Surprisingly, power consumption levels on the Athlon II X4 620 were only slightly higher than those of the Phenom II X2 550, despite featuring two extra cores. AMD's latest chip also used considerably less power than the Core 2 processors under full load.
In fact if it were not for the Core i5 750, consumption levels on the Athlon II X4 620 would be very impressive, but Intel's latest platform is the clear winner here.
