Intel 800-series chipsets details leak out: CPU overclocking exclusive to Z890 - VideoCardz.com

Intel 800-series for Arrow Lake-S CPUs detailed

The next-gen platform will be divided into 5 chipsets.

Contrary to what the Computex showcase of Intel’s “next-gen” motherboard lineup might have suggested, the Z890 chipset isn’t the only one currently being developed. Various leaks from motherboard makers and certification offices have shown that these companies are also working on B860 and H810 motherboards for the consumer segment. The future of the H870 chipset (not included in this comparison) remains uncertain, according to Jaykihn, a new source in the Intel scene. He has been sharing some preliminary details on the Intel Core Ultra 200 series, be it Arrow Lake or Lunar Lake.

The upcoming series of LGA-1851 motherboards should be unveiled in full in the next 6 months, assuming we include the CES 2025 showcase. Currently, we know that the Z890 series will take the spotlight with the arrival of the Core Ultra 200K unlocked series, which should happen in early Q4. These are high-end SKUs designed for enthusiasts who have no problems with overclocking (and paying extra). The Q870 and B860 series might appear a bit later, with the Ultra non-K series expected to debut at CES.

Jaykihn has now shared a spec sheet featuring all five planned chipsets for the Intel 800-series. This also includes the W880 workstation chipset, likely to power the Arrow Lake-based Xeon series.

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.

Perhaps the most interesting detail for consumers is that the Z890 will still be the only official platform supporting CPU overclocking, specifically the voltage for X86 cores (IA) and BCLK (base clock) adjustment. Users will still be able to overclock memory on the B860 platform, but this feature is not supposed to work on the Q870 and H810 chipsets.

The lack of support for next-gen B860 chipsets means that AMD’s B650 and upcoming B850 series will still have an advantage, as AMD does not limit overclocking on their mid-range segment. The only exception is the A620 chipset, which will continue to be sold alongside AMD’s 800-series.

The table also confirms that the W880 will remain the only chipset supporting DDR5 ECC memory (not to be mistaken with DDR5 built-in data checking), though this platform won’t support CPU overclocking either.

Total PCIe lane support will go up to 48 on the Z890 and W880 and will be limited to 24 lanes on the H810 chipset. Notably, the B860 will support PCIe 5.0 x16 and x4 interfaces through the CPU, meaning it isn’t just the Z890 supporting potential 5.0 GPU and SSD configurations. However, switching to the B860 chipset will result in losing the secondary PCIe 4.0 x4 support through the CPU.
