ROCM

Yes — the Ryzen AI Max 390 64GB (48 GB LPDDR5X) 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 48 GB. Decode at Q4/8K: ≈ 18.0 tok/s (estimated, batch 1). FP16 (≈ 17.72 GB) also fits, at ≈ 5.0 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	5.94 GB	Yes	18.0 est.
Q4	8K default	6.7 GB	Yes	18.0 est.
Q4	32K	11.26 GB	Yes	18.0 est.
FP16	4K	16.96 GB	Yes	5.0 est.
FP16	8K default	17.72 GB	Yes	5.0 est.
FP16	32K	22.28 GB	Yes	5.0 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).
