We’ll break down the most crucial elements in this article for the best AI-generated image production with Stable Diffusion, assisting you in choosing the hardware that will work best for your needs.

Here is minimum requirements to build pc for stable diffusion

  • CPU: Any Intel CPU or modern AMD.
  • RAM: A minimum of 16 gigabytes of DDR4 or DDR5 RAM.
  • Storage: Upgrade your storage game with a top-performing SATA or NVMe solid-state drive from a reputable brand. Go big with at least 256GB of space and make sure you have a minimum of 10GB free for optimal performance. For the best bang for your buck, consider a massive 1TB drive!
  • GPU: Any GeForce RTX GPU with a minimum of 8 gigabytes of GDDR6 memory.

GPU for Stable Diffusion: Which Graphics Card should you choose?

To make the application more compatible with many devices, the Stable Diffusion team has been working nonstop.

While it has been possible to run Stable Diffusion on a variety of systems, including AMD and older NVIDIA graphics cards, as well as M1 and M2 Macs, it can be difficult to set up and these devices are more prone to experience problems.

As of the time this article was written in December 2022, only RTX NVIDIA GPUs are currently fully supported and compatible with Stable Diffusion.

It is advised to get the most recent model of graphics card when purchasing one to use with Stable Diffusion. It is important to note that older GPU models, even ones with the same amount of video RAM (VRAM), will take longer to produce the same image size.

This is true even for NVIDIA GPUs from the 20, 30, or 40-series with 8 gigabytes of memory. It might be advisable to stay away from older RTX 20-series GPUs if your goal is to build or update a PC exclusively for Stable Diffusion, unless you can locate one for a really good price.

How Much Video Memory (GPU Memory) Do You Need for stable diffusion ?

Stable Diffusion will need more VRAM to meet the burden as your image sizes grow. It is advised to have at least 8 gigabytes of VRAM to ensure smooth functioning.

The RTX 3060 is a potential choice with a reasonable pricing. The RTX 3060 is slower than the 3060 Ti, but it contains 12 gigabytes of VRAM as opposed to the 3080 Ti’s 8 gigabytes. Stable Diffusion is where the additional VRAM will really shine, but speed and gaming performance will suffer as a result.

Top Pick

MSI Gaming GeForce RTX 3060 

  • MSI Gaming GeForce RTX 3060 12GB 15 Gbps GDRR6 192-Bit HDMI/DP PCIe 4 Torx Twin Fan Ampere OC Graphics Card (Ventus 2X 12G OC)

The dereliction settings of Stable prolixity release is designed to induce 256×256 images using 8 GB of VRAM. While this may be sufficient for some systems, you may run into limitations when trying to produce larger images similar as 512×512.

To produce these larger images without making any adaptations to the settings, it’s recommended to have a GPU with at least 12 gigabytes of VRAM or further.

The more memory you have, the better Stable Diffusion can perform. The RTX 4090 is a powerhouse for image generation, providing every gigabyte of VRAM you could possibly need. Remember, the size of your final image is directly related to the amount of VRAM available, so the sky’s the limit!

Should You Use an Optimized Fork of Stable Diffusion?


The GPU support has been greatly expanded by the Stable Diffusion community, opening up this potent technology to more users. More individuals may now take advantage of Stable Diffusion’s advantages and easily produce spectacular photographs thanks to the expansion of GPUs that support it.

Want to take your image generation to the next level?Look no further than the amazing community forks of Stable Diffusion.

They offer additional models and improvements to polish your creations in addition to user-friendly interfaces.

Even users with little VRAM can produce mind-blowingly big photos using these tools. Imagine being able to create 512×512 images with only 4GB of VRAM or much larger images with 8 or 12GB GPUs, all because to community forks.

Get the most out of Stable Diffusion, but also stay safe. Community forks offer amazing features and optimizations but, as with any software modification, there is always a chance that someone may be acting maliciously.

Always be vigilant and if your antivirus software flags a fork as malicious, don’t ignore it. Keep in mind that Stable Diffusion has a good reputation, so any warnings from your antivirus software should be taken seriously, play it safe and avoid it.

With the right hardware, you can optimize your Stable Diffusion experience to the fullest. Instead of worrying about your PC’s performance, you can focus on fine-tuning your prompts to get the best possible results.
