According to one reliable source over at Igor’s Lab, it is being predicted that Nvidia might be planning to release at least three different SKU variants of the RTX 3000 series of Ampere cards. Some rumored specs were also shared by one twitter user kopite7kimi before, but I suggest you to take this leak with a huge ‘grain of salt’.
These are unconfirmed rumors. As of now Nvidia has made no official announcement on this, though the above sources have posted reliable information in the past. According to Igor’s lab, NVIDIA plans to release at least three variants in the RTX 3000 series lineup, the vanilla RTX 3080, RTX 3080 (Ti/Super), and the RTX 3090 (Ti/Super). Once again we are not fully sure about the nomenclature.
But we do have some info on the board type, GPU chip name, as well as Memory type. All three variants are based on the same ‘PG132’ board/PCB, and they are different bins of the same “GA102” chip. These are going to feature the GDDR6X memory type, and will support a 300+ bus width interface.
Some photos of the upcoming RTX 3080 card were shared on the web recently, and now we expect this SKU to feature a 320-bit bus width along with 10 GB GDDR6X VRAM, and a 320W TDP value.
The other SKU the RTX 3080 Ti/Super should end up with a 352-bit wide bus width, having 11GB GDDR6X of VRAM, and a 320W TDP value. But 11 GB of VRAM does not make much sense though, coming from a 10 GB non-Ti variant. I doubt Nvidia will follow this strategy. Even the TDP is same.
The flagship SKU, the RTX 3090, on the other hand will end up with 24 GB of GDDR6X double-sided vRAM, on a 384-bit bus width, and will have a 350W TDP. All GPUs will feature 3x Display Ports and HDMI connectors, and the flagship RTX 3090 GPU might support NVLink as well.
We don’t for sure whether the RTX 3090 would be a direct replacement of the TITAN GPU, since these are unconfirmed leaks. Sure, this GPU supports NVLINK and has double the VRAM, but this doesn’t confirm whether Nvidia plans to drop the TITAN nomenclature. Though, current-gen TITAN already carries the RTX branding/nomenclature. Only time will tell whether these SKUs and the specs are indeed real.
