Using MUX in Different Brands of Computers: A Deep Dive

Modified on Tue, 24 Oct 2023 at 09:37 AM

The idea of MUX (Multiplexer) is gaining popularity in the huge world of high-performance laptops, especially among professionals and gamers. However, what is MUX? Why should you worry about how different brands apply it? This article examines it in more detail.

1. What is MUX?

In the context of laptops, a multiplexer (MUX) is a piece of hardware that enables users to switch between the dedicated GPU (such as NVIDIA or AMD) and the integrated GPU (usually Intel). Users can optimize for performance or battery life by choosing which GPU handles the display output.

2. Why MUX Matters

  • Performance: Directly connecting the display to a dedicated GPU (dGPU) bypasses the integrated GPU (iGPU), potentially reducing input lag and boosting gaming performance.

  • Battery Life: For non-intensive tasks, routing display through the iGPU can save power, extending battery life.

  • Flexibility: Having the option to switch provides users the best of both worlds, allowing for a tailored computing experience based on the task at hand.

3. Implementation Across Brands

While the underlying concept remains consistent, different brands have their unique twists and software solutions to control MUX.

a. ASUS: Certain ASUS ROG (Republic of Gamers) laptops are equipped with the GPU switch. The Armoury Crate software often provides control over MUX settings, enabling users to decide which GPU to use.

b. MSI: MSI laptops with MUX often come with the Dragon Center software, allowing users to manage GPU selections, monitor system health, and optimize performance settings.

c. XOTIC PC: Being a boutique builder, XOTIC PC provides extensive customization, ensuring optimal MUX configurations based on the chosen hardware. This gives users unparalleled flexibility in controlling their device's GPU output.

4. Things to Consider

  • Reboot Requirements: Switching between GPUs might require a system reboot in some brands or models.

  • External Monitors: Connecting an external monitor directly to the dGPU can provide a performance boost, as it bypasses the MUX entirely.

  • Driver Compatibility: Ensure drivers are up-to-date to prevent potential conflicts when switching between GPUs.


A flexible option to strike a balance between pure performance and energy conservation is provided by MUX. While how it is implemented may vary between brands, its basic objective—offering users a choice—remains the same. Whether you're gaming, creating, or just browsing, XOTIC PC aims to provide an unmatched computing experience by understanding the complexities of this technology.
