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.

Here are some of the first pictures of the 12th Gen Intel Core "Alder Lake" desktop processor models that are expected to join the lineup in January 2022. Intel debuted the series with unlocked "K" and "KF" SKUs, with "locked" SKUs saved for next year. Pictured here are the Core i9-12900, the Core i5-12600, the i5-12500, and the i5-12400. The S-SPEC codes for these processors are SRL4E, SRL4F, SRL4G, and SRL4P, respectively. Our older article details their possible specifications. The lineup isn't limited to these models. Others include the Core i7-12700, and the "F" variants of many of these SKUs, which lack integrated graphics, allowing those with discrete graphics cards to save a little.

Besides these processors, Intel is expected to expand its motherboard chipset options. Currently, Z690 is the only chipset option for the LGA1700 socket. Upcoming chipset models are likely to include the H670, W680, B660, and perhaps even the H610. Intel could use platform I/O for segmentation of these chipsets, besides lack of CPU overclocking support. A big change with the 12th Gen desktop processor lineup concerns Core i5. While the i5-12600K and i5-12600KF feature 6 P-cores and 4 E-cores, the other Core i5 SKUs, including the i5-12600, lack E-cores. The source installed these processors to confirm that the i5-12600 is indeed based on the "H0" silicon and lacks E-cores.

Intel debuted its 12th Gen Core "Alder Lake-S" desktop processor family late last month with only the unlocked "K" and "KF" SKUs targeting gamers and PC enthusiasts, alongside only the top Z690 chipset motherboards. The company is preparing to expand the lineup early next year with the addition of at least seven more SKUs (excluding additional "F" variants that lack integrated graphics). These processors could also introduce more value-conscious motherboard chipsets, such as the B660 and H670. momomo_us on Twitter, a reliable source with hardware leaks, predicts specs and a possible mid-January launch date for these chips.

The lineup possibly includes the Core i9-12900 and i9-12900F at the top, followed by the i7-12700 and i7-12700F, and the meaty Core i5 lineup that includes the i5-12600 and i5-12600F; the i5-12500, and the i5-12400/F. At least two Core i3 series SKUs could also be launched. The possible clock-speeds, and L3 cache sizes for the SKUs are tabulated below. What stands out from these SKUs is the specs of the Core i5-12600. We earlier thought it would be based on the larger "C0" silicon, with 6 P-cores and 4 E-cores, but it turns out, that the SKU is based on the smaller "H0" silicon with just 6 P-cores and no E-cores. Read more about the two silicon variants of "Alder Lake-S" in our older article. The i5-12600 will have significantly different performance and energy efficiency numbers than the i5-12600K.

The ASUS PRIME B660-PLUS D4 has allegedly been inadvertently sent instead of an ASUS Z690 motherboard to a reviewer for Alder Lake testing. The reviewer provided images of the product packaging to VideoCardz which clearly show a label indicating PCIe 4.0 support. This has come as a surprise as the Intel 12th Generation Alder Lake processors include attached PCIe 5.0 lanes separate from the chipset. The B660 chipset will target the mid-range market so the lack of PCIe 5.0 support on this specific motherboard may be a cost-cutting or artificial separation measure.

The first consumer PCIe 5.0 graphics cards and SSDs aren't expected to arrive until H1 2022 and will likely come at a significant premium so the exclusion of support could make sense for a more budget-oriented platform. Intel is also preparing to launch a higher-end H670 chipset which is expected to include PCIe 5.0 support. We cannot be sure if this label is accurate and if the lack of PCIe 5.0 support will apply to all B660 motherboards so take these rumors with a healthy dose of skepticism until the chipset and motherboards are officially unveiled.

With Intel's Alder Lake processor generation launch, the platform merges support of two different DDR memory standards: DDR4 and DDR5. While there are motherboards that offer the latest DDR5 standard, there are boards that provide users to use the cheaper DDR4 memory option in their builds as we transition to the newer standard and newer memory becomes more available. The DDR5 products are currently on the expensive side, and DDR4 represents a good choice for creating a PC build in the following years, at least in the transition to DDR5 standard's better availability and lower prices.

According to Moore's Law is Dead Twitter account, the DDR4 support may reside for a little longer on Intel's platforms. As per their sources, Intel's 13th generation Core processors, codenamed Raptor Lake, will carry over DDR4 platform support and possibly retain compatibility with the 12th generation Alder Lake platform. That means that the Z690 and future H670/B660/H610 boards could be compatible with Raptor Lake-S and also carry support for the DDR4 memory protocol for it. This could indicate that Alder Lake-S buyers that build PCs with DDR4 memory could have a viable processor upgrade path without upgrading the memory. Of course, information like this should be taken with a grain of salt.

The lineup of 600-Series motherboards planned by ASRock and NZXT for the upcoming 12th Generation Intel Core Series of processors has recently been published by VideoCardz. While NZXT has only two high-end Z590 motherboards listed with them being the N5-Z69XT, and the N7-Z69XT, ASRock has 36 listed across all the Z690, H670, B660, and H610 chipsets. The Z690 chipset will serve as the flagship platform for high-performance and overclocking while the H670 and B660 will take the mid-range and the H610 for entry-level boards. The list does not contain any Taichi, Aqua, or OC Formula series boards from ASRock as those may not be ready for day-one release or are still under active development.

ASRock will offer several of their motherboards in two variants with one offering integrated WiFi 6E networking, they also have an ITX option for each chipset. Intel is expected to announce their 12th Generation Core Series processors and Z690 chipset in late 2021 with the remaining chipsets to be announced at CES 2022. The entire list of motherboards from the two companies can be found below.
