'''Scorpio Engine''' is a {{arch|64}} [[octa-core]] [[x86]] SoC designed by [[AMD]] and [[Microsoft]] for their ''Xbox One X''. The chip features eight {{amd|Enhanced Jaguar|l=arch}} cores operating at 2.3 GHz and a custom {{amd|Arctic Islands|l=arch}}-based GPU operating at 1.172 GHz. Fabricated on [[TSMC]]'s [[16 nm process|16FF+]], this chip supports 12 (24 for Dev) GiB of 12-channel GDDR5-6800 memory. | '''Scorpio Engine''' is a {{arch|64}} [[octa-core]] [[x86]] SoC designed by [[AMD]] and [[Microsoft]] for their ''Xbox One X''.

=== Yield & redundancy === | === Yield & redundancy === | ||
In normal microprocessors such as typical [[CPU]]s and [[GPU]]s, when a core in the case of a CPU or a shader unit in the case of a GPU has a defect, it's common for manufacturers to disable those affected cores/shaders (typically in a symmetrical way) and [[binning|sell those chips as lower end models]]. Since the Scorpio Engine is only found in the single-specification ''Xbox One X'' machine and its dev kit, [[binning]] is not as flexible. In an attempt to improve yield for the consumer models the Scorpio Engine actually incorporates 11 Compute Units (CUs) in each shader array for redundancy, 10 of them are operational while an 11th one is used as a spare. With 4 shader arrays, there are 4 spares and 40 enabled CUs. If one or a few compute units are faulty but the rest of the chip is fully functional, the spare CUs can be enabled to compensate for this. Fully unlocked Scorpio Engines are incorporated in the dev kits, though in lower volume than the consumer models. | In normal microprocessors such as typical [[CPU]]s and [[GPU]]s, when a core in the case of a CPU or a shader unit in the case of a GPU has a defect, it's common for manufacturers to disable those affected cores/shaders (typically in a symmetrical way) and [[binning|sell those chips as lower end models]].
