ROCM

Yes — the Ryzen AI Max 390 64GB (48 GB LPDDR5X) 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 48 GB. Decode at Q4/8K: ≈ 10.0 tok/s (estimated, batch 1). FP16 (≈ 31.14 GB) also fits, at ≈ 2.7 tok/s (estimated). Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s.

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).
