MSI MEG X670E Godlike PCB Layout Leaks, Being Teased in the PRC
In a couple of days, AMD will be co-hosting its Meet the Experts event with several Taiwanese motherboard makers, which are said to be showing off their upcoming X670/X670E motherboards during the event. However, courtesy of multiple sources, we already have a preview of MSI's upcoming MEG X670E Godlike motherboard. MSI itself has posted a teaser on bilibili in the PRC, which shows off the four M.2 slots the board will have, of which three supports the new-ish, slightly wider 25 mm M.2 form factor, compared to the more common 22 mm width for M.2 drives. Note that MSI writes that all four M.2 slots are PCIe 5.0, but it appears that only one of the slots is actually PCIe 5.0, with the other three being PCIe 4.0. Courtesy of Wccftech, we also have the PCB layout and Videocardz got their hands on most of the specs for the board.
The PCB layout was also annotated by @harukaze5719 to make it easier to see what some of the parts are. The board will apparently have a 24+2+1 power phase layout. It also has two additional power inputs via standard 6-pin PCIe type connectors, one for USB-PD and one that provides extra power for the PCIe slots. The board has a total of three PCIe 5.0 slots, with the first two slots sharing bandwidth and the third slot being a x4 slot that is also connected to the CPU. The board will also have eight SATA ports, two internal USB-C ports, as well as a rear one and a pair of modules around the back of which at least one should be WiFi. The board also has two Ethernet ports, one 10 Gbps and one 2.5 Gbps, at least five USB-A ports, nine fan/pump headers, a POST80 debug LED display and space for some overclocking friendly features. The 24-pin ATX power connector appears to be right-angled. Expect this to be a very premium product price wise, most likely well north of US$800.

Where can I find a quality mobo, with no Wi-Fi (Wtf do you need an ultra expensive wifi for a desktop?? there are a lot of cheap USB Wi-Fi dongles out there if needed), 4xPCI-E slots (this garbage has only 3??);
1x2.5Gbps LAN is perfect, 2xM.2 slots are more than enough, and that's it?
Think i would rather buy the Carbon or the Ace and a SilverStone ECS07 might be a worse solution but its cheaper
You'll never get as good WiFi signal with the USB dongles as you will with these cards and proper antennas.That's not how that normally works. This isn't a new feature either.I very much doubt that.
it seems, this MB should not be so costly, after all.
2nd screenshot:
( Google-Search show lately often false results, eg. very low prices, and then when you click on it, it is either not available, or with much higher price)
It should be cheaper than the current board, since the 10 Gbps chip is onboard, rather than as an add-in card.
I guess it'll depend on the bundle.
I hope others configure their board better and offer one x16 Gen5 and 2 or 3 Gen5 M.2 slots.
but the fact there is only 1 x16 slot is a little meh cause the 2nd one could be used for something like this
www.asus.com/uk/Motherboards-Components/Motherboards/Accessories/HYPER-M-2-X16-GEN-4-CARD/
Count with me:
The Ryzen 7000 series has 28 lanes PCIe gen5. 4 of these are downlink for the chipset.
Now you have 2x PCIe gen5 x16 slots with 16x/0x or 8x/8x configuration. That's 16x overall.
What is left is PCIe gen5 x4 which is the third "x16" PCIe slot and x4 for the gen5 NVMe. The rest has to come from the chipset.
Now the chipset has 2x x4 PCIe gen4 but on the first chipset x4 is used as downlink for the second chipset (daisy-chain). So you have total 3x x4 PCIe gen4 from both chipsets. Which are the 3 NVMe slots.
In addition to that you have 2x x4 either PCIe gen3 or SATA.
You need x1 for the WiFi, x1 for the 2.5gbe and x2 for the 10gbe (which is not quite enough but near). That's x4 PCIe gen3 lanes.
So you are left with x4 PCIe gen3 or SATA.
So how do you get 8x SATA?
Either you will have to multiplex 4x SATA with one NVMe (which means you can use either one but not both at the same time).
Or you can take those x4 PCIe gen3 and put SATA controllers there.
There are controllers which take x2 PCIe gen3 and have 4-6 SATA ports.
So let's assume you use 2x x2 PCIe gen3 with two such controllers and get 2x 4x SATA ports which are those 8x SATA.
2x PCIe gen3 x2 is roughly 2000MB/s badnwidth (actually less, but let's simplify).
So you have to divide this bandwidth for 4x SATA drives.
That makes 500MB/s per SATA port theoretically. Practically you can be happy if it reaches 400-430 MB/s. Significantly less than what SATA is capable of (if you use all 4 at the same time).
So this is why the other boards don't do it...
[EDIT: I forgot the PCIe gen5 NVMe]
Show me another motherboard which has that.Not, if you use RAID .You cannot have x16 gen5 PCIe plus 3 Gen5 M.2 slots (plus X670 chipsets) with Raphael 7000.
That would be 32 PCIe lanes from the CPU but it only has 28 lanes...No, if the first slot is x16, the second one is x0. If the second one is x8, the first one is also x8. (x16x0 / x8x8 configuration).
If you would have two x16 slots with each x16 PCIe lanes, it would mean 32 lanes for just the first two PCIE x16 (mechanical) slots.
But you need also x4 for the first NVMe and x4 for the downlink to the chipset. That would be 40 PCIe gen5 lanes all together.
The CPU has 28 PCIe gen5 lanes, however...
It's just IMPOSSIBLE. It's a simple math...
Wait! Dual chipset?
Can someone explain to me if intel has a dual chipset? - No right? - Intel use to have NB & SB design
This is 1st AMD MB with dual PCH or previously also AMD had?
