Question Frequency - How much is process and how much is architecture?

Build a PIII 1000 on Intel 7. How fast does it run?

Build a 14900K on the PIII 1000 node. How fast does it run? Yeah, I know it'll be huge!

It's architecture + process + circuit design.

On the same 0.13u process Pentium M reached 1.7GHz, while Pentium III tapped out at 1.4GHz.

Original Itanium was 800MHz with a 10 stage pipeline. Itanium 2 cut it down to 8 stages and clocked 25% higher at 1GHz, all on the same 0.18u process, while the whole die wasn't that much bigger plus integrating an entire 3MB L3 cache which was the first processor to do so.

I bet that Pentium III made on Intel 7 would have a lower frequency than Golden Cove. Coves has more frequency-focused pipeline.

But I wonder how small an old x86 core like that could be if designed for minimal area.

So PIII 1000 on Intel 7? What do you think? Perhaps 2GHz?

How about Prescott on Intel 7? To the moon!

I think Tulatian on Intel 7 could hit 2GHz. Coppermine seemed to be at its limit but that seemed to be process related. It's a good question.

Prescott would be awesome but it will need to be modified to take advantage of modern area efficiency by giving it a huge cache. Then it's gonna fly to the moon! I'm betting that with 4 MB L2 and 30 MB L3 and frequency @ 7 GHz minimum, it may beat Core 1st gen.
