AMD X570 chipset gets PCI Express 4.0 and USB 3.1 gen2
As we get closer to the Computex announcements with hopefully some good NAVI and Ryzen 3000 info, we all klnow there will be a new chipset from AMD as well. It's not likely to be a massive upgrade chipset as the procs mostly are backward compatible with X370/X470.
According to new sources (which always need a disclaimer and a few grains of salt), the new generation of AMD Seriers 500 motherboards would, however, have a number of differences: the B550 chipset would not support PCIe 4.0, which would be exclusive to X570 boards.
- USB 3.2 Gen 1: originally known as USB 3.0, and previously renamed to USB 3.1 Gen 1. It’s the original USB 3.0 specification, and it can transfer data at up to 5Gbps.
- USB 3.2 Gen 2: Previously known as USB 3.1, and then later as USB 3.1 Gen 2. It offers speeds at up to 10Gbps.
- USB 3.2 Gen 2x2: formally known as USB 3.2, it’s the newest and fastest spec, promising speeds at up to 20Gbps (by using two lanes of 10Gbps at once).
The X570 chipset would have 40 PCIe lanes, although some of those lanes would have been shared with the SATA interface. These boards would allow for eight USB 3.1 gen2 ports (10 Gbps), in addition to four USB 2.0 connections (but not USB 3.2 Gen2 )
X570
The third generation of Ryzen processors would not be compatible with the A320 chipset, although it is claimed that there are practically no differences between B350 and A320. The X570 boards should be on the shelves from July, with B550 arriving two months later.

True, but thats what Threadrippr platform is for (64 lanes).
Even the 2080ti wouldnt come close to saturating 8xPCIe 4 let alone 16. PCIe switches are a perfectly good soloution for most uses too and splitting multi GPU to 8x8 is perfectly good for very much for the lifespan of this chipset.
Not complaining though, more the merrier!

Does a 2080ti saturate a x8 PCIe 3? i know it didn't with a 1080ti, PCIe 4 either way should be nice specially if systems only allow say x16 overall, means having x4 or x8 or something won't matter as much.

NVME SSD perhaps and additions of more M.2 ports and the like, no need for splitting the bandwidth or lanes or other workarounds though even in this mode it seems to be capable of delivering around 1 to 1.5 GB/s of data which should be plenty for most activities.
GPU I doubt would be a problem, maybe multi-GPU but yeah the driver situation and low-level API support situation for those are less than ideal currently though it's not quite dead either.
EDIT: But yeah 8x is probably not really much of a drop if any even with PCIE 3.0 currently if using multiple cards.
(And even then I think newer motherboards and processors can still do 16x and 16x for dual GPU configurations and then it splits to 8x and 4x though it likely depends on hardware used.)
Though I am quite behind on the subject of these newer fancier devices and standards for now so yeah, lots of reading ahead I suspect for when the next time to upgrade is actually going to be a thing.

Not saying i disagree, i'm just pointing out that part of what is wrong with the article, or what is wrong with what you are saying, is this part:
"These boards would allow for eight USB 3.1 gen2 ports (10 Gbps), in addition to four USB 2.0 connections (but not USB 3.2 Gen2 )"
So, either USB 3.1 Gen 2 and USB 3.2 Gen 2 are different, or the article is not exactly...formatted correctly, or... has a mistake.
According to the information i have been able to figure out
USB 3, 3.1 Gen 1 and USB 3.2 Gen 1×1 are all the same
USB 3.2 Gen 1×2 is new to USB 3.2
USB 3.1 Gen 2 and USB 3.2 Gen 2×1 are the same
USB 3.2 Gen 2×2 in new to USB 3.2
So USB 3.2 Gen 2, isn't necessarily the same thing as 3.1 Gen 2, if by USB 3.2 Gen 2 you mean Gen 2×2
This chipset APPEARS to not have USB 3.2 Gen 1×2 or USB 3.2 Gen 2×2, so effectively, no USB 3.2
3.1 Gen2 and 3.2 Gen2 are the same thing.

40 lanes of PCIe is just about perfect. many gamers forget about content creation and super high speed memory, given the number of cores this is about just right when you factor in pcie drives, gpu's, and M.2's.
DDR5 would have been a nice touch (esp with up to 256 Gb), but the folks at AMD do not want to waste the hard earned goodwill of the consumers with too many incompatible mobos. a la Intel.
