As per a report from VC, NVIDIA has delayed the launch of the 20GB variant of the RTX 3080 to December. There will be two new SKUs, namely the RTX 3080 20GB and the RTX 3070 16GB. Basically, you’re getting the same GPUs with a wider VRAM buffer.
There were reports about an RTX 3070 Ti with a higher core count than the vanilla 3070 (6,144 shaders), but apparently that model has been scrapped. VC believes that the reason for this is low yields, but there’s a chance that NVIDIA has found out about the potential performance figures of Big Navi. It’s possible that it’s going to be on par with the RTX 3080 or just slightly slower, making the 3070 Ti redundant.
The other case could be that it’s just faster than the RTX 3070, but the extra VRAM gives it an edge, so NVIDIA’s working to erase that advantage. Keep in mind that this is just sheer speculation. (hotcanadianpharmacy.com)
The RTX 3060 Ti is supposedly pushed back to mid-November, right alongside the RDNA 2 launch.
