I don't see any complaints of that nature in the article. He points out that is has a lower clock rate due to the shorter pipeline. Which is objectively true. And then later he demonstrates that xbox cpu is faster and suggests that the lower clock rate of the gecko is a major contributing factor as to why, which again is objectively true.
MaJoR Wrote:The prevailing thought at the time, from everything I've seen, was that IPC was irrelevant when you could just go to higher and higher clocks.
I would have to disagree. Any engineer worth his salt knows that both IPC and clock rate are equally important to performance. This is very well reflected in literature from that time including the article you linked.

Surprisingly....no. Been searching google for 15 minutes now and I haven't found jack squat. But I know it's out there because I've read it before from multiple sources that worked at Intel. I will keep digging when I have time.
