It's not true. PCIe has been replaced by Thunderbolt 2 in Mac Pro 6.1. Unfortunately, it was not a good idea.Wow thanks for the totally unneeded graph. I understand PCI-E x16 is far faster then TB3 if it wasn't TB3 PCI-E add-on card would not function in a x4 slot. And the Mac Pro 6,1 was not a system designed with the ability to added PCI-E devices so logically it was not crippled. Designed inferior to the Mac Pro 5,1 yes but not crippled.
Besides, few people realize that Thunderbolt 3 has only theoretically 40Gbit bandwidth. In fact, these 40Gbit are divided into DATA and Video. Which gives us max. 22Gbit to DATA. Which is less than PCIe x4.
