MPG tested the Apple 16.2" MacBook Pro with M1 Max Chip Z14X000HR, a maxed-out model in all ways except 4TB SSD instead of the maximum 8TB SSD.
This set of tests with these Photoshop filters offers a general look at what kind of performance can be expected with commonly-used filters.

The 2021 MacBook Pro M1 Max wins on every filter, so long as OpenCL is enabled.
Some filters are slightly faster witih OpenCL off, but Sharpen is hugely slower with OpenCL off. So much so that OpenCL should be left enabled.
Except that there is a nasty bug in Smart Sharpen that makes it unusable with OpenCL.
The slow Sharpen performance with OpenCL off turns shows a performance bug in Photoshop in that it is using only a single CPU core on the MBP M1 Max, versus multiple CPU cores on the Intel-based Macs. Indeed, running Photoshop in emulation as an Intel app on the MBP, the time is 3.2X faster in emulation than with native code, because most of the CPU cores get used.
As per Adobe engineering, Jan 2022:
Everything written in OpenCL is being rewritten for Metal on macOS this year. OpenCL and OpenGL are dead. I believe SmartSharpen is at the top of the list to move to Metal off of OpenCL.
