    Xeon vs. Pentium IV


    Hey there,

    I'm not sure how involved this question is, but what is the difference between a Pentium Xeon processor and a Pentium IV processor? Is one particularly better than the other? Also could someone maybe point me in the right direction on where I can learn more about there differences. Thanks!

    Been a while since I spec'ed out any of the new Xeons and compared them to the P4's.

    The biggest difference? The Xeon chip can be used in a multi-processor system. The Pentium 4 chips can only be used in single processor systems. It used to be that the Xeon's came with more on-die cache than their P4 counterparts, although I don't think this is neccesarily true anymore.

    Xeon's are meant for server environments or applications that would benefit from multiple-threads spread over multiple CPU's, such as video/graphics rendering and database apps.

    I'd check out www.intel.com and look at their spec finder tool. Compare the specs and see if there is any difference on a chip-to-chip basis.
