Why It Mattered

B200 belongs to the Blackwell data-center generation, where the important context is large-scale AI infrastructure, memory capacity, interconnect, and system integration. Separating it from the broad NVIDIA B-Series label keeps future server variants clear.

Used-Market Caution

Before buying used, confirm PCIe versus SXM or OAM form factor, passive airflow needs, auxiliary power, HBM size, firmware locks, ECC or retired-page errors, seller proof from nvidia-smi under load, and whether any vGPU or enterprise licensing is required.
