Nvidia may introduce an RTX 3090 Super later this year to probably counter Intel's upcoming Xe-HPG Alchemist GPU launch in early 2022. The RTX 3090 Super is expected to be based on the GA102 core and will feature 10,752 CUDA cores and a higher 400 W+ TDP. Other specifications are not yet available.
