i have an amd athlon xp 3000+ processor

when i execute the dxdiag command, it says it is running at ~2.2GHz

is it suposed to say this? i thought that having an amd 3000 would be the same as having a 3 ghz pentium... correct me if i'm wrong please

It performs the same as a 3 ghz but in reality its just a 2.2ghz. Don't know the whole technological info on how it does perform the same but someone should know. They name it a 3000+ because if the general public saw a 3.0 Ghz and a 2.2ghz for the same price they would definitely go for the 3.0 ghz without even knowing that they perform the same.

thanks man, i fell all warm inside :) you just made my day, i actually thought i was being ripped off or something
 
The reason it performs the same as a P3.0ghz is because the AMD's handle 2 clocks per thread or something and the pentium's only handle one. Its quite complicated but im sure someone will describe it better than me. So now you know if you see someone running an AMD at 3000mhz thats like the equivalent of someone running a p4 at about 4200mhz
 
Basically, Athlon processors run much more efficient than Intel ones. So while Pentium chips run faster, you could think of them taking smaller steps in a race, so to speak.
 
Intels perform one task per cycle, or one calculation per mhz, while amd does two.
 
the AMD ranking hierarchy is based around competition with Inte'ls cpus. Think of your XP3000+ being able to process about as much as a 3.0ghz P4, even though it runs slower.
 
This is too much I know but oh well.

GHz/MHz is just freqency. How often it performs in second.
OPC is Operations Per Clock Cycle. One of those MHz.
IPC is Instructions Per Cycle. The full clock cycle or 1 second.

------------MHZxOPC=IPC
Pentium 4: 3200x6=19200
Athlon XP: 2200x9=19800
Athlon 64: 2200x12=26400

Hyperthreading adds to the Pentium4's IPC when applicable.
Other issues such as depth of pipeline, shorter is better (listed short to long:AthlonXP,Athlon64,Pentium4), memory latency and bandwidth come into play.
Also how their Cache systems function plays a part.
Athlon, none of the data in the L1 or L2 cache is the same.
Pentium4, it saves a copy of the L1 in the L2 cache. Not sure if it's the same with L3, I doubt it.
 
So my athlon is 2400x12? which is whatever?
