NVIDIA has just confirmed its next-gen Rubin GPU architecture while announcing Rubin & Blackwell GPUs along with the latest Vera CPU.

Blackwell Ultra next year, Rubin in 2026, Rubin Ultra in 2027.
Looks like Rubin, given the name, will be what brings the true next gen gains to game graphics and performance. I suspect that Rubin will use new NV tech that is only found on Rubin cards. RTX 50 to share the same tech with RTX 40 series as expected with nothing new in the way of tech, just more speed.
Seems maybe that there won't be too much of a reason for higher end 40 series gamers to upgrade to 50 series and wait for Rubin.... Maybe.
