NVIDIA’s RTX 3080 will feature 10GB of GDDR6X memory while the RTX 3090 will be paired with 24GB of 19Gbps VRAM. This is just as I had predicted a few weeks back. Although both the GPUs will be announced on the 1st of September, there’s no word on actual availability.
Furthermore, the source also confirmed that there won’t be any RTX 3080 Ti at launch. As expected, NVIDIA will wait for AMD to show its hand and then launch the Ti to level the playground. Both the RTX 3080 and 3090 are going to feature GDDR6X memory rated at 19Gbps. The former will be paired with a 320-bit bus, the first x80 GPU to move up from a 256-bit interface. The RTX 3090, on the other hand, will come with a 384-bit bus.
It seems that just like the Turing launch, the September 1st event will stick to the basic specs, while the finer architectural details will be unveiled during a press-only event with an NDA.
