B200, B300 or H200: the buyer's comparison
The three SXM GPUs most datacenter buyers weigh against each other, each sold on its HGX baseboard, on the maker's published figures and on our published prices. The table below is built from the same data as the product pages, so it moves when they move.
What separates them
B300 is the Blackwell Ultra part: more HBM3e per GPU than B200 at the same bandwidth, with a higher power envelope, and it pairs with ConnectX-8 rather than ConnectX-7. B200 is the Blackwell part at the lower price, and it pairs with the ConnectX-7 generation most installed fabrics already run. H200 is the Hopper part with 141 GB of HBM3e, the choice when the software stack, the chassis and the fabric are already Hopper.

Questions
Which one is the lower cost per gigabyte of HBM?
Divide the tier price on the product page by the memory figure in the table. The comparison is on the published figures, and the product pages carry the current tiers.
Do they fit the same baseboard?
No. Each GPU ships on its own HGX baseboard and is sold with it, the H200 SXM on the HGX H200 8 GPU board, the B200 SXM on the HGX B200 8 GPU board and the B300 SXM on the HGX B300 8 GPU board. The system pages list the standard chassis for each.
Which interconnect do I order with each?
H200 and B200 pair with ConnectX-7 400G adapters; B300 pairs with ConnectX-8. The LinkX cables and transceivers on the interconnect page list which adapters they serve.
What is the minimum order?
SXM GPUs are sold on the HGX baseboard, the H200, B200 and B300 from two eight GPU boards each. Smaller quantities are quoted by email, or through the request page.
