IAmA CPU Architect and Designer at Intel, AMA.
Proof: Intel Blue Badge
I've been involved in many of Intel's flagship processors from the past few years and working on the next generation. More specifically, Nehalem (45nm), Westmere (32nm), Haswell (22nm), and Broadwell (14nm).
In technical aspects, I've been involved in planning, architecture, logic design, circuit design, layout, pre- and post-silicon validation. I've also been involved in hiring and liaising with university research groups.
I'll try to answer in appropriate, non-Confidential detail any question. Any question is fair.
And please note that any opinions are mine and mine alone.
Update 0: I haven't stopped responding to your questions since I started. Very illuminating! I'm trying to get to each and every one of you as your interest is very much appreciated. I'm taking a small break and will resume at 6PM PST.
Update 1: Taking another break. Will continue later.
Update 2: Still going at it.
