AMD Ryzen 3000: New Block diagram about PCIe 4.0 on Matisse and X570 chipset
Another block diagram of a more official nature leaked, this one holds the X570 chipset breakdown alongside the specs and Ryzen 3000. It's clear already that Ryzen 3000 CPUs (Matisse) and the X570 chipset will support PCIe 4.0. The new diagram once again confirms that the processor will provide a total of 24 PCIe 4.0 lanes.
The new slide breaks down everything related to the IO capabilities of the new AMD platform around Ryzen 3000, it's also a far more official looking block diagram. Now, it can not be completely ruled out that this is a fake, I simply do not expect it to be.
Ryzen 3000 (Codename Matisse) delivers 24 lanes PCIe 4.0
According to a confidential presentation titled " AMD 500-Series Chipset Engineering Interlock " dated May 2019 Ryzen 3000 as CPU (codenamed Matisse) will have a total of 24 PCIe Gen4 lanes. Four of them are used for the interconnect to the X570 chipset, leaving 20 laned Gen 4.0 for other utilization. As expected, 16 lanes (PCIe x16) are intended for graphics cards that are connected as x16 or twice x8 once. One x8 link would offer PCIe 3.0 x16 like bandwidth. Four more PCIe lanes from the CPU are designed for fast storage such as NVMe SSDs. In addition, Ryzen 3000 provides four USB 3.1 Gen 2. A dual-channel memory controller is also no surprise.
When we move to the X570 chipset, the PCIe Gen 4.0 lanes are lines, but not so abundantly clear to follow as everything can be re-routed and shared. For example, PCIe slots, M.2 SSDs, LAN, card readers or WiFi modules are to be connected via the new interface standard. The configuration depends on the respective motherboard.

Please do keep in mind that only Ryzen 3000 (Zen2) will open up X570 to the CPU at PCIe 4.0 x4. If a Ryzen 3000 of the Picasso family, as an APU based on older architecture, are used, the chipset connection will be made with PCIe 3.0. The X570 PCH (Platform Controller Hub) is also credited with an indefinite number of USB ports of USB 3.1 and USB 2.0 and SATA for HDD / SSD.
Numerous X570 motherboards from AMD's partners will be officially unveiled at Computex 2019 next week , no doubt about it. The board partners have been flooding their social networks for weeks with more or less concrete references to the new generation. One detail stands out: All previously unveiled X570 motherboards have a fan for chipset cooling . Whether AMD will officially introduce the Matisse CPUs at Computex remains to be seen. In any case, they will not come onto the market at the end of May, because officially the date is Q3 2019, unofficially July is expected for the market launch.

Afraid you're applying a very limited understanding of the hardware here.
There will be no benefit at all, since gen 3 parts will only be able to communicate at gen 3 speeds and reduced line count would compromise the ransfer rate for older devices.

just to remember the bus between CPU and x570 is x4 4.0 (which is a lot for most of the common users that have 1 or 2 storage devices), everything that's not directly connected with the CPU could be limited if in concurrency with other devices... so all those bandwidth from the chipset you are demanding is simply fancy..

Definitely exist. Example would be the Prime X470-PRO's M.2_2 socket. The reason they do this is to assist PCIe 3.0 x2 drives which are limited to 2 lanes even if the M.2 socket is 4x PCIe 2.0. There's a lot of these: WD SN500, any of the E8/E8T drives, SX6000NP, etc. In that board's case the socket shares a PCIe clock with one PCIe x1 slot and bandwidth with two PCIe slots (these slots share bandwidth with the x4 electrical x16 physical PCIe slot from PCH). I'd say this was an error but I've seen multiple boards as such, like the TUF X470 Plus Gaming, although some of their boards allow x4 PCIe 3.0 by pulling lanes from GPU.
Are there reviews confirming that these M.2 slots actually work in PCIe 3.0 x2 mode, and this is not an error in the specs?

There are few such devices and they are quite slow too, so it would only help synthetic benchmarks.

X570 PCH actually includes 16 (sixteen) PCIe lanes, in addition to the 24 PCIe lanes on the CPU, with a total of 4 (four) 4-lane physical interfaces (4x PCIe 4.0 x4 PHY), fully configurable in PCIE x16, x8, x4, x2, x1, and SATA modes.
The chipset uplink is still PCIe 4.0 x4 though, so the bandwidth would be shared across all devices connected to the PCH lanes.

I didn't say it was a good idea, just that they do it and explaining their reasoning. The point was that you could switch if need be. But a bit of a moot point with regard to this thread as we see the downstream lanes are PCIe 4.0 without any compromises, the B550 might be a bit different of course and the chipset pays by needing a fan. Still, exciting for NVMe fans.

I wonder where does it put the Socket TR4 platform and the upcoming Ryzen Threadripper 3000 processors - since the X570 and the Ryzen 3000 offer 40 PCIe 4.0 lanes in total, allowing full-speed triple SLI and three NVMe SSD slots, the practical applications of the TR4 platform will be limited to a few specific tasks that can scale with additional cores and memory channels, such as 4K video editing, and very high-end systems that require 60+ PCIe lanes for things like quad SLI and NVMe RAID-5...

This was integrated into the chipset, which has a PCIe hub controller anway, and not offered for the CPU lanes (which he was requesting)
I would want my CPU 4x lanes connected directly to a PCIe 4.0 x4 M.2 slot, so that I can run a fast PCIe 4.0 NVMe drive in there in the future. Standalone 6-lane 5-port PCIe switches cost $30-50 per chip, though I agree there is no point to use them to downconvert CPU lines and lose full PCIe 4.0 x4 bandwidth.
PCI-E3 parts will benefit from gen 4 controllers in ways just gen 2 parts benefitted from gen 3 controllers.
being able to reduce the lane count for nvme's and not losing performance is a reason why. There will be no benefit at all, since gen 3 parts will only be able to communicate at gen 3 speeds and reduced line count would compromise the ransfer rate for older devices.
Many existing boards switch 4x PCIe 2.0 into 2x PCIe 3.0 for M.2, for exampleAre there reviews confirming that these M.2 slots actually work in PCIe 3.0 x2 mode, and this is not an error in the specs?
Theoretically they could bypass the PCH and directly connect the secont M.2 slot to the CPU, but the only benefit would be slightly higher peak bandwidth from using 128b/130b encoding. There would be absolutely no benefits for upconverting PCIe 2.0 x4 from the PCH into PCIe 3.0 x2.
