Gaming laptops are way more advanced than they used to be a few years ago. One of the many new features that you can see on some of the best gaming laptops is the MUX switch, a feature that can be used to boost graphics performance. But how does it really work, and should you spend extra money just for this feature? Here is everything you need to know.
Most gaming laptops have a pair of GPUs, an integrated GPU , and a discrete GPU . An iGPU is a part of the processor, meaning that Intel and AMD both offer their own integrated graphics solution. On the other hand, a discrete GPU is the beefier graphics chip on your laptop, like the Nvidia RTX 3070 or AMD Radeon RX 6700s, that is required to drive high-end games.
A laptop that has Optimus will automatically conserve the battery by switching it to integrated graphics when you do not require a lot of graphics power. As soon as you open a GPU-intensive workload, say a game, it recognizes the requirement and switches back to the dGPU. It sounds convenient and is even claimed to offer an increased performance of up to 30%, but there is a flaw.
If you don’t have a MUX switch on your laptop, you can still boost gaming performance by overclocking your GPU or connecting an external gaming monitor to your laptop. You do need to ensure that the display output is connected directly to the discrete graphics instead of the Intel or AMD integrated GPU, though.
