Can RX 7900 GRE 16GB run Qwen3.5-9B?

AMD · 16 GB GDDR6 · 576 GB/s bandwidth · Alibaba · 8.95B · model ctx up to 256K

Yes — the RX 7900 GRE 16GB (16 GB GDDR6) can run Qwen3.5-9B. At Q4 with the default 8K context it needs ≈ 7.71 GB VRAM (weights 4.92 GB + KV cache 1.79 GB + 1 GB runtime overhead), which fits within 16 GB. Decode at Q4/8K: ≈ 41.0 tok/s (estimated, batch 1). FP16 needs ≈ 20.69 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	6.82 GB	Yes	41.0 est.
Q4	8K default	7.71 GB	Yes	41.0 est.
Q4	32K	13.08 GB	Yes	41.0 est.
FP16	4K	19.79 GB	No	21.0 est.
FP16	8K default	20.69 GB	No	19.2 est.
FP16	32K	26.06 GB	No	12.1 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).
