Key Takeaways
You will want a PC with a contemporary AMD or Intel processor, 16 gigabytes of RAM, an NVIDIA RTX GPU with 8 gigabytes of reminiscence, and a minimal of 10 gigabytes of free space for storing obtainable. A GPU with extra reminiscence will be capable of generate bigger photos with out requiring upscaling.
Steady Diffusion is a well-liked AI-powered picture generator which you could run by yourself PC. However what are the minimal specs to run Steady Diffusion, and what elements matter essentially the most?
What PC {Hardware} Does Steady Diffusion Require?
The only most important element for Steady Diffusion is your graphics card (GPU). Steady Diffusion — at the very least the first model — runs nearly completely in your GPU. That signifies that different system elements, like your CPU, RAM, and storage drives, do not matter practically as a lot.
Neighborhood forks typically change how Steady Diffusion operates and will lead to a higher demand in your CPU and RAM than the official Steady Diffusion launch.
Typically talking, listed below are the minimums specs we would advocate in the event you’re constructing a brand new PC with Steady Diffusion in thoughts:
- CPU: Any fashionable AMD or Intel CPU.
- RAM: A minimal of 16 gigabytes of DDR4 or DDR5 RAM.
- Storage: Any SATA or NVMe solid-state drive from a good firm that’s 256 gigabytes or bigger. You want at the very least 10 gigabytes of free house obtainable. Usually, one terabyte drives supply the most effective value per gigabyte of storage.
- GPU: Any GeForce RTX GPU with a minimal of 8 gigabytes of GDDR6 reminiscence.
What Sort of Graphics Card (GPU) Do You Have to Run Steady Diffusion?
The Steady Diffusion group has labored diligently to increase the variety of gadgets that Steady Diffusion can run on. We have seen Steady Diffusion working on M1 and M2 Macs, AMD playing cards, and previous NVIDIA playing cards, however they are usually tough to get working and are extra liable to issues. RTX NVIDIA GPUs are the one GPUs natively supported by Steady Diffusion on the time this text was written in December 2022.
Any of the next NVIDIA RTX playing cards will work out of the field:
- RTX 2060 (12GB), RTX 2070, RTX 2070 Tremendous, RTX 2080, RTX 2080 Tremendous, RTX 2080 Ti, or RTX Titan
- RTX 3060, RTX 3060 Ti, RTX 3070, RTX 3070 Ti, RTX 3080, RTX 3080 (12GB), RTX 3080 Ti, RTX 3090, or RTX 3090 Ti
- RTX 4090, RTX 4080, and future 40-series GPUs
The RTX 3050 would work too, however it’s tough to advocate given how it’s priced in comparison with the RTX 3060 12 gigabyte variant.
Attempt to purchase the most recent GPU you may. Any of the 20, 30, or 40-series GPUs with 8 gigabytes of reminiscence from NVIDIA will work, however older GPUs — even with the identical quantity of video RAM (VRAM) — will take longer to provide the identical dimension picture. Should you’re constructing or upgrading a PC particularly with Steady Diffusion in thoughts, keep away from the older RTX 20-series GPUs except you discover a unbelievable deal on one, since they’re considerably slower.
How A lot Video Reminiscence (GPU Reminiscence) Do You Want?
The bigger you make your photos, the extra VRAM Steady Diffusion will use. The minimal quantity of VRAM you need to take into account is 8 gigabytes.
The unmodified Steady Diffusion launch will produce 256×256 photos utilizing 8 GB of VRAM, however you’ll possible run into points making an attempt to provide 512×512 photos. If you wish to go to 512×512 photos with out fidgeting with the settings, get a GPU with 12 gigabytes of VRAM or extra.
The RTX 3060 is a possible possibility at a reasonably low value level. The RTX 3060 is slower than the 3060 Ti, nonetheless, the RTX 3060 has 12 gigs of VRAM, whereas the 3080 Ti solely has 8 gigs. The additional VRAM will actually shine in Steady Diffusion, however that comes on the expense of velocity and gaming efficiency.

A GeForce RTX GPU with 12GB of RAM for Steady Diffusion at an excellent value.
With regards to extra VRAM and Steady Diffusion, the sky is the restrict — Steady Diffusion will gladly use each gigabyte of VRAM obtainable on an RTX 4090. All of it will depend on the scale of the picture you are producing.
In fact, there are all types of optimized forks that let you get away with a lot much less VRAM on the expense of velocity, however if you wish to make certain it will work, follow RTX NVIDIA playing cards which have at the very least 8 gigabytes of reminiscence.
Ought to You Use an Optimized Fork of Steady Diffusion?
In a phrase: Sure.
The Steady Diffusion group has carried out a unbelievable job increasing the variety of supported GPUs to make Steady Diffusion extra accessible.
Neighborhood forks typically embrace a consumer interface, extra fashions to refine your creations, and optimizations that let you generate bigger photos with much less VRAM. Some customers have been capable of generate 512×512 photos with as little as 4 gigabytes of VRAM utilizing group forks. The identical optimizations enable customers with 8 and 12 gigabyte GPUs to provide considerably bigger photos.
The consumer interface is a good characteristic too, because it makes utilizing Steady Diffusion simpler. It makes producing AI video with Steady Diffusion doable too.
Simply watch out. A lot of the modifications you will discover are written by well-intentioned fanatics, however there may be all the time the likelihood that somebody is appearing maliciously. In case your antivirus flags a Steady Diffusion fork as malicious, do not ignore it. Steady Diffusion isn’t identified for producing false positives from antivirus software program, so any warnings you obtain ought to be taken severely.
As soon as you’ve got bought the proper {hardware}, you may spend time optimizing your Steady Diffusion prompts as a substitute of your PC.
