This probably has a lot to do with the anti-consumer segmentation and processor locking that Intel implemented at the dawn of the decade- arbitrary socket changes every 2 years so you couldn't upgrade without buying a new motherboard, and locking overclocking behind a paywall being the two most egregious.

AMD's processors, while not fast, did none of those things and were cheap. I guess that buys you a lot of good will when Intel's still charging 300 dollars for CPUs that wouldn't beat a 2500K at 4.6GHz until several years down the line.
