    OK, I have a AMD Athlon XP 2000 chip, but the ACTUAL clock speed is ONLY 1.67 ghz instead of 2 ghz. (Now I understand the theory of how a 12 speed can overtake a regular bicycle when it changes gears even though the regular bike is faster) But here's my question.....I am kinda puzzled at these new processors that AMD has come out with! Take their "flagship" processor The AMD Barton 3200. The 3200 is REALLY misleading, because instead of even "comming close" in core memory like my xp 2000....the 3200's core memory is ONLY 2.2 ghz!! But you are talking about a processor that is SUPPOSED to be able to OUTPERFORM a Intel Pentium 4 3.2 ghz chip?? That seems like it is a stretch! THAT IS A 1 GIGAHERTZ LACK OF CORE MEMORY BETWEEN THE TWO! Now I know that in my athlon xp 2000, they can make it perform better than a regular Pentium 4 2 ghz chip by increasing the chips overall performance speed.....but to market a chip and say it will perform as good or better than a Intel 3.2 Ghz and you CALL your chip the 3200....BUT are only working with 2.2 ghz of stock speed!?? That seems to be an impossible task! I can see how a xp 2000 can keep up with a Intel 2 ghz because there is only a 300 mhz difference between the two chips, BUT HOW CAN YOU JUSTIFY CALLING A AMD 3200 CHIP THE SAME AS THE INTEL 3.2 ghz????? It just seems too far of a stretch if you ask me! By the way, I know you can also overclock your processor as mine would be easy to overclock to 2ghz....but I have never HEARD of anyone being able to overclock a chip 1ghz worth!! Which is what you would need to do to bring it up to speed with the 3.2 Intel. It just doesn't make sense to me!

    The 3200+ rating is a direct mathematical computation where they take computations per cycle multiplied by megahertz.

    So with your bike analogy, its like a bike with larger diameter tires don't need to spin as fast to go the same speed.

    ever heard of the 'megahertz myth'?

    megahertz isn't everything :devil win

    Guys that is all probably true, BUT YOU STILL HAVEN'T EXPLAINED ABOUT THE 1 GHZ CORE MEMORY DIFFERENCE! Until somebody can explain THAT one to me, I am going to have a hard time buying it!

    YES I have heard of that myth, BUT COME ON! A 1 ghz difference in core memory IS NOT A MYTH! It is a fact!

    It's a PR rating that AMD uses. Intel and AMD chips are designed very different and there is no point comparing them on a mhz for mhz basis. So AMD uses this PR rating to help people that are accustom to Intel's 'mhz is everything' approach. Otherwise people would look at AMD's 2.2 ghz 3200+ and then look at Intel's 3.2 ghz P4 and assume the AMD chip performs like a 2.2 P4 which would be a very false idea. So I don't really care how big the mhz gap is as long as the chip can perform. Granted the 3200+ can't quite catch up to the 3.2 P4, but it is close enough in my book.

    Megahertz and Gigahertz are IRRELEVANT measurements of a processor's capability.

    It would be like selling a car with an engine that can go 16,000 RPM. Well what the f*ck does 16,000 rpm mean? Two engines from different brands both with 16,000 RPM might be WAY different in total power depending on how they are designed.

    webe3, does a Celeron 2 Ghtz = P4 2 Ghtz???

    Let me clarify. The only time that Megahertz or Gigahertz IS Relevant is when you are comparing directly between the same processor line from the same brand, with the same core design, same transistor size, and same bus speed. Then it is SOMEWHAT relevant.

    From what I have read..... NO! I have heard that the celeron 2ghz is a value chip and aimed at lower end markets and does not have all the bells and whistles of a pentium 4 2 ghz. But I am no processor expert! To tell you the truth I have not compared the benchmarks of those two!

    Hmmmm.......so I guess you are saying that I am comparing "apples to oranges"????
