By 2019, GPUs displaced CPUs as the primary training hardware for large-scale commercial cloud AI

Dependents

These beliefs depend on this one:

• IN compute-scaling-drove-dl-revolution — Compute scaling was a major factor in the deep learning revolution: OpenAI measured a 300,000x increase in compute from AlexNet (2012) to AlphaZero (2017), GPUs displaced CPUs as the dominant training hardware by 2019, and AlexNet's GPU-based ImageNet win helped catalyze the modern AI boom. Whether compute scaling was more important than algorithmic innovation is not established by these data points alone.
• IN ml-hardware-diversification-beyond-cpu — ML training hardware has diversified from general-purpose CPUs into at least three specialized architectures — GPUs (parallel matrix ops), TPUs (tensor-optimized ASICs), and neuromorphic chips (memristor-based) — each optimized for different computational patterns.
• IN transformer-gpu-synergy-explains-dominance — Transformer dominance is partly explained by hardware synergy: eliminating sequential recurrence enables massive parallelism, which GPUs — the dominant ML training hardware — are specifically designed to exploit.
