What is a Dedicated Graphics Card? Do I Need One?

Share on:

Dedicated Graphics Card is a dedicated piece of hardware for graphics processing for your device. These are usually used in Personal Computers. Dedicated Graphics Card comes with its own unique pros and cons which we will be discussing later in the article. It has a high image rendering capacity and its parallel operation makes it way faster one’s expectation. The dedicated graphics card is a must for graphics designers and hardcore gamers.

You might have heard the names of both Integrated Graphics Card and Dedicated Graphics Card and might be having a bit of confusion regarding these two. There is some fundamental difference between these two. Before installing high graphic intensive software or games, you may like to check the graphics card your computer has already.

What Is Graphics Card?

Graphics card is a combo of GPU and many other peripherals. Graphics Card excels in processing for display output. But even though it excels in the field of graphics processing it is used for some other purposes like it is used for vector processing.  Its special ability to process multiple data simultaneously gives it a special place in the world of computing. It is mandatory for rendering 3D animations.

Its uniqueness gave it a place in many of the fastest computers in the world. It goes without saying how much it has owned the heart of the gamer around the world. But the question still lies ‘Is it worth all those bucks?’.

Dedicated Graphics Card

Dedicated Graphics Card is what the name means. It is a dedicated piece of Graphics Card that won’t be using the memory, RAM, and other peripherals of your computer but it does the trick quite awesomely. It comes with its own built-in video memory, RAM. It won’t be slowing down your computer. It will be worth every penny if you are a hardcore gamer or a professional graphics designer. We suggest you know how to do a GPU stress test.

But you should obviously go through a couple of things before you end up buying one of these. What are you going to use your PC for? It has earned an indelible place in the computing world nothing has come close to be thought of as its replacement.

Parts of Dedicated Graphics Card

Graphics Card is one of the most complex devices you will find in this computing era. It has to have many components that are working simultaneously to achieve the feet. Some of the core components are the Graphics Processing Unit, Video BIOS, Video Random Access Memory, and the Output Interface. These components are working to do what the Graphics Card is doing. You might have got an inkling of what each one of these components does solely from its names.

  1. GPU: The Graphics Processing Unit is what the name points to it does the processing and give instructions. It is seating on the throne of Graphics Card taking the decisions. Many confuse the GPU with the Graphics Card whereas the two of them are totally different things. The Graphics Processing Unit is the processing unit of the Graphics cards which does the calculations for the graphics card to render the images to display output.
  2. Video BIOS: It is what the name suggests, the Basic Input /Output System for the video chipset of the Graphics card. What every BIOS does, in general, is that it helps the hardware to get started and provides a medium for interfacing with other required hardware. Here in case of Video BIOS, it does the same thing and in the meantime for meeting the requirements for a medium for interfacing in has some built-in function.
  3. Video Memory (VRAM): For every possible kind of operating hardware, a memory is a must. Video memory is the memory of the Graphics Card. The higher the Video Memory the high functioning is the graphics card is a very wrong concept. But it is indeed a limiting factor for the Graphics Card. In the very recent past, the Video Memory on the motherboard of a PC was a couple of megabytes whereas in the latest Graphics Card of the tech world Video Memory of Graphics Card is hitting in the range of Gigabytes.
  4. RAMDAC: RAMDAC is the acronym for Random-Access Memory Digital-to-Analog Converter. The name itself provides the information that it is the combination of Random Access Memory and the Digital to Analog Converter. There is a combination of three Analog to Digital Converters and a Static Random-Access Memory. The RAM serves the purpose of storing colors and in turn giving voltage amplitudes for running color monitors.
  5. Output Interface: Output interface helps connect the graphics card with some other required hardware. This is the part of the graphics card that enables get datum to and from the PC through its motherboard. Currently, there are two basic types of output interface for graphics i.e. PCI Express and the AGP. You will have to make sure that you are getting the motherboard with the same type of interface for the graphics card.
  6. HDMI port: HDMI the acronym for High Definition Multimedia Interface indicates that it is an interface for both input and output. It’s one of the most popular display interfaces. This interface enables the hardware to transmit video and audio datum. Some of the latest versions of graphics come with a built-in mini HDMI port.
  7. Display Port: This is another display interface like the HDMI but comes with some basic differences to the previously discussed HDMI. This fact might not come in much of a use to you but to some it will that is HDMI is proprietary whereas Display Port is not. Display Port came into existence in 2006.


Well, it has become quite obvious what this facilitates. This monster enables you to do some heavy-duty graphics designing. It renders graphics at a very high speed than your everyday integrated graphics processing unit which is a must for gamers.


Dedicated Graphics Card obviously comes with a bunch of pros that’s why it’s this big of a deal. It uses its own built-in components, not touching any of your computer’s memory or other peripherals. It renders graphics faster than a human can imagine.


Everything has its ups and downs. Dedicated Graphics Card consumes a lot of your power and battery life so it is irritating to gamers using a laptop with a dedicated graphics card. They have to constantly switch between their integrated and dedicated graphics card for the sake of their battery life.
In the meantime, it also releases a lot of heat which has to be managed with extra cooling fans.

Summing Up

At the end of the day, the dedicated graphics card is a separate processing unit that doesn’t use any of the components of your computer. Making your computer fast enough for gaming or graphics designing. It has its pros, cons, and unique features. Graphics Card includes GPU, Video BIOS, Video Memory(VRAM), RAMDAC, Output Interface, and interface for transmitting as receiving data like HDMI or Display Port.
