Intel Core i7 processor families
The latest generation of high-performance Intel x86-compatible microprocessors, branded Core i7, was released on November 17, 2008. Intel Core i7 microprocessors are based on new Nehalem microarchitecture, which, like AMD K8 microarchitecture, replaces Front-Side Bus interface with on-die memory controller with its own dedicated memory bus, and a separate QuickPath Interconnect (QPI) controller that uses point-to-point protocol to communicate with I/O devices and other processors in multi-processor systems. Server-class Core i7 CPUs have two point-to-point links. Other major features of the Nehalem microarchitecture include:
There are many other performance improvements in Core i7 processors, such as enhanced branch prediction, secondary 512-entry TLB buffer, new SSE4.2 instructions, and others.
Intel Core i7 microprocessors are packaged in 1366-land Land-Grid Array (LGA) package, and require socket 1366 motherboards. Future Core i7 processors may also be packaged into 1156-land LGA package.
