Why it runs well on a Mac

Language models have to sit entirely in memory, and generating each word means reading through them again. Apple Silicon puts up to 512 GB of fast unified memory on one chip that the GPU can use directly, so a model like this fits on one quiet machine instead of a stack of graphics cards.

Qwen3.8 27B is a dense model: all 27 billion parameters are used for every word, so memory bandwidth decides its speed. The M5 Ultra's 1,229 GB/s makes the biggest difference here.
