With Intel's recent purchase of TSMC excess capacity almost equaling AMD's total TSMC allocation I would say that AMD's enjoyable process node advantage has come to an end. Intel's purchase of that capacity also means that AMD (which is fabless) will now have to go to other fabs (Samsung) to produce additional chips. While not impossible this will be a pain for AMD. Someone in here will correct me if I am wrong, but I don't think GlobalFoundries even has a production node pushing under 12-14nm so they would be out of the question. With TSMC producing 7nm Intel is just a matter of time before moving there with their fabs. They have usually enjoyed a full node ahead advantage though and Intel would need to skip 7nm and go straight to 5nm in order to get back into their historic position (Before it starts I know that Intel doesn't measure the same and Intel 10nm is on par with others 7nm). I don't see this happening with their fabrication node delays. AMD and Intel are going to go head to head based off of their design teams, not process advantage. My guess is that we are in for a worsening supply shortage of high end processors built on the latest process nodes with everyone pulling from two global fabs instead of three and no one willing to increase capacity due to Intel's position. I think these supply shortages are what is going to slow AMD's market share growth.
