NVIDIA took the Hot Chips 2026 stage to detail the Rubin GPU, its next data center accelerator in the Vera Rubin platform. Agentic AI is the recurring theme, and NVIDIA argues it changes not just the tensor core but the entire compute, networking, power, and serviceability stack around it. It feels like we know a lot about Vera, but let us see what NVIDIA has for Hot Chips.

NVIDIA Rubin GPU at Hot Chips 2026
NVIDIA is talking about agentic AI is the most complex workload it has ever targeted. They did earlier in its Vera talk as well. It strings together observation, reasoning, and action across LLMs, CPUs, DPUs, orchestration, security, memory, and networking. That breadth is the reason the whole platform gets redesigned, not just the silicon.
Vera Rubin is presented as a full-stack AI factory platform spanning seven chips and five racks. NVIDIA folds in the Vera CPU, the Rubin GPU, BlueField-4, Spectrum-6, and even Groq LPUs, with storage, networking, tool call, and sandbox support layered on top. Agentic AI needs all of that surface area, from context and memory to the scale-out fabric.
