Rubin (microarchitecture)
Nvidia microarchitecture From Wikipedia, the free encyclopedia
Rubin is a microarchitecture for 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 Ultra
At Nvidia GTC 2025 it was announced that Rubin will be followed by an improved Rubin Ultra architecture in 2027.[4] It would be in effect two of the Rubin cores connected together.[5]
Performance
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.[5]
