Yes — the Mac Studio M3 Ultra 96GB (96 GB LPDDR5) 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 96 GB. Decode at Q4/8K: ≈ 40.4 tok/s (estimated, batch 1). FP16 needs ≈ 96.98 GB — does not fit on this card. 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).
