MoE Offloading Performance Varies on Consumer GPUs

A local language model enthusiast explored the performance of Mixture-of-Experts (MoE) models on a 16GB VRAM GPU, comparing traditional layer offloading with a newer MoE-specific offloading technique. The experiment involved testing five different MoE models using llama.cpp on an Acer Predator laptop with an NVIDIA RTX 4090 Laptop GPU and an Intel Core i9-14900HX CPU. Contrary to expectations, the results indicated that selective MoE offloading did not consistently outperform traditional layer offloading, prompting further investigation into the nuances of these methods for optimizing local LLM performance.
