Nvidia debuts next-generation Vera Rubin superchip at GTC 2025

Nvidia (NVDA) gave the satellite a sneak peek astatine its next-generation Vera Rubin AI superchip during its GTC lawsuit successful San Jose, Calif., connected Tuesday. CEO Jensen Huang took the signifier astatine the SAP Center to amusement disconnected the processor, which volition win the company’s caller Blackwell Ultra spot erstwhile it begins shipping successful the 2nd fractional of 2026.

Vera Rubin, similar the company’s Grace Blackwell superchip, combines a cardinal processing portion and graphics processing unit. In the look of Grace Blackwell, Grace is the CPU and Blackwell is the GPU. For Vera Rubin, Vera is the CPU and Rubin is the GPU.

Nvidia says Vera volition diagnostic 4.2 times the representation recovered successful Grace and 2.4 times the representation bandwidth. Combine that with Vera’s 88 CPU cores and the institution says the spot volition supply 2x the wide show of its predecessor.

Rubin, for its part, volition see 288GB of high-bandwidth representation 4 (HBM4) versus the HBM3e recovered successful the Blackwell Ultra.

Nvidia didn’t halt there, though. The spot elephantine besides debuted the procreation of chips that volition travel aft Vera Rubin called Vera Rubin Ultra. Set to travel to marketplace successful the 2nd fractional of 2027, Nvidia says the Vera Rubin Ultra volition harvester a Vera CPU with its Rubin Ultra chip. And wherever each Rubin processor combines 2 GPUs to signifier a azygous chip, Rubin Ultra combines 4 GPUs.

Like the Blackwell and Blackwell Ultra, Vera Rubin and Vera Rubin Ultra volition beryllium disposable successful a ample server rack system. The Vera Rubin server, called the NVL144, consists of a full of 144 GPUs, and provides 3.3 times the show of the GB300 NVL72.

Then there’s the Vera Rubin Ultra NVL576. Packing 576 Vera Ultra GPUs, Nvidia says the strategy is 14 times faster than the Blackwell Ultra-powered GB300 NVL72. And with 365TB of memory, it’s an implicit monster of a server.

According to Nvidia, the Vera Rubin NVL576 volition beryllium housed successful a caller liquid-cooled server rack plan called the Kyber Rack.

Nvidia’s Blackwell spot is inactive its astir important offering, bringing successful $11 cardinal of the company’s $39.3 cardinal successful full gross successful Q4, but the institution is intelligibly mounting the signifier for Vera Rubin to assistance guarantee its customers and developers are prepared for its next-generation systems.

Vera Rubin and Vera Rubin Ultra volition entreaty to hyperscalers similar Amazon (AMZN), Google (GOOG, GOOGL), Meta (META), and Microsoft (MSFT), arsenic good arsenic probe facilities and governmental organizations moving connected AI services.

But Nvidia’s banal terms has been stung by fears that hyperscalers are overspending connected artificial quality without notching capable returns connected their investments. President Trump’s menace to enact a 25% tariff connected semiconductors produced overseas and the imaginable for further export controls haven’t helped either.
