GTC: AI infra goes heterogeneous
NVIDIA’s GTC 2026 pushed a new architecture play: AI stacks are becoming heterogeneous, domain‑specific systems that pair GPUs with high‑speed networking, specialized software, and orchestration blueprints. The company framed networking and physical‑AI blueprints as core growth drivers—networking revenues are reported up 263% year‑over‑year—shifting the debate from ‘more GPUs’ to full infra co‑design.

NVIDIA’s Vera Rubin NVL72 rack combines 72 Rubin GPUs, 36 Vera CPUs, NVLink 6 switching, ConnectX‑9 SuperNICs and BlueField‑4 DPUs in a liquid‑cooled rack‑scale design described on NVIDIA’s product page. (nvidia.com) NVIDIA published the Vera Rubin DSX AI Factory reference design and made the Omniverse DSX digital‑twin blueprint generally available, positioning those artifacts as prescriptive blueprints for data‑center layout, power, cooling and orchestration. (nvidianews.nvidia.com) The DSX reference design lists industrial and engineering partners that include Cadence, Dassault Systèmes, Eaton, Jacobs, Procore, PTC, Schneider Electric, Siemens, Switch, Trane Technologies and Vertiv to validate deployment and operations at gigawatt scale. (datacenterdynamics.com) NVIDIA integrated Groq’s inference technology into the Rubin ecosystem after a transaction valued at roughly $20 billion announced in December 2025, and the company showcased the Groq 3 LPX inference rack as part of its GTC disclosures. (cnbc.com) NVIDIA’s Groq 3 LPX specification page describes each LPX rack as containing 256 LPU accelerators with high SRAM capacity and very high SRAM bandwidth optimized for token‑throughput inference workloads. (nvidia.com) NVIDIA’s SEC filings show multi‑year cloud service agreement commitments of about $26 billion as of October 26, 2025 (updated to roughly $27 billion as of January 25, 2026), and CEO Jensen Huang said at GTC that the company has line‑of‑sight to roughly $1 trillion in orders through 2027 for Blackwell and Vera Rubin systems. (sec.gov) (datacenterdynamics.com) Press coverage and vendor briefings at GTC 2026 reported Vera Rubin NVL72 systems being sold by OEM partners and cited per‑rack price points as high as several million dollars (reports cited figures up to about $8.8 million per NVL72 rack).
