Rubin is a microarchitecture for graphics processing units (GPUs) by Nvidia.
Announced at Computex in Taipei in 2024 by CEO Jensen Huang, it is named after 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 mass production in late 2025 and will be available for purchase in early 2026. [1] [2] Nvidia is using its own Blackwell GPUs to accelerate the design of Vera and Rubin, as well as Rubin's successor, Feynman. [3]
Rubin is stated to have 50 petaflops performance in FP4 (4-bit floating point math, often used for AI), increased from 20 petaflops in Blackwell, while Rubin Ultra will double the performance of Rubin with 100 petaflops. [4]
At Nvidia GTC 2025 it was announced that Rubin will be followed by an improved Rubin Ultra architecture in 2027. [5] It would be in effect two of the Rubin cores connected together. [4]
