New AMD chipsets surface at USB-IF: A420, Z490 and X499
A handful of new AMD chipset names surfaced in USB-IF registrations. AMD denies that the entries are legitimate, but well the names are in there alright. You will notice a Z490 and X499, which have been rumored about a couple of months ago as well. A420 is also listed, the successor of A320.
The Z490 chipset would enter the race as the new flagship in the middle class, already ready and scheduled for the start of the Computex 2018, but literally, five minutes before the show was still pulled: Too expensive and supposedly too few new features, it was rumored. Additional PCIe lanes would be accomplished with an expensive PLX Chip, which was not available in sufficient quantities, reports computerbase. The same applies to the X499 chipset for the high-end segment. This apparently also was already at Computex 2018 as a refresher for the Threadripper 2000 is considered, the latest rumors now say that he could be unveiled at CES 2019 .
In addition, there is also an A420 chipset as heir to the entry-level model A320. The A320 has not appeared anywhere yet, as have the Pro 460 and Pro 490 solutions - presumably the business offshoot for the Ryzen Pro processor line.
AMD has commented on the topic, and they normally do not talk about unannounced products.
USB-IF certification is a standard procedure for all chipset development, planned early in product development. The USB-IF site was recently updated with AMD test chips which have not been and may not be released. We are working with USB-IF to have these erroneous listings removed from their site.

Using m.2 in sata mode disables the standart sata ports? I've checked several manuals of X470 boards and it only stated that the pcie slot will be disabled if the m.2 will be used in one of them.
I'm asking because I was looking into this recently as I'm planning upgrade and wanted to use m.2 along with standard sata devices. This would force me to use pcie/nvme drives in the m.2 slots if it would be true.
I did a little bit more research and apparently it varies depending on the motherboard. It seems most will sacrifice 2 SATA ports (why 2 instead of just 1, I'm not entirely sure) but it seems there are some that use PCIe lanes too. Generally speaking, it seem that if the M.2 slot uses PCIe 3.0 lanes directly from the CPU, you'll lose 2 SATA ports (and I'm not entirely sure, but I think this is only the case if the M.2 device you installed uses SATA). If the M.2 slot uses the PCIe lanes from the chipset, then you lose those lanes elsewhere.

I guess Intel is going to change the naming convention of the next gen chipsets. Kinda childish of AMD to do this... They don't need to, they have a great product, no one cares what's it called. They only generate more confusion this way.

I agree. I also find it is no coincidence that AMD started out with a number that was 100 higher than Intel's (when AMD released the 300 series chipset, Intel was on their 200 series).

the fantastic news for the biggest slice of the market...if you have an itx system you can ignore the newer chipsets.
that said, as Schmidtbag pointed out mATX and ATX systems with lots of mass storage are the targets.
a mATX with 3 pcie M.2's is choice.
funny thing is that most people are going or have gone to external mass storage, but old habits die hard.

Ideally, yes. X470 is a bit underwhelming for enthusiast grade. They should add another x12 lanes, x8 of which would go to the 2nd PCIe slot and the other x4 for a 2nd M.2 slot. Such a layout could also permit a x8
I think they should also add another 2 SATA hosts, not because the motherboard needs more SATA ports, but because then you don't have to disable them when using M.2.
I personally think that's as good as an AM4 board really needs to get. The current X470 board makes for a great Micro ATX chipset but it's just too underwhelming for full ATX.
