Can B200 192GB SXM run Mixtral-8x7B-Instruct-v0.1?
NVIDIA · 192 GB HBM3e · 8000 GB/s bandwidth ·
Mistral · 46.7B (active 12.9B) · MoE · model ctx up to 32K
Yes — the B200 192GB SXM (192 GB HBM3e) can run Mixtral-8x7B-Instruct-v0.1. At Q4 with the default 8K context it needs ≈ 29.27 GB VRAM (weights 25.69 GB + KV cache 2.58 GB + 1 GB runtime overhead), which fits within 192 GB. Decode at Q4/8K: ≈ 394.6 tok/s (estimated, batch 1). FP16 (≈ 96.98 GB) also fits, at ≈ 108.5 tok/s (estimated). Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s. Methodology.

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).
