thanks! FYI!
The Xeon is Intel's name for its server-class PC microprocessors intended for multiple-processor machines. The name has been kept over several generations of processors. Older models added the name Xeon to the end of the name of the corresponding standard range but the more recent models have just used the name Xeon on its own. Xeon chips generally have more cache and support larger multiprocessor configurations than their desktop counterparts.
