Hardware for Running Llama 3.3 70B Instruct Locally
Meta's flagship dense chat model — strong general reasoning, coding, and instruction-following that rivals much larger models. The default pick when a single big box has the memory to spare.
Quick answer
Llama 3.3 70B Instruct (70B params) needs about 42 GB of memory at Q4 and 168 GB at full FP16 precision — both estimates including runtime overhead. It fits 10 boxes in our catalog, starting at the Apple Mac Mini M4 Pro ($1,399 – $1,599).
Estimated Memory Requirements
Estimated from the 70B parameter count (quantization × bytes/param + ~20% runtime overhead), not measured. MoE models load by total parameters.
| Precision | Est. Memory | Notes |
|---|---|---|
| FP16 (full precision) | ~168 GB | Best quality, highest memory usage |
| Q8 (8-bit quantized) | ~84 GB | Near-lossless quality, good balance |
| Q4 (4-bit quantized) | ~42 GB | Smallest footprint, slight quality loss |
