Definition of Intel Core I7 Processor
Intel core i7 is a family of three Intel desktop processor, the first processor released using the Intel Nehalem micro architecture and the successor to the Intel Core 2 family. All three models are quad core processors.
A quad core processor consists of four cores. Quad core technology is a type of technology that includes two separate dual-core dies, where dual-core means a CPU that includes two complete execution cores per physical processor, installed together in one CPU package. In this setup cores 1 and 2 would share a memory cache, and core 3 and 4 another cache. Communication between core 1 and 2 and core 3 and 4 using QPI(Quick Path Interconnect)
They are 64 bit processors. In computer architecture, 64-bit integers, memory addresses, or other data units are those that are at most 64 bits (8 octets) wide. Also, 64-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size.
The need for core i7 processors requires a comparison with their immediate predecessors. The comparison can be summarized as follows. The Core i7 is a completely new architecture which is much faster and more efficient than the Core 2 Duo. Currently only the Core i7 920, 945 and 965 XE versions are available. Of that the Core i7 920 is available at just $284 which makes it a great buy. It offers better performance than almost all Core 2 Duo processors
Introduction of Intel Core I7 Processor
A cpu socket or cpu slot is an electrical component that attaches to a circuit board and is designed to house a cpu. It is a special type of IC socket designed for very high pin counts. A cpu socket provides many functions including providing a physical structure to support the cpu, facilitating replacement and cost reduction and as an electrical interface both with the cpu and the circuit board.
Core i7 uses an LGA1366 socket.(socket B). it is incompatible with the previous versions. LGA refers to Land Grid Array and is used as a physical interface for microprocessors of the Intel Pentium 4, Intel Xeon, Intel Core 2 and AMD Opteron families. Earlier the socket used was the PGA(Pin Grid Array). In LGA there are no pins on the chip .Instead there are pads of gold plated copper that touch pins on the motherboard. LGA provides a larger contact point, allowing for eg higher clock frequencies. It also allows higher pin densities and thus enables a more stable power supply to the chip
The memory is directly connected to the processor. The memory is divided into three channels. Each channel can support one or two DDR3 RAMs. Motherboards for core i7 have three or six RAM slots.DDR3 RAM is double data rate 3 random access memory. This is a RAM technology used for high speed storage of the working data of a computer or other digital electronic devices. The primary benefit of DDR3 is its ability to run its I/O bus at four times the speed of the memory cells contained in it. It enables faster bus speeds and higher throughputs than earlier memory technologies. There is a significant reduction in the power consumption. It needs only 1.5V compared to 1.8V for DDR2
