HELP! Trying to understand the logic behind CPU core speeds and whole CPU speed.

    Hello All!

    I seemed to understand how Intel and AMD marked the speed of their
    processors until recently...
    OK, I got the marking of AMD's x000+ range. Their actual speed was
    lower in GHz but the output was that of a like for like in GHz terms.
    With the introduction of Dual Core architecture AMD was still marking
    their processors as xxxx+ (I have a dual core 4400+ AMD 64) then
    suddenly all those PLUS things have gone and we are back to pure GHz
    terms. But now my question is this:

    Does a Dual Core processor marked at 2.4GHz mean 2 x 2.4GHz OR 2 x

    Thanks for help.

    It means total speed, and fairly useless unless you have software to take
    advantage of the dual processor.
    Not much does at the moment so you are better sticking to a normal
    processor. It is faster!

    It is for a server, so it would take advandage of separate cores.
    Thanks for your reply.

    It is not just a matter of processor speed.
    The Core architecture introduces a number of technologies that make the core
    duo processors faster than those based on the older netburst architecture.
    Even the slowest core processors perform on par with the fastest of the
    netburst type in most situations.
    To oversimplify the situation let's just say that core features a shorter
    and wider pipeline, resulting in more things being done per clock cycle.
    Also a lot of effort has been put into ensuring that the pipeline remains
    For a thorough explanation of the differences please visit.

    Thank you for the reply and an interesting artice, however it applies
    to Intel cores and not to AMD cores.
