NVIDIA DGX B300 (8× B300, 2,304 GB)

10U rackmount AI system featuring eight NVIDIA Blackwell Ultra B300 GPUs on an HGX B300 baseboard, equipped with 2.3 TB of HBM3e memory, dual Intel Xeon 6 processors, up to 4 TB of DDR5, eight ConnectX-8 SuperNICs at 800 Gb/s, and delivering up to 144 PFLOPS of FP4 AI performance.

Designed to train and serve trillion-parameter-class models on a single node as NVIDIA's own reference system, with fifth-generation NVLink and NVSwitch at 1.8 TB/s between GPUs, DGX OS and NVIDIA AI Enterprise preinstalled, and Mission Control for fleet operations when scaled to SuperPOD.

Air-cooled in a standard rack at roughly 14 kW of continuous draw on a three-phase feed, and able to run a 1-trillion-parameter model at FP8 or larger at FP4 entirely in GPU memory.

Price available on request. NVIDIA list has moved above $300,000; OEM 8× B200 boxes list at $490,000, so budget $500,000+.
