NVIDIA H200 vs B200

A generational decision. The H200 is proven, air-coolable Hopper you can deploy today; the B200 is Blackwell — roughly 2.5× the FP8 throughput, 192GB HBM3e at 8 TB/s and 1.8 TB/s NVLink, but higher power and mandatory direct liquid cooling. Here is which fits.

Which should you choose?

The decision comes down to workload, facility and timeline. Here is the call by scenario.

B200Frontier training & large-scale inference

About 2.5× the FP8 throughput, 8 TB/s memory bandwidth and native FP4 make it the engine for the largest training runs and highest-throughput serving — in a liquid-cooled hall.

H200Near-term & air-cooled capacity

Available now, 700W, and drops into H100/H200 air- or liquid-cooled infrastructure. The lower-risk path when you need capacity this quarter or the facility is not DLC-ready.

H200Brownfield & mixed fleets

Reuses existing Hopper servers, cooling and power designs. Choose the B200 when you are building greenfield liquid-cooled capacity and want the longest useful life.

H200 vs B200, answered

How much faster is the B200 than the H200?

For compute, the B200 delivers roughly 2.5× the FP8 tensor throughput of the H200 and adds native FP4 for inference, plus 8 TB/s memory bandwidth versus 4.8 TB/s. Real gains depend on the workload, but Blackwell is a clear generational step up.

Does the B200 need liquid cooling and the H200 not?

The B200 runs ~1,000W (up to ~1,200W) and is deployed with direct-to-chip liquid cooling. The H200 stays at 700W and can be air-cooled, so it fits facilities that are not yet DLC-ready.

Should I buy the H200 now or wait for the B200?

Buy the H200 for capacity you need now, air-cooled halls, or to extend a Hopper fleet. Choose the B200 when you are building liquid-cooled greenfield capacity and want maximum training throughput and the longest useful life.
