can it run
No. 48GB of memory can't hold the 82GB working set this model needs. A smaller quant or a bigger machine is required.
weights 65GB + KV cache 0.28GB at 4k context vs ~48GB usable → no. 65.3 GB vs 48 GB usable — does not fit
computed roofline: 864 GB/s × 0.46–0.76 efficiency window / 9.8GB (Q4_K_M) — bands, never points.
MoE: file is 65GB (that decides fit) but only ~18B of experts activate per token (~9.8GB streamed) — band below is the active-expert estimate, optimistic; community MoE rows run several× the naive bandwidth math
