**Yes.** Gemma 3 27B at Q4\_K\_M needs about 20.1 GB, and the Mac mini M6 32GB has 24.0 GB usable at a \~4k context.

# 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](https://whatcanirunai.vercel.app/method/), not measured benchmarks.

## Memory at each quant

| Quant    | Need vs 24.0 GB | Verdict       |
| -------- | --------------- | ------------- |
| Q4\_K\_M | 20.1 GB         | Q4Fits        |
| Q8\_0    | 34.5 GB         | Q8Won’t fit   |
| FP16     | 64.1 GB         | FP16Won’t fit |

## 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](https://whatcanirunai.vercel.app/method/).

## 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](https://whatcanirunai.vercel.app/vram-calculator/) to explore longer chats.

## What to do instead

* Q8\_0 needs 34.5 GB and does not fit here. The [Mac mini M5 Pro 64GB](https://whatcanirunai.vercel.app/hardware/mac-mini-m5-pro-64/) has 48.0 GB usable, enough for Q8.
* See the [best GPU for this model family](https://whatcanirunai.vercel.app/best-gpu-for/gemma-3/) and the [gemma-3-27b-it model page](https://whatcanirunai.vercel.app/models/gemma-3-27b-it/).
