Can I run Gemma 3 27B on a Mac mini 32GB?

Gemma 3 27B at Q4_K_M needs about 20.1 GB, and the Mac mini M6 32GB has 24.0 GB usable. That figure is 32 GB of unified memory on the spec sheet, of which 24.0 GB is usable for weights and cache, at 170 GB/s memory bandwidth. Google’s larger Gemma 3 instruct model, in the same memory band as other mid-20B dense models. These are estimates from our formula, not measured benchmarks.

Memory at each quant

Estimated tokens per second

Estimate: 5–8 tokens/sec at Q4_K_M. This is a bandwidth-derived range, not a bench. Efficiency is a 45–80% unified-memory band from How we calculate.

Context headroom

We do not have a published KV config for this model, so the memory need is the ~4k-context estimate only. Use the VRAM calculator to explore longer chats.
