can it run

Can the Radeon Vega 3 (iGPU) run gpt-oss 20B MoE?

NO

14.2 GB vs 5.5 GB usable — does not fit

~5.5GB usable · GCN5.1 (iGPU) · model file 14GB · 20B MoE

~4.6–15 tok/s (active-expert estimate)

computed roofline: 38.4 GB/s × 0.25–0.80 efficiency window / 2.1GB (Q4_K_M) — bands, never points.

MoE: file is 14GB (that decides fit) but only ~3B of experts activate per token (~2.1GB streamed) — band below is the active-expert estimate, optimistic; community MoE rows run several× the naive bandwidth math
