AMD Might have even kept their own fabs... Honestly the damages should see compounded inflation applied.

AMD by the end of the 2000s was beaten and broke. And by 2009 AMD was so down in the dumbs that they settled the lawsuit with Intel on arguably not favorable terms.

We have to remember that Intel went all in on Itanium and it was AMD who made 64bit happen. They absolutely kicked Intels ass on performance and price for quite a while but were not able to leverage that.

So yes, the future would have been quite different.

AMD has been ahead of Intel for the last five years or so but they haven't captured the market share that they likely "deserve". Path dependence and marketing really work.

Is ECC RAM “mainstream” even now?
