Better performance on a Mac Pro with more cores or faster CPU?​

I could only find a posting on this topic in the forum from 2012:

Is it still correct that a Mac Pro with a faster CPU will provide Isadora with better performance than a Mac Pro with more cores but a slower CPU speed? ...assuming the GPU, RAM and SSD speeds are the same on both computers?

Specifically, would Isadora work faster with a 3.5GHz 6-core Intel Xeon E5 Mac Pro compared to a  3.0GHz 8-Core Intel Xeon E5 Mac Pro, both using the

Dual AMD FirePro D700?

thank you,
