I am more curios to what the price differance will be between the boards using the 3 chipsets. Also any infomation on where the chipsets are made and what node?
"As expected, ASMedia designed the X670 chipset, a product of TSMC's 6nm manufacturing process. It's a nice upgrade since X570 was on GlobalFoundries' 14nm process node."
Slot drought - Once upon a time, PC motherboards supported up to 7 expansion slots. Each of the 3 boards pictured above has 3 x16(physical) slots, and the one on the left also appears to have a single x1 slot. I can come up with a number of possible reasons for this. Motherboards come with more included these days. USB is much more capable than in the old days. Big graphics cards hog 2 or 3 slots of physical space. And any extra PCIe lanes are likely to be used for extra M.2 slots, which are very popular.
Aside from liquid nitrogen cooling, can anyone think of a reason why a CPU would need a 20 or 26 phase VRM? Normally, anything beyond 12 (decent phases) is way over built for -- at least if you talk to Buildzoid. I mean for powerdraws through 400w.
When the motherboard already costs over $500 there's no reason not to overbuild the fuck out of the VRM. A couple more bucks in parts and it makes the rich buyer feel all warm and fuzzy inside, and that's what they're really paying for.
It could just be MSI marketing, where the VRM is in fact 12+2, but the 12 is doubled.
What all of these mobos really miss out on, is having a good VRM for the GPU. Like c'mon, I understand mobos for Ryzen 1000 to 5000 having 2 phase VRM for the GPU, since not all of the Ryzen chips had a GPU on them, but that is changing with Ryzen 7000 series. It makes sense to have a decent 3 or 4 phase VRM for the GPU now.

The chipsets are TSMC N6. I don't know about the price difference.CrystalCowboy - Tuesday, May 24, 2022 - link
I could be wrong about that, I might be thinking of the I/O chiplet in the 7000 processors. Am currently hunting for a source.CrystalCowboy - Tuesday, May 24, 2022 - link
Promontory 21 chiplet from ASMedia. Possible involvement by MediaTek at a later date. 7 watts per chiplet. The X670 and X670E will have two of these chiplets, the B650 will have one. No mention of fab.https://www.tomshardware.com/news/amds-multi-chipl...

It says here the chipset is TSMC 6 nm, so I might be accidentally right.https://www.tomshardware.com/news/msi-showcases-am...

Huge upgrade. Won't need an active cooler for the chipset.CrystalCowboy - Tuesday, May 24, 2022 - link

In spite of the excuses, the lack of slots is still a problem for anyone who wants to expand on their PCs capabilities.CrystalCowboy - Tuesday, May 24, 2022 - link
Agreed. I recently had to physically cut down a network card to fit an x1 slot to get the number of ports I required.ballsystemlord - Tuesday, May 24, 2022 - link
