Memory Size [VRAM]6 GB
Clock1365 MHz – 1680 MHz
Process Size12 nm
TDP160 W

When it comes to running Stable Diffusion on a budget, the GeForce RTX 2060 is the best option. As the most budget-friendly GPU on our list, it won’t break the bank but still packs a punch when it comes to AI tasks. With a clock of 1365 MHz – 1680 MHz and 6GB of VRAM, it meets the minimum requirements for running Stable Diffusion.

One of the biggest benefits of the RTX 2060 is its relatively low power consumption with a TDP of only 160W. This means that it won’t be a huge burden on your electricity bill while running Stable Diffusion. However, its 6GB of VRAM may become a limitation if you’re working with particularly large image sizes.

Overall, if you’re on a tight budget but still want a solid GPU for Stable Diffusion, the RTX 2060 is the best choice. However, if you need more VRAM or plan on working with larger image sizes, you may want to consider a higher-end option. It’s also worth noting that the newer 30 and 40-series GPUs from NVIDIA will likely offer even better performance for running Stable Diffusion, but they come at a higher price point.

2. AMD Radeon RX 6600 XT

Memory Size8 GB
Clock1968 MHz – 2359 MHz
Process Size7 nm
TDP160 W

The Radeon RX 6600 XT is designed exclusively for gaming and other demanding tasks, and it stands out from the crowd with its impressive 8 GB of VRAM. This makes it a great choice for running Stable Diffusion, as this AI model requires 6GB or more of memory to function properly. With its 7 nm process size, clock speed up to 2359 MHz as well as a TDP rating of 160 W (thermal design power), it provides plenty of performance in terms of both graphics output and processing power – perfect for running Stable Diffusion.

As this particular GPU comes at an affordable price point too, you won’t need to break the bank to reap the benefits that AMD has on offer here. Plus, having access to 8 GB rather than 6 GB is always welcome due to increased performance overall – which goes hand-in-hand with running high demands models such as Stable Diffusion successfully.

3. AMD Radeon RX 6650 XT

Memory Size8 GB
Clock2055 MHz – 2410 MHz
Process Size7 nm
TDP176 W

Next up, The Radeon RX 6650 XT from AMD is also a great choice for running Stable Diffusion with a budget GPU since it comes with 8GB of VRAM. It features the 7nm RDNA 2 architecture, which makes it highly efficient. Additionally, its core clock runs from 2055 MHz to 2410 MHz and has a TDP of 176W. That power gets you beautiful performance when running any Stable Diffusion variations.

This kind of memory size coupled with its powerful core clock makes it capable of producing high-quality images in 15 seconds or less; however, if you use other applications that involve intensive graphic processes then its capabilities will greatly benefit you as well.

The interesting fact about this affordable graphics card is that unlike NVIDIA GPUs, which are more suitable for AI operations such as Stable Diffusion due to their engines and libraries used off-the-shelf by many researchers today — AMD’s GPUs actually can be tweaked to run these kinds of models too! All in all, if you’re looking for an efficient way to get results fast while on a budget, investing in a Radeon RX 6650 XT is definitely worth considering!

4. Nvidia GeForce RTX 3060

Budget GPU for Stable Diffusion
Memory Size12 GB
Clock1320 MHz – 1777 MHz
Process Size8 nm
TDP170 W

The GeForce RTX 3060 is considered the overall best GPU for Stable Diffusion, according to the Stable Diffusion community. It is also one of the most positively talked-about budget GPUs among its users. The GPU comes with a massive 12GB memory size, which is more than enough to handle Stable Diffusion’s needs. The clock speed of the GPU ranges from 1320 MHz to 1777 MHz, making it a powerful option for running AI models. The process size is 8 nm, which is quite efficient, and the TDP is 170 W.

When it comes to running Stable Diffusion, the GeForce RTX 3060 is a great choice for several reasons. It provides more than enough VRAM to handle Stable Diffusion’s requirements, making it a good option for those who want to run the model quickly and efficiently. The clock speed is also quite impressive, and the process size and TDP make it a cost-effective option for users who want to save on energy costs.

However, one potential downside to the GeForce RTX 3060 is that it might not be the most affordable option on the market. While it is a budget GPU, it is still relatively expensive compared to some other options. Additionally, its high memory size might not be necessary for everyone, depending on the size of the images they’re generating.

5. Nvidia GeForce RTX 3060 Ti

Memory Size8 GB
Clock1410 MHz – 1665 MHz
Process Size8 nm 200 W
TDP200 W

If you’re looking for a reliable GPU to run Stable Diffusion, then the GeForce RTX 3060 Ti is an excellent choice. This GPU has 8GB of VRAM, which is perfect for running AI models like Stable Diffusion with ease. It comes with the latest NVIDIA Ampere architecture and 3rd Gen Tensor Cores, which makes it an ideal choice for AI-related tasks.

The only downside of the GeForce RTX 3060 Ti is it’s more expensive than the RTX 3060 and comes with only 8GB of VRAM which is less than the 3060. However, it is an excellent choice for running Stable Diffusion and other AI models.


In conclusion, there are several budget-friendly GPUs that can effectively run Stable Diffusion, an open-source AI model that generates high-quality images from text instructions. While the minimum requirement is 6GB of VRAM, GPUs like Nvidia GeForce RTX 2060, AMD Radeon RX 6600 XT, AMD Radeon RX 6650 XT, and Nvidia GeForce RTX 3060 come with more VRAM and clock speeds that make them ideal for running Stable Diffusion. The best choice for a budget GPU would depend on the user’s specific needs and preferences. However, regardless of the GPU chosen, Stable Diffusion can produce high-quality images from text instructions, making it an impressive tool for researchers, artists, and developers.
