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.
Technical release from major platform (NVIDIA) showing significant performance gains, which will impact AI infrastructure decisions industry-wide.

NVIDIA GPU roadmap: A100 to Vera Rubin (2026)
This article explains NVIDIA's recent data-center GPU roadmap across four major architectures — Ampere (A100), Hopper (H100/H200), Blackwell (B200/B300), and Vera Rubin (R100) — and why each generation matters for AI infrastructure planning. It summarizes memory and interconnect improvements (HBM2e → HBM3/HBM3e → HBM4), precision formats (FP8 and new 4-bit NVFP4), and the move toward rack-scale designs (e.g., NVL72, NVL144). The piece highlights practical procurement implications: match hardware to bottlenecks (memory vs compute), plan facilities for power/cooling, consider renting vs owning, and re-run cost calculations each generation. Vera Rubin (R100) is expected to roll out in H2 2026, followed by Rubin Ultra (2027) and a new architecture codenamed Feynman (2028).
Nvidia's AI Advantage Extends Beyond GPUs
Following its latest earnings, Nvidia’s competitive edge is being reframed as extending beyond GPUs to the broader systems that orchestrate AI workloads. The company is rolling out the Vera Rubin architecture — racks that pair Rubin GPUs with components like the Vera CPU, Groq 3 LPX accelerators, storage and networking — and argues that these systems improve data orchestration and utilization (Nvidia cites up to 3x improvement). Hyperscalers and rival chipmakers (e.g., Amazon, Google, OpenAI’s Jalapeño approach) are pursuing alternative strategies, but the article argues Nvidia currently holds an early lead in system-level efficiency as AI compute scales to gigawatt levels.
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.
