Frequently Asked Questions: Microsoft Phi-4 14B on Apple MacBook Pro/Air (16GB Unified Memory)
How much VRAM does Microsoft Phi-4 14B need on Apple MacBook Pro/Air (16GB Unified Memory)?
At standard 4-bit quantization (Q4_K_M) with 32K context, Microsoft Phi-4 14B requires 13.24 GB of total VRAM (weights + KV cache + CUDA runtime overhead).
What inference speed will Microsoft Phi-4 14B achieve on Apple MacBook Pro/Air (16GB Unified Memory)?
Based on Apple MacBook Pro/Air (16GB Unified Memory)'s 100 GB/s memory bandwidth, expected decode speed is approximately 7 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.
