Core i9-12900KS World Record: How I Hit 7.8 GHz on 8 Cores

In essence you get a CPU that is 4 (!) architectures newer.

Here are the architectures of Intel (according to Wikipedia):

1. i686 (Pentium Pro, Pentium II, Pentium III)

2. Core (Core 2)

3. Nehalem (Core i7-920, Core i5-750)

4. Sandy Bridge (Core i 2000 series)

5. Haswell (Core i 4000 series)

6. Skylake (Core i 6000 series)

7. canceled due to low yield

8. Sunny Cove (Ice Lake mobile 10xx and desktop 11xxx)

9. Willow Cove (Tiger Lake mobile 11xx)

10. Golden Cove (12xxx and 12xx)

Did you purposefully leave out Broadwell, or was it a mistake? (If it wasn’t a mistake, I’d be interested to hear you expand on why, I know it was a bit of a weird release.)

I think broadwell was a process shift, not a microarchitecture shift.

They also left out the whole Netburst (and it's decedents) arch too.

Netburst is not based on P6 (i686). Core is a development stemming directly from Enhanced Pentium M which stems from Pentium III. All others build on this. Broadwell is Haswell on a new node (14nm instead of 22nm).

I think Intel would rather we all forget about netburst.
