That's what I said?Not quite. SSDs were saturating the SATAIII bandwidth available. SSDs now connect through an NVME slot that take over 2-3 SATA ports and combine that bandwidth. PCIe SSDs bypass that altogether. It's why the Corsair PCIe4 SSD can outperform the fastest Samsung NVME. Ironically, some boards with NVME SSDs will shutdown PCIe lanes and not ports.

From the apple site:I think the real problem with getting AMD is that they do not support thunderbolt and apple is all in on thunderbolt. Which means they are left with Intel's laggy chip designs. And Intel Xeon chipsets are stuck on PCI3. At this rate, it might be 2 years before Intel gets a PCI5 chipset out for Xeons, and then there is a decent chance apple will lag a year behind that (assuming they even update the nCMP regularly--an unknown right now). So my guess is, it could be as bad as 3 years to get PCI5 on a mac pro.
Hope I'm wrong. Please someone convince me I'm wrong.
Each MPX bay provides:
x16 gen 3 bandwidth for graphics
x8 gen 3 bandwidth for Thunderbolt
DisplayPort video routing
Up to 500W power for an MPX Module
Alternatively, each MPX bay can support:
One full-length, double-wide x16 gen 3 slot and one full-length, double-wide x8 gen 3 slot (MPX bay 1)
Or two full-length, double-wide x16 gen 3 slots (MPX bay 2)
Up to 300W auxiliary power via two 8-pin connectors
==========
We'll have to wait till intel supports newer PCIe gens which could take a while
