Intel's Upcoming 800-series Chipsets Leak in Detail
What appears to be the full details of all of Intel's upcoming 800-series chipsets have leaked and although we've already seen what the Z890 chipset will offer, no details of the other SKUs have leaked to date. Maybe the biggest news is that there won't be an H870 chipset this time around, according to the leaker @jaykihn0 over at X/Twitter. The full range appears to be Z890, B860 and H810 for consumers, W880 for workstations and Q870 for corporate desktops. That said, the Z890 and W880 are identical in terms of slots and ports, but whereas the W880 gains full ECC support and Intel vPro and remote management, it loses the CPU and bus overclocking features of the Z890. The Q870 loses four chipset PCIe 4.0 lanes, one 20 Gbps or two 10 Gbps USB 3.2 ports, but is otherwise similar to the Z890, minus all the overclocking features, but with Intel vPro and remote management.
The B860 ends up on the chopping block as always and loses not only 10 chipset PCIe lanes compared to the Z890 chipset, but also four lanes from the CPU and four lanes on the DMI interface to the chipset. On top of that bifurcation goes out the window toigether with PCIe RAID and the chipset is only capable of having two 20 Gbps or four 10 Gbps USB 3.2 ports, but at least memory overclocking is still on the table. Finally, the H810 chipset is as basic as it gets, with no extra CPU PCIe lanes beyond the 16 lanes for a graphics card, but they are at least PCIe 5.0 this time around. The chipset itself is only equipped with a mere eight PCIe 4.0 lanes and it gets zero 20 Gbps and two 10 Gbps USB 3.2 ports. Note that all platforms support one or two Thunderbolt 4 / USB4 ports, but it's unclear if this is native support or via an add-on chip. Also note that the USB ports are shared and the maximum count is that for the 5 Gbps ports in the details below, so the Z890 for example, doesn't have 25 USB 3.2 ports in total, but rather only 10. All in all, we'll see a migration to PCIe 5.0 for the x16 slot across the entire 800-series chipset range and from the B860 and up, all chipsets will have a dedicated PCIe 5.0 x4 interface that will most likely be used for an M.2 slot. Also, the PCIe lane count is the maximum, but due to Intel's HSIO layout, some resources will be shared with SATA and Ethernet, which means not all PCIe lanes will be accessible.
