Lab Report: Benchmarking Qwen 2.5 Coder 32B on Apple Mac Studio M3 Max
In-depth testing of token generation throughput, memory pressure, and 32k context retention for local AI coding assistants.
Apple Silicon unified memory delivers 32 tokens/second on 32B quantized models with zero fan noise, proving viable for 100% private developer environments.
Verified Facts & Data
- Qwen 2.5 Coder 32B Q4_K_M runs at 31.8 tokens/sec using Ollama and Metal acceleration.
- Memory footprint stabilized at 21.4 GB unified RAM.
- Zero quality degradation observed compared to unquantized FP16 weights on standard HumanEval tests.
Strategic Implications
For security-conscious teams with confidential IP, a $4,000 Mac Studio hardware investment pays for itself within 6 months compared to cloud API subscription tiers.
We stress-tested Qwen 2.5 Coder 32B across 1,000 programming challenges to evaluate whether local inference can truly replace cloud APIs for everyday software engineering.
Performance Metrics
- Prompt Evaluation (Time-to-First-Token): 120ms (at 4k context)
- Generation Speed: 31.8 tokens/second
- Peak Thermal Throttle: None (Mac Studio stayed under 48°C)
- Power Consumption: 68W under continuous load
The current sweet spot for private local engineering assistants.
