Received a Mac mini M4 Pro with 14‑Core CPU, 20‑Core GPU and 24 GB RAM today. My idea was to replace my Mac Studio with M1 Mac with 10-Core CPU, 24-Core GPU and 32 GB of RAM.
In normal use the Mac mini is not hearable and quieter than my Mac Studio.
I tested both with the KI denoising tool of Camara RAW in Photoshop 2025. To test the devices some time under full GPU load I choose 50 Nikon Z6II RAW files for denoising.
Mac Studio needed 13 minutes and 15 seconds, without spinning the fans higher as in idl.
Mac mini in automatic mode needed 13 minutes and 45 seconds. After around 1 minute of denoising, the fans start to spin faster and faster and get clearly hearable. It sounds a little bit like a small vacuum cleaner. Recorded a small Video with the sound.
Mac mini in low power mode needed 24 minutes and 45 seconds, but the fans did not start spinning faster.
So I will stay with my Mac Studio M1 Max and maybe get a Mac Studio M4 Max next year.
