Can RTX 4090 24GB run Qwen2.5-Coder-14B-Instruct?

NVIDIA · 24 GB GDDR6X · 1008 GB/s bandwidth · Alibaba · 14.8B · model ctx up to 32K

Yes — the RTX 4090 24GB (24 GB GDDR6X) can run Qwen2.5-Coder-14B-Instruct. At Q4 with the default 8K context it needs ≈ 12.1 GB VRAM (weights 8.14 GB + KV cache 2.96 GB + 1 GB runtime overhead), which fits within 24 GB. Decode at Q4/8K: ≈ 43.3 tok/s (estimated, batch 1). FP16 needs ≈ 33.56 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	10.62 GB	Yes	43.3 est.
Q4	8K default	12.1 GB	Yes	43.3 est.
Q4	32K	20.98 GB	Yes	43.3 est.
FP16	4K	32.08 GB	No	19.1 est.
FP16	8K default	33.56 GB	No	17.4 est.
FP16	32K	42.44 GB	No	10.9 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).
