Frequently Asked Questions: Qwen 2.5 72B Instruct on Apple Mac Studio M4 Max (128GB Unified Memory)
How much VRAM does Qwen 2.5 72B 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 72B Instruct requires 51.27 GB of total VRAM (weights + KV cache + CUDA runtime overhead).
What inference speed will Qwen 2.5 72B 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 8 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.
