GPUs have dedicated circuitry for graphics math, and now recently they’re being included with circuitry dedicated for AI math. CPUs do this math using general purpose circuitry which makes them slower at it.
In addition, GPUs have higher total computing power than CPUs. But most tasks are very difficult or impossible to program to run on a GPU or fully utilize it because of the design of GPUs compared to CPUs. Other comments have explained those differences.
AI training and execution happens to take advantage of GPUs well.
