Microsoft could make the Xbox One "slimmer" and more energy-efficient by leveraging AMD's upcoming 4th generation Graphics CoreNext architecture, codenamed "Polaris." Found in the footnotes of AMD's "Polaris" press-deck, mentioned as an ominous-sounding "Xbox One Polaris," the mention hints at a revision of Xbox One that features an SoC running a "Polaris" based SoC. Microsoft could leverage the energy-efficiency improvements, and possibly upcoming processes, such as 14 nm FinFET, to bring down power-draw, thermal requirements, and possibly cost.
