AlexNet Proved GPU Training Is Viable
srchvrs · x · 2026-07-17
AlexNet (2012) is widely regarded as a defining turning point for deep learning. It proved not only that deep neural networks are effective for vision tasks, but also that training them doesn't require a supercomputer. The post notes that prior to AlexNet, some networks were already trained on GPUs and performed decently in competitions, though they lacked the high profile of ImageNet. In contrast to Google's famous cat classifier, which required 16000 CPUs across 1000 machines, AlexNet demonstrated that competitive training could be achieved with just a single machine and a few GPUs.
