Well, I wrote a small article on my website a while back for this very occasion (
www.casualconsulting.com). Don't try to access the website, it will be down for about a month until I get back from vacation in Florida next month.

So your friends are telling you that Pentium 4's are the "rave", your local sellsman is trying to sell you a Pentium 4 PC, and you have ALWAYS heard how great Pentium 4's are. Well, I'm here to give you the facts so that you are not mislead.
The largest misconception among PC buyers is that Pentium 4 is leading the market. We are in a new melinnium, and Intel no longer is THE king baby. For years now AMD has been the forefront of technology, closely being chased by Intel. To your delight you will be glad to know that you can buy a AMD processor which performs just as great as the equivelant Intel for a much lower price.
A basic easy way to explain AMD vs. Pentium is this; AMD processors are a "higher end" processor which run at a lower MHz than the equivelant Intel processors, but actually perform about the same. If you were to compare some of the most popular processors as far as quality and speed they would be listed something like this:
#1 AMD Athlon
#2 AMD Duron
#3 Intel Pentium 4
#4 Intel Celeron
Another thing you may find interesting is this; AMD and Pentium both have their version of their fastest processor. AMD's fastest processor is the AMD Athlon, and Intel's fastest processor is the Pentium. They also have their own versions of lower priced, slower processors. AMD's version is the Duron, and Intel's version is the Celeron.
If you look at a AMD processor you will notice that they have ratings specified by numbers such as "2100+". This number means that the processor runs at the speed of a 2.1GHz Pentium 4 processor. Although a 2100+ AMD processor's speed is 1.73GHz, since AMD's are a much higher quality and faster processor they run at the speed of a 2.1GHz Pentium 4.
You may find it very pleasing to know that AMD's processors are not only much faster and of much higher quality, but they also are much cheaper! Want to compare prices? Lets!
AMD Athlon XP 2.16GHz 3000+ $270.00
Intel Pentium 4 3GHz $423.00
That is a $153.00 difference!

These two processors run at the SAME speed, but do you see the price difference? Before you take me too literally, remember this; speed is actually not everything. Two processors running at 3GHz does not necesarilly mean they both actually perform at the same speed. Although they both technically run at the same speed, the fact is, you must factor in the quality of the processor. A higher quality processor equals a faster processor. AMD is a "higher end" processor, Intel is a "lower end" processor (compared to AMD). Though you must realize is your processor does not solely determine the speed of your system, but also so does the speed of your RAM (but we won't get into that in this article).
One detail you have to take into consideration when buying a pre-built PC from a company such as Dell or a stand alone processor (if your building your own system) is that processors do not only have one detail you must worry about as far speed. Each processor has its own "Front Side Bus" (FSB). This front side bus connects the CPU with the main memory and is used to connect to other components within the computer. The faster your FSB, the faster your computer, because with a faster FSB your processor can "communicate" with the rest of the hardware in your system at a higher speed. Before I go any further let me point out something to you. Since were comparing AMD vs. Intel, lets use another example.
The specs below do not necesarilly mean that ALL of these processors run at these FSB speeds. Different model's of these processors may run at different FSB speeds.
Intel Pentium 4 3GHz @ 800MHz FSB
AMD Athlon XP 2.16GHz 3000+ @ 333MHz FSB
I know right now you may be thinking "wow! the Intel's FSB is 800MHz. That is MUCH higher than the AMD's front side bus! It must be much faster!". Technically, yes. Though the 800MHz FSB would be considered a lot faster, it isn't. Why you ask? I'll tell you exactly why. For the 800MHz bus to be utilized fully, then other hardware in your PC must also run with a 800MHz FSB. Since, most hardware today, even in hard core gamer's PC's only run at about a max of 400MHz then in that case only HALF of the 800MHz front side bus's power would be used. So you must ask yourself why spend much more money on a processor just because it has a 800MHz front side bus when it wont even be used? I wouldn't advise wasting your money.
