Question 1

What is the total GPU memory of the NVIDIA GB300 NVL72?

Accepted Answer

The GB300 NVL72 provides up to 21TB of HBM3e memory across 72 NVIDIA B300 GPUs, with each GPU carrying 288GB of HBM3e.

Question 2

How many CPUs does the GB300 NVL72 rack include?

Accepted Answer

The rack includes 36 NVIDIA Grace CPUs, delivered through 18 NVIDIA GB300 Grace Blackwell Superchips at 2 Grace CPUs per Superchip.

Question 3

What is the GPU-to-GPU interconnect bandwidth on the GB300 NVL72?

Accepted Answer

NVLink switches provide 1.8TB/s GPU-to-GPU interconnect bandwidth across all 72 GPUs in the rack.

Question 4

Is the NVIDIA GB300 NVL72 compatible with InfiniBand networking?

Accepted Answer

Yes. It supports NVIDIA Quantum-X800 InfiniBand and NVIDIA Spectrum-X Ethernet, both delivering up to 800Gb/s compute fabric with ConnectX-8 SuperNICs.

Question 5

What storage options does the GB300 NVL72 support?

Accepted Answer

The rack supports up to 144 E1.S PCIe 5.0 drive bays, enabling high-throughput local NVMe storage for data-intensive AI pipelines.

Question 6

NVIDIA GB300 NVL72 vs NVIDIA HGX H100 — which is better for LLM training?

Accepted Answer

The GB300 NVL72 offers far greater memory capacity (21TB vs ~640GB), wider NVLink bandwidth (1.8TB/s), and a newer Blackwell Ultra architecture — making it significantly more capable for frontier LLM training at rack scale.

Question 7

Can the GB300 NVL72 support multi-rack liquid cooling?

Accepted Answer

Yes. The in-row CDU option scales up to 1.8MW, supporting up to 8 racks from a single cooling unit with N+1 pump redundancy.

Question 8

What power does the NVIDIA GB300 NVL72 consume?

Accepted Answer

Total rack power is 132kW, supplied by 8x 1U 33kW power shelves, each with 6x 5.5kW PSUs in a redundant configuration.
