Hey men, just read your post and checked the single core benchmark. Looks weird indeed that my 10-core Mac Pro 3,0GHz has a better single core speed performance than the new 12-core 3,5GHz Mac Pro. Can't be true.
Only the 28-core performs a tiny bit better while it would have made sense that the other 16/14/12/8 core XEON's would have outperformed it because of their higher clock speeds. The 8-core new Mac Pro didn't fit in the screen print because it's even outperformed by a mid-2017 standard iMac on single core speeds.
Must be sort of a bug, don't you think?
