Nvidia recently announced its Ampere lineup of Flagship GPUs, the RTX 3090, 3080 and 3070, but we might be getting even faster variants soon. The company did not announce any plans to release the X60 SKU, the mainstream RTX 3060 card, though we have been hearing rumors that Nvidia might release two variants, having the GA106 and GA104 GPU core/board.
The GA104 GPU would likely adopt the Ti or SUPER branding. We expect the GA106 GPU board to be featured on the plain RTX 3060 GPU (non-Ti/SUPER variant), and rumor has it that this card might feature 6 GB of GDDR6 memory over a 192-bit wide bus interface.
The RTX 3060 Ti/Super on the other hand might feature 8 GB of GDDR6 memory over a 256-bit bus interface. Now according to @Kopite7kimi, who is a well known leaker, the RTX 3060 Ti/SUPER GPU would allegedly feature the GA104-200 GPU having 4864 CUDA cores, in a total of 38 SMs, which is 1024 CUDA cores less than the RTX 3070’s 5888 count. The card is also said to feature only 8 GB of GDDR6 memory, since this is more of a successor to the GeForce RTX 2060 SUPER SKU.
The leaker also mentions the following SKUs to release next year, the 3080Ti, RTX 3080 20GB and RTX 3070 Ti/Super 16GB, but the specifications are not yet confirmed to any board partner/AIB. The RTX 3070 SUPER variant is expected to feature the PG142 board, and might come in 8/16 GB VRAM flavors, the non-X GDDR6 memory type. The RTX 3070 Ti on the other hand is expected to feature 16 GB of VRAM. He expects a 6144 CUDA core count for the RTX 3070 Ti/Super.
According to Nvidia’s roadmap we also have the RTX 3080 20 GB GDDR6X VRAM variant in the works. The RTX 3080 20 GB card will feature the same PG133/132 board, having more than 8704 CUDA cores. There is also a rumor regarding an RTX 3080 Ti variant, having either 12 or 16 GB of GDDR6X VRAM. But treat this as a speculation for now, since Nvidia has not given any confirmation on this.
SKU0 GA104-400 PG141/142 GDDR6X/6 8GB 3072=3070Ti
SKU10 GA104-300 GDDR6 2944=3070 https://t.co/p3mfchajfR

But do note that the Ti and SUPER variants might also be the same GPU, since the RTX 3060 is based on the same board, the GA104-200 SKU/ PG142 PCB. Also, don’t expect similar pricing for these Ti or Super variants, since the GeForce RTX 3070 with 16 GB of VRAM could end up close to the pricing of the GeForce RTX 3080, and the RTX 3080 20 GB would cost around $799-$899 USD.
These Ti/Super variants aren’t meant to replace the existing RTX 30 series lineup, but they rather offer a step-up and upgrade in terms of memory and better core specs, but at higher prices. This all depends on how AMD responds back with their NAVI 2X lineup based on the RDNA2 architecture.
