Big improvements – Intel LGA-1851 Arrow Lake platform diagram leaks
Intel LGA-1851 platform diagram reveals extended PCIe 5.0 support and more
Over on Chiphell, via @9550pro, a platform diagram of Intel’s upcoming LGA-1851 (Z890) motherboard platform has leaked. This diagram has revealed the major platform upgrades that Intel will be delivering with their Arrow Lake-S desktop CPU platform, which is due to launch later this year.
For starters, Intel’s new motherboard platform will feature extended PCIe 5.0 support. There will be 16 PCIe 5.0 lanes for PCIe devices, and an additional four PCIe 5.0 lanes for M.2 SSD storage solutions. This is a huge upgrade for Intel’s Arrow Lake CPU platform, as this allows users to have a full x16 PCIe 5.0 configuration for future GPUs and full PCIe 5.0 M.2 SSD support. With current generation Intel platforms, there is only 16 PCIe 5.0 lanes. This means that the main x16 PCIe lane on motherboards only has access to eight PCIe lanes when PCIe 5.0 M.2 SSDs are used.
Intel’s 800-series motherboard shipset can also feature support for USB 3.2 Gen 2X2, WIFI 7, and 2.5 Gb ethernet. Intel’s new CPUs will also feature support for up to two Thunderbolt 4 ports. These CPUs will support DDR5 memory exclusively, unlike Intel’s last-generation platform, which supported both DDR4 and DDR5.

It’s clear that Intel’s LGA-1851 motherboard platform is a requirement for Intel’s next-gen Arrow Lake CPUs. These new CPUs will not be backwards compatible with older 600-series or 700-series motherboards. That means that Intel LGA-1851 motherboards will become available this year alongside Arrow Lake.
