A deep dive into the hardware powering AI, from massive data centers to the phone in your pocket.
The rise of AI didn’t just require better software. It demanded entirely new hardware. Traditional computer chips, while versatile, simply can’t keep up with the billions of calculations modern AI requires. That’s where specialized accelerators come in.
This article extensively explores the four main types of chips that power AI: CPUs, GPUs, NPUs, and TPUs, detailing their distinct characteristics and roles in AI computation. It highlights how each type excels at various tasks, explains the required infrastructure for training and inference, and discusses the challenges associated with each chip. The article also addresses broader trends in AI hardware, including energy efficiency and the growing demand for specialized processors, while reflecting on the future landscape shaped by emerging technologies and market dynamics.
