According to http://users.erols.com/chare/elec.htm, P3 OLGA (aka secc2 aka slot 1) 500 MHz consumes 28 W whereas P3 FCPGA (aka socket 370) 500MHz consumes 13.2 W. I am not an expert in CPUs, so I might be wrong. On the other hand, I have a 2GHz athlon box and it takes 150W from mains and I have P3 667MHz Socket 370 and it takes just 30W (I measured this using clamp amp meter). 5 times difference !!!
