Best Speed Benchmarking Tool for Photoshop CC 2020 on Mac

Does anybody know what the best benchmarking tool for Photoshop CC 2020 on a Mac is? I tried Puget systems but then once it provided a score lower than expected for the system I'm running, I realized it was actually developed using Photoshop CC 2019 (and using Windows), which is known to have been faster than the current 2020 version that many users are reporting is much slower across the board, independent of the machine.  It feels like my Late 2015 iMac desktop with lower specs is operating the program faster than my maxed out brand new Macbook Pro 16" with double the ram (64GB). Thanks!
