    Processors are identified by markings known as Ordering Part Number (OPN).
    The OPN identifies the processor and its specifications.

    Is the OPN code on the retail box or the core?¿?

    It's on the CPU, might be on the box too.

    I don't think I've seen any codes on the box. They don't even tell you if it's a 0.18 or 0.13 CPU. You just need to flip the box over to see the core ( or the label next to the core for TBreds ).

    Just ordered a AXDA2100DUT3C (thats a 2100+ Tbred A or B at 1.6v and max temp of 90C and 266 fsb). So it could be an A or B. I'm hoping its a B... and I'm hoping that I don't have to use the wire mod to allow my motherboard to adjust its multipliers. Anyway thanks to all those who posted information on identifying the different XPs. Made me spend some money :(

    Edit: 2100+ AXDA2100DUT3C just arrived...
    AIUHB ;) High end Tbred B... :D

    Edit 2: 13x166 = 2153Mhz, 58C idle (too hot with silent Coolermaster HHC-L061 Heatpipe silent) and my board doesn't unlock multipliers :(

    I updated the table, however the document is from 24th March 2003, so it doesn't have all the latest CPUs.

    Recap on AthlonXP speeds ( Palomino, Tbred, Barton )

    It's not always easy to know at which speed your CPU is running when you only have the PRating, especially with the different FSB & L2 Cache combinations of CPUs out there.

    Here's a little resume that I hope will help some people.:)

    Palomino Core :

    256kb of L2 Cache & 133 (266) FSB

    1500+ -> 1333 mhz
    1600+ -> 1400 mhz
    1700+ -> 1466 mhz
    1800+ -> 1533 mhz
    1900+ -> 1600 mhz
    2000+ -> 1667 mhz
    2100+ -> 1733 mhz

    TBred Core :

    256kb of L2 Cache & 133 (266) FSB

    1700+ -> 1466 mhz
    1800+ -> 1533 mhz
    1900+ -> 1600 mhz
    2000+ -> 1667 mhz
    2100+ -> 1733 mhz
    2200+ -> 1800 mhz
    2400+ -> 2000 mhz
    2600+ -> 2133 mhz

    TBred Core :

    256kb of L2 Cache & 166 (333) FSB

    2600+ -> 2083 mhz
    2700+ -> 2167 mhz

    Barton Core :

    512kb of L2 Cache & 166 (333) FSB

    2500+ -> 1833 mhz
    2600+ -> 1917 mhz
    2800+ -> 2083 mhz
    3000+ -> 2167 mhz

    Barton Core :

    512kb of L2 Cache & 200 (400) FSB

    3000+ -> 2100 mhz
    3200+ -> 2200 mhz


    I'll post pics of the different cores as soon as I get all the pictures.

    How do I tell the difference between the Thoroughbred and the Baron Core? Bothe CPUs look Idential to me, is there something in particular that sets the CPU apart, that can be easily reconized from just looking at them?

    just know your processors

    only the 2600+ shares both(266/333) bus speeds from there on up it's a barton w/exception of the 2700+tbred...........and the 2500+barton....simple, isn't it :confused:

    The Barton core is "longer" then the TBred.

    Here's a picture of both right next to the other.

    If you can guess which is the Barton, you get an Ice Cream ( with the heat we're having these days, this contest should be a winner :D ).

    The right one is the Barton... obviously...

    I heard there was another version of the 2500 with a 266 fsb...

    Can you find anything about that, and how to avoid getting it?

    And, what the heck is this 'AQXEA' code all about?

    Nice thread. I better go double check my supposed XP2500, but I don't want to take off my damn heatsink. Isn't there a program where you could check the cpuid?

    Shame the links dont work realblackstuff, would be interested.
    it's easy to tell a Barton from a tbread, it's the last 4 characters of the code. i think DKV4D is a barton. if not, CPUID will tell you your L2 cache size, 512 for a barton, as you know.
    the easiest way to save all this brain-ache is to buy an Athlon64, like me :). (though, now ive got it, i think it's crap).

    Hey guys,
    I have a comp, that is well out of date, I am a gamer and the games I have now bog my system too much, and plus I just bought a new FX5700 Geforce 256MB card, and I have been told that its a power sucker. So anyways I want to upgrade from my Intel 1.8 processor and motherboard to a AMD CPU/Mother. I have 512MB memory and 107Gig Hard drive. that is only used up 20%. so im ok there i think.
    A friend told me that my processor was a crapi one and really ran at a1.6 or .7 and he said my mother board has a 400FSB but was really lower because my motherboard is pretty out of date and it wasnt a true 400FSB.
    so thats why i want to upgrade. to a AMD CPUand new mother.
    I really dont have a need for a onboard graphics chip with my motherboard that i buy, so that might take off of the price alittle.

    Anyways please help me find a good but cheap setup. I want atleast a 2.2G processor and a decent AMD compatible motherboard. any suggestions?

    thanks,:p
