Intel H670, B660, and H610 Chipset Features Leaked
Intel is preparing to significantly expand its 12th Gen Core "Alder Lake" desktop processor series next January, alongside more motherboard chipset choices for the client-desktop segment. These include the H670, the B660, and the H610. The H670 offers most of the I/O features of the top Z690 chipset, but you lose out on CPU overclocking. The B660 is the mid-tier option, and while you still get a formidable I/O feature-set, the chipset bus is narrower. The H610 is the entry-level chipset with very basic I/O, and no CPU-attached NVMe slots. The interesting thing is that all these chipsets support PCI-Express 5.0 x16 (PEG) from the CPU, but leave it to the motherboard vendors whether they want to implement it. There do exist Z690 motherboard that lack Gen 5 PEG (and only feature Gen 4).
The chipset-attached downstream PCIe also varies greatly across the lineup. The top Z690 part puts out 12 Gen 4 lanes besides 16 Gen 3 lanes; while the H670 puts out 12 each of Gen 4 and Gen 3. The B660 puts out 6 Gen 4 lanes and 8 Gen 3 lanes. The H610 completely lacks downstream Gen 4, and only puts out 8 Gen 3 lanes. The H670 and B660 put out up to two 20 Gbps USB 3.2 Gen 2x2 ports; while the H610 lacks 20 Gbps ports. All chipset models put out at least two 10 Gbps Gen 2x1 ports; and at least four 5 Gbps Gen 1x1 ports. An interesting aspect of the lineup is that Intel is allowing memory overclocking across H670 and B660 chipsets, provided the CPU supports it.

wow the've cut some things far back
You want Premium Intel? Get a Z690. You want cheap Intel? Get a B460 + i5-10400F / i7-10700F on clearance. Increasingly expensive but increasingly crippled B boards (SATA also dropped from 6 to 4 I see) make zero sense for a "money saving" platform.
It's Z690 if you want everything or B660 for a balanced option that looks to be more than enough for non K-series chips.

even AMD A520/A320 support NVMe PCIe 3.0 x4 but H610 doesn't ? What's that?
Edit : I checked Asrock H410/H510

they support NVMe but through Chipset?
Intel has a bizarre cost structure for its chipsets.
Also, that $18 is $50 by the time you buy the board.
The chipset cost is such a small part of the Z690 price because (despite cynicism that they're extorting the impatient flagship market) the OEMs claim that the real costs are in PCIe 5.0 and so many PCIe 4.0 lanes. The H670 has so many of those that the entry-level H670 boards are probably going to be $200 and that's still a hell of a lot for a locked-down board.
If you need lots of PCIe lanes, there's no reason not to get the Z690. If you don't need the lanes then the B660 boards should be waaaay cheaper with half of the Gen5, Gen4, lanes and a narrower chipset bus that will invariably translate to fewer layers of PCB as well.
What you are paying a lot more for is the PWM circuitry, as there's a combination of a shortage of the components and as we know, much bigger power draw from these CPUs, so the board makers have had to put in better PWM designs even at the lower-end. This has probably added something like $10 per board and even H610 boards will need that.
How does the B660 have half the PCIe 5.0 lanes?
0nm7nm!Are you saying that PWM circuitry supply chain issues are what are driving up the costs and that if the Asus Z590 was launched today it would be at least $50 more than it was 8 months ago? I don't really know how much of the BOM the PWM components actually make but one of the main citiations the board manufacturers used for the Z590 vs Z490 price hikes were the complexity of the PCBs to deal with PCIe 4.0. You're saying it's PWM components, the manufacturers were saying something different, If you have a link to the PWM supply issue changing drastically in the last 8 months I'd like to have a read but I just assumed the dire PWM IC shortage was ongoing from 15 months ago and hadn't changed enough to be newsworthy - there certainly don't seem to be any recent headlines.
I never said the new PCB materials don't add some cost, but the PCB material is still a form of fibreglass, just a much higher quality one, which still doesn't add a huge amount of extra cost.
I don't have any third party source, I just know what I've been told by people that work at the board makers. I mean, I do know a few people in the industry after all, so it's not hard for me to ask questions. The difference is, as far as I can tell, that they had placed the orders for the 500-series boards before the shortage really kicked in, whereas that wasn't the case for the 600-series boards. I will get back to you about the cost difference between feature similar/identical Z690 vs. H670 boards, as I've asked about that too, but won't find out until tomorrow.
There are other reasonable ways to cut costs. Not including PCIe 5 at all would be one, along with no DDR5. That should be perfectly fine for entry-level H670 and most (or maybe all) B560 boards.
Z690 boards start at 190 € including EU VAT. H670 will start at 130 €, B660 at 100 €, and H610 at 90 €, at least if 400- and 500- series boards are any indication for the future.
H670 is unlikely to be that much cheaper than Z670, at least not on feature for feature like boards. As explained above, the board makers have had to change their PWM parts over to more expensive parts, due to some products being EOL and as such being forced to use more costly solutions, that are costing even more now due to the component shortage.
The new normal is expensive.
Anyhow, trying to get some actual data on what the cost increase of Z690 vs. Z590 is and if I can get something that makes sense, I'll put up a news post about it.
A H670 with a 12700F and 4000 mhz will be a killer setup
H610 board
16GB dual-channel DDR4-3200 CL16
i3-12100
either iGPU or something like 1050 Ti or 1650
512GB PCIe 3.0 x4 boot drive
a SATA HDD or SSD
USB 3.1 connectivity
(I have only included parts that I think make sense in a H610 system)
Edit: USB 3.1 (10G), not 3.0 (5G)
I wonder if intel set VRM standards in the specs for the chipsets as well
