A1111 Stable Diffusion speed?

I am playing a bit with Automatic1111 Stable Diffusion. At the moment, A1111 is running on M1 Mac Mini under Big Sur.

The performance is not very good.

A picture with sees settings need around 5 min. 47 sec. (10.86s/it). My Mac Pro with Windows and an old Titan X give me a picture every 40 seconds.

It looks like GPU and Neural Engine are not working. Did I get a better speed when using a newer system?

Start setting are: ./webui.sh --skip-torch-cuda-test --precision full --no-half --medvram --opt-sub-quad-attention

A short feedback...

Same stable Automatic1111 Stable Diffusion with same settings.
I have updated the System to Ventura and now I get better results

Big Sur, Standard A1111: 5 min. 47 sec. (10.86s/it)
Ventura, Standard A1111: 1 min. 40 sec. (3.14s/it)

Ventura, Standard A1111: Slartibarts link 1 min. 19 sec. (2.64s/it)

Looks like the neural engine is not in use, only the GPU.

That's pretty dang slow. Have you tried Draw Things from the app store? Although I suppose Draw Things also uses similar back end

What is your system and how long do you need?

EDIT: Draw Things needs 1:42 under Monterey

This is the MPS optimization from Ventura. Monterey is a little bit slower. My personal problem is, that my Mac Pro from 2008 with a old Titan X Maxwell is up 2 to 3 times faster, My 2010 Mac Pro with Vega Frontier is at nearly the same speed as the M1 Under Windows. Im sure the 5,1 is faster under MacOS (Tests with my Mac Pro 2013), but I don’t have OpenCore on it.

Exactly values coming, when back to my room.

Yeah SD on Silicon is way behind PCs with discrete GPUs, even older Macs with older GPUs, let alone anything like a 4070.

over 20 mins, make a test when I have the time

That doesn't look to bad. The Titan X is a dedicated GPU with a 250 TDP running CUDA code that has been optimized over the arc of a decade. The M1 GPU is what, 15 Watt?

This is a GPU from 2015 with 28nm, so it looks not so nice.
 
I have added my Mac Pro 2010 who is also faster than my M1. On my 6,1 I can't finish the picture under Windows, because I got a low VRAM error.

Is here anyone with a Rx 5700 or newer on a Intel Mac, who can run automatic 1111? Hope to see results of newer GPUs.
