Can Arc A770 16GB run Magistral-Small-2509?

Intel · 16 GB GDDR6 · 560 GB/s bandwidth · Mistral · 24.0B · model ctx up to 128K

No — Magistral-Small-2509 at Q4 needs ≈ 16.6 GB even at 4K context, beyond the Arc A770 16GB's 16 GB GDDR6. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 30.1 tok/s (estimated, batch 1). FP16 needs ≈ 53.8 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	16.6 GB	No	39.4 est.
Q4	8K default	19.0 GB	No	30.1 est.
Q4	32K	33.4 GB	No	9.7 est.
FP16	4K	51.4 GB	No	1.1 est.
FP16	8K default	53.8 GB	No	1.0 est.
FP16	32K	68.2 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).
