Hey guys, sorry about the long response time. Seems this article’s been getting quite a few responses. I’ll do my best to respond to each one individually.

First things first: for everyone saying the article is incomplete, I’ll be posting a follow up to it some time in the near future (unfortunately, I’ve no direct control over when my articles go live).

Article warns that it is going to be technical, I get excited, and am now very disappointed at learning precisely, nothing.

I agree with Andrew. How about some product examples etc. This article seems to just get started then ends :-/

Cycles actually USED to be a pretty good way of determining the amount of work a processor could do many years ago when they were much the same.

CPU’s now do different amounts of work and different types of work per cycle.

This article is incomplete. It should just be starting where it ends. The simile is nice, but how about relating it back to how processors compare to one another. The whole “half the time, but same work” bit sounded like a comparison between a 64 and 32 bit processor. Also I can’t help but nitpick that 2 GHz is not the rate at which the computer completes a single cycle. It means 2e9 cycles are are completed per second.
