Subject: the AYHJA t-bird is not an MP core

Author: K. Burcham

my 1400 t-bird reads this on the core:

         A1400AMS3C
         AYHJA  0125UPNW
         Y6492230454
            1999 AMD

my AYHJA has a longer horizontal dimension.

 you will notice in the pictures that the t-bird, including the
     AYHJA core, has a longer horizontal dimension.  the mp core
        has a longer vertical dimension.  pictures can be found at
          anandtech, below.   i know it is not clear, but i magnified
            the t-bird and it is an AYHJA core.

here you can see the revisions that were added to the AYHJA CORE.

here you can see the revisions that were added to the mp core.

revisions are not the same.


here is another good example:

    i also have a 1 gig axia. this core is longer horizontally, and looks the
        same as my AYHJA when i hold them beside each other.  here is a good
          picture of a t-bird axia beside an mp.

also  the current draw could be monitored while the percent of cpu usage was
         at say 95%.  in this test, the palomino at 95% cpu usage, the current
             should be considerably less  (about 15%), when compared to the
               standard t-bird AYHJA   core, with the same 95% cpu usage.
