From Topaz' web site:
"Big Sur and Monterey:
DeNoise AI, Sharpen AI, Gigapixel AI, Mask AI, Adjust AI, and Studio 2 are currently compatible with and supported on Big Sur and Monterey. These apps are not yet M1 native, but will automatically run through your Rosetta 2 emulator if you have are using an M1 device.
Jpeg to Raw AI currently does not function on MacOS Big Sur or Monterey.
Apple Silicon/M1:
M1, M1 Pro and M1 Max chips have been tested with Video Enhance AI, Sharpen AI, DeNoise AI, and Gigapixel AI.
Plugins for DeNoise AI, Sharpen AI and Gigapixel AI are M1 native and will work natively with Photoshop 22.3 and above, which are M1 native Photoshop versions. Our other plugins will not show up on Photoshop 22.3 or higher unless you run Photoshop through Rosetta 2.
To manually force Photoshop to run through Rosetta 2, right-click your Photoshop application icon, select the Get Info menu option, and look for the "Run with Rosetta 2" checkbox in the Get Info panel. If you use the suite of Topaz applications as Photoshop plugins, you will have the smoothest plugin experience on an M1 device by keeping Photoshop running through Rosetta 2 for the time being regardless of which version of Photoshop you are using."

In other words, these people have limited resources or consider the Mac to be a secondary platform. Nearly every other software company in the mainstream imaging business has updated their code for Apple Silicon.

Disk Speed Test. This will allow you to compare your internal SSD speeds with that of all of your attached drives. The M1 series of processors benefits greatly from fast SSD storage connected via Thunderbolt 3, Thunderbolt 4, or USB4. If you're running old spinning platter hard drives, or using slower interfaces, or using USB-C cables meant for USB 3.2 or slower standards, all bets are off.
