Intel Core 2 Quad processors are designed to fit two socket types.
Intel's Core 2 Quad lineup of processors includes 17 different CPUs, ranging from 2 to 3 gigahertz and containing 4 to 12 megabytes of cache. The processors feature 45- and 65-nanometer technology. Core 2 Quad processors and their associated sockets are available for both desktop and mobile platforms. Intel began selling processors for the former in 2007 and the latter in 2008.
LGA775
Most of the Intel Core 2 Quad processors fit the LGA775 socket type, which has 775 pins and is for desktop computers. The LGA775 socket reversed the location of the pins from previous CPUs, moving them into the socket rather than on the CPU itself. The socket supports Intel CPUs with speeds ranging from 1.8 gigahertz up to 3.8 gigahertz. Socket bus speed support ranges from 533 megahertz up to 1600 megahertz.
Socket P
The Intel Core 2 Quad processors for notebooks fit the Socket P (or PGA478) socket type. This socket has 478 pins and includes pins in the socket rather than on the processor. The socket is similar to Socket M and 478, both of which also have 478 pins, but Socket P processors are not compatible with Socket M and 478 processors. Intel CPUs compatible with Socket P are either 2 or 2.26 gigahertz and have either 6 or 12 megabytes of cache.
List of CPUs
These Intel CPUs fit the LGA 775 socket: Q9650, Q9550S, Q9550, Q9505S, Q9505, Q9500, Q9450, Q9400S, Q9400, Q9300, Q8400S, Q8400, Q8300, Q8200S, Q8200, Q6700 and Q6600.
These Intel CPUs fit Socket P: Q9100 and Q9000.
