“AMD had the Athlon 64 put ahead of everything Intel had available and they were making tons of money off its sales. But then, suddenly, sales went dry and benchmarks began to run better on Intel despite real world deltas being much smaller than synthetics reflected.
“Can you guess why? Because Intel paid PC manufacturers out of its own pocket for years to not buy AMD’s chips.
“Although they were faster, manufacturers went with the bribe because the amount they made from that outweighed the amount they get from happy customers buying their powerful computers. And thus, the industry began to stagnate a bit with CPUs not really moving forward as quickly. T
“They also attacked all existing AMD chips by sabotaging their compiler, making it intentionally run slower on all existing and future AMD chips. Not just temporarily, but permanently; all versions of software created with that version of the compiler will forever run worse on AMD chips, even in 2020 (and yes, some benchmark tools infected with it are still used today!).”
