Short description of error
This is not a bug report, rather an information update to the issue #112596. I hope it's okay to file a report for that.

I had random crashes on my intel 27" iMac from 2020 with 128 GB memory with applications like blender, PTGui, Nuke, CaptureOne, etc. and I filed a report that the workshop blender benchmark scene was getting slower and slower.

In the end I gave the iMac to Apple to check the machine, first the 3rd party RAM was blamed but in the end Apple changed the logic board (mainboard with CPU and GPU) and I restored my system.

Completely unexpected the workshop blender scene came back to the old render speed that I had earlier this year.
For the moment it seems like my faulty hardware significantly reduced the render speed and that was the reason why I filed the bug report in the first place. I hope this might help to understand the original issue that I had.

Best regards
Daniel

Hi, thanks for the report. As far as I understand, this bug report is to notify us about the "fixed render time". Good to know in case problem is fixed and to let us know the cause behind it. Richard was able to repro #112596 so it's strange that problem is fixed after system check from Apple team.
Closing anyways.
