==Hardware revisions==
===Xbox One S===
On 13 June 2016, during its E3 2016 press conference, Microsoft unveiled '''Xbox One S''', a revision of the original Xbox One hardware with a streamlined form factor. Its new casing is 40% smaller than the original design and supports vertical orientation with a stand. The capacitive power and eject keys were replaced by physical buttons,<ref name="techradar-onesreview" /> the side USB port and controller sync button were moved to the front of the console, and its power supply is integrated into the console's casing rather than sitting externally. Xbox One S requires a USB adapter to attach a Kinect sensor, as it no longer includes the proprietary port used on the original model.<ref name="verge-ones" /> A free USB adapter was provided by Microsoft to Kinect owners who registered their ownership of Kinect and Xbox One S online, but this promotion ended in March 2017. Although Microsoft stated that it would eventually bundle the adapter with standalone Kinect units, this has yet to occur.<ref name="verge-ones" /><ref name="polygon-nomoresensor">{{cite web|title=Microsoft ends free Kinect adapter promotion for Xbox One S owners|url=http://www.polygon.com/2017/4/5/15192792/xbox-one-s-kinect-adapter-free-microsoft|website=Polygon|publisher=Vox Media|accessdate=April 5, 2017}}</ref>

Xbox One S is available in 500 GB, 1 TB, and "special edition" 2 TB models, which originally retailed at US$299, $349, and $399 respectively.

===Xbox One X===
During its E3 2017 press conference, Microsoft unveiled '''Xbox One X''', a high-end version of the Xbox One console which released on 7 November 2017. First teased at E3 2016 under the codename "Project Scorpio", Xbox One X features upgraded hardware that is designed primarily to play games at 4K resolution, and [[Wikipedia:Supersampling|supersampling]] to provide graphical improvements on high-definition displays.<ref name="verge-onexunveil" />

Xbox One X's design is a revision of the Xbox One S hardware, but further streamlined.<ref name="verge-xboxonexenhanced" /> It uses a system-on-chip (SoC) known as ''Scorpio Engine'', which incorporates a 2.3&nbsp;GHz octa-core CPU, and a Radeon GPU with 40 Compute Units clocked at 1172&nbsp;MHz, generating 6 [[wikipedia:Teraflops|teraflops]] of graphical computing performance. It also includes 12 GB of [[wikipedia:GDDR5|GDDR5]] RAM, 9 GB of which is allocated to games.<ref name="engadget-moreram">{{cite web|title=Xbox exec reveals Scorpio has 9GB of RAM available for games|url=https://www.engadget.com/2017/06/09/xbox-one-project-scorpio-memory/|website=Engadget|accessdate=June 12, 2017}}</ref> Scorpio Engine's CPU utilizes a custom platform designed to maintain compatibility with the Jaguar CPU of the original Xbox One, but with a 31% increase in performance; the custom platform is unrelated to AMD's current Ryzen architecture. The console will feature a vapor chamber method of cooling for the SoC, and motherboards will be tailored to the exact voltage needs of each individual Scorpio SoC to optimize their output and energy usage.<ref>{{cite web | url = http://www.eurogamer.net/articles/digitalfoundry-2017-project-scorpio-tech-revealed | title = Inside the next Xbox: Project Scorpio tech revealed | first=  Richard | last= Leadbetter | date = April 6, 2017 | accessdate = April 6, 2017 | work = Eurogamer }}</ref> The console will also support AMD's FreeSync technology on compatible displays.<ref>{{Cite web|url=https://arstechnica.com/gaming/2017/06/xbox-one-x-scorpio-games-explainer-video/|title=Xbox One X: Everything you need to know|work=Ars Technica|access-date=2017-08-04|language=en-us}}</ref>

Xbox One X will be compatible with all existing Xbox One software and accessories.<ref name="verge-scorpio">{{cite web|title=Project Scorpio is a 4K-capable, VR-ready Xbox One launching next fall|url=https://www.theverge.com/2016/6/13/11890842/microsoft-xbox-project-scorpio-virtual-reality-e3-2016|first=Andrew|last=Webster|website=The Verge|publisher=Vox Media|accessdate=June 13, 2016}}</ref> Games marketed as ''Xbox One X Enhanced'' have specific optimizations for graphical fidelity on the console's hardware, while separate iconography is being used to denote games that natively run at 4K resolution, or support HDR.<ref name="polygon-xb1enhanced">{{cite web|title=Microsoft introduces branding for Xbox One X improvements|url=https://www.polygon.com/e3/2017/6/13/15796216/xbox-one-x-enhanced-4k-hdr-branding|website=Polygon|accessdate=June 14, 2017}}</ref> Existing games may receive updates to enhancements or additional 4K support for Xbox One X.<ref name="verge-onexunveil" /><ref name="verge-xboxonexenhanced">{{cite web|title=Look for these Xbox One X logos to know you’re getting enhanced 4K and HDR games|url=https://www.theverge.com/2017/6/12/15780976/microsoft-xbox-one-x-enhanced-games-logos-4k-hdr-support|website=The Verge|accessdate=June 12, 2017}}</ref> So far, ''[[Sonic Forces]]'', ''[[Team Sonic Racing]]'', and ''[[Sonic Generations]]'' benefit from such enhancements. After the launch of the [[Xbox Series X and Series S]], the ''Xbox One X Enhanced'' label has since been dropped, though some titles released afterwards can still be enhanced on the Xbox One X, such as ''[[Sonic Colors: Ultimate]]''.

The Xbox One X has been said to be a competitor to the [[PlayStation 4 Pro]], a hardware update of the PlayStation 4 released in late-2016 that similarly focuses on 4K gaming and improved virtual reality performance, although Phil Spencer stated that the PlayStation 4 Pro's competition is instead the Xbox One S.<ref>{{cite web|last1=Warren|first1=Tom|title=Xbox’s Phil Spencer: PS4 Pro is an Xbox One S competitor, not a true 4K console|url=https://www.theverge.com/2017/6/13/15790162/microsoft-phil-spencer-xbox-one-x-vs-ps4-pro-interview|website=Verge|accessdate=June 14, 2017}}</ref>
