Xiaomi’s Xring O3 chip could make future Android devices much better at running Windows games
Xiaomi’s custom Xring O3 processor is shaping up to be more than just another high-end mobile chip. New graphics capability data for the Xiaomi 18 Fold indicates that the chipset supports the full BCn block-compressed texture format family, from BC1 through BC7. That may sound highly technical, but it could have a real impact on gaming, emulation, and Windows app compatibility on Xiaomi devices.
The same Xring O3 chip is also used in the Xiaomi Pad 9 Pro Max, which means this feature is likely not limited to the foldable phone. Xiaomi’s premium tablet lineup could also benefit from the same advanced graphics compatibility, making it potentially more useful for users who want a tablet capable of handling PC-style workloads and game translation layers.
BCn texture support is important because many PC and console games rely on these compressed texture formats. Android, by contrast, typically focuses on formats such as ASTC and ETC2. Since BCn is not a required feature for Android devices, many mobile chips do not expose full support for it, even when their GPUs are based on similar Arm Mali graphics technology.
That is what makes Xiaomi’s implementation stand out. Some mobile processors using Mali-based GPUs have not offered native BCn support, which can create problems when running desktop games or using compatibility tools designed to bring Windows software to ARM-based devices. Xiaomi appears to have enabled this capability in the Xring O3, giving its chip a feature that has traditionally been rare in the Android space.
The report shows that the Xiaomi 18 Fold supports sampling, blitting, and transfer operations across BC1, BC2, BC3, BC4, BC5, BC6, and BC7 formats. In simple terms, the GPU can properly handle a wide range of BC-compressed textures directly, rather than forcing the system to work around the issue through less efficient methods.
This matters most for compatibility, not necessarily day-to-day Android performance. Regular mobile apps and Android games are unlikely to see a major change from BCn support because most are already optimized for Android’s standard texture formats. However, PC games, console-style engines, emulators, Windows-on-ARM tools, and translation layers can benefit significantly.
Without native BCn decoding, a device may need to decompress textures through software. That can increase memory usage, reduce performance, and drain battery faster. Native hardware support helps avoid those penalties, making games and desktop applications run more smoothly and efficiently.
For Xiaomi, this could be an important step toward making its devices more versatile. The Xring O3 is not just competing as a smartphone chip; it may also be designed with broader computing in mind. If Xiaomi continues in this direction, future phones, foldables, and tablets could become stronger options for users interested in mobile productivity, emulation, and PC gaming on portable devices.
The Xiaomi 18 Fold and Xiaomi Pad 9 Pro Max may therefore represent more than standard flagship hardware upgrades. With full BCn texture format support, the Xring O3 suggests that Xiaomi is paying attention to the growing demand for Android devices that can handle more desktop-like software experiences.
As Windows-on-ARM development, game compatibility layers, and high-performance Android tablets continue to evolve, features like native BCn decoding could become increasingly important. Xiaomi’s decision to include it in the Xring O3 may give the company an edge as mobile devices move closer to becoming true portable gaming and productivity machines.
