The Xbox Series X delivers native 4K resolution, 120 FPS targets, and instant SSD loading, fully outclassing the 1080p-focused, HDD-based Xbox One S.
Gamers looking to upgrade often ask if the jump from the older Xbox One S to the flagship Series X is worth the cost. The difference goes beyond just graphics; it fundamentally changes how games feel, load, and perform.
This breakdown compares specific hardware limits, load times, and game support to help you decide if it is time to trade in the old console.
Graphic Power And Resolution Specs
The most visible gap between these two machines is raw graphical output. The Xbox One S was designed for 1080p displays, while the Series X targets 4K screens.
GPU Performance
The Xbox Series X pushes 12 teraflops of processing power. The One S pushes roughly 1.4 teraflops. This massive gap allows the Series X to render complex lighting, shadows, and textures that the One S simply cannot compute.
Games on the One S often look blurry or jagged on modern TVs because the system uses upscaling to fit the screen. The Series X outputs a native 4K signal, keeping the image crisp.
Frame Rates
Fluid motion matters for competitive gaming and immersion. The capabilities differ sharply:
- Xbox Series X — Targets 60 FPS as a standard, with support for up to 120 FPS in compatible titles like Call of Duty or Halo Infinite.
- Xbox One S — Struggles to maintain 30 FPS in modern titles and caps at 60 FPS for older, less demanding games.
If you play shooters or racing games, the input lag reduction on the Series X makes gameplay feel tighter and more responsive.
Storage Speed And Load Times
The storage type is arguably the most practical upgrade. The Xbox One S uses an old mechanical Hard Disk Drive (HDD). The Series X uses a custom NVMe Solid State Drive (SSD).
Load time comparison:
- Open world games — A game like GTA V might take over a minute to load on One S. It loads in seconds on Series X.
- Fast travel — Teleporting across a map is near-instant on the new console, removing the wait screens common on the One S.
Quick Resume Feature
Only the Series X (and Series S) supports Quick Resume. This feature lets you suspend multiple games at once and switch between them instantly. You can jump from a race in Forza to a match in FIFA without booting either game from scratch. The Xbox One S requires you to close one game fully before opening another.
Comparing Xbox Series X And One S Disc Drives
Both consoles feature physical disc slots, which is great for collectors or those with large libraries of used discs. However, the capabilities of these drives differ.
4K Blu-ray Playback:
- Xbox Series X — Plays 4K UHD Blu-ray discs natively.
- Xbox One S — Also plays 4K UHD Blu-ray discs.
Surprisingly, the One S is still a competent media player. If your main goal is watching movies on discs rather than gaming, the One S remains a budget-friendly option.
Game Library And Compatibility
Microsoft handles game libraries differently than competitors. Your digital purchases generally move with you, but new games have restrictions.
Backward Compatibility
The Series X plays thousands of Xbox One, Xbox 360, and original Xbox games. In many cases, it enhances them. Older titles often run with Auto HDR and more stable frame rates on the newer hardware.
You can check the official Xbox Backward Compatibility library to see if your favorite older discs will work. Most do.
Next-Gen Exclusives
Newer titles like Starfield or the latest Forza Motorsport are built specifically for the Series X/S hardware. The Xbox One S cannot run these games natively. To play them on a One S, you must use Xbox Cloud Gaming, which requires a strong internet connection and a Game Pass Ultimate subscription.
Smart Delivery
Microsoft uses a system called Smart Delivery. If you buy a game like Cyberpunk 2077, the console automatically downloads the best version for your hardware. On Series X, you get the version with ray tracing and high textures. On One S, you get the lower-resolution version.
Physical Size And Connectivity
These consoles look nothing alike. The visual design reflects their cooling needs.
- Xbox Series X — A dense, black tower (15.1cm x 15.1cm x 30.1cm). It is heavy and requires open space for the large fan to exhaust heat.
- Xbox One S — A slim, white rectangle. It fits easily into standard media cabinets and is significantly lighter.
Port differences:
The Series X uses HDMI 2.1, which allows for higher data transfer needed for 120Hz gaming on modern TVs. The One S uses the older HDMI 2.0 standard. The Series X also removes the optical audio port and the dedicated Kinect port found on older Xbox One models.
Price And Value Assessment
Cost is the main barrier. The Xbox Series X retails for around $499. The Xbox One S has been discontinued, but used units often sell for $150 to $200.
Who Should Keep The One S?
Stick with the One S if you only play light indie games, use the console primarily for streaming Netflix or 4K Blu-rays, or have a tight budget. It still functions well as a media hub.
Who Needs The Series X?
Upgrade to the Series X if you own a 4K TV and want to see what it can actually do. The reduction in load times alone changes the rhythm of gaming. If you plan to play major releases for the next five years, the One S is no longer viable hardware.
Verdict On The Upgrade
The Xbox Series X is not just a small step up; it is a complete overhaul of performance. While the Xbox One S holds up as a media player, it fails to run modern games at acceptable standards. The SSD speed, 4K capability, and stable frame rates make the Series X the clear winner for anyone serious about gaming.
