Yeah, I didn't mention Intel, I know they have fabs domestically but they're also moving to TSMC after 10nm [1] so I figured they were getting out of the game.
That's a bullshit rumor from a bullshit site that you're misinterpreting anyways. Intel might plausibly use outside fabs for their new discrete GPU product line, but they are absolutely not getting out of the fab game in any meaningful way. They are capacity-constrained at the moment and don't really have room to make big GPUs in-house without subtracting from their manufacturing capacity for their well-established CPU product line.
Good call-out re: GF.
