Can the RTX 5060 8 GB run MiniMax H3 (33B)?
Not realistically: the smallest MiniMax H3 file still needs about 21 GB.
Even the smallest file (Q3_K_M, 15.6 GB) needs about 21.4 GB, far beyond 8 GB. It may start with heavy offloading, but this is not a realistic everyday setup. Pick a smaller model or a GPU with more memory.
Also try the INT8 file (34.0 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 48 GB you could run MiniMax H3 at 8-bit or better (INT8, 34.0 GB) with no offloading.

04The text encoder
At 15.7 GB even the smallest Qwen3-VL 32B file is too big for 8 GB, so it runs from system RAM. That slows down reading the prompt, not the picture. Sizes: 16-bit 51.5 GB, INT8 27.1 GB, NVFP4 15.7 GB. Why the encoder does not count against VRAM →

06About the RTX 5060 8 GB
The RTX 5060 8 GB is a Blackwell GPU with FP8 and FP4 hardware: ComfyUI computes Comfy-Org's FP8 files natively here, and NVFP4 files (where a model offers them) are faster still.

07Questions
How much VRAM does MiniMax H3 need?
Around 21.4 GB with the smallest file (Q3_K_M) and 39.8 GB with an 8-bit file (INT8). The full 16-bit file needs about 72.1 GB.
Which MiniMax H3 file should I download for the RTX 5060 8 GB?
Q3_K_M (15.6 GB) from Abiray/MiniMax-H3-GGUF. Load it with Unet Loader (GGUF) from the ComfyUI-GGUF node pack.
