- Both have 8 core Jaguar X86 CPU [lowpowered ahitecture aimed at ultrabook-grade laptops].
- PS4 has 8 gigs of GDDR5 ram, Xbox One has 8 gigs of DDR3 ram that is 3x slower than GDDR5. To offset that, XO GPU has 32megs of onboard cache that is 60% faster than DDR3.
- PS4 GPU is 50% more powerful at same clock speeds, and there is a very high chance that PS4 OS will require less processing power/ram to work.
All in all, XB has more complicated architecture, with slower hardware, and beefier OS. Sony clearly aimed to create GAME console, MS aimed to create cheaper ENTERTAINMENT box.
