You’ve seen while looking for a new graphics card that the “Memory” specification has always been present. To add, it’s not uncommon to see many different memory capacities for a given graphics card model. But if your computer has enough RAM, why do graphics cards have memory? Almost everyone in our world has a cause that is most important to them. For Gollum, it was his priceless ring of power; for Romeo, it was his beloved Juliet; for gamers, it was the graphics card.
Not only for gamers; have you needed a graphics card if you deal with video editing or AI acceleration? And the graphics card’s RAM is a component of it. You may ask yourself, “Why do I need extra memory specifically for the graphics processor when I already have a gigabyte of hard drive space and many sticks of RAM?”
The graphics memory, however, has to hold certain unique information that the other memories cannot. I’ve outlined the necessity for memory for graphics cards in this article, its characteristics, and recommended memory requirements.

Why Do Graphics Cards Have Memory?
Textures and post-processing must always be on the graphics card in the VRAM (Video Random Access Memory). This RAM is only utilized by the graphics processor (GPU). Because of this, graphics processing is sped up, made more accessible, granted greater bandwidth, and made much easier to design.

Here are some reasons why graphics cards need memory:
Keeping graphic data
Your graphics processing unit (GPU) performs tons of processes per second to show a crisp picture on the screen. There must be a place to store the information needed for the calculations. Unsurprisingly, your central storage (SSD/HDD) is too sluggish and far away to use.
Your main storage drive sends all the information needed to produce a frame to Memory. Since the data is for graphics, the CPU sends it to your VRAM. It remains there till it is required. The ideal illustration of essential graphical data is textured. Your games seem to be a collection of randomly generated geometric forms without any sense of immersion.
A 3D model has a texture that includes anything from grass and stones to different parts of your weapons. Compare video game graphics to hundreds of high-quality pictures. Materials are initially stored in the game folder; thus, they must stay in your VRAM for rapid access when required. The CPU transfers data to VRAM rather than RAM when it detects that it is of a graphics nature, such as textures, mesh, processors, or vector graphics. There it is kept until it is required.

Pre-rendered Frame Storage
After processing a frame, the GPU delivers data to the VRAM and moves on to the next shot. The majority of graphics cards nowadays contain two caches. The first buffer shows the previous frame to your monitor until the second buffer gets the subsequent edge from the VRAM. The second buffer presents the frame, while the first buffer obtains the next frame when this operation is complete.
Typically, the pre-rendered frame is one frame. However, specific graphics drivers let you switch to two frames.

To prevent signal loss
By averaging the colors of the pixels in that area, anti-aliasing helps to eliminate the jagged corner. It creates a crisp and streamlined frame.
Does Graphics Card Memory Size Matter?
The performance of the GPU is impacted by the RAM available on the video card. The screen scale, textures, reflections, and other graphical parameters are limited by the memory limitations of your graphics card. To assist you in better grasping how graphics cards function, let’s use a simple comparison. The graphics card memory is inside the automobile, and your GPU is its engine.
You can only go at the engine’s speed, but if you have a bigger vehicle, you can transport more people. Because of the increased efficiency, you can travel with more passengers. Similarly, how many frames per second you can obtain at a given graphics level depends on how well your GPU performs. It’s frequent to wonder Why do Graphics Cards Have Memory. The answer is that it has a multitude of advantages.

How Much VRAM Do You Need?
To play a game at 1080p low settings, you want at least 4GB of VRAM and 6GB at high settings. Between 8GB and 12GB will do for 1440p. Furthermore, you need at least 12GB VRAM for 4K gaming.
You can use the following guidelines to determine your VRAM size:
- 1GB-2GB of VRAM
If you use Photoshop and play older or eSports games, invest in a graphics card with this VRAM. With this VRAM, you cannot play any AAA games from the present era, while some could be playable on low settings.
- 3GB to 6GB VRAM
These VRAMs are appropriate for video editing, game development, and gaming. You will want at least 6GB VRAM to play games in 1080p at high settings.
- 8GB to 12GB of VRAM or more
These VRAM configurations are for gamers. You need a minimum of 12GB VRAM to play games at 4K.

Can You Increase VRAM
Outside graphics cards, the memory is soldered into the PCB and cannot be changed. If your graphics card is internal, you can expand your video memory (VRAM) via the system’s BIOS.
Purchasing a new graphics card with more memory is the most straightforward method to improve VRAM. However, if purchasing is out of the question, you may utilize the BIOS to boost VRAM. Check the memory capacity of your integrated graphics card before adding more RAM. A common query is, “Why Do Graphics Cards Have Memory?” The explanation is that it has a wealth of advantages.
Here are the steps to check integrated graphics card memory:
- On Windows, click the icon.
- Access Settings.
- Choose Display. Scroll down and choose advanced display options under the Display menu.
- To see the adapter’s properties, click.
It will open a new window that displays the RAM on your graphics card. The pop-up window’s allocated memory number does not affect how well your PC handles graphics. It exists in case any games or applications check the amount of VRAM on your system.
Installing programs that need more VRAM will require increasing this number. Keep in mind that performance won’t be improved by doing this.

GPU Memory vs. RAM
There are numerous similarities between system RAM and GPU memory, often known as VRAM. First of all, they are both random-access memories, allowing for the writing and reading of any kind of data.
VRAM is often divided into many pieces, each of which stores a particular kind of data. Frame buffers, depth buffers, shadow maps, textures, modeling, and other assets are just a few examples of the things that are kept in VRAM.
All the data that your CPU requires or could need shortly is stored in your system RAM briefly. The applications and data that are currently in use are also stored in RAM. For instance, all Chrome tabs are kept in RAM, enabling blazing-fast tab changing.
Memory bus width, frequency, and GDDR (or HBM) version all affect VRAM speed. In terms of frequency, VRAM effortlessly achieves rates of 10,000–15,000 MHz. RAM is substantially more sluggish. Depending on the DDR type and clock speed, clock rates typically vary from 2400 to 6400 MHz.
Moreover, VRAM has a substantially greater maximum data transmission rate.
Frequently Asked Questions
What is the purpose of video card memory?
The goal of VRAM is to guarantee the consistent and fluid operation of the graphics display. Programs that show intricate picture patterns or produce three-dimensional (3D) constructions made of polygons place the most emphasis on it. VRAM is often used for programs like video games or 3D graphic design software.
How durable are graphic cards?
GPUs generally last between 5 and 8 years, give or take, assuming continued usage and proper maintenance. More if the card is well-maintained and seldom ever used. A solid mid-level GPU today would only truly function at a mid to high level for around three years.
Can VRAM be expanded?
You can only specify a maximum memory limit for your VRAM; there is no way to preset its value. The shared memory used by the graphics processing unit (GPU) is assigned manually based on several variables; it is not a dedicated memory.
