Do APU And GPU Work Together? Answered & Explained

Do APU And GPU Work Together? |

Want to know do APU and GPU work together? APU is (Accelerated Processing Unit); it is a chip located on your motherboard’s circuit board. AMD introduced the first APU in 2011 and the second generation APU in 2012. The APU offers integrated graphics, high-definition video, and high-performance processing and frame rates. 

GPU stands for (Graphics Processing Unit); it is a chip that processes graphical data such as textures, video, and 3D rendering. It allows you to game at high resolutions; GPU is not necessary for general computing tasks such as browsing the web, using office applications or watching videos.

Do APU And GPU Work Together?

Both APU and GPU are capable of working together. They accelerate the graphic performance of your computer when used together. However, there are a few things to consider before combining the APU with GPU. Your APU must support the GPU, and the motherboard must have the compatibility to support both. 

APUs are also called microprocessors because they support general processing besides providing integrated graphics. As AMD introduced the APU, they called them Fusion. They are 64-Bit Microprocessors that support the CPU in general functioning resulting in high computer performance. 

How Do I Switch From APU to GPU?

To switch from APU to GPU, you have to disable the APU. You can disable it through AMD catalyst or BIOS settings. You can also disable the APU from the Device Manager. First, open the device manager, then select the “Display adapters” option. Now right-click the integrated APU and select “Disable”.

Make sure to plugin and installed the graphics card before disabling the APU. Otherwise, you may face display issues after disabling it.

In the case of an AMD processor with APU having integrated graphics, you don’t have to switch to the external GPU. If you are a gamer and want more graphics, then it’s the best option to use both APU and GPU with a higher amount of RAM.

How To Connect APU with GPU?

APU and GPU require a precise selection of motherboards to run both chips side by side. Such integrated motherboards are called APU on-board motherboards. Before connecting, read the motherboard manual to see if it supports the combination. If you are good to go, then here’s how you can do it:

Connecting GPU with Motherboard:

  • First of all, connect the dedicated GPU with your motherboard. You just have to slide down the Graphics card into your motherboard graphic card socket.

Configuration and Settings:

  • Connect your video cables and turn on your computer. 
  • Now install your Graphic card drivers from the professional website. 
  • After installing the Graphic card, go to the AMD Catalyst settings and open the “Performance” bar.
  • Now click on the “AMD CrossFire” option; if it’s disabled, then enable it. Just after enabling the restart of your PC, your APU will be integrated with your GPU, and both will start working.

If you are still unable to find the Crossfire or it doesn’t appear on the side menu, here’ is the second method that you can follow.

Configure Through BIOS

  • Restart your PC and open the BIOS settings (Del or F2) with the BIOS key. 
  • Once you are in the BIOS, search for “Advanced Options.”

  • Open the Advanced options and then navigate to “NBConfiguration.” You can find this option in all motherboards that support APU.

  • Now “Enable” the IGFX Multi-monitor option if it’s disabled. The IGPU is not enabled, and you have to enable it.

  • The next option to configure is “Integrated Graphics.” Open the file and select “Force from the options. It will enable your APU forcefully. It’s safe to do that.

  • It’s time to set the share graphic memory to your APU. To do that, select the “UMA frame buffer size” option. Now select the required memory according to your RAMs from the list i.e. 1GB or 2GB.

  • After configuring the APU, exit the setup by using the “Save & Exit” option. 
  • Now open the AMD Catalyst again and go to the Gaming tab. Here you will find the “Enabled” ADM Dual Graphic option. Your APU is ready to roll with GPU.

What’s The Difference Between APU and GPU?

APUs are mostly used in terms of a microprocessor or general-purpose processor. However, these APUs also support the GPU to enhance integrated graphics. So, both have similar functions, but which one is more powerful? Here are some key differences between APU and GPU:

Cheaper to build a PC as compared to GPU. Expensive to build a PC with GPU.
Supports the GPU in rendering.  Renders the 3D images.
Also known as Fusion or Microprocessors.  Known as Graphics card. 
It may consist of both graphic and processing units. It only consists of a Graphics unit.
Fewer transistors are present, so they are less efficient.  More transistors than the APU. 
More power-efficient. Less power-efficient.
Gaming gives more FPS than integrated Graphics. Gaming gives more FPS than APU and integrated Graphics. 
Less graphic capability. High graphic capability.
Reduces the available memory on PC. Don’t affect the memory of the PC. 

This means that an APU can offer better performance and efficiency than a CPU, but the GPU performs more efficiently than APU. As APU has both integrated graphics and processors at the same time. APU has the ability to work without GPU as it has both graphic and microprocessors. 

Can You Run Dual GPU with a Single APU?

Yes, you can use dual GPU with a single APU. However, a setup with two graphics cards will require more memory to divide the processing. It will also require extra RAM to run dual GPU with a single APU. 

You have to connect both the GPUs and Crossfire them. Now you have to enable the APU as we have described above. This will enable all three components. The main things you need to consider when using a dual GPU setup are the power requirements and cooling. 

Regarding power requirements, it is important to have a power supply that can handle the increased load. Typically, a dual GPU setup will require more power than a single GPU. You may also consider adding a cooling solution for your GPUs if they get too hot.

Is APU Better Than GPU For Gaming?

No, APU is not better than the GPU in any case. GPU provides power to all graphics and textures. While APU just supports the CPU or GPU in processes. It doesn’t directly enhance the performance. If you are looking for a better value option for money, then GPU is better than APU. 

You can consider APU if you are looking for budget gaming. You can only get the best performance of APU by combining it with GPU.o The amount of Hertz increases as both APU ad GPU are Crossfire. Even the AMD has launched their APU chipsets that directly work with GPU without external support.

As APU affects your computer system’s available memory (RAM), it may decrease the gaming performance if you have a limited amount of available RAM. So, if you have a low-end gaming computer with limited RAM, the GPU would be a better option.
