About the DDR3 vs. GDDR5.
The GDDR5 used by Sony uses less power than the DDR3 used by MS... Sony choose a Green GDDR5 with the lowest clock possible... it uses less voltage and power than DDR3 at high clocks like the Xbone.
The APU is smaller so it is easy to cooler then the MS APU too... I guess the MS one uses more power too because it have to maintain the eSRAM part (40% of the chip) on too.
