Can the RTX 3060 Ti 8 GB run Boogu-Image (Turbo)?
Not entirely. Even Q4_1 is 2.0 GB over 8 GB, so ComfyUI keeps part of it in system RAM.
The smallest sensible file, Q4_1 (7.4 GB), needs about 10.0 GB - 2.0 GB more than RTX 3060 Ti 8 GB has. ComfyUI can still run it by streaming part of the model from system RAM. How much slower that is depends on your ComfyUI version, the file format and the PCIe link - see the note below.
Also try the FP8 file (10.3 GB) on this GPU. It does not fit entirely, but a current ComfyUI streams the overflow from RAM and native 8-bit files often beat a small GGUF that does fit. Dynamic VRAM →
01With more VRAM
With 16 GB you could run Boogu-Image at 8-bit or better (Q8_0, 11.6 GB) with no offloading: for example on the RTX 5080 16 GB, RTX 5070 Ti 16 GB, RTX 5060 Ti 16 GB.

04The text encoder
Take the smallest Qwen3-VL 8B file (6.3 GB): it is the only one that fits in 8 GB on its own. Sizes: FP8 10.6 GB, NVFP4 6.3 GB. Why the encoder does not count against VRAM →

06About the RTX 3060 Ti 8 GB
The RTX 3060 Ti 8 GB (Ampere) has no FP8 compute. FP8 files still load and save memory, but ComfyUI converts them back before the maths, so there is no speed gain - Q8_0 GGUF is the closer-to-original 8-bit choice. ComfyUI can compute INT8 files natively on NVIDIA, which is worth a try where a model offers one.

07Questions
How much VRAM does Boogu-Image need?
Around 10.0 GB with the smallest file (Q4_1) and 12.9 GB with an 8-bit file (FP8). The full 16-bit file needs about 23.2 GB.
Which Boogu-Image file should I download for the RTX 3060 Ti 8 GB?
Q4_1 (7.4 GB) from realrebelai/Boogu-Image-Turbo_GGUFs. Load it with Unet Loader (GGUF) from the ComfyUI-GGUF node pack.
FP8 or Q8_0 for Boogu-Image on the RTX 3060 Ti 8 GB?
Q8_0 (11.6 GB). The RTX 3060 Ti 8 GB has no FP8 maths, so FP8 (10.3 GB) only saves memory and is a step further from the original.
How much do I need to download for Boogu-Image on the RTX 3060 Ti 8 GB?
18.2 GB: boogu-turbo-dit-Q4_1.gguf, qwen3vl_8b_fp8_scaled.safetensors, flux1_vae_bf16.safetensors.
