Intel accomplished a couple of noteworthy things with its Core i7 socket 1366 processor formfactor, the most noteworthy was integrating the memory controller directly onto the CPU die to substantially reduce the complexity of the motherboard. Major architectural changes were also brought about by the Intel Core i7 family of processors, but like the socket LGA775 Intel Core 2 Duo processors that preceded it, the Core i7 is a pinless chip. Removing the vulnerable and delicate interface pins from the bottom of a CPU make possible increasing pin densities that complex CPUs demand. It also increases the complexity and risk involved in installing one of the new socket LGA1366 processors into a motherboard.
