Factory Drawing of ASUS X670 Prime-P WiFi Appears Online

We're expecting to see a wide range of AM5 motherboards next week during Computex, but we're already being treated to some early leaks ahead of the show. The most recent leak was picked up by @9550pro on Twitter, but was originally posted on Baidu. What we're looking at here though, isn't actually a picture of a motherboard, but rather the placement map for the SMD components used during motherboard assembly. These pictures are often used to make sure things like the solder mask and components were applied properly during production. However, it does give us a good look at the overall layout of the ASUS X670 Prime-P WiFi and the fact that the X670 chipset does indeed consist of two parts. What is also clear is that we're looking at a PCIe 5.0 x16 slot here, as these slots are SMD components rather than through hole.

Other things that are clearly visible, includes support for three M.2 slots, of which the one closest to the CPU might be PCIe 5.0, but there's really no way of telling by just looking at the connector placement. There's also a space for a WiFi module at the bottom of the rear I/O, but beyond that, it's hard to make out the proper port layout. However, there appears to be at least one USB-C port at the rear, as well as a header for another one at the front of the motherboard, next to a USB 3.0 header. The board also appears to feature 14 power phases and obviously four DDR5 DIMM slots. The chip between the two chipsets are either a Super I/O chip or possibly a PCIe redriver. In addition to the x16 PCIe 5.0 slot, the X670 Prime-P appears to be getting a single PCIe x1 slot and two PCIe x4 slots, both which appear to get physical x16 slots. Finally the board should have two SATA ports mounted at a 90-degree angle, as well as four ports at the bottom edge of the PCB. ASUS seems to have gone for a solar system pattern on the PCB itself, so it'll be interesting to see what the actual boards will look like.

Prime and again killed SLI and CF . Maybe it's a PLX chip and it will be possible to build a RAID 0 with M.2 , on additional pci 4 exp slots, but it is also possible that the same board will carry different options of motherboards .

Why would they put a PLX on entry level board, if it was Crosshair formula or Apex or Extreme it was understandable.

PLX chips are BGA type chips, so that a big fat no based on the solder pads for that chip.

Why two chipset chips? does AM5 require two

Require, no.
AMD went for a different approach this time around, where B650 gets one chipset and X670/X7670E gets two chipsets, that are the same chips as what B650 uses.
In other words, X670/X670E should offer twice the connectivity over B650.
I don't have the specifics of what connectivity a single chipset offers though, but it looks like at last eight PCIe 4.0 lanes, some USB 3.x ports, as well as SATA support and the usual kind of chipset interfaces.
It's possible we'll see AMD going down the same route as Intel and add some PCIe 3.0 lanes as well, for things like Ethernet, WiFi and so on. It would be more power efficient if nothing else.

Two chips is extremely kludgy because it means two cooling solutions and less board real-estate available for connectivity. On the upside, you won't need an active fan to cool them. They'll have to put out a massive number of PCIe lanes to justify this.

LOL. You will never see a PLX chip on a motherboard again, that company figured that they could make far more selling to enterprise.

Also a lot more cost effective. Placement will differ from board to board.

Well, they were also bought, up a couple of times, so they're no longer around. Plenty other companies now that make similar products though.

I've never seen one of these before. Very interesting. Thank you for the Saturday news post, it goes well with my coffee.
:toast:
Quick question, any idea what is the square placement between the two supposed chipsets and the first pcie x16 and 2nd m.2 slot? Maybe location of the CMOS battery?

As I wrote in the article, most likely the Super I/O chip or possibly a PCIe redriver.

Whoops. I missed that. Still waking up. I think I need coffee IV lol. Thanks.
Are redrivers becoming more prevalent due to the newer pcie versions?

Possibly, depends on multiple factors.
Retimers are on the other hand no longer approved by the PCI-SIG, which suggests an uptick in the use of redrivers regardless.

TheLostSwede@DeathtoGnomes is this news then?
I wanna say it' snot, but I'd have to hand you a tissue too. As it is, I can only ask....Does it come with OARS? Unconfirmed leaks are made fun of to take the seriousness out of them if they prove to be misleading or false. IDK how many times we are told to take them with a grain of salt, which muddies the line between news and PR stunt. The real question is, is this worthy of being on the TPU front page, afterall TPU doesnt have a 'third page' news page (not worthy of front page but newsworthy none the less).

Thanks for asking. :love:

I have done raid 0 using 3X nvme on x470, using a Asus hyperX16 adapter though.
Yes though your right could be good.

Well, I can tell you that this is the real deal. I sit on enough information about what AMD has coming next week, to know this isn't fake. Having been involved in the development of several products, I also know that this is the kind of thing that's used in the factories where the motherboards are made.
A lot of people don't understand what this is and have called it fake over at other publications, but I can assure you it's not.

Its a planning tool, I get that. Its hard to write straight on paper if the lines to guide you are not there. The fact that this specific item was leaked is unusual, its nice that it doesnt come with the usual PR fodder.

That's because engineers that leak things like this and are caught, get sacked. Although maybe not in the PRC, as apparently it's exceedingly difficult to fire someone there.

I dont believe all leaks are like that, but it is hard to distinguish if its a PR gimmick or actually from some engineer. Pass the salt. :D

So wait, a PCIe 5.0 x16 slot is held on only by the brittle, lead-free solder?

Even the old through-hole design needs reinforcement with today's chonktastic GPUs!

They still add those reinforcement brackets over the slots, but yes, PCIe 5.0 slots are SMT mounted, although if you look carefully, there are some anchor points as well.
The same applies on Intel boards. Have you heard about any slots being torn off Z690 boards?

I'm pretty sure plenty of Z690 boards already have a SMT PCIe 5.0 slot. Reinforced and whatnot as per usual, haven't seen any fall off yet.

I won't be surprised if it turns out that X670 systems have the ability to be split in two almost independent PCs, each using one CCD, one half of the I/O die (or one of two I/O dice?), one channel of RAM, and one half-chipset.

Hah! Not yet, but if UPS/Fedex can rip a dual-slot GPU out of a PCIe 4.0 slot, I'm wondering if there's excitingly-destructive shenanigans to come as we see more Z690 prebuilts!
