Outside of what has already been said (they will lose the x86 license supposedly, though I'm not sure that would actually happen), such a deal would never go through. Many of these larger companies are under threat of getting broken up. While Microsoft is certainly toward the bottom of the list, they are, in fact, on the list.
So, I take it you think unicorns are real as well?
I disagree with ANY assessment that claims Intel beats AMD in perf/watt. If that were the case, the 12700k would beat the 5900x @ 105W, and the 12900k would beat the 5950x @ 105w. Not only that, but AMD's current architecture is a year old. Yet their server SKUs are WAY ahead, desktop SKUs are mostly ahead, and laptop? that market right now has AMD ahead, with Alder Lake MAYBE catching up or possibly beating Cezanne. Rembrandt and ADL should go head-to-head soon, and we'll find out...
Some of you guys (not Mark, I actually agree with most of his viewpoints, but rather, you Intel folks) that are trolling these threads need to take a chill pill. Intel IS trying to execute better, but they haven't yet reached the point where they can declare the win over AMD. If you think otherwise, I'd like for you to find me an Intel CPU that beats my 5950x in the majority of benchmarks at 105W + another 37W or so for the complete SoC. I'm not making excuses for either vendor (lol, I own stocks in both along with TSMC, etc. those stocks just all go up don't they?

) but currently the winds continue to blow in AMD's direction, hence why they don't care about the gimped rooster crowing over at Intel.
