Can RX 9070 16GB run Qwen2.5-72B-Instruct?

AMD · 16 GB GDDR6 · 640 GB/s bandwidth · Alibaba · 72.7B · model ctx up to 128K

No — Qwen2.5-72B-Instruct at Q4 needs ≈ 48.26 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: ≈ 1.3 tok/s (estimated, batch 1). FP16 needs ≈ 160.94 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	48.26 GB	No	1.8 est.
Q4	8K default	55.53 GB	No	1.3 est.
Q4	32K	99.15 GB	No	—
FP16	4K	153.67 GB	No	—
FP16	8K default	160.94 GB	No	—
FP16	32K	204.56 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).
