can it run

Can the GTX 1660 Ti Mobile run gpt-oss 20B MoE?

NO

14.2 GB vs 6 GB usable — does not fit

6GB · Turing TU116 · model file 14GB · 20B MoE

~66–99 tok/s (active-expert estimate)

computed roofline: 288 GB/s × 0.48–0.72 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
