ROCM

Yes — the RX 7800 XT 16GB (16 GB GDDR6) can run OLMo-2-1124-13B-Instruct. At Q4 with the default 8K context it needs ≈ 11.28 GB VRAM (weights 7.54 GB + KV cache 2.74 GB + 1 GB runtime overhead), which fits within 16 GB. Decode at Q4/8K: ≈ 29.0 tok/s (estimated, batch 1). FP16 needs ≈ 31.14 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.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	9.91 GB	Yes	29.0 ± est.
Q4	8K default	11.28 GB	Yes	29.0 ± est.
Q4	32K	19.5 GB	No	55.6 ± est.
FP16	4K	29.77 GB	No	6.6 ± est.
FP16	8K default	31.14 GB	No	6.0 ± est.
FP16	32K	39.36 GB	No	3.8 ± 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).
