Rubin is a microarchitecture for graphics processing units by Nvidia.
Microarchitecture
Announced at Computex in Taipei in 2024 by CEO Jensen Huang, it is named after the astrophysicist Vera Rubin and will consist of a GPU named Rubin and a CPU named Vera. The chips will be manufactured by TSMC using a 3 nm process and will use HBM4 memory. It is scheduled for release in Q3 of 2026. Nvidia is using Blackwell GPUs to accelerate the design of Vera, Rubin, and Rubin's successor, Feynman.Rubin is said to have 50 petaflops performance in FP4, increased from 20 petaflops in Blackwell, while Rubin Ultra will double the performance of Rubin with 100 petaflops.
