HGX is a baseboard/platform, not a standalone PCIe graphics card. Complete server CPUs, system RAM, storage, power and cooling are OEM-specific. Sparse Tensor figures require supported structured sparsity.
Published NVIDIA references use different GPU-memory figures: the product overview specifies 2.1 TB, while the latest HGX AI Factory reference architecture specifies eight 288 GB GPUs and 2,304 GB aggregate. Confirm exact installed GPU memory and usable capacity in the OEM quotation.

Ordering the right configurationCompatibility, equipment condition and delivery details
Match the part to its host.
NVIDIA model names identify GPUs and product editions; they do not establish one universal board-vendor part number. Laptop GPUs are supplied within complete laptops. SXM modules, HGX/DGX systems and integrated CPU–GPU platforms require their supported host and interconnect.
Memory type, rank, transfer rate and population rules must match the server and CPU. A storage capacity does not establish NVMe, SATA or SAS compatibility. SSD and mechanical HDD media, firmware, sector format, carriers and security variants need separate checks.
For a precise quotation, send:
- Complete manufacturer/OEM part number and label, including suffix.
- Quantity, acceptable condition and delivery city/country.
- Server, motherboard, CPU or storage-backplane model.
- Application, required configuration and compatibility requirements.
Where a price is not displayed, call or WhatsApp for the current USD price. Confirm equipment condition, quantity, warranty, shipping and dispatch before ordering.
