💎 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.
