Stable Diffusion requires a minimum of 8GB of GPU VRAM (Video Random-Access Memory) to run smoothly. You can use Stable Diffusion locally with a smaller VRAM, but you have to set the image resolution output to pretty small (400px x 400px) and use additional parameters to counter the low VRAM. The more VRAM you have, the bigger (resolution-wise) and more complex images you can create with it.

Key Takeaways

  • 8GB of GPU VRAM (minimum recommended amount)
  • 10GB of GPU VRAM (A good amount of VRAM, but still lacks in performance)
  • 16GB+ of GPU VRAM (When you are serious about AI art)

Check out: Stable Diffusion Requirements for optimal results.

While Stability AI recommends 6.9GB of VRAM to run Stable Diffusion, I’ve been able to run Stable Diffusion with 6GB GPU VRAM (NVIDIA GeForce GTX 1660 Ti with Max Q-Design). Nvidia graphics cards are currently favored for AI art generation.

Hardware Requirements For Generating AI Art With Stable Diffusion

When it comes to generating AI art with Stable Diffusion, the hardware requirements are quite specific. To achieve optimal results, you’ll need a CPU capable of handling multiple threads and a GPU with enough VRAM for generating images. You’ll also need sufficient SSD storage to store your artwork.

CPU Requirements

For best results when generating AI art with stable diffusion, you should use a processor that has at least four cores and eight threads or more. This will allow your computer to handle multiple tasks simultaneously without slowing down or crashing due to overloading. Even though VRAM is the most important part of using the AI art generator, you don’t want your PC to lag while doing something else while AI art is being generated.

GPU Requirements

When creating AI art using stable diffusion, you must have a graphics card with enough VRAM (video memory) to render high-resolution images quickly and efficiently.

The amount of VRAM needed depends on the complexity of the artwork being generated; however, 8GB is usually sufficient for most projects. If you plan on creating more detailed works of art (higher sampling, more batches, etc.), then 10GB or higher may be necessary.

In addition to having an adequate GPU setup, it is also essential that your computer has enough RAM (random access memory) available for all processes related to generating AI art.

Generally speaking, 8GB should suffice, but 16GB (for those who truly want to generate AI art) would provide even better performance when dealing with higher steps count and HiRes Fix options.

Understanding Stable Diffusion

Diffusion is a process of digital image manipulation that uses algorithms to create unique and visually appealing images. It is used by graphic designers, digital artists, and small online business owners (there are plenty of Etsy stores selling AI art already) to create eye-catching visuals for their projects.

What is Stable Diffusion?

Image source

Stable diffusion is an algorithm-based method of manipulating digital images, the end result being AI-generated art. Stable diffusion works by applying mathematical equations to the pixels in an image, resulting in a new version with interesting visual effects and outputs.

This technique can be used to add texture or depth to an existing photo or illustration, as well as create entirely new artwork from scratch. The results are often unpredictable but can produce stunningly beautiful visuals that would otherwise be impossible without this technology.

How Does it Work?

The stable diffusion process begins with a source image that can be provided by the user or generated using art software like Adobe Photoshop. Once the source image has been selected, you can basically throw it to Stable Diffusion and get something totally new out of the software.

The end result will vary depending on how much control was given over the parameters during setup and what kind of effect was desired from the start. Combine Stable Diffusion with different models, such as ANYTHING V3, with correct parameters, and the results start to look just stunning.

Benefits Of Stable Diffusion

The main benefit of using stable diffusion for digital artwork creation is its ability to quickly generate high-quality visuals with minimal input from the artist. All they need to do is set up some basic parameters before letting the algorithm take care of everything else.

You can execute Stable Diffusion locally, and thus you can use it for free. There are no monthly fees or limits to how much you can use it. There are plenty of other AI art generators that charge a fee for using them, such as Nightcafe. With Stable Diffusion, the source code is free for anyone to improve and study. One of the biggest benefits of Stable Diffusion is that it’s developed by hundreds of contributors, and so the development speed is phenomenal.


How Much GB Is Stable Diffusion?

The file size of Stable Diffusion v1.5 model is 4.27GB, but it depends on what kind of models you install on your computer. The basic setup (including Python, Git for Windows, and WebUI) takes roughly 9.37GB of HDD/SDD space.

Can My PC Run Stable Diffusion?

Yes, your PC can run Stable Diffusion if you have roughly 10GB of HDD/SDD space and roughly 8GB of GPU VRAM. You must also reserve some space for installing Git and Python, as Stable Diffusion requires those to work properly.

You can run Stable Diffusion on Windows, Linux as well as on Mac. Mac needs some additional setups compared to Windows. You can read more about Stable Diffusion and its requirements here.

What Is A Good Amount Of VRAM To Have?

8GB and more is a good amount of VRAM to have when running Stable Diffusion. If you are serious about AI art, then having 16GB of VRAM might be a better option. 16GB enables you to run Stable Diffusion faster and also allows you to produce larger images and more intricate results with it.

Can I run Stable Diffusion without a graphics card?

No, Stable Diffusion requires a graphics card to run. This is because the software relies on the GPU to calculate and render digital AI art. Without a dedicated graphics card, achieving the desired performance and quality levels expected from this type of application would be impossible.

Some features may not even work at all without a suitable GPU installed in your system.



Digital Artist

I’m a digital artist who is passionate about anime and manga art. My true artist journey pretty much started with CTRL+Z. When I experienced that and the limitless color choices and the number of tools I could use with art software, I was sold. Drawing digital anime art is the thing that makes me happy among eating cheeseburgers in between veggie meals.
