Why My laptop has two graphics cards?

Gaming, 3D graphics, and video quality are all improving, raising the need for a better GPU. That’s the reason laptops nowadays come up with two Graphics cards, Integrated and Dedicated.

It’s mainly to make a laptop powerful. But the confusing part is that you can utilize one graphic card at a time despite having two. Why?

The reason is simple

Generally speaking, higher Graphical performance isn’t always required. Regardless of how powerful the laptop is, we frequently use it for simple tasks such as browsing the web, streaming Netflix, and doing basic office work, using the zoom app for video calls. It is here that switching the card comes in handy, enabling you to switch between high performance and balance modes of your laptop.

The idea of Two graphic cards in one laptop

In powerful workstations or gaming laptops, manufacturers often include two graphics cards. Integrated and Dedicated GPU. 

Dedicated GPUs are always more powerful than Integrated GPUs (iGPUs). Since you will not want your laptop’s battery to run out quickly and make your laptop overheat. So with the option to switch, you can manage battery life.

Thus, managing battery life is the main idea behind it. In other words, you can extend the battery performance by switching to the integrated GPU. When battery timing is not important, such as when playing games or working on a GPU-intensive task, switch to the dedicated GPU.

As an example, the GPU from Intel helps the battery last slightly longer. Switching to discrete graphics (Nvidia, Geforce, Radeon) will drain the battery quicker yet provide better graphical performance.

  • Integrated GPUs (from Intel or AMD, depending on your motherboard) are low-powered GPUs for basic tasks, watching videos, running low-end programs, and playing video games. See integrated GPUs.
  • A dedicated graphics card is usually provided by Nvidia, Radeon, or another popular graphic card manufacturer. These GPUs are more powerful so that they can be used to play high-end games such as GTA V, PUBG PC, and COD, or run GPU-intensive programs such as After Effects.

My laptop also has two graphics cards. 

One is built-in (Intel’s 620 UHD) and the second one is Radeon 530. 

When the apps don’t demand high GPU power, such as when I write articles, send emails, or watch Netflix, I switch to Intel’s UHD 620. The benefit I get is, my laptop does not overheat, and the battery also lasts longer.

In contrast, I get the best performance from my Radeon 530 graphics card when I play games. For this reason, I mostly use it when I play video games. Overheating, and short battery life is common when my laptop is producing too much power.
