Can H200 141GB SXM5 run DeepSeek-R1-0528-Qwen3-8B?
NVIDIA · 141 GB HBM3e · 4800 GB/s bandwidth ·
DeepSeek · 8.2B · model ctx up to 128K
Yes — the H200 141GB SXM5 (141 GB HBM3e) can run DeepSeek-R1-0528-Qwen3-8B. At Q4 with the default 8K context it needs ≈ 7.15 GB VRAM (weights 4.51 GB + KV cache 1.64 GB + 1 GB runtime overhead), which fits within 141 GB. Decode at Q4/8K: ≈ 372.5 tok/s (estimated, batch 1). FP16 (≈ 19.04 GB) also fits, at ≈ 102.4 tok/s (estimated). Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s.

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured
anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s
means the model is far beyond this card (offload-only territory).
