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.

On the graphics aspect it’s another time obvious that Microsoft and Sony are searching at a similar store because the Xbox One’s SoC integrates an AMD GCN primarily based GPU. Here’s wherever things begin to induce somewhat polemical. Sony opted for an eighteen cipher Unit GCN configuration, totaling 1152 shader processors/cores/ALUs. Microsoft went for a way smaller configuration: 768 (12 CUs).
