If that's true, then why haven't the prices for high-end chips changed over the
years? A better market strategy would involve keeping prices the same for
lower-clocked chips and introducing more expensive high-end chips. Every time
Intel releases a new high-end chip, the prices for their other chips drop.

Either AMD's marketting dept. is incompetant or they disagree with you. They
felt it would be better to delay Clawhammer until September rather than release
in January. The same thing happened with the K7, and it has happened with
various strains of the K7 too.

Maybe AMD does, but Intel doesn't. You aren't a major buyer. Dell and Gateway
are. The teeming masses buy prebuilt computers from major vendors, and most
major vendors don't even sell AMD. The ones who do usually sell AMD as the
"low-end economy PC" rather than being on-par in performance for less money.
Since most people believe in the idiom, "You get what you pay for," they'll buy
the 3.06 GHz Intel because it's more expensive.

If they were selling a 5 GHz today, they would probably be selling a 5 GHz in 2
years, and you wouldn't be enticed at all to buy more of the same stuff. The
average lifespan of an x86 core is something like 5 years. You will upgrade
twice during that time, but you probably wouldn't upgrade twice if they hadn't
produced anything better.

On a Caddy that may be true. When the same manufacturing process yields a 2.8
GHz Pentium 4 and a 3.06 GHz Pentium 4, they do better by appealing to supply &
demand and letting people buy the 2.8's at a hefty price and then rolling in the
3.06's. I know a fair number of people who upgrade every year which is the
difference between the 2.53 and the 3.06.

Not in the short-term, but in the long-term it does.

I haven't done any overclocking, but I do read reviews from time to time which
generally include all the overclocking info. It seems to me that slow ram, slow
chipsets, and locked multipliers are more the issue than what the chip is
capable of running at.

I've heard of many cases where someone takes a processor and clocks it well
beyond the fastest offering for both Intel and AMD. The case I gave above it
real -- someone I know overclocked a 1.6 GHz Pentium 4 to 2.66 GHz. Others have
clocked Pentium 4's to 4 GHz. When 2 GHz was the limit on the P4, some were
clocking it to 3 GHz.
