Socket P

The Intel Socket P (mPGA478MN) is the mobile processor socket replacement for Core microarchitecture chips such as Core 2 Duo. It launched on May 9, 2007, as part of the Santa Rosa platform with the Merom and Penryn processors.

Technical specifications
Intel Core 2 Duo T9600 CPU showing Socket P

The front-side bus (FSB) of CPUs that install in Socket P can run at 400, 533, 667, 800, or 1066 MT/s. By adapting the multiplier the frequency of the CPU can throttle up or down to save power, given that all Socket P CPUs support EIST, except for Celeron that do not support EIST. Socket P has 478 pins, but is not electrically pin-compatible with Socket M or Socket 478. Socket P is also known as a 478-pin Micro FCPGA or μFCPGA-478. On the plastic grid is printed mPGA478MN.
