Intel 800 Series Chipsets: Full Desktop Lineup

The Intel 800 series chipsets for desktop PCs currently include the Z890, B860, and H810, with the Q870 and W880 aimed at business and workstation users. These chipsets support Intel Core Ultra 200-series processors (codenamed Arrow Lake-S) and use the new LGA 1851 socket.

Background: What the 800 Series Replaces

The 800 series is the successor to the 700 series (Z790, B760, H770, etc.), which supported 12th through 14th Gen Core processors on the LGA 1700 socket. The move to LGA 1851 and the new Arrow Lake architecture marks a significant shift: the memory controller now supports DDR5 only (no DDR4), and the chipset itself handles more I/O than before. Intel also changed the naming scheme, dropping the “7” and moving to “8” to align with the Core Ultra 200 processor generation.

For most buyers, the 800 series is the only way to use a Core Ultra 200 desktop CPU. Older 700-series boards do not work with these processors, and 800-series boards do not support older CPUs. If you’re building a new PC in late 2024 or 2025, the 800 series is your chipset family.

Available Models and Their Positioning

Intel has released four consumer-focused 800 series chipsets, plus two that target specific niches. Here’s the full desktop lineup as of early 2025:

• Z890 – The flagship, unlocked for overclocking CPU and memory. It offers the most PCIe lanes, the most USB ports, and support for Thunderbolt 4 (optional on some boards).
• B860 – The mainstream choice, with no CPU overclocking but full memory overclocking (XMP/EXPO). It has fewer PCIe lanes and USB ports than Z890 but is still plenty for most gamers.
• H810 – The budget option, with the fewest features: no overclocking, limited PCIe lanes, and fewer USB ports. It’s aimed at basic office PCs and entry-level builds.
• Q870 – A business-focused chipset with vPro support and Intel Stable Image Platform Program (SIPP) for long-term stability. It doesn’t support overclocking.
• W880 – Workstation-oriented, with support for ECC memory (on compatible CPUs) and more PCIe lanes for professional workloads. It’s not typically sold in retail boards.

All 800 series chipsets use the same LGA 1851 socket, but not all boards are created equal – the chipset determines which features you get.

Key Features and Differences

Here’s a quick comparison of the consumer chipsets (Z890, B860, H810) based on Intel’s official specifications:

• Overclocking: Z890 allows CPU and memory overclocking; B860 allows memory only; H810 allows neither.
• PCIe 5.0 lanes from chipset: Z890 has up to 20, B860 has up to 14, H810 has up to 8 (though most boards use PCIe 4.0 for chipset lanes).
• Total USB ports (max): Z890 up to 24, B860 up to 20, H810 up to 14.
• Thunderbolt 4 support: Z890 has it (optional on boards), B860 has it (optional), H810 does not.
• Wi-Fi 7 support: All three can support Wi-Fi 7 via the Intel Wi-Fi 7 BE200 module, but it’s an add-on, not built into the chipset.

In practice, the biggest difference you’ll notice is overclocking and the number of M.2 slots. Z890 boards typically have 4-5 M.2 slots, B860 boards have 3-4, and H810 boards have 1-2. If you’re a gamer who wants a fast NVMe drive, B860 is usually the sweet spot.

How to Choose the Right Chipset for Your Build

Choosing between the 800 series chipsets comes down to your budget and what you plan to do with the PC. Here’s a practical guide:

• Z890 – Choose this if you’re buying a K-series (unlocked) processor like the Core Ultra 9 285K or Core Ultra 7 265K and want to overclock. You’ll also benefit from the extra PCIe lanes if you plan to run multiple GPUs or many high-speed SSDs.
• B860 – The best choice for most gamers and content creators who don’t need CPU overclocking. You still get memory overclocking (so you can use high-speed DDR5 kits) and enough PCIe lanes for a fast GPU and a couple of M.2 drives.
• H810 – Select this for a budget office build or a basic home PC. It’s fine for everyday tasks and light gaming, but you’ll be limited on storage expansion and USB ports.
• Q870/W880 – Only relevant if you’re buying a pre-built business or workstation system. You won’t find these in typical retail motherboards.

Also consider the CPU you’re pairing: the Core Ultra 5 245K works with any 800 series chipset, but you lose overclocking on B860/H810. If you never plan to overclock, B860 saves you money without sacrificing real-world performance.

Common Misconceptions and Pitfalls

One common mistake is assuming that all 800 series boards support the same features. For example, some B860 boards might have a PCIe 5.0 x16 slot for the GPU, while others use PCIe 4.0 – it depends on the board manufacturer, not the chipset. Always check the specific motherboard’s spec sheet.

Another misconception is that you can use DDR4 RAM with the 800 series. You cannot – the memory controller in Arrow Lake is DDR5-only. If you’re upgrading from a 12th/13th/14th Gen system, you’ll need to buy new DDR5 memory.

Also, the LGA 1851 socket is physically different from LGA 1700, so you cannot use an older cooler that only supports LGA 1700 unless the manufacturer provides an LGA 1851 mounting kit. Most aftermarket coolers now include this, but check before you buy.

Comparison with AMD’s Current Chipsets

If you’re deciding between Intel and AMD, it’s helpful to see how the 800 series stacks up against AMD’s B650/X670 (and newer B850/X870) chipsets. Both platforms support DDR5 and PCIe 5.0, but there are key differences:

• Socket longevity: AMD’s AM5 socket is expected to support future Ryzen generations, while Intel’s LGA 1851 is likely a one-generation socket (Core Ultra 200 only).
• Overclocking: AMD allows overclocking on most B-series boards, whereas Intel restricts CPU overclocking to Z890.
• PCIe lanes: AMD’s chipsets generally offer more PCIe 5.0 lanes for storage, but Intel’s Z890 has more total lanes.
• Price: B650/B850 boards are often cheaper than B860 boards, making AMD a strong value option.

For pure gaming, both platforms perform similarly with comparable CPUs. The choice often comes down to upgrade path and specific features like Thunderbolt (Intel has an edge) or ECC support (AMD has it on some boards).

Frequently Asked Questions

Do I need a Z890 board to use a Core Ultra 5 245K?

No. The Core Ultra 5 245K works with any 800 series chipset, including B860 and H810. You only lose the ability to overclock the CPU, which the 245K doesn’t benefit much from anyway. For most users, B860 is the better value.

Can I use DDR4 memory with an 800 series motherboard?

No. All 800 series chipsets and Core Ultra 200 processors support DDR5 only. There are no DDR4 boards for LGA 1851. If you’re upgrading from an older system, you’ll need to buy new DDR5 RAM.

Will my LGA 1700 cooler fit an LGA 1851 motherboard?

Not necessarily. The mounting holes are different, so you need a cooler that supports LGA 1851. Many aftermarket coolers ship with both brackets, but check the manufacturer’s compatibility list. If not, you can often request a free LGA 1851 mounting kit.

What is the difference between B860 and Z890 for gaming?

For gaming, the difference is minimal. Both support the same CPUs and DDR5 memory. Z890 adds CPU overclocking and more PCIe lanes, which matter only if you’re running multiple GPUs or many high-speed SSDs. For a single-GPU gaming build, B860 is the smarter buy.

Is the 800 series compatible with 14th Gen Intel processors?

No. The 800 series is only compatible with Core Ultra 200-series processors (Arrow Lake). Older 14th Gen, 13th Gen, and 12th Gen CPUs require a 700-series or earlier motherboard. There is no backward compatibility.

Do all 800 series motherboards have Wi-Fi 7?

No. Wi-Fi 7 is optional and depends on the motherboard model. Some boards include an Intel BE200 Wi-Fi 7 card, while others use Wi-Fi 6E or no wireless at all. Check the spec sheet before buying if Wi-Fi 7 is important to you.
