Can RX 9070 16GB run Mixtral-8x7B-Instruct-v0.1?

AMD · 16 GB GDDR6 · 640 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 9070 16GB's 16 GB GDDR6. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 27.0 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.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	27.98 GB	No	29.5 est.
Q4	8K default	29.27 GB	No	27.0 est.
Q4	32K	37.01 GB	No	16.9 est.
FP16	4K	95.69 GB	No	—
FP16	8K default	96.98 GB	No	—
FP16	32K	104.72 GB	No	—

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).
