Thanks! There was a channel update video a little over a week ago, which offers a bit of an explanation.

If memory serve, the Pentium III, M and Core were all based on the P6 architecture, did they share the same front-end ? I remember mounting a pentium M on a Asus motherboard, it was a beast. ( I also had a Cyrix P166+ , celeron 300A and an Athlon Thunderbird, this bring back memories ) Really eager to see the difference between P6 and K7. Like Weird Al Yankovic said "It's All About the Pentiums" :D

Sort of. The Pentium II/III share the same front end, which was introduced in the Pentium Pro. Core went back to the P6 architecture and updated it. Core is similar to the P6, but not identical (the front end is wider on Core). I'm not as familiar with the Pentium M, but it looks like it was an iterative step between P6 and Core (based on the P6). The P6 vs K7 is probably the most interesting comparison, since they are so similar in some ways and so different in others. There isn't a lot of information available with P6 though, so it won't have as much detail as the K6 and K7. And I have to admit that Weird Al Yankovic's song was stuck in my head while working on these videos.
