Intel Arrow Lake & Lunar Lake I/O Configurations Revealed Along With LGA 1851 Socket Pinout Plan

Intel's next-gen Arrow Lake & Lunar Lake CPUs will offer a diverse set of IO configurations which have been revealed by @jaykihn0.

Intel's Arrow Lake & Lunar Lake "Core Ultra 200" CPUs To Feature Gen5 Support Across All PC Platforms

Intel is working on a diverse range of CPU platforms, ranging from high-end desktops to thin & light designs. These platforms will feature the upcoming Core Ultra 200 "Arrow Lake" & Core Ultra 200V "Lunar Lake" CPU families. We have already done a deep-dive of the Lunar Lake architecture & also covered Arrow Lake quite extensively in the past and now we have some more info when it comes to the IO capabilities of each respective chip platform.

Starting with the top Intel Arrow Lake-S Desktop CPUs, the SOC Tile will feature 16 PCIe Gen5 lanes dedicated to discrete graphics, the IOE Tile will feature 4 Gen5 lanes and 4 Gen4 lanes dedicated to M.2 SSDs while the PCH (800-series) will offer up to 14 Gen4 lanes, 7 Gen4 for SATA and 2 Gen4 for dual GbE LAN connections. There will also be 13 USB2 and 10 USB3 lanes. The Arrow Lake-HX CPUs will be similar to the desktop offerings since they are based on a similar die. The only difference is one extra USB2 lane.

Moving down the stack, we have the Intel Arrow Lake-H CPUs which will feature 12 Gen4 lanes on the SOC tile, 8 Gen5 lanes for discrete graphics, 8 Gen4 lanes for M.2 (x4/x4) on the IOE tile, & with a combination of 10 USB2 plus 2 USB3 lanes on the PCH tile. The lower-end Arrow Lake-U chips are not mentioned but we can expect IO similar or slightly cut-down as the Arrow Lake-H SKUs.

Lastly, we have Intel's Lunar Lake CPUs which will feature all IO capabilities on the SOC tile. It will offer UFS (1x2), Gen4 (GBE x1), Gen4 (x3), Gen5 (x4), USB 3.2 Gen2x1 (x2), USB3 (x2) and USB2 (x6) lanes.
