Before AI, a human would think about what to do and then take action on their computer screen. Today the GPU plans the action by writing tokens, and the CPU executes it by writing code.

The workflow a lot of people can relate to is pulling data, analyzing it, and displaying a chart. Every single one of those steps can now be done by an agent using a computer driven by a CPU. That is massive CPU demand, because agents can move faster, longer, and deeper than a human possibly could.

Before, you had to click, read, and plan a task yourself. Now an agent runs that same sequence in a loop. The GPU decides the next move, the CPU carries it out, and the cycle repeats. Every cycle is a GPU-to-CPU round trip.
