GPU Fit Matrix
Can the Mac mini M4 Pro (64GB) run Gemma 4 31B?
Yes — fits at FP8
Planning estimate: Gemma 4 31B (31B total) needs about33.5 GB of VRAM at FP8(≈4K context). The Mac mini M4 Pro (64GB) has64 GB.
This is a computed planning estimate (parameter count × bytes/parameter × quantization + context overhead), not a measured benchmark. See how we estimate.
VRAM needed by quantization
| Quantization | Est. VRAM needed | Fits 64GB? |
|---|---|---|
| BF16 | 64.5 GB | ❌ No |
| FP8 | 33.5 GB | ✅ Yes |
No measured benchmark yet. We don't publish invented tokens/sec — when we have a first-party measured run for this pairing, it will appear here. For now this page is a VRAM planning estimate. Model the exact case in ourVRAM calculator.
