 CPUs do many different types of things, one after the other, sequentially, whereas GPUs are good for parallel processing. They can do multiple parallel things at the same time. And so when you're training AI systems, that parallel processing provides huge increases in speed. Now there's such a shortage of the chips that Nvidia makes called GPUs that there's actually venture capital firms that are not investing dollars in AI startups, they're just giving them the chips because there's such a scramble underway to acquire access to these chips that they're more valuable than dollars in the AI startup space.
