Can Arc B580 12GB run Qwen3-1.7B?

Intel · 12 GB GDDR6 · 456 GB/s bandwidth · Alibaba · 2.0B · model ctx up to 40K

Yes — the Arc B580 12GB (12 GB GDDR6) can run Qwen3-1.7B. At Q4 with the default 8K context it needs ≈ 2.5 GB VRAM (weights 1.1 GB + KV cache 0.4 GB + 1 GB runtime overhead), which fits within 12 GB. Decode at Q4/8K: ≈ 145.1 tok/s (estimated, batch 1). FP16 (≈ 5.4 GB) also fits, at ≈ 39.9 tok/s (estimated). 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	2.3 GB	Yes	145.1 est.
Q4	8K default	2.5 GB	Yes	145.1 est.
Q4	32K	3.7 GB	Yes	145.1 est.
FP16	4K	5.2 GB	Yes	39.9 est.
FP16	8K default	5.4 GB	Yes	39.9 est.
FP16	32K	6.6 GB	Yes	39.9 est.

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).
