Intel isn't giving AMD time to breathe
Intel can carry on at this pace indefinitely. While AMD is *close* to unveiling Barcelona at a slower-than-expected clock-speed, Intel is ramping up 45nm production.
Don't forget that Intel is preparing for a new mobile chipset, has gobs of cash, and fabrication/distribution isn't an issue.
Meanwhile, AMD is floundering in debt, falling behind it's own schedule, and falling even further behind Intel.
As a geek, I enjoy the competition and do not have a favorite (I type this on a machine with an AMD CPU). As an investor, Intel is clearly in the lead and the difference is only increasing.
I picked up some INTC months ago and have not regretted it.
