2026年Mac:统一内存和带宽决定本地LLM性能

在2026年,Mac硬件上本地运行大型语言模型将主要取决于统一内存容量和带宽,而非核心数量。拥有16GB统一内存的Mac可以很好地运行多达140亿参数的模型,而对于70B级别模型建议使用64GB,对于超过1000亿参数的模型则需要128GB或更多。内存带宽是生成速度的主要决定因素,M4等新芯片比旧芯片具有显著优势。OllamaLM Studio、MLX和llama.cpp等工具提供了在本地运行这些模型的不同接口和功能。 AI

影响 随着Apple Silicon等芯片在内存容量和带宽方面的改进,在消费级硬件上本地部署LLM将变得越来越可行。
