People say that you only experience more speed if the software is written
for Dual Core technology. However, I bought a Dual Core processsor machine,
and it is much much much faster with the dual core. Is everyone wrong?

bet the cpu is faster than your old one

No, they are correct. The processor is faster than your old one, as is the
RAM. That would account for the speed difference.

?. I have not seen anyone claim that that their software was especially
written for dual core machines (and have never seen anyone state that such
is really a requirement.

Don't forget the increased L2 cache size.

Nero 7, Photoshop, and others can run faster on a dual processor machine.
The number of titles will grow once Vista hits the street and a 64 bit
multithread OS is "normal".

Good article, Robert. A lot of folks have difficulties understanding
these basic concepts, you have well explained it in easy to understand
language.

Most of those people have never worked with a Dual CPU or Hyper-Threaded
or Dual Core system.

In my experience, the following is true:

Windows XP (generic user)
P4/3.2Ghz non-HT and not-DC Rating 1.0
P4/3.2Ghz + HT (not DC) Rating 1.2 max, sometimes .95
Dual Core (2.6Ghz) Rating 1.6 or more (can be 2+)

Windows 2003 Server - about the same

It really depends on your system, as XP does support Dual CPU's and Dual
Core looks like Dual CPU's to XP, but it's about the apps, and good apps
can handle many threads/paths and benefit from the Dual capability.
Other apps have little real innovation and no ability to use multiple
threads, these won't perform much better.

You should always see some benefit, as OS related tasks can be spread
over both cores/CPU's, so not everything is stuck waiting.

I bought a Dual Core 2.6Ghz machine and put it next to a 3Ghz Xeon and
the 2.6 with a cheap $59 video card ran circles around the Xeon playing
Guild Wars :)

They've read a 'theoretical' note about how a program needs to be written to
directly benefit the most from SMP and extended that to the whole system
envionment.+

Not really. It replaced an Intel HT 3.0ghz

What isn't true is that the software must be written to take advantage of
the duals. It used to be true, but nowadays there are two modes; one for
the special software and one for the CPUs to share work, but it may or may
not be obvious.
Only two physical cpu's can actuall speed anything up. Otherwise it's a
data manipulation setup. One cpu can do only one max set of instructions;
and that's all.
