ECU

ECU Equivalent
1.2 Ghz Xeon processor released in 2007 actually has just as much processing power as a 1.7 Ghz Xeon processor released in early 2006. Furthermore a 2.0 GHz Pentium 4 performs just as much as a 1.7 GHz 2006 Xeon processor. The passmark of Pentium 4 2.0GHz is 247. We will assume every ECU is equivalent to passmark of 400.
