Like at this point it should be clear to all of us that fabs are only one part of the entire equation. The progression from pentium to core, or bulldozer to zen, both exemplify how its design that really drives the overall performance. Design does have to consider the nodes available yes, but ultimately from a physics standpoint, there's only so many ways to get work done and speed is something you measure. You don't assume the top value of a gauge is the actual performance for most things in life.
Intel has had a massive middle management problem for a while now, and it continues to show. The fact that 13/14th gen chips had degradation issues, and the delay in getting angstrom chips out just goes to show that PG didn't fix the core problems. I truly believe intel has good engineers, good fabs, good designers, but something else is preventing everything from mixing coherently.
I really hope the company gets it together because a world where intel chips are way slower and hotter than the competition is very sad to me. If anything we're quickly approaching an age where intel GPUs are the real gangbuster and most people will be paring them with AMD CPUs, a complete population inversion of just 15 years go. And yet another symptom of total mismanagement.
