Xbox Series X/S received praise from critics for the hardware specifications of the Series X in comparison to older Xbox One models, and Microsoft's emphasis on cross-generation releases, but believed that the games available at launch did not fully leverage the hardware capabilities of the consoles. Microsoft has not officially released sales data for the Xbox Series X/S but stated on July 27, 2021, that they were the fastest-selling Xbox models to-date, and it was estimated that Microsoft had shipped at least 14.6 million units of the two consoles worldwide by June 2022.


History


Initial unveiling and launch

Industry rumors of new Xbox hardware had started as early as June 2018, with Microsoft's Phil Spencer confirming they were "deep into architecturing the next Xbox consoles" at that time. The hardware was believed to be a family of devices under the codename "Scarlett", including a low-cost version following a similar scheme as the

. On July 16, 2020, Microsoft announced that it had ended production of the Xbox One X and all-digital version of the Xbox One S in preparation for the new products. The existence of the Xbox Series S had been speculated prior to the E3 2019 reveal based on a "Project Lockhart", a second, lower-end console that accompanied Scarlett. Confirmation of the Xbox Series S naming was affirmed through early Xbox hardware accessories that some had been able to purchase. Microsoft officially announced the Series S console on September 8, 2020, revealing that it would also be released alongside the Series X in November 2020. Microsoft pointed out that the Series S had been discreetly placed in the background of previous Xbox announcement videos featuring Phil Spencer during July 2020.


Console Hardware

When Microsoft's Xbox development team started work on the successor to the Xbox One consoles around 2016, they had already envisioned the need to have two console versions similar to their Xbox One X and Xbox One S models to meet the needs of different markets. By developing both units in concert, they would be able to make sure games developed would be able to be played on both systems without exception. As has been tradition with past Xbox projects, the consoles were given code names based on cities. The Xbox Series S was named Project Lockhart, based on the city of

As the engineers collected power requirements to meet these specifications, they saw these parts would draw a large amount of internal power (approximately 315  W) and would generate a significant amount of heat. This led to the decision to split the components onto two separate

After accounting for the system software, approximately 13.5 GB of memory will be available for games and other applications, with the system software only drawing from the slower pool. The Xbox Series X target performance is to render games at 4K resolution at 60 frames per second, with the CPU being about four times as powerful as the Xbox One X CPU and the GPU twice as powerful. The Series X can support up to 120 frames per second and can render up to 8K resolution. The Xbox Series X's console form is designed to be unobtrusive and minimalistic.

Xbox Series S

The Xbox Series S is comparable in its hardware to the Xbox Series X, similar to how the Xbox One S relates to the Xbox One X, but has less processing power. While it runs the same CPU with slightly slower clock frequencies, it uses a slower GPU, a custom RDNA2 with 20 CUs at 1.55  GHz for 4 TFLOPS, compared to 12 TFLOPS of the Series X. It ships with 10 GB of RAM, with 8 GB running at 224GB/s primarily to be used with the graphics system and the other 2 GB at 56 GB/s to be used for the other computing functions, and a 512 GB SSD storage unit with a raw input/output throughput of 2.4 GB/s. It does not include an optical drive, thus all games and software must be obtained digitally via

''. Otherwise, the console has the same functions as the Xbox Series X, including ports, expansions, and game support. Microsoft designed the Series S to easily fit inside of a small bag or backpack for portability and travel usage. The Series S unit is about 60% smaller by volume than the Series X, measuring in its vertical orientation. In this orientation, its large side surface features the major exhaust port for active air cooling, similar to the top surface of the Series X; additional vents are then located on the top of the Series S. Like the Series X, the front of the Series S features one USB port and a controller pairing button with an integrated IR receiver. The rear of the console includes the power connector, one HDMI port, two additional USB ports, and an Ethernet port. Like the Series X, the Series S can also be placed horizontally with the exhaust port facing upward to maintain airflow. The Series S launched in a matte white case along with a matching controller, distinguishing it from the matte black that the Series X uses.


Common features


Xbox Velocity Architecture

Both consoles use a new storage solution, the Xbox Velocity Architecture, that includes hardware and software components to improve transfer speeds within the console, reduce the size of digital downloads, and give developers more flexibility. Central to this is the internal storage, a custom

The software provides sampler feedback streaming that aids in loading multiple textures in segments to deal with level of detail rendering, rather than having to read these textures as a whole before using them. The Series S includes a 512 GB SSD (364 GB available) with similar custom hardware and software specifications. All SSD storage on the architecture use a PCI Express 4.0 x2 link. Developers at The Coalition found that, without any changes to their code, '' Gears 5'' loaded four times faster on Xbox Series X than Xbox One X due to the higher throughput on memory and storage and that they would be able to increase this further once they incorporated the new DirectStorage API routines. The consoles support external storage through a proprietary SSD

Later versions included 512 GB and 2 TB versions and were released at the end of 2021. As with the Xbox One, the consoles will also support external USB storage, but only backward compatible games (which can also be transferred directly from an Xbox One console) will be able to run directly from external USB storage. Xbox Series X- and S-native games must be stored on the internal SSD or an expansion card in order to be played, but they can be moved to a USB storage device to save disk space for other games. The DirectStorage API was released in March 2022 for Windows-based computers for graphics cards that support DirectX 12 and NVMe SSDs, though games must be programmed to take advantage of the DirectStorage API.

A feature called "audio ray tracing" will use the graphics ray tracing processors to process spatial audio in the same manner to improve the audio immersion for the player. Another goal for Microsoft was to reduce the effects of input latency in order to improve responsiveness, adding support for HDMI 2.1 Auto Low Latency Mode and Variable Refresh Rate features, and "dynamic latency input" technology—a new input pathway that allows developers to incorporate potential controller lag into their games.

Xbox Wireless Controller and Accessories for Xbox Series X/S

Both the Series X and Series S ship with an updated version of the
Xbox Wireless Controller The Xbox Wireless Controller is the primary game controller for the Xbox One and Xbox Series X/S home video game consoles, also commercialized for its use in Windows-based PCs, and compatible with other operating systems such as macOS, Linux, ...
which was aimed to be more ergonomic to fit a larger range of hand sizes. They include all the same key buttons as the past controllers: two analog joysticks that can be depressed, a circle pad, four action buttons, two system buttons ("View" and "Menu"), the main Xbox home button, two grip triggers (left and right), and two shoulder buttons (left and right). The new controller adds a "Share" button alongside the "View" and "Menu" buttons; pressing "Share" once takes a screenshot, while holding the button begins a Game DVR recording. Microsoft found that by aiming the size to fit an eight-year-old's hands, they were able to make the design fit a larger section of the population; it thus features more sculpted grips, and has reduced and rounded trigger buttons. The D-pad is a new concave design that senior console designer Ryan Whitaker said was a means to merge the normal D-pad style on the standard Xbox One controller and the version on the Elite variant to accommodate a range of playstyles. Small tactile dot patterns have been added to the buttons to help players orient fingers on the controls. The controller continues to use two

, though a rechargeable battery pack is available as an accessory. Microsoft found from focus group studies that players were split nearly 50/50 on the use of batteries versus recharging and thus gave the controller the option to use either. The controller uses the same wireless protocol introduced by the Xbox One, and is backward compatible with existing Xbox One consoles. Existing Xbox One controllers are also compatible with Xbox Series X. The new controller also supports the Bluetooth Low Energy standard allowing it to pair with mobile devices and other hardware supporting that standard, and has internal storage to remember those connections.

According to the UI development team, the Home section loads in about half the time as it did on the Xbox One. Other changes include adding rounded UI elements, a more-readable font for text elements, rearrangement of certain aligned features, and improvements to the sharing functions. These changes were brought to the Xbox One system software, the Windows' Xbox application, and the Xbox mobile application around September 2020. Based on system previews, about 200 GB of space was reserved on the internal drive of the Xbox Series X for system files. Xbox Series S and Series X support "Quick Resume", which allows users to suspend and resume up to three games at once. Games can also be resumed after a reboot of the console. The March 2022 update added the ability to "pin" up to two games to Quick Resume, keeping them suspended unless otherwise closed manually, or the game must be updated.

Xbox Series X/S Games

At launch of the Xbox Series X/S, Microsoft positioned new games to be available for both the Xbox One and the new consoles.

head Matt Booty stated that Microsoft wanted to ensure that those who buy Xbox One consoles prior to the Series X/S launch would still "feel that they made a good investment and that we're committed to them with content." Spencer explained that this approach was about putting the player at the center rather than the console and not "forcing" users to migrate. According to Spencer, this concept is enabled in part by many of the Xbox Game Studios subsidiaries having familiarity with developing also on personal computers, where there is a wide range of hardware targets to meet. The same approach in personal computer game development was taken to make Xbox Series X/S games that could scale down to perform well on the Xbox One consoles while still taking advantage of the new hardware. Game developers were able to optimize existing and newly released Xbox One games as Xbox Series X/S versions to take advantage of improved Xbox Series X/S technologies, with higher graphics

and faster frame rates, ray tracing, and support for the consoles' storage architecture. For some games, further game improvements from the Xbox One version to Xbox Series X version can be made with the capabilities of the Xbox Series X console; games with this support are marketed with an "Optimized for Series X" logo. Microsoft offered a distribution framework known as "Smart Delivery" that will automatically download Xbox Series X/S versions of backwards compatible games for the console when available; Microsoft has positioned this feature at publishers who plan to release Series X- or Series S-specific versions of games after releasing on Xbox One and to users migrating from an existing Xbox One to an Xbox Series console. Microsoft does not restrict the ability for developers to release games that are exclusive to Xbox Series X, but the company has preferred a "soft" transition more in line with

, where developers can target optimal play on higher-end hardware, but still allow the game to be played with reduced fidelity on lower-end hardware (such as older Xbox One consoles). Initially, Spencer suggested that their first-party studios' games would support both Xbox One and Xbox Series X platforms for the "next couple of years", but journalists observed that some of the first-party games introduced in the Xbox Game Showcase in July 2020 omitted mention of the Xbox One, and their websites later updated to omit mention of the Xbox One. While none of these games were believed to be launch titles, they were expected to be released within the window Spencer had previously suggested. This led to Aaron Greenberg, general manager of Xbox Games Marketing, to clarify that these games were being developed for the Xbox Series X first, leaving the choice of adding Xbox One support to their development studios as they went forward. Microsoft has not placed any similar requirements on a soft transition for third-party developers and publishers, allowing them to offer Xbox Series X exclusives or other routes to upgrade from the Xbox One edition of a game, though ''

Backward compatibility

and original Xbox games currently supported through backward compatibility on the Xbox One, thus allowing the new consoles to support four generations of games. To achieve this level of compatibility, Microsoft announced in June 2019 that they would no longer be bringing any additional Xbox 360 or original Xbox games into the Xbox One backward compatibility program, and they would instead be using their manpower to make sure these older games were playable on the Xbox Series X. Backward compatibility is a launch feature, with Microsoft having put more than 500,000 man-hours in validating thousands of games from the supported Xbox One library; Spencer said in December 2019 that he himself had been helping to test backward compatibility games. As Microsoft neared launch, they reopened the means for players to suggest additional games to add to backward compatibility, stating "Resurrecting titles from history often presents a complex mix of technical and licensing challenges, but the team is committed to doing everything we can to continue to preserve our collective gaming legacy." It is possible for advanced graphic processes options not originally programmed into these older games to be worked into the game when played on the console, such as automated

Work done by the Xbox Advanced Technology Group prior to launch was focused on how far into the backward-compatibility library they could take these improvements, including into original Xbox games, adding in features like HDR or improving the framerate of games that may have been programmed to be locked at a specific framerate. Backward compatible games are supported under the Quick Resume feature as well. Cloud saves can be used to migrate from Xbox One, and Microsoft stated that it would also add free cloud saves to the Xbox 360 so it can be migrated to a Series S/X console as well.

, and auto HDR support, but it does not support Xbox One X-specific enhancements. Microsoft is providing tools for developers to check the performance of their Xbox One games on the Series X and S consoles, which can suggest optimizations "as easy as changing three lines of code" to support the improvements in backward compatibility. In February 2021, Microsoft introduced FPS Boost, a feature for select backward-compatible games that the company said can improve the framerate of these titles on the Xbox Series X and Series S by two to four times. This is a feature that Microsoft's engineers must prepare for each game, with five games supported initially and more to be rolled out over time. Microsoft developed FPS Boost after finding that for many backward compatible games, the CPU and GPU on the newer consoles frequently entered their idle states even with the other enhancements in place, and so they sought ways to use the unused processing cycles to further enhance the older games' performance. As of May 2021, about 97 games were updated to support FPS Boost. In March 2021, Microsoft started testing the Auto HDR feature with Windows-compatible games and computers that meet minimal requirements supported through DirectX.

Then, Spencer believed that while the hardware will continue to ship on time, games poised for the release window of Xbox Series X may be delayed due to the pandemic. By August 2020, Microsoft committed to a November 2020 release window for the Xbox Series X, affirming the console's release was still on track. Both the Xbox Series X and Series S consoles launched on November 10, 2020, with the Series X priced at , , and and the Series S priced at , , and . In China, the systems would release on June 10, 2021.

Microsoft will continue its Xbox All-Access financing plans (which bundle the hardware, Xbox Live Gold, and Xbox Game Pass as part of a monthly payment plan) for the Series X. Current All Access plans with the Xbox One will include routes to upgrade to the Xbox Series X, and Spencer states that there will be similar upgrades from the Xbox Series X in the future.

Reception

At launch, critics praised the new console hardware and commented positively on its improved graphics, reduction of loading times, and strong backward compatibility support, but, due to the lack of any console exclusives, remained hesitant of the console's true power. Because of this, at launch, many did not feel these consoles truly represented the next generation of home consoles. The lack of significant launch-day exclusive titles designed to show off the new hardware capabilities, as well as the familiar controller shape and user interface, was considered by some to be disappointing given the next-generation focus of Sony's PlayStation 5. The Series X was generally considered the better unit when compared to the Series S, as the computation and space limitations of the latter made it a less user-friendly experience to navigate but still otherwise functional.

He also felt that migrating from an older Xbox One was easier than migrating from PS4 to PS5, citing Smart Delivery, automatic synchronization of save data, and maintaining the same user interface.


Sales

Microsoft announced that the Xbox Series X/S was the biggest Xbox console launch, with more consoles sold in more countries in its first 24 hours than any previous Xbox. The record was previously held by the Xbox One, which sold more than one million units at launch. The Xbox Series S has attracted a higher percentage of new Xbox players than any previous Microsoft consoles. Microsoft's CEO, Satya Nadella, would affirm in an earnings call on July 27, 2021 that the Series X and S consoles were the fastest selling Xbox consoles ever. Microsoft has not revealed the exact sales numbers of the Xbox Series X/S, having last revealed sales figure for Xbox consoles in 2014. However, estimates from industry analysts and exact sales from specific regions are available. Daniel Ahmed, a Niko Partners analyst, has provided estimates for the worldwide sell-through of the Xbox Series X/S. The combined worldwide sales of the Xbox Series X and Series S would have reached 3.5 million by December 31, 2020. Sales would increase to 6.5 million by June 30, 2021, outpacing the 5.7 million units sold of the Xbox One and the 5 million units of the Xbox 360 in the same timeframe. Sales worldwide are estimated to have reached 8 million by September 30, 2021, and 12 million units by the end of 2021. Certified sales data are available in certain regions through providers, such as GfK in Europe and

in Japan. In the UK, 155,000 units were sold on launch day, two-thirds of which were Xbox Series X consoles. Sales in the region would reach 310,000 by the end of 2020, and 1 million by the end of 2021. The Series X variety accounted for 43% of all the Xbox Series consoles sold over 2021 in the UK. There were 16,247 Xbox Series X and 4,287 Xbox Series S systems sold throughout Japan during the launch week, for a combined total of 20,534 units sold. Sales in Japan would cross 116,000 in November 2021, outselling the lifetime Japanese sales of the Xbox One in under a year. There were 10,500 Xbox Series X and 3,600 Xbox Series S systems sold throughout Spain during the launch week for a combined total of 14,100 units sold. By the end of 2020, 30,850 Xbox Series X and S systems had been sold in Spain.

caused the supply of Xbox consoles to fall short of demand. Upon launch, with high demand outstripping supply for both models, the consoles almost immediately sold out across all retailers and in all markets. Spencer stated that they had gotten a later start on manufacturing the console in mid-2020 as they were waiting for key AMD chip technology to be in place, which reduced the availability of supply at launch, and though they had reached full production capacity by launch, they were still rushing to meet sales demand, as well as having made projections on proportions of Series X versus Series S sales. Xbox chief financial officer Tim Stuart has stated that shortages were likely to persist through the first quarter of 2021, but their supply chain was expected to be up to full capacity by the second quarter of the calendar year. The shortage of supply at launch led to scalping on Internet marketplace sites, with consoles going for as high as . Starting in May 2021, Microsoft offered those in the Xbox Insiders program the ability to sign up for its Console Purchase Pilot program to be placed on a priority list to purchase an Xbox Series X or Series S directly from Microsoft, though only a limited number of units will be offered through this program. Although Microsoft was unable to produce enough units to satisfy demand during 2021, the revenue from consoles increased over prior years, due to higher unit prices and large volumes sold.
