But that's exactly my point -- nobody waits. Intel wins by staggering release
because you upgrade through multiple releases of their CPUs. If they released
everything up-front, we would all buy the high-end chips instead of buying
high-end now, high-end in a couple years, more high-end a few years after that,

If you buy a slower processor, criteria (a) is met more often, and it doesn't
cost Intel anything extra in the desktop market. Perhaps you might not buy that
frequently, but some people do. I know a fair number of people who will squander
money on the fastest thing Intel has to offer, and they do it every 6 months. If
Intel can sell them the same chip on the same process twice (i.e. 2.53 and 3.06
GHz), Intel makes out like a bandit. A Pentium 4 costs nowhere near $600 to

I wasn't talking so much about requirements. I was thinking more that few people
will upgrade from a 2.8 GHz Xeon to a 3.06 GHz Xeon because it is
cost-prohibitive and returns very little additional speed. The point is that
people will buy the 3.6 if available, otherwise they buy the 2.8 (or whatever
-is- available). If they buy the 2.8, they're more likely to upgrade when the
4.0 is released. If they get the 3.6, there's no chance.

Yes, but that isn't exactly desktop world, is it?

And if Intel staggers a CPU core to last 6 years, they've protected their

Ironic that my example a couple paragraphs above is so similar. Intel isn't
expecting that you will buy the 2.8, 3.06, 3.2, 3.5, etc. Intel is expecting
that you will buy the 2.8 and then upgrade to a 4.0. If they released a 4.0, a
3.6, a 3.2, and a 2.8, they wouldn't get your money for the 2.8's. If they
release incrementally, there is a chance they will get your money for the 2.8's
and the 4.0's. As you said, many new systems are being sold, but Intel isn't
losing their business. Intel has nothing to lose and everything to gain.
