It’s ideal to have more memory than you need, and this is especially important for GPUs since you can’t upgrade the VRAM. Autodesk AutoCAD’s “basic” spec calls for 1GB of VRAM but recommends 4GB. Adobe Premiere Pro’s minimum requirement for VRAM is 2GB, and 4GB to 6GB is recommended. However, you can probably get away with less VRAM. AMD’s top-end PRO W6800 is equipped with 32 GB of memory, while Nvidia’s RTX A6000 has 48GB, which is certainly overkill for most users.Īccording to Nvidia’s Professional Solution Guide, modern GPUs equipped with 8GB to 12GB of VRAM are necessary for meeting minimum requirements. But just like gaming GPUs, workstation GPUs often come with amounts of VRAM that makes sense, and across the board, you’ll find that these kinds of GPUs tend to have more VRAM than their gaming counterparts, at least at the high end. Professional work done with professional software like AutoCAD or Adobe Premiere Pro will likely demand more VRAM than most games. Only the latest AAA games running with everything turned up to ultra at 4K resolution demand anything close to that much VRAM, and even then, you’d need a super high-end card, so making sure your GPU is current and as high-end as you need and can afford is more important than worrying about VRAM. However, there is the RTX 3060, which has an insane 12 GB of VRAM, just like the RTX 3080 Ti, and its $329 MSRP puts it firmly in the midrange. In these cases, having a higher-end GPU might be necessary because they don’t usually put lots of VRAM on lower-end GPUs. Some games aren’t optimized very well, meaning you’ll have to play with graphics settings to get decent performance, and if you’ve ever modded a game like Skyrim, you’ve probably seen graphics mods that say you need a GPU with lots of VRAM. Besides, it’s much more likely the actual GPU itself is going to reach the end of its rope before you need more VRAM. There might be some cases where having more memory would be beneficial, but AMD, Nvidia, and game devs are pretty good at using hardware and software tricks to conserve memory. Whatever VRAM is on your GPU is probably all that you’re going to need. If you’re a gamer, good news: Gaming GPUs tend to be designed pretty sensibly. CPUs can tolerate pretty crazy RAM configurations, but GPUs can’t. The real reason is that GPUs can only be paired with certain amounts of RAM, depending on memory bus width. This isn’t some kind of design oversight or the case of GPU manufacturers wanting you to buy a whole new GPU each time. This means whatever GPU you buy, you’re stuck with however much memory it has. But VRAM is not user upgradeable (outside of extreme hardware modification with a soldering iron). It’s trivial to upgrade system RAM - you just plug in a new stick or replace an existing one.
