Can Integrated and Dedicated GPUs Work Together?

Have you ever wondered if you can harness the power of both your laptop’s built-in graphics and a fancy dedicated graphics card? Maybe you’re looking to squeeze more performance out of your existing setup or are curious about making the most of your hardware. In this blog post, we’ll tackle the question: “Does integrated GPU work with dedicated GPU?” We’ll explore how they can (or cannot) collaborate and what benefits you might see.

Integrated vs. Dedicated GPUs

Before we dive into whether they work in tandem, let’s clarify what these two types of GPUs are:

a). Integrated GPU

This graphics processor is built directly into your computer’s CPU (processor). It’s designed for basic tasks like browsing the web, watching videos, and light gaming. They prioritize power efficiency and affordability.

b). Dedicated GPU

This is a separate graphics card that you install into your computer, designed specifically to handle demanding graphics tasks like high-end gaming, video editing, and 3D rendering. They offer way more power and performance compared to integrated GPUs.

Can Integrated and Dedicated GPUs Really Work Together?

The short answer is: It depends. Here’s the breakdown:

  • Not for Performance Boost: Unfortunately, you can’t simply combine the power of your integrated and dedicated GPU to create a super-graphics powerhouse. They typically can’t work together to directly improve gaming performance or 3D rendering speeds.
  • Possible Collaboration (sometimes): There are certain technologies and scenarios where your integrated GPU might work with your dedicated GPU. Here are a few instances:
    • Multi-Monitor Support: Some laptops enable using the integrated GPU to handle basic display output on secondary monitors while the dedicated GPU takes care of the demanding work on your main gaming display.
    • Power Saving: Some technologies like Nvidia Optimus allow your system to intelligently switch between the dedicated GPU (for high-power tasks) and the integrated GPU (for everyday work) to conserve battery life on laptops.
    • Specific Applications: Certain software applications might be able to offload specific graphics-related tasks to the integrated GPU. However, this is usually on a case-by-case basis.

Why You Usually Don’t Want Them to Combine for Gaming

It’s important to understand that even in scenarios where it seems your integrated GPU and dedicated GPU are “working together,” they’re not directly combining their processing power for rendering your games. Trying to force this kind of collaboration can often lead to worse performance because of the added overhead of communication and data transfer between the two GPUs.

Should You Upgrade to a Dedicated GPU?

If you’re serious about gaming, or work with graphics-intensive applications, having a dedicated GPU is highly recommended. Here’s why:

  • Significant Performance Boost: Dedicated GPUs offer a massive increase in graphics processing, letting you enjoy higher frame rates, smoother gameplay, increased resolutions, and more advanced visual effects.
  • Handle Demanding Tasks: A dedicated GPU is essential for tasks like modern AAA game titles, video editing, 3D modeling, and other graphically intensive applications.


While the idea of combining your integrated GPU and dedicated GPU for ultimate performance might be tempting, the reality is that they generally function independently. However, there are some benefits to having both in terms of display output and power management. If you desire the best possible graphics performance, a dedicated GPU is the way to go.
