Intel’s upcoming 800-series chipsets face some changes compared to previous versions. The B860 chipset will now have fewer PCIe lanes from both the chipset itself and the CPU, along with the removal of branching capabilities, PCIe RAID, and decreased USB speeds. On the other hand, the H810 chipset is very basic, with limited PCIe lanes and USB ports. Both chipsets support Thunderbolt 4/USB4, but it is unclear if this is native support. Additionally, the number of USB ports across the platforms may be misleading, as they are shared and not all 5Gbps ports.
Moving forward, there will be a shift to PCIe 5.0 for the x16 slot in the 800-series chipset range, and all chipsets from B860 onwards will have a dedicated PCIe 5.0 x4 interface, likely used for an M.2 slot. However, due to Intel’s HSIO design, some PCIe lanes will be shared with other resources like SATA and Ethernet, limiting the accessibility of all lanes.
Overall, the upcoming 800-series chipsets from Intel show a trend towards maximizing the capabilities of PCIe 5.0 technology, but with some limitations in terms of PCIe lane accessibility and other resources. The changes in these chipsets reflect the evolving needs of the technology industry and the growing demands of high-speed data transfer and performance.
