LLM Hardware Choice: Bandwidth Over RAM Capacity, Argues Towards AI

This article argues that for running large language models (LLMs) locally, memory bandwidth is a more critical factor than RAM capacity. It suggests that Apple's M-series chips, while offering high RAM capacity, may not be optimal for LLMs due to their memory architecture. The author introduces the concept of 'Modality Aware Capacity Scaling' as a framework for evaluating hardware for AI workloads, emphasizing the importance of efficient data transfer between the CPU, GPU, and memory. AI

IMPACT Suggests a shift in hardware purchasing criteria for AI practitioners, prioritizing memory bandwidth for local LLM inference.
