It isn't all about MHz, if it was everyone would have a P4. The Athlon 64s are
faster than your Tbird MHz for MHz.. plus the added cache, much, MUCH faster
ram, lower memory latencies, higher bus speeds, etc. It doesn't have to run
2.8GHz to be twice as fast. In most applications/games 2.2GHz/1mb L2/dual
channel DDR Athlon 64 will run over twice as fast as a PC133 SDRAM based
Thunderbird 1.4GHz.

As far as chess goes.. where cache, memory speed, etc make little difference..
you'll still see a large increase. If you figure about a 20% +/- 5% increase MHz
for MHz over a Tbird then an Athlon XP 3400+ (2.4GHz/512k l2) will run about
like a tbird 2.4*1.20 = 2.88GHz.

Also, you have to figure in marketing. Intels 90nm Prescott isn't able to hit
4GHz (it was recently cancelled). AMD is just getting started. They can released
2.8s, but, why do they need to? They already released the 4000+ and FX-55.. both
of which in the consumers eyes beat the P4-3.6GHz and soon 3.8GHz. So releasing
an even higher part (4200+, 4400+) will cut into the sales of the lower end
chips and drive the prices down quite a bit.

Another thing is it is nice for them to be able to just add on more cache, run
dual channel, increase the bus, etc and be able to increase the PR without
increasing clock speed. This is what people look at (the PR). Intel can take a
P4-3.2 for example and throw L2 cache on there, increase the bus and people will
still see it as a P4 "3.2GHz". I'm talking about average consumers (which make
up nearly all of the market), rather than the more knowledgable people.

Even my Athlon XP 1.83GHz (2500+/166fsb) @ 2.6GHz (4200+?/218fsb) w/ the Nforce2
chipset is faster than the Tbird 1.0 @ 1.4GHz that I have here. It is an iWill
KK266 (also use the Abit KT7a, as well as an Abit KT7a-raid) with 512mb PC133.
The Athlon XP at "only" 2.6GHz is over twice as fast in just about everything.
Excluding stuff that is strictly cpu bound, then it is a linear increase up from
1.4.

With a nice Athlon 64 system running on a 74gb 10k rpm SATA Raptor drive.. I
don't see how you could get disappointed in any way. ;)
