You don't have to "buy." Fabless as an advantage for AMD is not a story, it is actual history. AMD used to run its own fab and nearly went bankrupt doing so.

You don't have to "buy." Fabless as an advantage for AMD is not a story, it is actual history. AMD used to run its own fab and nearly went bankrupt doing so. It spun off the fab as Global Foundries, and still couldn't catch up due to contractual obligations to use GF which was behind Intel. By eventually switching to TSMC (with new/renegotiated GF contracts; GF still makes glue chips on chiplets and also got some AMD stock), AMD beat Intel with more advanced process (it was already competitive in architecture). Intel is now the one that's disadvantaged by using less than state-of-the-art fabs, the position AMD was in until about 5-7 years ago. Not only is Intel disadvantaged, it's doubling down on fabs, imagining that it will somehow overtake TSMC in the future.
