Xbox One versus Sony PlayStation 4

The move off from PowerPC to 64-bit x86 cores means that the One breaks backwards compatibility with all Xbox 360 titles. Microsoft won’t be following any variety of a backwards compatibility strategy, though if a game developer wished thereto may port anolder title to the new console. Oddly enough, the primary Xbox was additionally x86 style from a hardware/ISA viewpoint the new Xbox One is backwards compatible with its grandfat, though Microsoft would ought to modify that as a feature in software package, one thing that’s quite unlikely.
