Minimal Hardware Requirement

Minimal Requirement

Below is the minimal requirement for running Fooocus locally. If your device capability is lower than this spec, you may not be able to use Fooocus locally. (Please let us know, in any case, if your device capability is lower but Fooocus still works.)

Operating System	GPU	Minimal GPU Memory	Minimal System Memory	System Swap	Note
Windows/Linux	Nvidia RTX 4XXX	4GB	8GB	Required	fastest
Windows/Linux	Nvidia RTX 3XXX	4GB	8GB	Required	usually faster than RTX 2XXX
Windows/Linux	Nvidia RTX 2XXX	4GB	8GB	Required	usually faster than GTX 1XXX
Windows/Linux	Nvidia GTX 1XXX	8GB (* 6GB uncertain)	8GB	Required	only marginally faster than CPU
Windows/Linux	Nvidia GTX 9XX	8GB	8GB	Required	faster or slower than CPU
Windows/Linux	Nvidia GTX < 9XX	Not supported	/	/	/
Windows	AMD GPU	8GB (updated 2023 Dec 30)	8GB	Required	via DirectML (* ROCm is on hold), about 3x slower than Nvidia RTX 3XXX
Linux	AMD GPU	8GB	8GB	Required	via ROCm, about 1.5x slower than Nvidia RTX 3XXX
Mac	M1/M2 MPS	Shared	Shared	Shared	about 9x slower than Nvidia RTX 3XXX
Windows/Linux/Mac	only use CPU	0GB	32GB	Required	about 17x slower than Nvidia RTX 3XXX

* AMD GPU ROCm (on hold): The AMD is still working on supporting ROCm on Windows.

* Nvidia GTX 1XXX 6GB uncertain: Some people report 6GB success on GTX 10XX, but some other people report failure cases.

Note that Fooocus is only for extremely high quality image generating. We will not support smaller models to reduce the requirement and sacrifice result quality.
