B200 is a genuine architecture change from H100 and H200, not just a memory bump: it's Blackwell rather than Hopper, and its headline capability for inference is native FP4 precision, a 4-bit floating point format neither Hopper-generation card supports. Real-world benchmarks put B200 at roughly 2.5x H100's inference throughput at comparable precision, and 192GB of HBM3e gives even more headroom than H200's 141GB for large models and long context. The tradeoff is real: B200 draws roughly 1,000 watts per GPU against H100 and H200's 700W, which means liquid cooling rather than air, and in several markets B200 supply is genuinely thinner than the established Hopper-generation footprint. Full NVIDIA B200 specs and server configuration options are available on request. H200 and H100 for LLM inference remain the more available, established options for most workloads today, and B300 extends B200's memory ceiling further still for the largest frontier models.
B200 is built on Blackwell rather than Hopper, and the most consequential change for inference is native FP4 precision: a 4-bit floating point format that roughly doubles achievable throughput again over FP8 for models and serving engines built to use it, on top of Blackwell's raw compute advantage over Hopper. Combined, this puts B200 at roughly 2.5x H100's inference throughput at comparable precision. The 192GB of HBM3e, more than H200's 141GB, extends how large a model or how long a context can run on a single card even further than H200 already does. None of this comes free: B200 draws roughly 1,000 watts per GPU against H100 and H200's 700W, requiring liquid cooling rather than air, and that facility requirement is part of why B200 supply genuinely trails H100 and H200 in several markets today as operators retrofit for the higher draw.
B200 inference is placement-sensitive: prompts and responses are often personal data, so jurisdiction matters as much as latency, and B200's power draw makes confirming real in-country supply worth checking. See B200 availability by country below.
