NVIDIA GB300 NVL72: Built for the Age of AI Reasoning
The NVIDIA GB300 NVL72 features a fully liquid-cooled, rack-scale design that
unifies 72 NVIDIA Blackwell Ultra GPUs and 36 Arm®-based NVIDIA Grace™
CPUs in a single platform optimized for test-time scaling inference.
AI factories powered with the GB300 NVL72 using NVIDIA Quantum-X800
InfiniBand or Spectrum™-X Ethernet paired with ConnectX®-8 SuperNIC™
provide a 50x higher output for reasoning model inference compared to the
NVIDIA Hopper™ platform.
