In a computer, system memory or RAM is a form of temporary storage. Your processor (processor) will be able to quickly access data when it is needed to process your workloads. The system’s RAM modules can be easily changed or upgraded.
How Much VRAM Do I Need For Gaming (At 1080P, 1440P, 4K)
The amount of VRAM (video random access memory) you need depends on several factors. In this guide, we’ll tell you what those factors are and explain what video memory actually is and how much you need, depending on the games you’re playing, at what resolution and settings.
In short, the way RAM in a computer provides quick access to critical data to run processes is in VRAM. It gives your GPU quick access to the data needed to run graphics processes.
Since VRAM can be found on the graphics card, it can access the data stored on it much faster than the graphics processor, not when the graphics processor tries to retrieve the same data from the system memory or SSD / HDD in your computer.
Unlike RAM, it is no longer possible to add more video memory to your system or graphics card. Finally, VRAM is integrated directly into the graphics cards. The amount of your graphics card is also the amount of video RAM your GPU and system are using – at least until SiVRAM e upgrades your graphics card.
Which factors affect the video ram?
The more video memory you have, the more graphics data your GPU can get quickly and the faster frames can be transferred to the monitor.
Depending on how you use your computer, your system may require more or less video RAM. Here are the most common factors that have the greatest impact on the amount of VRAM needed:
- Your monitor’s resolution
- The games you’ve played
- The settings you play your games with
Let’s take a closer look at these three factors:
Since VRAM is soldered directly to the GPU PCB (circuit board), increasing the VRAM is impossible. However, you may still be able to combine GPU memory if your software supports features like Nvidia’s NVLink.
How much VRAM do You need? An Overview.
For those looking for only short data, we present our table that summarizes the VRAM capacity requirements for various popular workloads.

What is VRAM?
VRAM stands for Random Access Video Memory and serves as fast, temporary storage for the graphics processor on the graphics card.
Before the GPU can process a single frame or a specific scene, VRAM stores textures, models, geometries, and lighting maps, which the GPU then uses to render that particular frame.
After rendering is complete, the graphics card stores the result in VRAM as a frame buffer, which is then sent to the video display to display the final image on the monitor.
When we talk about rendering, it simply means processing (the math) of a graphical computation that, when combined, produces a visual end result.
So the GPU really only does a few calculations on the data stored in the VRAM.
Simplified example: To render (create) a visual image in a computer game or 3D rendering software that can then be displayed on a monitor, here’s what happens:
- Scene data (textures, polygons, animations, lights…) is loaded from the mass memory into the VRAM of your GPU.
- The GPU passes rays through each pixel
- When a ray hits a surface, the GPU checks what polygons, highlights, and textures are associated with that pixel. This data resides in the VRAM.
- When the GPU has finished checking all pixels of that frame, the frame is complete and can be rewritten to VRAM
- The finished frame is displayed on the monitor (or saved to disk)
So why does VRAM need to be soldered to the GPU? Can’t we just create a GPU VRAM slot where we can swap RAM modules like you do with system RAM on your motherboard?
