CPU vs GPU: Why AI Needs Both!
A CPU might have 32 or 64 powerful cores.
A GPU may contain tens of thousands of smaller cores.
CPUs excel at sequential decision making.
GPUs excel at doing the same operation thousands of times simultaneously.
Without CPUs, GPUs don't know what work to execute.
Without GPUs, training modern LLMs would take months instead of days.
