Unannounced AMD 400-Series Chipset Appears In PCI-SIG Integrators List

[It's me!]

Well well, so it begins. AMD has 400 Series motherboards listed on PCI-SIG  Integrators list. Woot! I bet they stick with Socket 1331 too, so perhaps just a bios flash to move  forward. 

 

One thing is for certain, whatever they have is coming soon!

AMD announced earlier this year that it would switch from 14nm LPP to GlobalFoundries' 12nm LP process, so naturally, we expect it to have new processors in 2018. And indeed, AMD has a new AMD 400 Series Chipset listing on the PCI-SIG site. (The PCI-SIG Compliance Program tests products and ensures interoperability with the PCIe interface.)

I'm not sure why Tom's would call it that. It's kind of been known for a while and this isn't an announcement.

What did Tom's call it? I think it is the 400 series. Seems odd to call the chips Pinnacle tho, isn't that the name of the new APUs?

New CPU-s in Q1, so makes sense that new mobos are coming aswell.

[It's me!]

Well, the listing does tell us that 1.) it will come with PCIe 3.0 and 2.) that it will not come with PCIe 4.0, which is a bummer. 

[NumLock21]

Finally to PCIe 3.0!

Can you feel it?  Cause I can feel it in my body.

One would expect Ryzen chipset to support Gen3, but it's doesn't, which is a odd move from them.

Welcome to 2014, AMD

 

I'm guessing they couldn't achieve 4-lane 3.0 spec, so spreading out to a 8-lane 2.0 spec had to do

They release Ryzen so late into the game, where they can easily implement Gen 3 and yet they still choose Gen 2. Dafuq is wrong with them?

its on the chipset side.

Ask ASMedia? o_o

 

Why ask AsMedia?

AMD X370 runs at Gen 2 not Gen 3.

There doesn't appear to be any PCIe 4.0 devices in the pipelines until at least H2 2018 that would touch the consumer segment.

 

Icelake & Zen2 will both, more than likely, have PCIe 4.0 lanes.

you cant even saturate a PCIE 3.0 X16 anyway why would you care?

 

PS: What is this, people are saying? Ryzen has PCIE 3.0 or are we talking about the secondary/third slots?

[paddy-stone]

Personally, I don't give a shit what the secondary and lower PCI-e slots gen are, most people would only use the main slot and secondary at most, and pci-e 2.0 is still enough for todays GPUs IIRC?

 

Is there anything currently on the market that could over-saturate a pci-e 2.0 x16 lanes?

Because the chipset is made by ASMedia. Ryzen is a SoC. The majority of IP blocks are on-die. However they implement a discrete chipset for extended functionality. That's what runs PCI-E 2.0 which is probably due to bandwidth limitations. The PCI-E lanes from Ryzen itself are PCI-E 3.0.

I would like AMD to take things back in-house but it's cheaper to buy than to develop.

It might mean that now there are more lanes left for more important things like dual nvme directly from the cpu 

but according to all the diagrams i have seen, ryzen cpu is only providing 24 lanes but we know its capable of 32 and i would like to have those unlocked 

@leadeater @Taf the Ghost do you guys think we might see those lanes unlocked?

[Doobeedoo]

Great, refinements to platform while keeping AM4 cause no actual reason phasing it until actual next big next gen.

If I remember right, it's actually an AM4 limit. More simple designs, less traces on the motherboard.

 

Also, it's 4x PCIe 3.0 to the PCH. The 2.0 version appears to be their reference for testing the original Zen designs.

Yes, AMD have said that they're keeping AM4 until whatever's after Zen 3.

 A lot of users waited extremely long time to get Ryzen and once they got it. They soon found out the chipset is actually gen 2, while Intel is at gen 3, boy they must be disappointed. x370 was release early of this year, to have X470 release early next year, then X370 is chipset with the shortest lifespan.

Ryzen is 3.0, Chipset is 2.0, but the communication between Ryzen and Chipset is also 3.0. The way I see it is, they took way too long to release it, so by the time it did, the chipset is already consider outdated, when Intel already have chipset running at 3.0. If they released Ryzen back 3 years ago, okay then fine, cause Z97 and X99 were also running at 2.0.

Asmedia, okay I see why, all it does it just handles the SATA, USB, and Asmedia does make SATA and USB controllers. Looks like those 8 gen 2 lanes were slapped on the very last minute. With AMD taking this long to release Ryzen, they should have developed the chipset themselves, instead of relying on a 3rd party like Asmedia.

Should be, aren't the 400 chipsets supposed to be giving PCIe 3.0 off the chipset now? Only way I see that happening is if all the lanes are in use now.

From my understanding it was a design choice to use PCIe 2.0 from the chipset, they are using the chipset to double the lane count so they can have more devices connected to it. 4 lanes isn't enough and a single NVMe would use that so you'd have nothing left for things like audio or lan or wifi or w/e else needs connecting off the chipset. Might be wrong on some of those as some might come of the CPU since it's more an SoC but the point is it was by choice not by mistake or lateness, PCIe 3.0 was around long before the chipset was even being designed.

PCI-E 3.0 was mainstream at the time so I don't buy that it was development hell causing it to be 2.0. I'm guessing it was cheaper, simpler to implement. Probably also to do with lane splitting. They'd probably end up halving the lanes if it was PCI-E 3.0 with the current design. I'm thinking it's a combination of ASMedia chip design being pretty bad and AMD cheaping out on both motherboard design (simpler traces) and PCI-E lanes to chipset.

 

I'm assuming AM4 and motherboard designs weren't started in 2012/13 so it was probably planned that it was the best compromise with the resources at hand. AMD needs to up the lanes on-die either way but I don't think they'll do that with Pinnacle Ridge though.

The only way to saturate PCIe 3.0 x8 on the consumer market apart from storage is to run dual Titan Vs. Presumably the V100s do as well on the enterprise market.
