Can RTX 4070 Super 12GB run Mistral-Small-4-119B-2603?
NVIDIA · 12 GB GDDR6X · 504 GB/s bandwidth ·
Mistral · 119.0B (active 6.5B) · MoE · model ctx up to 256K
No — Mistral-Small-4-119B-2603 at Q4 needs ≈ 67.1 GB even at 4K context, beyond the RTX 4070 Super 12GB's 12 GB GDDR6X. It would only run with heavy CPU/disk offload. FP16 needs ≈ 240.3 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).
