Choose Xbox Series X if you need native 4K gaming, an optical drive for eligible discs, or the larger 2TB storage configuration. Choose Xbox Series S if you are happy with an all-digital library and a console designed around 1440p output, with 512GB and 1TB configurations available. Both support the same Xbox ecosystem features, including Quick Resume, Smart Delivery, backward compatibility, HDMI 2.1, and frame rates up to 120 FPS when a game and display support them.
This comparison uses Microsoft’s US product information current in October 2026. Model lineups, storage configurations, prices, stock and availability can differ by market, so verify the exact edition sold in your region.
Xbox Series S vs. Xbox Series X: what is the difference?
The most important differences are display target, optical-drive support and the storage options attached to each edition.
| Decision axis | Xbox Series S | Xbox Series X |
|---|---|---|
| Design target | 1440p gaming, with the ability to upscale to 4K | Native/true 4K gaming target |
| Frame-rate ceiling | Up to 120 FPS with supported content and a compatible display | Up to 120 FPS with supported content and a compatible display |
| Optical drive | None; digital games only | Included on specified editions; an all-digital edition is also listed |
| Internal storage configurations | 512GB or 1TB SSD | 1TB or 2TB SSD |
| Storage expansion | Series X|S Storage Expansion Card; USB 3.1 external HDD support is listed | Series X|S Storage Expansion Card; USB 3.1 external HDD support is listed |
| Shared platform features | Quick Resume, Smart Delivery, backward compatibility and Xbox One accessory support | The same features, subject to game and accessory conditions |
Microsoft’s own summary is precise: Series X displays games in native 4K and is available with a UHD Blu-ray player, while Series S is designed for disc-free 1440p gaming and can upscale to 4K. That does not mean every Series X game renders at 4K or every Series S game renders at 1440p; the title, mode and display determine the result.

Is Xbox Series S as powerful as Series X?
No. Series X is the more capable rendering machine, but the available official figures do not establish a universal percentage performance gap. Microsoft lists the Series X GPU at 12 TFLOPS, a manufacturer specification rather than an independent benchmark. The official comparison material does not expose every Series S processor figure, so it would be misleading to turn theoretical specifications into a promise that one console runs every game at a fixed frame rate or resolution advantage.
What the published targets mean
- Series X: Microsoft identifies a true/native 4K gaming target and a performance target of up to 120 FPS.
- Series S: Microsoft describes it as designed for 1440p, with the ability to upscale an output signal to 4K.
- Both: “Up to 120 FPS” requires a game that offers that mode and a display capable of showing it. It is a ceiling, not an all-games guarantee.
A game can use a dynamic resolution, separate quality and performance modes, or a frame-rate cap chosen by its developer. Updates can also change those modes. If one particular game matters to you, check that game’s current Series S and Series X support rather than buying on a console-wide promise.
Resolution, 4K and 120 FPS
Native 4K versus 4K upscaling
Series X is the appropriate choice when your priority is a native 4K target on a 4K television or monitor. Series S is optimized for 1440p and can upscale to a 4K output signal. Upscaling lets a 4K display receive a higher-resolution signal, but it is not the same as a game rendering every frame natively at 3840×2160.

Microsoft’s wording describes the console design targets; it does not certify a single resolution for every title.
What you need for 120 FPS
Both families advertise up to 120 FPS. To see a supported 120-FPS mode, you need all three of the following:
Rank #2
- What's in the box: Xbox Series X console, 1 Xbox Wireless Controller - Carbon Black, Ultra High Speed HDMI cable, Power cord.
- Equipped with AMD's Zen 2 and RDNA 2 architectures, DirectX ray tracing delivers true-to-life lighting, shadows and accurate reflections to create dynamic, living worlds.
- Memory: 16GB GDDR6 w/320 bit-wide bus; Memory Bandwidth: 10 GB @ 560 GB/s, 6 GB @ 336 GB/s; Internal Storage: 1TB Custom NVME SSD
- Gaming Resolution: True 4K; Performance Target: Up to 120 FPS; High Dynamic Range: Up to 8K HDR; Optical Drive: 4K UHD Blu-Ray; HDMI Features: Auto Low Latency Mode, HDMI Variable Refresh Rate, AMD FreeSync.
- Bundled with HDMI_Cable
- A game that includes a 120-FPS mode on your console and selected settings.
- A television or monitor with a suitable refresh rate and an input mode that accepts the signal.
- The correct console and display settings, including the game’s performance option when one is provided.
Microsoft also lists Variable Refresh Rate (VRR) and Auto Low-Latency Mode (ALLM) support, along with HDMI 2.1 output, on its comparison and specification pages. These capabilities depend on the attached display and supported content. A basic 60Hz television will not show 120 frames per second simply because the console advertises that ceiling.
Dolby Vision and other video features
Microsoft lists Dolby Vision gaming among shared capabilities. Whether it activates depends on the display, its firmware and the game or video content. Do not treat a feature listed for the console family as proof that every television or every title supports it.
Can Xbox Series S play discs?
No. Series S is digital-only and has no optical drive. You cannot insert an Xbox game disc, UHD Blu-ray or DVD and install or play it on Series S. Your games must be obtained through digital access, such as a digital purchase or an eligible subscription.
Which Series X models play discs?
Microsoft lists Series X editions with a disc drive as well as an all-digital Series X edition. Check the exact product listing before buying: the phrase “Series X” alone does not tell you whether a particular unit has an optical drive or which storage capacity it carries.
A drive-equipped Series X can play eligible physical Xbox titles and UHD Blu-ray video discs. For a backward-compatible disc game, Microsoft says the disc must remain inserted after installation so the console can verify ownership. The all-digital Series X cannot read discs, despite sharing the Series X performance target.
Rank #3
- BEST VALUE IN GAMING — Experience next-gen speed and performance in the smallest XBOX ever. The XBOX Series S delivers powerful all-digital gameplay in a sleek, compact design.
- UP TO 120 FPS GAMEPLAY — Enjoy smooth, responsive gaming with frame rates up to 120 FPS, powered by XBOX Velocity Architecture, a custom NVMe SSD, and DirectX Raytracing for a heightened level of realism.
- 512GB CUSTOM SSD AND XBOX VELOCITY ARCHITECTURE — Reduce load times dramatically with the custom 512GB NVMe SSD and XBOX Velocity Architecture, enabling lightning-fast performance and seamless world streaming.
- QUICK RESUME — Seamlessly switch between multiple games and resume exactly where you left off. No more waiting through title screens and loading bars.
- FOUR GENERATIONS OF DIGITAL GAMES — Play thousands of digital games from XBOX Series X|S, XBOX One, XBOX 360, and Original XBOX with backward compatibility. Many titles are enhanced for better visuals and performance. Smart Delivery ensures you always get the best version for your console.
When a disc drive changes the buying decision
- You already own a physical Xbox library.
- You buy or borrow used physical games.
- You want UHD Blu-ray playback from the console.
- You want a physical disc to remain an ownership key for an eligible backward-compatible title.
If none of those apply, an all-digital Series X or a Series S may meet your needs; decide between them primarily on resolution target and storage.

How much storage do Series S and Series X have?
| Console family | Listed internal SSD options | What to check |
|---|---|---|
| Series S | 512GB or 1TB | Confirm the capacity of the specific edition; installed system software means usable space is lower than the advertised capacity. |
| Series X | 1TB or 2TB | Confirm both capacity and optical-drive status for the exact model. |
These are configuration capacities, not guarantees about free space after the operating system, reserved data and updates are installed. Game installation sizes vary widely and can change with patches, so no reliable “number of games per drive” figure exists.
Choosing 512GB, 1TB or 2TB
- Series S 512GB: Suitable when your digital library is modest and you are comfortable managing installs. Large modern games can consume a substantial share of the available space.
- Series S 1TB: The practical Series S choice when you want digital-only play but fewer uninstall and reinstall cycles.
- Series X 1TB: Combines the Series X performance target with the baseline listed X capacity; verify whether the edition includes a drive.
- Series X 2TB: Best for a large installed library, provided that capacity is offered in your region and on the edition you intend to buy.
Expansion cards versus USB hard drives
Both consoles support the Xbox Series X|S Storage Expansion Card. Microsoft describes that dedicated card as adding storage at the console’s internal SSD performance. It is the appropriate option when you want to run Series X|S-optimized games directly from expanded storage at the intended speed.
Microsoft also lists USB 3.1 external hard-drive support. A generic USB drive is useful for storing games and moving them, but it should not be treated as equivalent to the dedicated expansion card’s internal-SSD performance. Check each game’s requirements before assuming it can run directly from a USB drive.
Expansion-card pricing and availability vary by market and retailer. Include that optional cost in your ownership calculation rather than assuming every capacity option has the same value.

Shared game features on both consoles
Quick Resume
Quick Resume lets supported games remain in a suspended state so you can switch among multiple titles more quickly. Microsoft presents it as a Series X|S family feature. The number of games that can remain available is not fixed: memory use, game behavior, updates and system activity affect what stays suspended. Do not buy one model expecting a guaranteed count of simultaneously resumable games.
Smart Delivery
Eligible Smart Delivery purchases provide the best version for the Xbox console on which you play. It is a shared ecosystem feature, not a guarantee that every game has a special Series X|S upgrade. Check a game’s own listing for its supported versions, saves and entitlements.
Backward compatibility
Xbox says Series S is compatible with thousands of games spanning four generations, but its disc-free design means disc-based games are not supported. Series X supports eligible backward-compatible disc titles when you choose a drive-equipped edition; the disc must remain inserted to play an installed disc version.
Digital backward-compatible games and saves depend on the title and account entitlements. Confirm a specific game in the current Xbox compatibility catalog rather than assuming every Xbox, Xbox 360 or Xbox One release works.

Xbox One accessories
Microsoft says Series X|S works with most Xbox One controllers and gaming accessories. “Most” is important: compatibility is not universal for every accessory. Check the accessory maker’s current support information if a specialized wheel, headset, adapter or controller is central to your setup.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Entertainment and connectivity
Microsoft lists HDMI 2.1 output, VRR, ALLM and Dolby Vision gaming for the console family, subject to display and content support. It also lists streaming applications and 4K Ultra HD video capabilities. Streaming subscriptions are separate services; buying a console does not automatically include a subscription to every listed application.
For a television upgrade, match the display to the mode you actually intend to use: 4K resolution for Series X’s target, a high refresh rate for supported 120-FPS games, and compatible HDMI and VRR features when those matter. A premium display cannot make a game render at a mode the developer did not provide.
Which Xbox should you buy?
Choose Series X with a disc drive when…
- You want the strongest official 4K target and have a 4K display.
- You own physical Xbox games or buy used discs.
- You need UHD Blu-ray playback.
- You want the larger 2TB option when that edition is available.
Choose an all-digital Series X when…
- You want Series X’s native-4K target and storage choices.
- Your library is entirely digital.
- You have no need for physical games or disc-based backward compatibility.
- You have confirmed that the local all-digital edition has the capacity and features you want.
Choose Series S 1TB when…
- You want a digital-only console designed around 1440p.
- You prefer more internal space than the 512GB configuration.
- Your display and favorite games do not require a native-4K target.
Choose Series S 512GB when…
- You are comfortable maintaining a smaller installed library.
- You do not need discs, UHD Blu-ray or native 4K rendering.
- The listed capacity is sufficient after allowing for system software and updates.
When neither console should be chosen on specifications alone
If one game determines your purchase, verify its current resolution and frame-rate modes on both consoles. Developer updates can change performance options, and Microsoft’s “up to 120 FPS” language is conditional. For that buyer, title-specific support is more useful than a generic specification comparison.

Microsoft states that prices and availability vary by market and retailer, so a single current price would not be reliable for every reader. Compare the exact edition rather than a family name: drive-equipped and all-digital Series X models can differ, as can 512GB and 1TB Series S units.
Calculate total ownership cost using these items:
- The exact console edition and its included storage.
- Optional Series X|S Storage Expansion Card if your library will exceed internal space.
- Games, whether purchased digitally or physically.
- Any separately purchased subscription, such as Game Pass, after checking the current tier, price and regional terms.
- A display upgrade only if your existing television cannot show the modes you value.
Do not assume Series S is automatically cheaper over several years: a lower-capacity model may lead to an expansion-card purchase, and an all-digital library removes the option of buying discounted used discs. Conversely, a drive-equipped Series X costs more only if its additional capabilities matter to you; digital-only buyers should compare it with the all-digital edition available in their market.
Setup checklist before you buy
- Identify your library: list physical discs, digital purchases and any backward-compatible titles you expect to use.
- Check the display: note its resolution, refresh rate, HDMI input capability and VRR support.
- Check the game: verify the current Series S/Series X modes for your most-played titles.
- Choose capacity: compare 512GB, 1TB and 2TB listings, allowing for system-reserved space.
- Confirm the edition: make sure the product page clearly states optical-drive presence or all-digital status.
- Budget expansion: include a dedicated expansion card if you expect a large Series X|S game library.
- Verify accessories: confirm that your existing Xbox One accessories are among the supported devices.
Bottom-line decision
Series X is the better fit for native-4K priorities, physical media and larger storage configurations. Series S is the better fit for a digital-only buyer who accepts a 1440p design target and chooses between 512GB and 1TB. Both deliver the same core Xbox features and advertise up to 120 FPS, but neither specification guarantees a particular game’s resolution or frame rate. Match the console to your display, discs, favorite games and storage needs, then verify the exact regional edition before ordering.
