Negative.  HW RAID cards may have specialized hardware for doing XOR
calculations.  However, no raid card currently on the market has a 3.2GHz
xeon at it's core.  Most are ARM (up to 750MHz?) or i960 (up to 66MHz) based.
The system CPU can certainly out perform the tiny processors on the raid
card.  Of course, if it's doing raid calculations, it's not do general
computational work which is one reason to use hw raids.
