Question Intel had a 7 GHz CPU years ago

213 mm2 die size, 150 Watts, 50 pipeline stages all for one core at >7 GHz.

I'm getting a strong feeling of lust for this CPU. 150W ain't that much. Imagine what this CPU could have been if it had been developed further, with modern branch predictors and huge caches.

At this point I think I'd rather bang my head against the wall than discuss this anymore. You know what they say when you think you are right even everyone else tells you that you're wrong. You're wrong.

It's not about right or wrong. P4 was a baby killed too soon. It could've grown and become a beautiful swan.

You are only thinking of the P4 design being static and not evolving. That's not how CPUs evolve. They get better with each iterative design.

I believe Intel may never revisit P4 because they like to think they are too wise (explains their current predicament). I think a better outcome would be selling the design to china and let them iterate on it. I would certainly buy it if I were a billionaire.
