Ian Buck's thesis is about how GPUs can be used as "stream computing": "In this paper (Buck, 2004), we present Brook for GPUs, a system for general-purpose computation on programmable graphics hardware. Brook extends C to include simple data-parallel constructs, enabling the use of the GPU as a streaming co-processor." That's all the point: Apple Silicon allows for running local large language models (and other ML models/algorithms) in a way, at a price point, with enough performance, and so on in which other chips with unified memory don't.
