Lenovo legion 5’s hidden ace: uncover the secret of the mux switch

The Lenovo Legion 5 is a highly sought-after gaming laptop that boasts impressive specifications and features. However, one question that often arises among potential buyers is whether it incorporates a MUX switch. This article delves into the world of MUX switches and explores their significance in gaming laptops, particularly in the context of the Lenovo Legion 5.

What is a MUX Switch?

A MUX (multiplexer) switch is a hardware component that allows a laptop to switch between using the integrated GPU (iGPU) and the dedicated GPU (dGPU). In most laptops, the iGPU is used for basic tasks and power saving, while the dGPU is employed for demanding tasks like gaming.

Benefits of a MUX Switch

The presence of a MUX switch offers several advantages:

• Improved Performance: By allowing the dGPU to directly connect to the display, a MUX switch bypasses the iGPU, resulting in significantly improved performance in games.
• Reduced Bottlenecks: Without a MUX switch, the iGPU can become a bottleneck for the dGPU, limiting its full potential.
• Lower Latency: A MUX switch reduces input latency by eliminating the need for the signal to pass through the iGPU before reaching the display.

Does the Lenovo Legion 5 Have a MUX Switch?

The answer is yes. The Lenovo Legion 5 series features a MUX switch on select models. Specifically, the Legion 5 Pro and Legion 5i Pro models with NVIDIA GeForce RTX 3060, 3070, and 3080 GPUs come equipped with a MUX switch.

How to Enable the MUX Switch on the Lenovo Legion 5

To enable the MUX switch on your Lenovo Legion 5, follow these steps:

1. Ensure that your laptop is powered on and connected to an external display.
2. Right-click on the NVIDIA Control Panel icon in the taskbar and select “NVIDIA Control Panel.”
3. Navigate to “3D Settings” and click on the “Manage 3D Settings” tab.
4. Under the “Global Settings” section, scroll down to “Preferred Graphics Processor” and select “High-performance NVIDIA processor.”
5. Click “Apply” to save your changes.

Benchmarks and Performance Gains

Independent benchmarks have shown that enabling the MUX switch on the Lenovo Legion 5 can result in significant performance improvements. For example, in the popular game “Cyberpunk 2077,” enabling the MUX switch increased frame rates by an average of 15%.

Other Considerations

While a MUX switch offers substantial benefits, there are a few considerations to keep in mind:

• Battery Life: Using the dGPU exclusively can impact battery life compared to relying solely on the iGPU.
• Heat and Noise: Utilizing the dGPU for extended periods can generate more heat and noise than the iGPU.
• Not All Models: The MUX switch is not available on all Lenovo Legion 5 models, so it’s essential to check the specifications before purchasing.

Takeaways: Empowering Your Gaming Experience

The inclusion of a MUX switch in select Lenovo Legion 5 models is a game-changer for gamers. By allowing the dGPU to directly connect to the display, the MUX switch unlocks the full potential of the laptop’s graphics capabilities, providing smoother gameplay, reduced latency, and improved performance.
