<P> Nick Pino of TechRadar was mostly positive, considering the Xbox One S to be "the pinnacle of what Microsoft set out to create three years ago", but noting regressions such as the lack of Kinect port (which was interpreted as being "one last kick in the pants for all the gamers forced into buying the more expensive console bundle two short years ago"), and the lack of 4K content sources beyond Blu - ray, Netflix, and YouTube . Visual improvements were noted on games such as Fallout 4 and Rise of the Tomb Raider when upscaled to 4K . Concerns were shown that the revised hardware and HDR support would lead to fragmentation of Xbox One's ecosystem, as not all users will necessarily experience a game the same way . </P> <P> Dieter Bohn of The Verge praised the Xbox One S's revised design as being "svelte and good - looking", noting its smaller form factor and the lack of power brick . The Xbox One S was also praised for being the cheapest 4K - compatible Blu - ray Disc player on the market, but it was argued that consumers were "(not) as eager to upgrade to 4K Blu - rays as they were to DVDs back in the day . Especially when 4K streaming boxes can be purchased for much less ." The lack of HDR - compatible games available on - launch was panned, as well as Microsoft's choice of the standard over Dolby Vision (which was the only HDR standard supported by the reviewer's 4K television). Bohn concluded that the Xbox One S would appeal best to new owners or those who wish to leverage its HDR and 4K support, but recommended that existing owners hold off until the release of Xbox One X in 2017 . </P> <P> During its E3 2017 press conference, Microsoft unveiled Xbox One X, a high - end version of Xbox One with upgraded hardware and a further - streamlined form factor . First teased at E3 2016 under the codename "Project Scorpio", Xbox One X was released on November 7, 2017, with a 1 TB model priced at US $499, and a limited, pre-order exclusive "Project Scorpio Edition", with a dark gradient finish, vertical stand brace and green "Project Scorpio" inscriptions on the console and bundled controller . </P> <P> Xbox One X features upgraded hardware that is designed primarily to render games at 4K resolution, and provide performance improvements for existing games; they can be displayed at full resolution on 4K displays, or supersampled for lower resolutions displays . It uses a system - on - chip (SoC) known as Scorpio Engine, which incorporates a 2.3 GHz octa - core CPU, and a Radeon GPU with 40 Compute Units clocked at 1172 MHz, generating 6 teraflops of graphical computing performance . It also includes 12 GB of GDDR5 RAM, 9 GB of which is allocated to games . 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 uses a vapor chamber method of cooling for the SoC, and motherboards are tailored to the exact voltage needs of each individual Scorpio SoC to optimize their output and energy usage . The console also supports AMD's FreeSync technology on compatible displays . </P>
