NVIDIA GB300 NVL72
A fully liquid-cooled rack-scale system that joins 72 Blackwell Ultra GPUs and 36 Grace CPUs into one NVLink domain.
- Type
- Technology
- Where it sits
- The reference rack-scale unit that many cloud and neocloud GPU offerings are built from, so its availability and the racks that house it set what can be rented.
- Constraint
- It is sold as a liquid-cooled rack, so deployment depends on facilities with liquid cooling and high rack power (NVIDIA product page).
What we checked
- NVIDIA states the system combines 72 Blackwell Ultra GPUs and 36 Grace CPUs, with 130 TB/s of NVLink bandwidth across the GPU domain. (source)
- Each GPU gets 800 Gb/s of network connectivity through ConnectX-8 SuperNICs, usable with either Quantum-X800 InfiniBand or Spectrum-X Ethernet. (source)
