Platform: Xbox Series X/S

Xbox Series X/S

The Xbox Series X and Series S are Microsoft’s fourth-generation home consoles, launched together in November 2020. They arrived at a tricky time for the world and a pivotal moment for gaming, promising faster load times, higher frame rates, and a different strategy built around services such as Game Pass. The two machines share one platform and most features, yet they approach players with distinct price points and power profiles. The flagship Series X targets 4K gaming and uncompromised performance. The smaller, more affordable Series S focuses on a lower resolution target with the same modern feature set and strong value.

If you want the elevator pitch in one breath: these consoles combine a custom AMD Zen 2 CPU, RDNA 2 graphics, NVMe SSD storage, and the Xbox Velocity Architecture to smooth out the drudgery of waiting and put more time into actually playing. Whether you opt for the black monolith of the Series X or the compact white slab of the Series S, the core experience is unmistakably Xbox. And it hinges on that blend of power, backward compatibility, and a subscription everywhere ethos that has reshaped how many people discover games.

For basic specs and official materials, the product pages for the Xbox Series X and Xbox Series S are a handy starting point. A broader historical overview is captured well on Wikipedia’s page on Xbox Series X and Series S.

Launch context and early story

The Series X/S family launched on November 10, 2020. Hardware teams had been building toward this moment since the Xbox One X experiment in 2017 proved that mid-cycle refreshes and performance-first design could attract enthusiasts. The new consoles were conceived as a clean break from the Jaguar-era CPUs of the Xbox One generation, with the SSD and modern GPU features like hardware-accelerated ray tracing at the center of the pitch.

The launch happened amid chip shortages and supply-chain chaos. Securing a console was a small triumph by itself for months. That scarcity shaped the early narrative, masking demand and making comparisons to rival platforms messy. Meanwhile, Microsoft leaned into a cross-generation approach, promising that major first-party releases would run on both new and older hardware for a while. Some observers loved the player-friendly stance that avoided leaving anyone behind overnight. Others worried that the shared target would hold next-gen back. The truth was more nuanced. Cross-gen design helped ease the transition and also shone a spotlight on the unique role of the Series S as the affordable entry point to next-gen features.

A few notable decisions set the tone. Microsoft delayed Halo Infinite from the console’s launch to 2021 after a lukewarm public demo, signaling a willingness to wait rather than ship a compromised flagship. And from day one, Game Pass integration was front and center, framing the console less as a box that sells games and more as one of many access points to a growing library, also including PC and cloud devices.

Design and hardware philosophy

You can tell the two consoles share DNA but chase different priorities. The Series X is a compact tower with a single large axial fan on top, a vapor chamber for cooling, and a footprint designed to minimize acoustics. It can sit vertically or horizontally, but its look feels happiest standing up. The green-accented ventilation at the top became a signature look, and it is one of the quietest high-performance consoles ever made. I have seen gaming PCs go to thermal war while a Series X stays almost whisper-quiet.

The Series S shrinks everything. It is strikingly small, with a circular black vent on a white body. No disc drive, no 4K target for most games, and a smaller SSD. Yet it supports the same SSD-based streaming architecture, the same low-latency pipeline, and the same controller features. It is the console you can stash on a small shelf or toss into a bag for travel, and it has often been priced aggressively to reach a wider audience.

Microsoft extended the lineup in mid-2024 by offering more storage and form factor options, including a 1 TB Series S in white and a 1 TB all-digital Series X in white, as well as a limited 2 TB special edition Series X. Those variants underline the modularity of the strategy: let players pick the price, storage, and optical drive configuration that fits them.

Core specs and technologies

Paper specs never tell the entire story, but they do frame expectations. The Series X is built for 4K and higher fidelity, while the Series S aims for 1080p to 1440p with high frame rates.

What follows is a compact, practical summary of the essentials, without drowning you in motherboard trivia:

Before listing the key items, it helps to understand that both consoles share a custom AMD SoC with Zen 2 CPU cores and RDNA 2 graphics, plus dedicated hardware blocks for decompression and streaming. That common foundation is why features like Quick Resume, Auto HDR, and hardware ray tracing show up on both.

  • CPU: 8-core AMD Zen 2, up to 3.8 GHz on Series X and roughly 3.6 GHz on Series S, with simultaneous multithreading supported
  • GPU: Custom RDNA 2, approximately 12 TFLOPS on Series X with 52 compute units at around 1.825 GHz, and about 4 TFLOPS on Series S with 20 compute units at around 1.565 GHz, both with variable rate shading and hardware ray tracing
  • Memory: Series X 16 GB GDDR6 on a split bus with roughly 10 GB high bandwidth and 6 GB standard, Series S 10 GB GDDR6 with a similar bandwidth split optimized for its target resolution
  • Internal storage: Custom NVMe SSD, 1 TB on Series X and 512 GB on Series S at launch, with later models offering 1 TB for Series S and up to 2 TB on special editions of Series X
  • Optical drive: 4K UHD Blu-ray drive on Series X models with disc support, no drive on Series S and all-digital Series X variants
  • Video output: HDMI 2.1 features including up to 4K 120 Hz output, variable refresh rate, and auto low latency mode, with 8K media support on paper for specific scenarios
  • Audio: Spatial audio formats such as Dolby Atmos and DTS:X supported, with HDMI eARC setups depending on the connected TV or receiver

The headliner behind the scenes is the Xbox Velocity Architecture, a package of technologies designed to feed the GPU with data faster and more efficiently. It combines the NVMe SSD, hardware-accelerated decompression, and features like Sampler Feedback Streaming so textures can be streamed in with less waste. For players, that translates to faster loads, smoother asset streaming, fewer texture pop-ins, and the almost magical Quick Resume feature that parks multiple games and lets you jump back into exactly where you left off.

Storage and expansion

Storage is where new-gen aspirations meet the reality of file sizes. Modern games are heavy, especially in 4K, and even with texture compression there is only so much you can do. Microsoft standardized a simple, proprietary expansion solution that behaves like the internal SSD and supports all next-gen features. You plug a Storage Expansion Card into the slot on the rear and it appears as a continuation of your main storage. Over time, capacities expanded beyond the initial 1 TB option, and pricing came down as more vendors joined.

External USB drives are also supported for backward compatible games. Many players use a large, inexpensive USB HDD for Xbox One and older titles, while keeping newer Series-optimized games on the internal or expansion SSD. You can also "cold store" new-gen games on a USB drive and move them back to the internal SSD when you want to play, which is faster than re-downloading.

A small tip from experience: if you are the kind of player who rotates across a handful of big games and likes Quick Resume, more SSD space reduces the number of times you need to manage your library. The 1 TB Series S or a 1 TB expansion card can be a sweet spot.

Controller and accessories

The standard Xbox Wireless Controller that ships with Series X/S looks familiar but benefits from the kind of iteration that matters in daily use. The shape is slightly refined for more hand sizes, the grips are subtly textured, the triggers have a better surface, and a satisfying Share button sits at the center for quick screenshots and clips. The hybrid D-pad takes design cues from the Elite controller and is great for 2D games and quick inputs. Connectivity uses Xbox Wireless and Bluetooth for PCs and mobile devices, and there is a USB-C port on the front for wired play and charging if you use a rechargeable pack.

Microsoft kept support for AA batteries, which some people love for flexibility and others dislike because it is not rechargeable out of the box. Official rechargeable battery packs are available, and many third-party options exist. The decision also ensures that accessories like the excellent Elite Series 2 controller and the Xbox Adaptive Controller integrate seamlessly with Series X/S.

Beyond controllers, there are headsets with low-latency Xbox Wireless connections, steering wheels, fight sticks, and the signature storage expansion cards. Later in the generation, more colors and limited designs arrived, and the ecosystem of flight sim gear grew as Microsoft Flight Simulator matured on the platform.

System software and quality-of-life features

The Xbox dashboard runs a Windows core tailored to consoles. It is snappy, supports fast resume from standby, and integrates with the Xbox app on mobile and PC for remote installs and content management. Over the life of the platform, the UI has seen regular updates that improve speed, personalization, and discovery. Night Mode, quick settings overlays, and more granular HDR toggles are examples of tweaks that came from listening to user feedback.

Quick Resume deserves a special mention. The system can freeze multiple game states on the SSD and return to them in seconds, even after a full reboot or system update in many cases. Early on, not every game played nicely with it, but updates significantly improved reliability. When it works, it feels like alt-tabbing on a PC, except you are hopping across completely different worlds.

On the video side, support for variable refresh rate and 120 Hz output benefits fast-paced games and smooths over frame time hiccups, provided your TV or monitor supports those features. Dolby Vision gaming support rolled out for many displays, especially helpful for consistent HDR tone mapping without manual adjustment.

Another welcome change is "cloud install before download" integration for Game Pass Ultimate subscribers. With Xbox Cloud Gaming available directly on the console, you can try a game instantly via streaming while the local copy downloads in the background. It is not always a perfect substitute for native performance, but it is fantastic for sampling.

Backward compatibility and enhancements

Backward compatibility is one of the pillars of the Series X/S value proposition. Thousands of Xbox One titles run on the new consoles, many with improved load times and more stable performance. That library includes a curated catalog of Xbox 360 and original Xbox games that were already backward compatible on Xbox One, all benefiting from the faster hardware.

Two system-level enhancements stand out:

  • Auto HDR: This feature applies HDR to SDR games at the system level for a broader contrast range on compatible displays. While it is not a replacement for native HDR artistic intent, it often adds pleasing depth to older games without washing out colors.
  • FPS Boost: Selected Xbox One titles received frame rate boosts with no code changes required from the original developers. Doubling a game from 30 fps to 60 fps or from 60 to 120 can make a huge difference, especially in shooters and platformers.

Many games also run at higher resolutions or with improved anisotropic filtering just by virtue of the new hardware. Some Xbox One titles shipped "Optimized for Series X|S" updates that add features like ray tracing, better textures, or higher frame rate modes. I still smile when booting up a 360-era classic that loads in seconds and plays more smoothly than it ever did on original hardware.

Games and standout experiences

Exclusives are different in the Xbox era because Microsoft releases first-party games on both console and PC at the same time, with Game Pass day-one availability. That can make "exclusive" feel like a fuzzy word, yet the platform still has a set of defining experiences.

Halo Infinite eventually arrived in late 2021 with a strong multiplayer component and an open-structure campaign. The shooting is excellent, movement fluid, and the grappleshot quickly became one of those mechanics that ruins other shooters for you. The launch was not perfect, but the core gameplay holds up and the multiplayer has seen meaningful iteration.

Forza has arguably become the new reference. Forza Horizon 5 (2021) set in Mexico shines with 60 fps on both consoles and a 120 fps mode on Series X. It is one of the best "show someone why you bought this console" demos. Forza Motorsport returned in 2023 with a new technical baseline and modern tire and physics models, emphasizing a more serious approach. Both illustrate how well the platform handles high frame rate driving games.

Microsoft Flight Simulator arriving on Series X/S in 2021 felt like a minor miracle. The engine was rebuilt to leverage DirectX 12 and the Velocity Architecture. It streams the world from the cloud, uses photogrammetry in many cities, and still looks incredible on a living room TV. With a good headset and a bit of imagination, it is a travel machine.

On the single player side, Starfield landed in 2023 as a massive space RPG, with scope and systems that invite tinkering. Pentiment and Hi-Fi Rush showed the creative range of the first-party portfolio. Pentiment is a historical narrative adventure unlike anything else in the catalog. Hi-Fi Rush popped up as a surprise release, combining rhythm and character action with a bold art style and a lovable cast. And in 2024, Senua’s Saga: Hellblade II pushed audiovisual fidelity and binaural audio to striking heights, a moody showcase for high dynamic range visuals.

Sea of Thieves, Gears 5, and Ori and the Will of the Wisps all benefited from Series optimizations like 120 Hz modes and lower latency, proving that older gems can gain new life. Third-party support has been strong as well, from the usual multiplatform blockbusters to indies that love the visibility that Game Pass can bring.

Because Microsoft acquired ZeniMax/Bethesda in 2021 and closed on Activision Blizzard in late 2023, the content pipeline expanded. How and when those franchises appear on competing platforms is a strategic question that evolves, but on Series X/S the net effect is obvious: the library available within Game Pass is broader and the long-term first-party slate more predictable.

Services and the changing ecosystem

If there is one idea that most differentiates Xbox in this generation, it is the service-centric approach. Xbox Game Pass offers a rotating library of hundreds of games for a monthly fee, with first-party titles available on day one and a steady stream of notable third-party additions. There are tiers for console, PC, and Ultimate, with Ultimate bundling online multiplayer and cloud gaming. The service has set expectations for subscription value in gaming in a way that echoes how streaming reshaped television, albeit with a more complex relationship to ownership and curation. You can read the latest on tiers and availability on the Xbox Game Pass page.

Smart Delivery is another player-friendly feature. If you buy a game once, you get the best version for the Xbox you are playing on, with saves and purchases carrying along. It sounds obvious, but it prevented a messy situation where players would have to pick and pay for the right SKU or risk fragmentation.

Cloud gaming on console closed an important loop. Being able to boot a Game Pass game instantly in the cloud, test the opening hour, then continue the downloaded native version when ready is a quality-of-life improvement that makes discovery painless. It is also handy for friends visiting who want to try something without waiting for a 100 GB download.

Competing landscape and market performance

Comparisons to PlayStation 5 dominated early conversations. Both platforms switched to SSDs, modern GPUs, and high frame rate targets, and both had to fight through shortages. The Series X was framed as the most powerful console by raw compute numbers, while the PS5 pushed developer-friendly tools and bespoke I/O solutions. Real-world game performance varied by title and engine maturity across the first two years as toolchains and experience caught up.

The Series S added an unusual dimension. It allowed Microsoft to hit a more accessible price and serve 1080p to 1440p displays well, but it also created a lower common denominator that developers had to consider for optimization. Some studios voiced concerns that split targets increased workload, especially for memory-bound scenarios. Over time, techniques like dynamic resolution, temporal upscaling, and memory layout optimizations eased those pains, but the discussion surfaced regularly.

Sales-wise, Microsoft is famously coy with granular numbers these days. Public reports, third-party estimates, and regional analyses suggest the Series X/S combined have sold well into the double-digit millions, with performance varying by market and time frame. The Series S has punched above its weight in some regions and during promotions. The result is a healthier competition for players, with frequent multi-platform releases and a service debate that keeps everyone on their toes.

Developer impact and tools

Under the hood, the Xbox Game Development Kit unified Xbox One and Series X/S development workflows, so teams could target multiple device capabilities through one SDK and feature gating. The consistency of the PC-like environment helped many studios, while the two memory footprints and GPU targets required careful content scaling. The hardware decompression blocks and Sampler Feedback helped developers stream high-resolution texture data without blowing memory budgets.

DirectX 12 Ultimate features such as variable rate shading and mesh shaders slowly made their way into production pipelines through this generation. Adoption follows the usual curve. Big engines like Unreal and Unity exposed features incrementally, and first-party games often served as testbeds. Tools matured quickly, and the platform holders kept sending firmware and SDK updates to smooth CPU scheduling, GPU timeout behavior, and I/O tuning.

For smaller developers, the ability to launch on Game Pass brought discoverability and a baseline audience. The flip side is the ongoing conversation about sustainability, revenue models, and long-term catalog value. As someone who loves offbeat indie experiments, I will admit Game Pass is where I have discovered many of them on console.

Accessibility and sustainability

Xbox has been a leader in accessibility for years, and the Series generation continued that trend. System-level features such as Copilot input, speech-to-text, text-to-speech, remapping, and color filters are available. The Xbox Adaptive Controller remains a landmark device, making the platform flexible for players with diverse needs. Many first-party titles launched with robust accessibility menus, and the developer guidelines became more visible.

On sustainability, Microsoft added energy-saving options by default, reduced power draw in standby, and built a carbon aware update system that schedules downloads to align with cleaner energy availability in your region where possible. Packaging and materials saw more recycled content, and the company published periodic updates with energy usage data and guidance. None of this single-handedly solves the environmental impact of electronics, but the incremental changes matter at scale.

Industry impact and legacy

Zoom out, and the Series X/S generation will likely be remembered for three intertwined shifts. First, the SSD and new I/O paradigms shortened load times and enabled game designs that assume near-instant asset availability. Second, the normalization of 60 fps on consoles made fluidity a new baseline for many genres, with 120 Hz becoming a prestige option. Third, the service layer grew from an optional add-on to a primary way many players engage with new releases.

At a business model level, Microsoft’s approach pressured the industry to think differently about subscriptions, launch windows, and cross-platform support. It pushed Sony to accelerate its own subscription tiers and PC releases, and it re-opened debates about ownership versus access. For players, the practical takeaway is more choice. You can buy a disc or a digital copy and own it. You can subscribe and sample widely. You can play on console, PC, or the cloud. Each has trade-offs, but the options are there.

Microsoft’s studio acquisitions reshaped expectations about what franchises sit under the Xbox umbrella. Bethesda’s portfolio and Activision Blizzard’s catalog now sit within the same corporate family as Halo and Forza. How exclusivity is handled across generations will have ripple effects across retail, esports, and platform loyalty. Xbox chose to frame itself as a service and ecosystem rather than a single box, and that identity is now baked into Series X/S and whatever follows.

Curiosities and anecdotes

No exploration of Series X/S is complete without a few delightful oddities. When the Series X reveal hit the internet, its silhouette invited jokes about it looking like a mini fridge. Microsoft embraced the meme. They produced an official Xbox Series X Mini Fridge, which sold out and restocked in waves. It is a bit loud, perfectly silly, and a lovely example of a company willing to laugh with the community.

Quick Resume also spawned fun social dynamics. There is something charming about bouncing from a sweaty Forza session to a quiet Pentiment reading interlude in seconds, then hopping into a co-op Sea of Thieves run when friends ping you. It turns the console into a multi-genre jukebox, and if you are the indecisive type, it might be your favorite feature.

On the Series S side, the little white box became a travel companion for many. Toss it into a backpack with a controller and an HDMI cable and you have an entire library ready to go at a relative’s house or a hotel room. Paired with cloud saves and Game Pass, it almost feels like a portable console, just add a TV.

Notable games at a glance

There is no need to reduce the library to a numbered list, but it helps to name a few icons that showcase different strengths of the platform.

  • Halo Infinite: Precise gunplay and slick movement, a multiplayer live service that kept evolving, and a sandbox campaign that made the grappleshot a star.
  • Forza Horizon 5: Bright, fast, and welcoming, with excellent 60 fps performance and one of the best photo modes in the hobby.
  • Forza Motorsport: Technical racing rebuilt for the generation, with deeper physics and a path for long-term updates.
  • Microsoft Flight Simulator: A world-scale simulation reimagined for the living room, with visuals that still make new players do a double take.
  • Starfield: A classic Bethesda-style RPG made for wandering, tinkering, and modding, with a strong identity on Series hardware.
  • Hi-Fi Rush: A surprise drop that combined rhythm and action with a bold aesthetic, proving that Game Pass can amplify creative bets.
  • Pentiment: A narrative adventure with a distinctive art style and writing, a reminder that not every flagship needs bombast.
  • Sea of Thieves, Gears 5, Ori and the Will of the Wisps: Examples of cross-gen games that shine with higher frame rates and richer image quality on Series consoles.
  • Senua’s Saga: Hellblade II: An audiovisual benchmark that leans hard on binaural audio and cinematic presentation.

Buying tips and common questions

People often ask whether to choose Series X or Series S. The simple rule is to align with your display and habits. If you own a 4K TV, love big visual modes, and want a disc drive, the Series X is the better fit. If you play on a 1080p or 1440p screen, care more about frame rate than pixel count, and want the best price, the Series S is a great pick. Storage is the second key variable. Consider how many giant games you rotate through at once. Expansion cards add cost, but they are plug-and-play and maintain full performance.

Another frequent question is whether the Series S will hold the generation back. In practice, developers have shipped impressive results on both machines by scaling resolution, texture budgets, and effects, while keeping features like ray tracing or high frame rates where appropriate. The Series S is not a 4K machine, but it delivers a robust next-gen experience, especially when paired with a 120 Hz display.

Finally, does Game Pass replace buying games? For many, it changes the mix. You might discover and finish more games than ever through the subscription, then choose to purchase favorites to keep permanently. It is less about replacement and more about a different balance between sampling and collecting.

Where Series X/S stands today

As the generation matures, the Xbox Series X/S platform has settled into a confident identity. The hardware is capable, the services are compelling, and the library keeps growing with a blend of big technical showcases and distinctive smaller works. The consoles weathered a difficult launch era with grace, improved steadily through updates, and found their audience across different price points.

Whether you are chasing 120 fps in a competitive shooter, cruising through beautiful open roads, flying over your hometown from the stratosphere, or getting lost in an indie narrative, the Series X/S machines turn the TV into a canvass with minimal friction. And because your existing Xbox library carries forward and your saves float across console, PC, and cloud, the platform feels cohesive in a way that rewards long-term investment.

If you want to continue exploring, the official pages for Xbox Series X and Xbox Series S outline features, bundles, and accessories, while Wikipedia’s overview provides a useful historical and technical summary. Most importantly, there is nothing stopping you from opening the store, downloading something you have never heard of on Game Pass, and letting the platform do what it does best: surprise you.
