Intel has always been a two cookie company

Intel sat on 4 cores with exceptionally high power usage for a decade while everyone was screaming for more. This resulted in Apple starting up their own damn chip business, and AMD smashing through the wall with 6, 8, 12, and 16-core chips available to the masses; and core counts requiring a third damn digit if you go server. Furthermore, Intel's process node is woefully behind TSMC's.

Intel sat on their laurels and are getting shat on from all angles now.
