Fooocus strips Stable Diffusion down to its essentials. One text box, one generate button, Midjourney-quality results without the complexity of ComfyUI node graphs or A1111’s endless settings panels. It is the easiest way to run local image generation — and it is surprisingly light on hardware.
Minimum GPU: 6GB VRAM. Recommended: 12-16GB. Fooocus runs well on cards that struggle with heavier frontends.

How Fooocus uses your GPU
Fooocus is built by lllyasviel (the ControlNet creator) with an optimized pipeline that reduces VRAM overhead compared to vanilla A1111 or ComfyUI. It pre-loads only what it needs and aggressively offloads unused components.
VRAM requirements by mode:
| Fooocus Mode | VRAM Usage | Minimum GPU |
|---|---|---|
| SD 1.5 (basic) | 4-5 GB | GTX 1060 6GB |
| SDXL (default) | 6-8 GB | RTX 3060 or equivalent |
| SDXL + ControlNet | 8-10 GB | 10GB+ recommended |
| SDXL + multiple styles | 7-9 GB | 8GB+ comfortable |
| Flux via extensions | 10-14 GB | 12GB minimum |
| Inpainting (SDXL) | 8-10 GB | 8GB+ recommended |
The default Fooocus experience uses SDXL models and stays within 6-8 GB of VRAM. This is lighter than ComfyUI running the same models because Fooocus handles memory management internally — you do not need to manually configure tiled VAE or model offloading.
Our top picks
Entry level: RTX 3060 12GB — ~$250 used / from $329 new
The RTX 3060 12GB is the cheapest path to a comfortable Fooocus experience. Its 12GB of VRAM handles SDXL without memory pressure and leaves headroom for ControlNet and style mixing. Generation speed is adequate — expect 15-25 seconds per SDXL image at 1024x1024.
The card also supports Flux through Fooocus extensions using quantized models (NF4/GGUF), though this pushes close to the 12GB limit.

12GB GDDR612GB at $250 used — Fooocus runs SDXL with room for ControlNet.

Sweet spot: RTX 4060 Ti 16GB — $425
This is the GPU we recommend for most Fooocus users. 16GB of VRAM means you never worry about memory limits with SDXL workflows, and Flux via extensions runs at full FP16 precision. Ada Lovelace architecture delivers faster generation than the RTX 3060, with SDXL images completing in 8-12 seconds.
The 16GB buffer also handles multi-ControlNet setups (pose + depth + canny simultaneously) without memory errors — something 8GB cards cannot manage.
Premium: RTX 5070 Ti — $1,050
For users who want fast iteration and zero compromises, the RTX 5070 Ti delivers. Blackwell tensor cores with FP8 support mean SDXL images generate in 4-6 seconds. The 16GB GDDR7 bandwidth makes Flux generation noticeably snappier than GDDR6 cards.
Only worth the premium if you generate hundreds of images per session or use Fooocus as part of a production workflow.

What about 8GB cards?
Cards like the RTX 4060 (8GB) and RTX 3070 (8GB) can run Fooocus with SDXL, but they operate near the memory ceiling. Basic SDXL generation works. Adding ControlNet or style stacking pushes past 8GB and triggers offloading, which slows generation significantly.
8GB is functional but not recommended for Fooocus in 2026. Model sizes keep growing, and extensions add VRAM pressure. Starting with 12GB gives you breathing room.
Fooocus vs ComfyUI vs A1111: GPU needs
| Frontend | Min VRAM (SDXL) | Recommended VRAM | Setup Complexity |
|---|---|---|---|
| Fooocus | 6GB | 12GB | Minimal |
| ComfyUI | 8GB | 12-16GB | Moderate |
| A1111 | 8GB | 12-16GB | Moderate |
| Forge | 6GB | 8-12GB | Minimal |
Fooocus has the lowest VRAM floor of the major frontends. If you are choosing between frontends based on your GPU, Fooocus is the most forgiving option.
Quick decision guide
- Have $250? Used RTX 3060 12GB. SDXL works well, Flux works with quantization.
- Have $425? RTX 4060 Ti 16GB. Best balance of VRAM, speed, and price for Fooocus.
- Have $1,050? RTX 5070 Ti. Overkill for basic Fooocus, justified for high-volume generation.
- Already own an 8GB card? Fooocus will run. Stick with it until you hit memory walls, then upgrade to 16GB.

What is the minimum VRAM to run Fooocus?
Fooocus runs on as little as 6GB of VRAM. Basic SD 1.5 generation uses roughly 4-5GB, and the default SDXL mode stays within roughly 6-8GB thanks to Fooocus’s optimized memory management, which offloads unused components automatically. A GTX 1060 6GB can handle SD 1.5, while an RTX 3060 or equivalent covers standard SDXL generation.
How much GPU VRAM is recommended for Fooocus in 2026?
12-16GB is the recommended range. A 12GB card like the RTX 3060 handles SDXL comfortably with room for ControlNet and style mixing, while 16GB removes memory limits entirely — including multi-ControlNet setups and Flux extensions at full precision. Model sizes keep growing, so starting with 12GB gives you breathing room that 8GB cards lack.
Can Fooocus run on a low-VRAM 8GB card?
Yes, but with limits. 8GB cards like the RTX 4060 or RTX 3070 handle basic SDXL generation, though they operate near the memory ceiling. Adding ControlNet or stacking styles pushes past 8GB and triggers offloading, which slows generation noticeably. 8GB is functional but not recommended in 2026 — plan to move to 12-16GB once you hit memory walls.
How much VRAM does Flux need in Fooocus?
Flux runs through Fooocus extensions and needs roughly 10-14GB of VRAM, with 12GB as a practical minimum. A 12GB card like the RTX 3060 can run Flux using quantized NF4 or GGUF models, though it sits close to the limit. A 16GB card such as the RTX 4060 Ti runs Flux at full FP16 precision without compromises.
