Duh, of course Nvidia & AMD are shut out. This bill is targeted specifically at keeping manufacturing/fabs on American soil with an American company. Apple, NVidia and AMD are design houses and manufacture mostly with TSMC, a Taiwanese company. With PRC breathing down Taiwan's neck, there will be a major semiconductor supply chain disruption should PRC start any aggressions towards Taiwan. It's also a major national security issue if the US gov't and defense industry must rely on Asian manufacturers for their semi manufacturing.
And then there is the economic interests at hand. Intel is talking about up to a $100 Billion investment in Ohio. That's a hell of a lot of good paying tech jobs created, plus all the support and service industries & businesses that will flourish in that area creating even more jobs and tax income. Is AMD or NVidia doing any investments anywhere near that size in the US? No... And it is also a possibility that these CPU design only houses could become customers of Intel with the foundry services ramping up....
