Intel has been stuck on the same process since at least 2018, and continually delayed their next node process.
Right now current estimates put Intel's 7nm node at least 2-3 years away... and that's after all the delays that they have already experienced. It's so bad, Intel is seriously considering outsourcing chip production for not just GPU's, but CPU's as well - that means Intel believes it's in a really bad position.
By the time Intel finally gets their 7nm process working at acceptable yields... 7nm will be old news. TSMC is working on 5 and 4nm processes right now, and of course AMD will be using them to their advantage at the earliest date possible.
Meanwhile, Samsung shipped AMD chips for Ryzen 1 (and 2?), and is producing GPU chips for AMD to this day. TSMC is producing Ryzen 3 (and possibly other things for AMD). Both companies will be producing something for Intel soon, it seems.
Like it or not, Samsung is obviously producing things Intel cannot.
Clearly, allowing Intel to use current state-of-the-art fab processes from whichever company at the time happens to be the best is a sure winner for Intel.
