Current NVIDIA specifications distinguish 252 GB GPU HBM3e from 496 GB CPU LPDDR5X. Earlier 784 GB marketing references must not be treated as the specification of every current OEM system. Additional RTX PRO GPU/ports vary by OEM. Sparse Tensor rates require supported structured sparsity.

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.
