BleepingComputer.com: AMD CPU

hi,

why are AMD CPUs shown as 4200+ instead of the normal GHz?

And also on Intel CPUs it shows the FSB on the cpu but on AMD cpus it doesnt show the FSB, why is this?

I can answer the first part of that at least.

When Intel released the P4 it was discovered that MHz no longer was indicative of performance. P4 CPUs had higher clocks, but clock for clock performed worse than PIII and then current AMD offerings. The marketing guys at AMD, in order to "educate" the buying public, came up with "Performance Ratings". The idea was a 3200+ rated AMD was comparable to a P4 3.2 Ghz piece etc. Now with the myriad of architectures out there, the numbers are just a number and can only be used to rate a CPU within it's own family.

I knew what AMD's "theory" in naming their CPU's was but I have always felt it is simply misleading & a blatent attempt to make thier product sound better then it is.
When AMD started that I wonder how many people were disappointed to find out their spiffy new "3200+" CPU was actualy 2.2GHz.

Calling a 2.2GHz CPU "3200+" didn't make it "as fast" as a Intel 3.2GHz in the real world.

That is one of the reasons I don't like AMD .

If you go here,

& compare the Athlon XP 3200+ to a Pentium 4 3.2GHz you will see the difference.
I am comparing the Athlon XP 3200+ to the P4 to keep it real.
The Athon XP is the CPU that AMD originally released & claimed was rated "3200+" because it is "equal to a P4 3.2"
the later Athlon 64 3200+ was STILL a tad slower.

Chart ratings,
Athlon XP 3200+ = 446
[Athlon 64 3200+ =486]

Pantium 4 3.2GHz = 510

Keep in mind "almost as fast" doesn't count .
AMD rated thier CPU's as the equivalent of the Intel's

That 64 points difference in the rating may not look like much but in the real world it's noticable .

BTW, To find the Athlon XP 3200+ simply go to the bottom of the chart.

AMD doesn't have a true FSB. Intel does.
