CoreWeave Powers Agentic AI, HPC, and Data Analytics Workloads with NVIDIA HGX Rubin NVL8
CoreWeave announced that it is bringing the NVIDIA HGX Rubin NVL8 system to CoreWeave Cloud in the current quarter. The eight-GPU liquid-cooled node features 2 TB of HBM4 memory, 130 TB/s aggregate memory bandwidth, and sixth-generation NVLink to support agentic AI, HPC, and data analytics workloads. The architecture delivers up to 10x higher token throughput than prior architectures and matches training throughput on DeepSeek-R1 using 4x fewer GPUs.
The deployment highlights the rapid commercial rollout of NVIDIA's Vera Rubin generation, offering massive memory bandwidth and density critical for memory-constrained agentic AI and multi-step reasoning workloads.

CoreWeave Brings Up Multi-Rack NVIDIA Vera Rubin NVL72 Cluster
On September 16, 2026, CoreWeave announced the bring up of a multi-rack NVIDIA Vera Rubin NVL72 cluster on CoreWeave Cloud, linking hundreds of NVIDIA Rubin GPUs into a single scale-out cluster for agentic AI. The company also introduced two new CoreWeave AI Object Storage capabilities: cross-region write acceleration and an Archive tier. A single Vera Rubin NVL72 rack pairs 72 Rubin GPUs with 36 Vera CPUs and advanced NVIDIA networking components. CoreWeave positions these capabilities as reducing data-access latency and improving AI training and inference performance.

Rubin NVL72 Agentic Inference: 67x Better Performance per Dollar
SemiAnalysis reports first verified agentic inference results for NVIDIA's Rubin NVL72 platform using their AgentX benchmark. Even on early pre-release software, Rubin delivers up to 67x better performance per dollar of TCO compared to GB300 in certain configurations, and significantly higher throughput per MW. The analysis projects Rubin can generate over 2x more profit per gigawatt than Blackwell, with revenue and profit advantages of 39% and 42% respectively at a fixed power budget. Dynamic power shifting (DSX MaxLPS) allows more GPUs per datacenter footprint. The article highlights Rubin's superiority over H200 and MI355X, with recommendations for inference providers to adopt Rubin for cost-efficient token generation.
