Intel’s next-gen LGA-1851 socket pinout leaks out, Core Ultra 200 platform I/O suppor

Intel LGA-1851 socket uncovered

A pinout map was shared by Jaykihn. 



The upcoming S (desktop) and HX (mobile) platforms are set to feature very similar I/O capabilities. The HX variant, essentially a desktop-class CPU in a BGA package, shares almost identical architectures with its desktop counterpart. The key difference lies in an additional USB2 lane (literally one) present on the HX platform.

Both the Core Ultra 200K desktop PCs and Core Ultra 200HX mobile workstations/high-end gaming laptops will support PCIe Gen5 for graphics. However, initial models of these laptops are expected to stick with the GeForce RTX 40 series, which does not support this standard. Nonetheless, PCIe Gen5 support will become more prevalent, especially in terms of storage, with at least one 4-lane connection becoming commonplace on Intel devices.

Unlike ARL-S and HX, the Arrow Lake-H represents a significantly reduced version, featuring PCIe Gen5 lanes reduced from 20 to only 8. Mobile graphics typically do not use more than 8 lanes anyway, and it seems that the SOC lanes are still Gen4. Worth noting that the low-power Core Ultra 200V “Lunar Lake” will also support PCIe Gen5 but with lanes reduced even further to 4. This configuration is sufficient to support a single SSD utilizing this interface.
