCs) too, which would be three more clusters than the full TU102 configuration has. 

Referred to as "THE ULTIMATE GEFORCE" by @Ragdoll_Kitties, the GA102 is said to include 12 GB of GDDR6 VRAM running at 18 Gbps. Apparently due to arrive by "August or later", this ties in with previous rumours about consumer Ampere GPUs slipping to Q3 or Q4 2020.

However, Ampere is also said to be based on a 10 nm process. Hence, it is no longer necessarily clear what performance levels to expect from the upcoming architecture. If true, then AMD could have a big advantage over NVIDIA headed into the next-generation mainstream desktop GPUs.
