German tech site ComputerBase uncovered that Intel's Haswell processor will ship in four socket variations. First up is the LGA1150, this will be the socket used for the Haswell desktop processors, while the rPGA 946 is a socket for notebooks that (theoretically) allow you to change the processor. Both sockets have a few pins less than the LGA1155 and rpGA988 used by Intel's Ivy Bridge lineup.
Ivy Bridge was offered in two BGA packages; a 1023-pin version for the dual-core and a 1224-pin model for the quad-core CPUs. Haswell will be offered in BGA1168 and BGA1364 packages, but it's unknown if one model is for dual-core and the other for quad-core, perhaps this time the difference lies between SoC and dual-chip module.
