Just like your PC’s system memory, graphics cards and laptop GPUs have their own memory, called VRAM (video RAM). Just like RAM, not having enough VRAM can cause performance problems; Many of the latest games are demanding more and more, making it impossible for gamers to play their games at the highest settings. How much VRAM you have will depend on what GPU you have, and how much VRAM you need will depend on the applications you use.
But how much VRAM do you need, really? Let’s investigate.
Graphics memory is mostly important for gaming, but there are productivity and professional workloads that benefit from masses of VRAM too. More is better for most graphically intensive tasks, but you don’t necessarily need to go out and buy the best graphics card with the most VRAM. In fact, some lower-end cards with lots of VRAM are still slower than higher-end cards with less.
You can play most games, even most modern games, with 8GB of VRAM, so really that should be the lowest you go if buying a new graphics card. However, modern games that are built for the Xbox Series X/S and PS5, regularly exceed 8GB of VRAM even when playing at 1080p. That means that if you have a GPU with only 8GB of VRAM, there will be some new games you can’t play, even with a powerful
With that in mind, if you want to really future-proof your gaming PC, you want at least 12GB of VRAM. That should give you a few years before you start to run into issues with not having enough VRAM for future games. If you opt for more, like the 16GB or more found on the latest generation releases, you’ll be fine for years to come.
As for productivity, Nvidia recommends in its Professional Solution Guide that you need 8GB to 12GB of VRAM to meet minimum requirements. However, you can probably get away with less VRAM. Adobe Premiere Pro’s minimum requirement for VRAM is 2GB, and 4GB to 6GB is recommended. Autodesk AutoCAD’s “basic” spec calls for 1GB of VRAM but recommends 4GB.
It’s ideal to have more memory than you need, and this is especially important for GPUs since you can’t upgrade the VRAM. Based on recommendations from companies like Nvidia and Adobe, you’ll want at least 4GB for light work. If your job is to edit videos in Premiere Pro or to make models in Autodesk Maya, then you’re definitely going to want to spend more to get a GPU with at least 8GB of VRAM, even if it’s not current-gen.
System RAM and VRAM are very similar: They both come in relatively small capacities and they’re really fast. But they’re not quite the same, because system

This isn’t some kind of design oversight or the case of GPU manufacturers wanting you to buy a whole new GPU each time. The real reason is that GPUs can only be paired with certain amounts of

That said, don’t upgrade for VRAM alone. You could “upgrade” an RTX 3070 Ti with 8GB of VRAM to a lower-tier GPU like the RTX 3060 12GB and have more VRAM, but performance will still be worse because the GPU is less powerful. Make sure that any upgrade you do is going to improve performance across the board, not just unlock a few extra settings because it has more VRAM.
