AMD Might Be Working on Z490 Chipset - Would Get More and Faster PCIe Lanes

AMD in recent times have used the prefix "X" in naming their High End Enthusiast Chipset. I don't see them using "Z" and we already know that there's a Z390 in the works from intel.

That's a little confusing, because isn't it X390 (and presumably X490) for Threadripper?
The 400 series motherboards are already underwhelming as-is. Instead of this Z490, they should've just added the extra lanes to the X470.

I like the "Y". I would like the "Y" to get a little love. Y470.... I like it.
It is a bit confusing with the Z.

http://www.guru3d.com/index.php?ct=news&action=file&id=26920 The slide has been doctored. If you simply go up to the header the z490 is listed under Chipset General Purpose PCIe ------>GEN2<------ The Z490 is supposedly gen3 and would have its own slide with its own header not just lumped in with the others as an after thought. Btw Intel is working on a z490 for Coffe Lake so this is where the idea probably came from. Come on you have to do better than this!;) As of May 5th AMD is making a z490 mb but there are no specifics on it's spec's.

i wish PCIE 4.0 would just come out already, what's the hold up?

My assumption has been that we will see PCIE 4.0 on AMD chipsets that come out with the 7nm Zen 2.

Whatever the truth, the issues are simply danced around to confuse folks to the max imo.
Its not a big deal to add lanes in a switched environment like a chipset. Intel have been offering multiple chipset pcie3 nvme ports for ages.
Nowhere do they make clear tho, that in reality, the whole chipset must share the 4GB/s link to the main system (equal to about one nvme) - adding lanes simply shares this 4GB/s among more resources.
If this report is true, as it may well be, then it is not about magically finding 4 more lanes from the am4/ryzen platforms current user total of 24, it is just a chipset mod which allows you to hog the entire chipset bandwidth with one device, which doesnt have to be a bad thing, but they dont make this clear.
To use raid 0 on 2 such nvmeS would be nonsense e.g., but intel give the impression you can, and provide the means for triple raid nvme even on z170 afaik.

not 100% accurate seeing as AMD x300 and x400 chipsets USE PCI-e 3.0 and do have as well PCI-e 2.0, so to claim z490 will use 3.0 because x300/400 only use PCI-e 2.0 is not at all accurate
more lanes would be good though for most people are absolutely not necessary...think If Threadripper (two Ryzen dies) has 64, and EPYC (four Ryzen dies) has 128, so therefore 1 die (Ryzen) is 32 total lanes (at least on a fully enabled chipset such as the high end x370/470 vs x350/x450 type deal, or specific cpu models such as the APU which cut off 8 lanes provided to m.2 or whatever)
(AM4 allows for 24. Eight of those are dedicated to the chipset and an M.2 slot, meaning you effectively have 16 to mess around with in terms of expansion cards (that are dynamically shared or wired electrically by vendors as they see fit)
x370/470 adds another 8 on top of this at 2.0 speeds)
