It’s supposed to be tuned more toward heavy workflows, such as rendering and CAD. It has support for more RAM (6TB) and quad SMP along with ReFS, and SMB Direct.
I only found out about it because we needed a beastly set up for combining lidar and drone aerials in Autodesk.
Is there some reason to think that running Windows 11 Pro for Workstations would have made a difference in a CPU benchmark? I'm not seeing anything obvious on the feature list for that version that would make that be the case.
