Gemma 2 27B needs 16 GB VRAM at Q4. The Mac Studio M4 Max 128GB has 128 GB.
💎 Gemma 2 27B (Google) is a 27B-parameter model for high-quality chat, reasoning, analysis. Best quality under 24GB at Q4 — punches above its weight. The question is whether the Mac Studio M4 Max 128GB’s 128 GB of VRAM can hold it — here’s the exact math.
VRAM requirements
| Quantization | VRAM needed | Mac Studio M4 Max 128GB |
|---|---|---|
| Q4_K_M (recommended) | 16 GB | ✅ |
| Q8_0 (near-lossless) | 28 GB | ✅ |
Expected performance
Running Gemma 2 27B at Q4 on the Mac Studio M4 Max 128GB, expect roughly ~16 tokens/sec in Ollama or llama.cpp — comfortably faster than reading speed, so chat feels responsive.
Headroom: 16 GB used of 128 GB leaves about 112 GB free for KV cache (context). That’s fine for 4-8K context; for 32K+ you may need a smaller batch or a lower quant.

Frequently asked questions
Can the Mac Studio M4 Max 128GB run Gemma 2 27B?
Yes — runs at Q4 and full Q8 quality. Gemma 2 27B needs 16 GB VRAM at Q4_K_M; the Mac Studio M4 Max 128GB has 128 GB.
How much VRAM does Gemma 2 27B need?
Gemma 2 27B needs about 16 GB at Q4_K_M (recommended) and 28 GB at Q8_0.
How many tokens per second will the Mac Studio M4 Max 128GB get on Gemma 2 27B?
Roughly ~16 tokens/sec at Q4 in Ollama or llama.cpp.
About the speed figure. The tokens/sec number above is an estimate, not a measured benchmark. Real throughput depends on your runtime and backend (Ollama, llama.cpp, vLLM), the exact quantization you download, context length, memory bandwidth, and whether any layers are offloaded to CPU. Treat it as a rough guide to the tier of performance, not a promised result.
