Can RX 7600 XT 16GB run Mixtral-8x7B-Instruct-v0.1?
AMD · 16 GB GDDR6 · 288 GB/s bandwidth ·
Mistral · 46.7B (active 12.9B) · MoE · model ctx up to 32K
No — Mixtral-8x7B-Instruct-v0.1 at Q4 needs ≈ 27.98 GB even at 4K context, beyond the RX 7600 XT 16GB's 16 GB GDDR6. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 12.1 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. 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).
