B200 vs H200

The B200 is a generational change, not a refresh. It uses the Blackwell architecture, pairs two reticle-limited dies that operate as a single GPU, and carries 192 GB of HBM3e with far higher bandwidth than Hopper parts.

The H200 remains a Hopper device with 141 GB of HBM3e. In practice B200 systems deliver considerably more throughput per rack, particularly for low-precision inference formats introduced with Blackwell.

For buyers the decision is rarely purely technical. Blackwell capacity is newer and often supply constrained, while Hopper capacity is broadly available and frequently cheaper per hour. The right question is cost per unit of useful work at your model size, not headline specifications.
