AgentX benchmark: Vera Rubin NVL72 delivers 30x efficiency gain over GB300

At the NVIDIA AI Infra Summit, AgentX benchmark results showed the Vera Rubin NVL72 delivers up to 30 times more agent workloads per megawatt than the GB300 NVL72. Measurements were made on early silicon and cover only coding-agent sessions, raising questions about generalizability.

• Vera Rubin NVL72: up to 30x more agent workloads per MW vs GB300 NVL72
• AgentX benchmark measures only coding-agent sessions
• Results obtained on early silicon, not production systems
• Questions raised about benchmark governance independence
