@jaymonkeyXeon Workstation/Server class CPU's have many more PCI lanes and thus do not suffer this limitation, that is the primary reason Apple use Xeon CPU's in the Pro products in addition to the high core counts and the ability to use ECC memory.
This has nothing to do with performance, maybe used as an excuse - the higher/more exotic/more proprietary/more difficult to find/more overpriced the hardware, the better the margin for profit. Apple has been using Xeons for other products too (where it shouldn't), it's not the first time. If it was the sheer performance that Apple was after or/and the best benefit for their customers we would have had Power9, EPYC, SMP Xeons etc (or even just a Threadripper).
Regarding the PCI-e lanes, 16x might not be that dramatically better than 8x for rendering or deep learning (not that Apple cares about researchers or scientists) and ECC RAM is mostly used as locking weapon in the Intel ecosystem. If it is about NVME I/O throughput, what will happen when other companies start offering PCIe 4.0 (or is it 5.0?) solutions by the time Apple's new Mac Pro comes out ?
I have never bought Celeron CPUs, they are inferior CPUs for many tasks. I said that I am not making the same comments typical PC users do when they are just bashing Apple instead of Intel too (yet, yes Apple can be blamed indirectly for choosing/locking users to Intel/Xeon).
