I think AMD, Intel, and Nvidia target for different kinds of customers.

But having competition is still a good thing for all customers, as these main manufacturers continue to improve their chips.

While you're right about Intel and Nvidia, AMD makes both processors as well as GPUs so It can be compared with both of them, basically during the past decade Nvidia has been known to be the king in the graphics department(and they still are), and Intel in the CPU department, but AMD is introducing new products that has brought about an interesting twist in both of the aforementioned markets
