I?ve noticed a lot P4 based motherboards featuring four phase power designs for the CPU, while not many/any for the Athlon. The power consumption between the P4 and the Athlon always seemed pretty comparable. Is there any reason why there are more P4 based systems with 4 phase power then the Athlon? Are P4 motherboards built to higher standards or is it not as big of a necessity for Athlons?
