In this article, we will be comparing the speed and performance of Comfy UI, Automatic 1111, and Invoke AI. We will be conducting a simple test to determine which platform is the quickest. While this may not be a complex benchmark test, it will provide valuable insights into the speed differences among these platforms.

Test Setup

To conduct the test, we used the same model, MBB XL, without any refinements for the sampler. The Euler ancestral CFG Scale was set at 7, and we performed 30 steps. We ran three generations of 768 by 1024 and 1024 by 1024. The hardware used for the test includes a Ryzen 5800 X processor, an NVIDIA 3060 TI graphics card with 8GB VRAM, and 32GB of system RAM. It's important to note that while there are variables such as overclocking and faster RAM that can affect performance, we wanted to provide a comparison using the hardware at HAND.

Performance Comparison

3.1 Automatic 1111

Running the 768 by 1024 test on Automatic 1111, we observed an average time of approximately 27.33 seconds. The subsequent runs showed consistent results, with times ranging from 27.55 to 28 seconds. When switching to 1024 by 1024, the average time improved to 36 seconds, a noticeable difference from the initial 40 to 45 seconds. However, with only 8GB VRAM, users may not experience significant speed improvements with this platform.

3.2 Invoke AI

Surprisingly, Invoke AI showcased significantly faster performance compared to Automatic 1111. In the 768 by 1024 test, the average time was about 18.83 seconds, proving to be a considerable improvement. Even in the 1024 by 1024 test, the average time was 24.44 seconds, which was approximately 12 seconds faster than Automatic 1111. Invoke AI's speed and consistency make it a pleasure to use.

3.3 Comfy UI

Moving on to Comfy UI, we found that it offered even faster performance than Invoke AI. In the 768 by 1024 test, the average time was 16.16 seconds, a mere two seconds faster than Invoke AI and considerably faster than Automatic 1111. Similarly, in the 1024 by 1024 test, the average time was 21.47 seconds, which was around 15 seconds faster than Automatic 1111 and three seconds faster than Invoke AI. Comfy UI stands out as an impressive option in terms of speed.

SD Next vs Automatic 1111

While we did not test SD Next for this video, it is worth mentioning that many users claim it to be significantly faster than Automatic 1111. Exploring SD Next's performance and comparing it to Automatic 1111 could provide further insights. However, we cannot comment on its speed at this time.


In our simple benchmark test, Comfy UI showed impressive speed and outperformed both Automatic 1111 and Invoke AI. Invoke AI also delivered noteworthy speed improvements over Automatic 1111. Although Automatic 1111 may have its limitations due to VRAM, Comfy UI and Invoke AI proved to be reliable options for users seeking faster performance. We recommend exploring SD Next for users looking for an alternative to Automatic 1111.


Q: Can I expect the same performance improvements with different hardware configurations? A: While faster hardware can potentially enhance performance, the speed differences observed in this test may not drastically change. Comfy UI and Invoke AI have shown consistent speed improvements compared to Automatic 1111.

Q: Are there any other factors besides hardware that can affect the speed of these platforms? A: Yes, factors such as software optimizations, system settings, and the complexity of the task being performed can impact the speed of these platforms. It is recommended to ensure that the platforms are up to date and properly configured to achieve optimal performance.

Q: Can Comfy UI and Invoke AI be used for gaming purposes? A: While these platforms are primarily geared towards their specific applications, they can potentially offer improved performance for certain gaming tasks. It is recommended to consult the respective platform's documentation or user community for more information on gaming performance.

Q: Are there any disadvantages or drawbacks to using Comfy UI or Invoke AI? A: While both Comfy UI and Invoke AI have showcased impressive speed improvements, they may require a learning curve to fully utilize their capabilities. Users may need to invest time in understanding the platform-specific workflows and features. Additionally, certain tasks may still benefit from using Automatic 1111 or other alternative platforms.

Q: Can I use Comfy UI or Invoke AI for professional purposes? A: Yes, both Comfy UI and Invoke AI can be utilized for professional purposes, depending on the specific requirements of the task. These platforms offer advanced features and speed improvements that can enhance productivity in various professional applications.
