This CPU should be called Pentium 4 Xeon, but Intel opted for the name “Xeon”. As we mentioned before, Xeon is a Pentium 4 version targeted to servers and workstations. So it is a 7th generation Intel CPU. The models from Xeon series we’ve seen so far used Intel’s 6th generation architecture, the same used by Pentium Pro.

The difference between Xeon and Xeon MP is that the first only allows symmetric multiprocessing up to two CPUs, while the second allows symmetric multiprocessing with four or more CPUs. Actually when it was first released Xeon processor was called “Xeon DP” (meaning “Dual Processing”).

Xeon processors have 8 KB L1 data cache (16 KB on models that have the 64-bit EM64T technology) and a 150 KB L1 trace execution cache. L2 memory cache can be of 512 KB, 1 MB or 2 MB and some models have a L3 memory cache of 1 MB, 2 MB, 4 MB or 8 MB.

In the table below we listed all Xeon models released to date.
