Check out this interview with the actual architect of Zen, Mike Clark. [VIDEO] Probably the most interesting nugget is that Zen2 was actually considered a tweak internally and not a full uarch revision, while Zen3 is actually the clean-sheet revision. But it's just a good summary of the general tone and tempo of CPU development I think.

Actually, Mike Clark is the 'father of Zen': [VIDEO] . When Jim came along, Zen design was mostly finished already. Another honorable mention would be Suzanne Plummer

Jim Keller is tied to basically every ground-breaking architecture of the last 30 years. Not that everything he's worked on has been a hit, but, if something ended up being a huge success there's a high probability Jim Keller has been skulking around somewhere. Conroe/Sandy Bridge are the only ones that come to mind that haven't been him. His greatest hits: DEC Alpha, AMD K7 (Thunderbird/Athlon), AMD K8 (Athlon 64), Apple A5, AMD Zen... probably others I'm forgetting. Like god damn can someone else in the industry have some ideas of their own please, lol /s And again not that other people aren't involved either, in particular Mike Clark was really the guy who executed Zen development, but Keller was there at least as an advisor for a lot of the early development. He's one of Zen's uncles, Clark is the father. [VIDEO] I think it also says a lot that he completely fucking bailed from Intel after only being there a couple months... I think he saw they just weren't ready/willing to execute well and his time would be wasted there. He's the wandering silicon samurai who drops some golden nuggets of advice and wanders off into the sunset, not a babysitter while you purge middle-managers playing office politics.
