Architecture & Throughput Transparency: Single-user decode speed (~0 tok/s) is memory-bandwidth bound at batch size = 1 on Apple MacBook Pro M4 Pro (24GB Unified Memory) (273 GB/s). Prompt prefill / TTFT (~0 tok/s) is compute-bound and utilizes GPU Tensor cores. Actual latency varies with FlashAttention-2 and runtime engine (Ollama/vLLM/llama.cpp).

FAQ & Reference

Frequently Asked Questions: Qwen 2.5 72B Instruct on Apple MacBook Pro M4 Pro (24GB Unified Memory)

How much VRAM does Qwen 2.5 72B Instruct need on Apple MacBook Pro M4 Pro (24GB 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 MacBook Pro M4 Pro (24GB Unified Memory)?

Based on Apple MacBook Pro M4 Pro (24GB Unified Memory)'s 273 GB/s memory bandwidth, expected decode speed is approximately 0 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.
