For those aroused by sockets

Fresh details about pinouts and I/O capabilities for Intel's upcoming Core Ultra 200 series CPUs, codenamed Arrow Lake-S, have been leaked on Twitter.

Jaykihn0, a Twitter user, purportedly revealed a comprehensive layout of the LGA1851 socket and insights into Arrow Lake's I/O configuration for mobile and desktop processors.

According to Jay, the I/O connectivity for Arrow Lake-S on desktops remains unchanged compared to Intel's Arrow Lake-HX processors for mobile devices. The only addition to Arrow Lake-S is an extra USB 2 port on the PCH (Platform Controller Hub).

Other features remain consistent, including support for PCIe 5.0, which provides a single x16 slot and one x4 M.2 SSD, and PCIe 4.0 support encompassing secondary PCIe slots, Gigabit Ethernet, and SATA ports.

The leak only applies to Arrow Lake-S's native connectivity. High-end LGA1851 motherboards should incorporate third-party controllers, allowing for more USB ports, Thunderbolt ports, and USB 4 ports. These enhancements cater to power users requiring more than the Arrow Lake platform offers.

 Lunar Lake differs significantly from Arrow Lake. Lunar Lake supports up to six USB 2 ports, two USB 3 ports, and, for the first time, two USB 3.2 Gen 2x1 ports. Additionally, Lunar Lake will natively support UFS (Universal Flash Storage) for the first time.

Despite its historical reputation for being slower than an asthmatic ant with a heavy load of shopping, UFS—particularly UFS 3.0, 3.1, and 4.0—has significantly improved its bandwidth lately. UFS 4.0-compatible storage solutions now offer speeds comparable to some slower PCIe 3.0 NVMe M.2 SSDs.
