Frequently Asked Questions: Qwen 2.5 Coder 7B Instruct on Apple Mac Studio M3 Ultra (256GB Unified Memory)
How much VRAM does Qwen 2.5 Coder 7B Instruct need on Apple Mac Studio M3 Ultra (256GB Unified Memory)?
At standard 4-bit quantization (Q4_K_M) with 32K context, Qwen 2.5 Coder 7B Instruct requires 6.41 GB of total VRAM (weights + KV cache + CUDA runtime overhead).
What inference speed will Qwen 2.5 Coder 7B Instruct achieve on Apple Mac Studio M3 Ultra (256GB Unified Memory)?
Based on Apple Mac Studio M3 Ultra (256GB Unified Memory)'s 819 GB/s memory bandwidth, expected decode speed is approximately 109 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.
