Xbox Series X vs Series S GPU Performance Differences

This article explores the significant GPU performance disparities between Microsoft’s Xbox Series X and Xbox Series S consoles. We will examine technical specifications, resolution targets, and real-world gaming implications to help you understand which machine best fits your gaming needs.

The most prominent difference lies in the raw computational power measured in teraflops. The Xbox Series X boasts a custom AMD RDNA 2 GPU capable of 12 teraflops of processing power. In contrast, the Xbox Series S is equipped with a locked-down version of the same architecture, delivering approximately 4 teraflops. This threefold difference means the Series X is designed to handle much more complex graphical calculations, allowing for higher fidelity textures, more advanced lighting effects, and denser object populations within game worlds.

Resolution output is the most visible consequence of this GPU gap. The Series X targets native 4K resolution at 60 frames per second, with support for up to 120fps in compatible titles. The Series S, however, typically targets 1440p resolution at 60fps, though it can upscale to 4K for media consumption. In demanding titles, the Series S may drop to 1080p to maintain stable frame rates. Gamers with 4K televisions will notice a sharper image on the Series X, while the Series S remains an excellent choice for 1080p or 1440p monitors.

Memory bandwidth further distinguishes the two systems. The Series X utilizes 16GB of GDDR6 RAM with a bandwidth of 560 GB/s, whereas the Series S contains 10GB of GDDR6 RAM with 224 GB/s bandwidth. This limitation affects how quickly data can be moved between the GPU and memory, impacting load times and the complexity of assets that can be streamed into the game engine simultaneously. While both consoles utilize high-speed NVMe SSDs for storage, the GPU memory constraint on the Series S can limit texture quality in cross-generation titles.

Ultimately, the choice depends on your display hardware and performance expectations. The Xbox Series X is the definitive option for players seeking maximum graphical fidelity and native 4K gaming. The Xbox Series S offers a cost-effective entry point into next-gen gaming, sacrificing some resolution and graphical settings for a lower price point and a compact, all-digital form factor. Both consoles share the same CPU architecture, ensuring similar logic and physics performance, but the GPU remains the deciding factor for visual quality.
