Leaked Arrow Lake diagram show more PCIe lanes, no DDR4, 2 M.2 SSD ports to CPU

The leaked Intel Arrow Lake chipset diagram reveals significant upgrades, including more PCIe lanes and no support for DDR4. The new chipset features two M.2 SSD ports directly connected to the CPU, supporting PCIe 5.0 lanes for graphics cards and storage. It abandons DDR4 in favor of DDR5 due to decreased DDR5 prices. Additionally, the CPUs will integrate Thunderbolt 4 controllers and support up to four displays through integrated Arc Xe-LPG graphics. The chipset also confirms USB 3.2 Gen 2x2, Gen 2x1, and Gen 1 connections, along with 1GbE and optional 2.5GbE networking support. The upcoming LGA-1851 platform events will introduce Intel's new 800-series motherboards to distributors and board partners. While the leaked information should be taken with caution, it provides insights into the advancements expected in the Arrow Lake-S processors and associated motherboards.

> 2 M.2 SSD ports to CPU

That should read two PCIe x4 ports to the CPU intended for attaching SSD storage. Otherwise it sounds like a dedicated SSD port which it clearly isn't.

16x + 4x of PCIe 5.0, and a new 4x of PCIe 4.0. Then the DMI 4.0 8x for the chipset.

Pretty minor addition. Still, makes sense.
