Frequently Asked Questions: Qwen 2.5 Coder 32B Instruct on Apple Mac Studio M4 Max (128GB Unified Memory)
How much VRAM does Qwen 2.5 Coder 32B Instruct need on Apple Mac Studio M4 Max (128GB Unified Memory)?
At standard 4-bit quantization (Q4_K_M) with 32K context, Qwen 2.5 Coder 32B Instruct requires 25.22 GB of total VRAM (weights + KV cache + CUDA runtime overhead).
What inference speed will Qwen 2.5 Coder 32B Instruct achieve on Apple Mac Studio M4 Max (128GB Unified Memory)?
Based on Apple Mac Studio M4 Max (128GB Unified Memory)'s 546 GB/s memory bandwidth, expected decode speed is approximately 17 tokens per second.
Can I expand context beyond 32K tokens?
Each additional 32K tokens of context requires additional KV cache memory. For longer context windows, consider 8-bit or 4-bit KV cache quantization.
