Overview

HGX B300 joins eight Blackwell Ultra SXM GPUs through an NVLink 5 switch, giving 14.4 TB/s of total GPU-to-GPU bandwidth. NVIDIA rates the platform at 144 PFLOPS FP4 with sparsity (108 PFLOPS dense) and 72 PFLOPS FP8, with 62 TB/s of aggregate memory bandwidth.

NVIDIA does not sell the baseboard on its own. It ships inside OEM servers that differ in CPU, memory, storage, networking, power and cooling. Send us your preferred OEM and configuration, or your workload and site limits, and we return a written offer with the exact manufacturer SKU and lead time.

Questions about the HGX B300

Can I buy an HGX B300 baseboard on its own?

No. NVIDIA supplies the baseboard to server manufacturers only. We quote complete servers from OEMs such as Supermicro, Dell, HPE, Lenovo, ASUS and Gigabyte.

Air or liquid cooling?

Both exist, depending on the OEM model and GPU power setting. Tell us your rack power and cooling and we will match the system.
