NVIDIA Vera Rubin and NVLink Fusion platform

NVIDIA confirms Vera CPU shipping at scale; AWS receives first Vera CPU server and Vera Rubin GPU; Phoronix finds Vera 10% ahead of AMD EPYC 9575F on geometric mean across permitted workloads

NVIDIA on August 27 announced NVHBM as part of NVLink Fusion, a custom memory architecture that embeds the memory controller in the HBM base die rather than on the XPU die, freeing silicon area for compute. NVHBM delivers up to 30% greater bandwidth and 15% lower power than standard HBM4E while freeing up to 25% more XPU die area. Amazon's Annapurna Labs became the first named partner, committing to support NVHBM in its Trainium4 chips.

The Groq 3 LPX processor uses deterministic compiler scheduling and 128GB of SRAM across the rack to keep decoding delays from compounding across sequential steps in agentic workflows, with preplanned chip-to-chip transfers reducing coordination overhead for small batches. Reporting dated August 26 placed the processor alongside the Vera Rubin NVL72 systems Azure received in August 2026 and NVIDIA's NVLink Fusion platform, citing the Wall Street Journal on agentic AI posing two distinct computing challenges: processing large contexts efficiently and generating tokens with low latency.

Microsoft Azure took delivery of the first production NVIDIA Vera Rubin GPU systems in August 2026, with Microsoft crediting both NVIDIA and its own hardware and datacenter teams, while NVIDIA published benchmark claims that Vera Rubin NVL72 delivers up to 30x higher throughput per megawatt than GB300 NVL72 on agentic workloads, figures NVIDIA states are pending SemiAnalysis review. NVIDIA also announced NVLink Fusion, connecting custom XPUs and CPUs to sixth-generation NVLink with Intel, QCT, Mediatek, and Annapurna Labs as named participants, and Scale-In as the fifth pillar of its AI networking lineup.
