NVIDIA updates roadmap, with new details on its next-gen GPU 'Feynman' coming in 2028

NVIDIA has updated its data center roadmap for its GPU and CPU lineup at GTC 2026, with the company focused on updating its AI-focused GPU architecture every year. With NVIDIA set to roll out its Vera Rubin architecture and platform this year, which includes the Vera CPU and Rubin GPU, we also got details on its next major GPU architecture, called Feynman, set to arrive in 2028.

The successor to Rubin and 2027's Rubin Ultra, Feynman, will represent a major step for NVIDIA by introducing advanced 3D stacking technology to increase density and improve communication among the various hardware components that power the next generation of AI. In addition, Feynman will be paired with the new Rosa CPU for integrated systems, building on the foundation of Grace in the current Blackwell era.

NVIDIA's roadmap, with Feynman coming in 2028, also lists "custom HBM," which would most likely refer to the next memory evolution beyond HBM4 and HBM4e. We'll have to wait for more details on this new high-bandwidth memory solution. Still, it's safe to assume that its bandwidth and performance will be tailored for increasingly more complex AI models and systems where memory bandwidth and capacity are key.

The arrival of Feynman will also introduce next-gen components and hardware like LP40 memory, BlueField-5 processing, NVLink-8 interconnect technology, and more. This highlights NVIDIA's current focus on delivering a complete AI infrastructure solution, which pairs cutting-edge hardware with its software.

As for Rubin Ultra, which is set to arrive in 2027, NVIDIA showcased the hardware at GTC, with CEO Jensen Huang standing on stage during the opening keynote with a system featuring 1TB of HBM4e memory and a new rack called Kyber that features vertical trays and liquid cooling as standard. The new rack is designed to double the number of GPUs, while upgrading communication to a 7th-generation NVLink switch.
