Socket S1 is the CPU socket type used by AMD for their Turion 64, Athlon 64 Mobile, Phenom II Mobile and later Sempron processors, which debuted with the dual core Turion 64 X2 CPUs on May 17, 2006.
Socket S1 is a 638 pin, low profile, ZIF, 1.27mm pitch socket. It replaces the existing Socket 754 in the mobile computing segment (e.g. laptops).
Socket S1 CPUs can include support for dual-channel DDR2 SDRAM, dual-core mobile CPUs, and virtualization technology, and compete with the mobile Intel Core 2 processor series.
Different generations of processors used variant pinouts of the S1 socket; processors were not necessarily compatible with a socket even if they fit mechanically.
