Architecture & Throughput Transparency: Single-user decode speed (~0 tok/s) is memory-bandwidth bound at batch size = 1 on Apple MacBook Pro/Air M1 (8GB Unified Memory) (68 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 3.8 27B Instruct on Apple MacBook Pro/Air M1 (8GB Unified Memory)

How much VRAM does Qwen 3.8 27B Instruct need on Apple MacBook Pro/Air M1 (8GB Unified Memory)?

At standard 4-bit quantization (Q4_K_M) with 32K context, Qwen 3.8 27B Instruct requires 21.93 GB of total VRAM (weights + KV cache + CUDA runtime overhead).

What inference speed will Qwen 3.8 27B Instruct achieve on Apple MacBook Pro/Air M1 (8GB Unified Memory)?

Based on Apple MacBook Pro/Air M1 (8GB Unified Memory)'s 68 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.
