Can RTX 4070 Super 12GB run Qwen2.5-7B-Instruct?

NVIDIA · 12 GB GDDR6X · 504 GB/s bandwidth · Alibaba · 7.6B · model ctx up to 128K

Yes — the RTX 4070 Super 12GB (12 GB GDDR6X) can run Qwen2.5-7B-Instruct. At Q4 with the default 8K context it needs ≈ 6.7 GB VRAM (weights 4.18 GB + KV cache 1.52 GB + 1 GB runtime overhead), which fits within 12 GB. Decode at Q4/8K: ≈ 42.2 tok/s (estimated, batch 1). FP16 needs ≈ 17.72 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	5.94 GB	Yes	42.2 est.
Q4	8K default	6.7 GB	Yes	42.2 est.
Q4	32K	11.26 GB	Yes	42.2 est.
FP16	4K	16.96 GB	No	16.6 est.
FP16	8K default	17.72 GB	No	15.2 est.
FP16	32K	22.28 GB	No	9.6 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).
