That's one reason but the other is the use of older semiconductor fabrication technologies ...

The PS3 Fat uses older semiconductor fabrication techology than the PS3 slim  is the PS3 fat underpowered? :)

No because when transitioning to newer semiconductor fabrication technologies we can reduce chip size and in turn with the chip area scaling improvements we can also see benefits such as reduced power consumption or increased power.
