Do I Need A CPU With Integrated Graphics If I Have A GPU?

Your computer’s CPU controls all the processes needed to run your system properly. For example, when a GPU is installed, the CPU coordinates all the processes between your processor, memory, and other components.

All modern CPUs have integrated graphics, and all GPUs have a CPU to enhance the processing. Here, we will discuss whether you still need a CPU with integrated graphics when you have a GPU installed.

Do I Need A CPU With Integrated Graphics If I Have A GPU?

You don’t need a CPU with integrated graphics if your PC has a GPU. It is because your PC will use the graphics card to display and render, not the CPU’s graphics. No doubt you can crossfire two or more GPUs, but you can’t crossfire CPU-integrated graphics with the GPU. 

Crossfire between two GPUs is a great way to boost gaming performance, but it is not required if you already have a high-end GPU installed. Mostly, this technique is used for budget gamers who can’t afford a high-end GPU but still want to enjoy gaming with decent performance.

On the other hand, if you don’t have a GPU on your PC, you will need integrated graphics because the CPU won’t be able to render and perform graphic-demanding tasks. Moreover, some CPUs don’t have integrated graphics, and you will need a dedicated GPU.

Integrated or external graphics overall help in the performance of your PC. A GPU will be responsible for graphic rendering; if you don’t, a CPU with integrated graphics will do the job for you.

Do All Processors Have Integrated Graphics?

All processors don’t have integrated graphics. Intel’s 8th Gen Coffee Lake series and AMD Ryzen chips have them, but older versions won’t. In addition, some processors don’t even have integrated graphics, so you must buy a dedicated GPU for your system. 

Most of the latest processors are supported with integrated graphics, which are enough to perform all the basic tasks such as web browsing, video streaming, etc. But a dedicated GPU would be the best option if you have a graphic-demanding task.

For example, the Intel processors have different series from i3 to i9. All these series are further divided by different alphabets: K, F, KF, and Non. Here’s why they are divided and which one is the integrated GPU.

Processor Type Feature
K It is unlocked, and you can overclock it.
F It’s not unlocked for overclocking and doesn’t have integrated graphics.
KF It is also unlocked for overclocking and doesn’t have integrated graphics.
Non It has integrated graphics, but you can’t overclock it as it is not unlocked. 

These processors have integrated graphics but are locked and unlocked differently. If you don’t want a dedicated GPU, go for K or Nonseries, as they have integrated graphics.

In conclusion, if you already have a GPU installed, you don’t need to buy a CPU with integrated graphics. But a CPU with integrated graphics would be the best option if you don’t have one. So go for KF or Non-series of Intel, and you will get enough performance for the daily or basic tasks.

Should I Disable Integrated Graphics If I have a Graphics Card?

Integrated graphics is nothing but a small graphics card inside a CPU. If you have a graphics card, you must disable the integrated graphics to prevent your computer system from having conflicts between these two graphics cards. You can also experience deadlock as your computer will start hanging.

If you enable both graphic processors, one may be of higher priority, and the other may be a bit lower. If the integrated graphics is of higher priority, then it will try its best to solve all the graphics-related problems by itself, and the OS may share the same process with both.

Only the RAMs are the only hardware that can work simultaneously, even though they may or may not be the same type. Even the graphics cards of different companies can work simultaneously as well. However, it has been experienced that a CPU with an integrated graphics card causes conflicts with GPUs.

Reasons To Buy CPU With Integrated Graphics Card?

The first reason to buy a CPU with an integrated graphics card is that such a GPU does not need a separate memory bank. It is because it uses the memory or RAM already installed in your computer system. Yes, you should also increase the RAM because some of it will be dynamic in using this CPU.

The second reason to buy a CPU with an integrated graphics card is that you do not need to upgrade your PSU (power supply unit), as the graphics card is inside this CPU. On the other hand, if you buy an external GPU, you must upgrade the PSU and occupy the space on your motherboard.

You may also need some converters to get the display on your display monitor (LCD or LED). The company that sends you the electricity bill will charge more because the external GPUs nowadays consume 70 to 250 watts. And after every 1000 watts, you have to pay the unit charges.

If you are eco-friendly, a CPU with integrated graphics is perfect because it generates less heat than high-end GPUs. It is perfect for people using eco-friendly devices to reduce global warming.

The last but not least reason for buying such a GPU is the increased battery life of your laptop and computer connected to a UPS inverter or other battery-based power source. In addition, the graphics processing system is integrated with your CPU, so it does not need any external power supply.

Which One Will Boost FPS CPU Integrated Graphics or External GPU?

The most advanced CPU with integrated graphics will give you more or less 60 frames per second (FPS) at 100% performance. On the other hand, external GPUs give you 60 FPS only on 8K. And if you use them on lower resolutions, such as 4K or HD, they can double or triple the frame rate.

It is obvious from the comparison above that an external GPU is way better than integrated graphics. But there are ways to boost the FPS using CPU-integrated graphics because increasing framerate depends on not only the hardware but also the settings of your software.

If you are using a video player running video at 8K or 4K, consider lowering the resolution because the higher the resolution is, the less the FPS. The second approach for increasing your frame rate is to allow unlimited or more frame rates from the settings of your game. The last way is to increase the RAM.

The CPU with integrated graphics stores all the graphical data in the system memory before and after processing it. Simply, the system memory is the RAM installed on your motherboard. Please increase the RAM size so more data can be stored in them instead of on the virtual memory that drops FPS.

Does Integrated Graphics Lower CPU Performance?

No, Integrated Graphics do not lower CPU performance; instead, they increase the performance of your CPU by taking responsibility for all graphics-related tasks. As a result, the CPU can perform other tasks, such as executing multi-threaded apps, scheduling the process execution, generating addresses, etc.

Do I Need A CPU With Integrated Graphics If I Have A GPU? |

I recommend purchasing a CPU with integrated graphics if the external GPU is too expensive on your budget. It will be economical and save you power, saving a couple of dollars from your electricity bill. Also, don’t worry about the performance if you do not have high-end software.

Is CPU Integrated Graphics Enough for Gaming?

If you want to play low-spec games, a CPU with integrated graphics is enough. On the other hand, if you are a professional gamer or gaming is your favorite time pass, you need a more powerful GPU. It is because the maximum FPS such a CPU can give is 60.

The CPU with integrated graphics will be unable to handle extreme gaming conditions and become overheated. Without a better cooling system, it can burn out. If you want to play games with higher resolution and texture details, I recommend an external GPU with the official drivers.

Do You Need More RAM For Integrated Graphics?

Yes, you need more RAM for integrated graphics because there is no VRAM inside, unlike the external GPU. The other reason behind this is that the integrated graphic uses the memory of the RAM installed on your motherboard. So increase your RAM for integrated graphics will use it.

The second reason behind installing more RAM is that the operating system (OS), such as Windows 10/11, stays in the RAM as the computer starts until it shuts down. The third reason is that the other software and apps also need a place in the system memory to execute properly.


Choosing between a CPU with integrated graphics and an external GPU depends on your budget, where you want to play games or use software, and your computer’s specs. For example, external GPUs are more powerful but need more power than CPUs with integrated graphics. On the other hand, an integrated graphic is enough for low-spec software/games if it has enough RAM and saves electricity compared to external GPUs.
