INTRODUCTION
• A Central Processing Unit (CPU), or sometimes just called
processor, is a description of a class of logic machines that can
execute computer programs.
• Intel Core i7 is a family of three Intel desktop processors, the
first processors released using the Intel Nehalem micro
architecture and the successor to the Intel Core 2 family. All
three models are quad-core processors.

BASICS
 In computer architecture, 32-bit integers, memory
addresses, or other data units are those that are at most
32 bits wide. Hence, 32-bit CPU and ALU
architectures are those that are based on registers,
address buses, or data buses of that size.
 In computer architecture, 64-bit integers, memory
addresses, or other data units are those that are at most
64 bits wide. Also, 64-bit CPU and ALU architectures
are those that are based on registers, address buses, or
data buses of that size.

FEATURES
 SOCKET : The Socket is a new LGA1366(Socket
B) and is incompatible with the previous versions.
 LGA refers to Land Grid Array, a new type of
socket for the latest range of processors. The LGA is
used as a physical interface for microprocessors of the
Intel Pentium 4, Intel Xeon and Intel Core 2.

ON-DIE MEMORY CONTROLLER :The memory is
directly connected to the processor.
 Three channel memory: each channel can support
one or two DDR3 RAM’s. Motherboards for Core i7
have four or six RAM slots.
 Supports DDR3.
 DDR3 RAM (double-data-rate three random access
memory ) is a random access memory technology used
for high speed storage of the working data in the
computer.

More About Processor
The speed of data transfer is 25.6 Gbps, almost double
that of FSB.
Clock Speed 1.2 GHz (slowest) & 3.5 Ghz (fastest) or
3.9GHz via Turbo Boost Technology
The cost per piece is INR. 47,000.
7

Cache Memory
 32 KB L1 instruction and 32 KB L1 data
cache per core.
 256 KB L2 cache (combined instruction and
data) per core.
 8 MB L3 (combined instruction and data)
shared by all cores.

 In a test performed on a leaked hardware, the core i7
outperformed the currently fastest core extreme
processor.
 It has got the advantages of High Performance, Big
Cache Size, Very Fast, Highly Overclockable, Quite
Cooling and Power Efficient.
 The technology keeps on improving as the need for
faster and high end applications increases. The
8 core version is about to be released soon.
