Question

How much do graphics cards speed up new AI tools? Could Adobe provide this data?

I had a new computer built for me a few years ago.  At that time there were no graphics cards available thanks to crypto currency miners. Lightroom ran great for me without the graphics card at the time. Now with the new AI tools "denoise" is taking me 17 minutes to run. I obviously need a graphics card, but can't find anyone who has tested different cards to try and help me understand how much this could reduce my processing time.

 

It would be great if Adobe could test the same image on the same computer with a couple options (e.g., no graphics card, 4060 card, and 4080 card) and show how much time this could reduce. This could help folks in the future know how much to invest to speed up the Adobe tools.  I am buying a 4060 card and hoping for the best.

It woulkd be nice if there was an option to just use the cpu, I bought a new Intel NUC13 with I7 processor and 32gb memory and it takes 12 minutes with the gpu at 100% and the cpu at 1%. You can turn off the gpu in preferences but denoise still uses it.

That's not going to happen as AI uses GPU and other extensions to same such as NVIDIAs Tensor cores and Apple Neural Engine.

Turning Off the GPU has no affect the operation of the GPU. AI uses the GPU whether its enabled or disabled using the preference.
