Intel 800-Series Chipsets Detailed: Z890 With IA, BCLK & Memory OC, W880, Q870, B860 & H810 Without CPU Overclocking

Intel's next-gen 800-series chipsets including Z890, W880, Q870, B860 & H810 have been detailed along with their OC capabilities.

Based on the latest leak by @jaykihn0, we have details surrounding the entire 800-series chipset family which includes a total of five SKUs. The SKUs include the top Z890 PCH followed by W880, Q870, B860 & H810. The leaker states that this is preliminary data but it looks like H870 won't be launching within the 800-series family. It is also reported that these specifications (I/O & OC) are only valid for the Arrow Lake-S "Core Ultra 200" Desktop CPUs and may vary with the Non-K and Xeon mainstream families. These chipsets will be incorporated on the next-gen LGA 1851 socket motherboards.

Intel 800 Series Chipset Specifications.

Preliminary, but I doubt it’ll change before launch.

No H810 sku.

These specifications are valid with Arrow Lake -S.

Be advised that ARL-S may not be the only architecture on 800 series chipsets. pic.twitter.com/diZqVSjsJA

Starting with the very top, we have the Intel Z890 chipset which will be coming to several high-end motherboards in October when the Arrow Lake-S lineup debuts. The motherboards will feature a total of 60 HSIO lanes which are divided into 26 from the CPU and 34 from the PCH. We know from previous reports that Intel's Arrow Lake-S CPUs include 24 PCIe lanes (x16 Gen5 + x4 Gen5 + x4 Gen4).

The Z890 chipset will offer around up to 48 PCIe lanes with 2 USB4/TB4 ports, 8 lanes dedicated to DMI (Gen4), 24 PCIe 4.0 lanes, 8 lanes for SATA III (6 Gbps), 14 USB2 ports, 5 USB 3.2 (20G) ports, 10 USB 3.2 (10G) ports, and 10 USB 3.2 (5G) ports. The W880 chipset is also very similar to Z890 but in terms of OC support, the workstation-oriented family will only support memory overclocking (XMP).

On The Z890 front, Intel will offer CPU IA, BCLK, and Memory overclocking capabilities and this is the only chipset that supports all three overclocking capabilities. The W880 chipset does get ECC DRAM support. The Q870 and H810 chipsets will feature fewer lanes and IO but no overclock capabilities while the B860 chipset will feature just memory overclocking support but also with a lower number of lanes and IO. Following is the full configuration of each chipset:

The B860 and H810 chipsets see quite a reduction in total number of PCIe lanes, falling to 45/33 total HSIO and 34/24 total PCIe lanes. The B860 chipset will be able to offer support for just one PCIe 5.0 x16 graphics card and a single PCIe Gen 5.0 x4 M.2 SSD while the H810 chipset will be supporting just one PCIe 5.0 x16 graphics card through the CPU lanes. The PCIe 4.0 lanes are just 14 for B860 and 8 for H810. Hopefully, we can see the motherboards based on the respective chipsets to be priced accordingly for the entry-level segment.

Having no CPU overclocking support on the mainstream motherboards will be a major miss for Intel since the competition has been offering OC support on their mainstream products since the AM4 generation.

Intel's motherboard partners did offer BCLK OC support through BIOS updates and by offering BCLK OC generators on last-gen "B" series motherboards but Intel took strict action and told motherboard vendors to remove such support claiming that it voids the warranty of the CPUs such as the Non-K family which doesn't support any overclocking. AMD on the other hand not just provides overclocking support on its "B" series motherboards but also supports overclocking on non-X CPUs which makes them great options for mainstream consumers.

Intel Arrow Lake-S Desktop CPUs will be heading to the next-gen LGA 1851 socket featured on 800-series motherboards with the following features:

Once again, the Intel Arrow Lake-S Desktop CPUs will be launching alongside the first 800-series motherboards, the Z890 series, by October so stay tuned for more information if you want to look at what each manufacturer has on offer for their respective Z890 motherboards, you can check out our Computex coverage below:
