The NVIDIA GB300 NVL72 is a different class ofAI system. Rather than individual servers, it is a fully integrated, liquid-cooled rack that combines 72 Blackwell Ultra GPUs and 36 Grace CPUs intoa single compute domain. The entire rack operates as one unified system, connected by fifth-generation NVLink, and is purpose-built for large-scale AI training, reasoning, and high-throughput inference.
