NVIDIA H800 80GB, AI & Machine Learning Benchmarks & Specs

80GB · AI Score 62.6/100 · anchored estimate vs 51 measured cards

62.6 AI Score Includes estimates

We have not run NVIDIA H800 80GB on our bench. These figures are anchored estimates, interpolated per workload against the 51 GPUs we did measure (confidence: high (sibling silicon)). On Llama 3.1 8B (Q4_K_M) NVIDIA H800 80GB should deliver about 261.8 tokens/sec. Stepping up to Qwen3 32B it should hold roughly 74.1 tok/s. The full Llama 3.3 70B still runs, at about 41 tok/s. For image generation, SDXL should run near 17.29 it/s, and FLUX.1-dev at 4.23 it/s. All 12 workloads fit in 80GB. There is no model in our suite this card has to turn down.

How this estimate is derived. This card hasn’t been through our bench yet, so its numbers are anchored estimates, interpolated from the 51 first-party measured cards (Sibling to measured H100 SXM: identical compute+bandwidth (export SKU, NVLink/FP64 cut, no single-GPU AI impact)). The VRAM “won’t fit” gates are exact, since they’re pure capacity limits. Confidence: high (sibling silicon). Estimates are replaced with measured data as more silicon goes through the bench.
