HGX: the eight GPU baseboard in an OEM chassis
NVIDIA's HGX H200 and HGX B200 baseboards carry eight SXM GPUs on an NVSwitch fabric. An OEM such as Supermicro builds them into a server with CPUs, memory, storage, networking, power and cooling of the buyer's choice. HGX is the way to buy when you want to set the CPU, memory, storage and network configuration yourself, or match an existing fleet. Listed here as the HGX H200 8 GPU system and the HGX B200 8 GPU system, in Supermicro chassis by model number, from five systems.
DGX: NVIDIA's own appliance
DGX H200 and DGX B300 are NVIDIA's complete systems with the CPUs, memory, storage and networking fixed by NVIDIA and NVIDIA's support entitlement bundled. DGX is the way to buy when you want one maker behind the whole box and a known configuration. Listed here by NVIDIA part number, from five systems.
NVL72: the rack as the unit
GB200 NVL72 and GB300 NVL72 are rack scale systems: 36 Grace CPUs and 72 Blackwell or Blackwell Ultra GPUs on one NVLink domain, liquid cooled, with power shelves and NVLink switch trays integrated. NVL72 is the way to buy when the workload wants a single large NVLink domain and the facility has liquid cooling. Listed here as NVIDIA DGX racks by feed direction and as OEM MGX builds, from one rack.
Questions
Can I buy the GPUs alone and build the system myself?
Yes. The H100 SXM5, H200 SXM, B200 SXM and B300 SXM modules are listed on their own pages with published tiers from 20 units, and the interconnect, power and rail parts that go with them are on the same cart.
What is confirmed before invoicing?
The configuration: CPUs, system memory, storage, networking cards and cables, power and cooling options, rails and the software entitlement where the maker bundles one. The confirmation lists each line, typically within 48 hours of checkout, and the invoice follows at the posted range.
Which networking goes with which system?
HGX H200, DGX H200 and HGX B200 pair with ConnectX-7 400G adapters and Quantum-2 InfiniBand or Spectrum-X Ethernet switches. DGX B300 and GB300 NVL72 pair with ConnectX-8. Each system page lists its pairings.
Do racks come ready to power on?
A GB200 or GB300 NVL72 rack ships integrated with its compute trays, NVLink switch trays and power shelves; the in rack coolant distribution unit and the facility connection are confirmed with the configuration.
