AlexNet Proved GPU Training Is More Efficient

prajdabre · x · 2026-07-17

This post reflects on the significance of AlexNet (2012): it proved that deep neural networks work and that supercomputers aren't strictly necessary for deep learning—a few GPU chips are enough.

The author contrasts this with Google's early cat classifier, which required a cluster of 16000 CPUs across 1000 machines. AlexNet marked a fundamental shift in the computing paradigm for deep learning training by 2012.
