Can An APU Replace Your Graphics Card?

Yes, a high-quality APU can replace your graphics card, but the performance of high-resolution games and graphics may not be same as GPU.

An APU, or accelerated processing unit, is a CPU that has integrated graphics processing capabilities. This means that it can handle both general computing tasks and graphics-intensive tasks such as gaming without the need for a separate GPU.

If you’re a PC gamer, you’re probably always on the lookout for ways to improve your gaming rig. One of the most important components for any serious gamer is a graphics card. But what if you could ditch your graphics card and use an APU instead? Let’s look at whether an APU can really replace your graphics card.

Key Differences Between APU VS CPU VS GPU

APU, CPU, and GPU are three distinct components used in computing systems, each with its specific function. The key differences between these terms are:

APU (Accelerated Processing Unit): An APU is a type of processor that combines a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit) into a single chip. It is designed to perform both general computing tasks and graphics processing tasks. APUs are commonly used in low-power devices such as laptops, tablets, and smartphones.

CPU (Central Processing Unit): A CPU is the brain of a computer that performs all the calculations and logical operations required to run programs and applications. It is responsible for executing instructions and controlling the other components of the computer.

CPUs are usually multi-core and can handle multiple tasks simultaneously.

GPU (Graphics Processing Unit): A GPU is a specialized processor designed to handle graphics-related tasks such as rendering images, videos, and animations. It is optimized for parallel processing and can perform complex calculations required for 3D graphics and video editing. GPUs are commonly used in gaming systems, workstations, and high-performance computing applications.

In summary, an APU combines the functions of a CPU and GPU in a single chip, while a CPU is responsible for general computing tasks, and a GPU is specialized for graphics-related tasks.

What Are Advantages and Disadvantages of Using CPU Over a GPU?

Here are some advantages and disadvantages.

Advantages of Using CPU Over a GPU

There are several advantages to using an APU over a GPU.

  • Firstly, APUs are often more affordable than GPUs, making them a great option for budget-conscious gamers.
  • Secondly, they tend to be more power-efficient, meaning that they won’t put as much strain on your power supply or generate as much heat.
  • Finally, they’re often easier to install and set up than GPUs, as they don’t require any additional drivers or software.

Disadvantages of Using APU Instead Of a GPU

Of course, there are also some disadvantages to using an APU instead of a GPU. For one thing, dedicated GPUs tend to offer better performance than APUs – although this gap is narrowing as technology improves.

Additionally, GPUs usually come with their own dedicated memory (VRAM), whereas most APUs share system RAM with the CPU. This can lead to slower performance and lower graphics quality in some cases.


So, should you use an APU or a GPU? Ultimately, the decision comes down to personal preference and budget. If you want the best possible gaming performance, then you’ll probably want to opt for a dedicated GPU. However, if you’re looking for a more affordable option that will still allow you to enjoy most games without any problems, then an APU could be the way to go.

How to get the most out of your APU

There are two main ways to get the most out of your APU.

  • The second way to get the most out of your APU is to use it as your main processor and pair it with a dedicated graphics card. This setup will give you the best performance in games that rely heavily on graphics, such as first-person shooters and massively multiplayer online games.

No matter which way you choose to use your APU, you’ll be getting better performance than if you were using a CPU and separate GPU.

Things to Keep in Mind For Using APU

If you’re thinking of using an APU in your next build, here are a few things to keep in mind:

  1. If you’re looking to play the latest AAA titles at 4K resolutions with all the settings maxed out, an APU is probably not going to work smoothly. However, if you’re willing to lower some of the detail levels or play at lower resolutions, an APU can still provide a great gaming experience.
  2. Consider upgrading your CPU parallelly. APU performance is highly dependent on the CPU with which it is paired. When building a system around an APU, we recommend opting for a high-end CPU if you can afford it. This will ensure that your system can utilise the graphics processor to its fullest potential.
  3. Make sure your motherboard has appropriate BIOS support. This is usually indicated by having an “IGP Enable” or “IGPU Multi-Monitor” option in the BIOS menu. If you don’t see these options, it’s likely that your motherboard doesn’t support using an APU without a discrete graphics card installed.

  4. Use DDR4 memory for best results. While DDR3 memory will work with most APUs, you will get better performance from DDR4 memory modules operating at 2133MHz or higher speeds. If possible, we recommend opting for faster memory modules when building a system around an APU. This will help improve both CPU and GPU performance.

FAQs about APUs

What is an APU?

An accelerated processing unit (APU) is a microprocessor that integrates a graphics processing unit (GPU) on the same die. In other words, it’s a CPU with integrated graphics, and it’s designed to improve overall system performance.

What are the benefits of an APU?

An APU can offer a number of benefits over a traditional CPU or GPU, including improved overall system performance, reduced heat and power consumption, and increased efficiency.

Can an APU replace my graphics card?

In some cases, an APU can replace your need for a separate graphics card. For example, if you’re using your PC for general computing tasks and light gaming, an APU may be all you need. However, if you’re looking to play the latest AAA games at high settings, you’ll likely need a separate graphics card.

What are the downsides of an APU?

One potential downside of an APU is that they can be more expensive than a traditional CPU or GPU. Additionally, because they integrate both CPU and GPU functionality on one die, they can be more difficult to upgrade in the future.
