Measured ComfyUI with 16GB VRAM: Images take 5–8 seconds per image, videos take about 2 seconds for 1–5 minutes (0.41.0)
When running ComfyUI on my own PC, what I am most curious about is "how many seconds will this model take on my GPU?" Since internet numbers vary depending on the environment, I measured using the same method on a single PC with 16GB VRAM.
The operating speed of ComfyUI 0.41.0 (Windows portable version, latest as of October 2026) was measured using a single PC with 16GB VRAM.
The measurement environment used an NVIDIA GeForce RTX 4070 Ti SUPER (VRAM 16GB) GPU, Core i7-14700F / 32GB CPU/RAM, and NVMe SSD storage, with PyTorch 2.14.0.
As a result of the measurements, image generation took 5–8 seconds per image, and video generation took about 2 seconds for 1–5 minutes of video.
