Nvidia's Vera Rubin NVL72 Hits 30x Better Throughput Per Watt Over GB300

Nvidia's Vera Rubin NVL72 systems deliver up to 30x higher throughput per megawatt than the GB300 NVL72. The design pairs Vera CPUs — which manage data flow to prevent memory bottlenecks — with dual-GPU Rubin units connected via an NVLink copper interconnect. Amazon has tripled its Nvidia orders, adding two million GPUs to AWS starting Q3 2026.
