INTRODUCTION
What is Processor ?
A processor is multipurpose, programmable
device that read binary instructions from
memory, accepts binary data as input and
processes data according to that instruction,
and provides results as output. It can be viewed
as data processing unit of a computer. It has
computing and decision-making capability.

INTRODUCTION
Central Processing Unit
A central processing unit (CPU), also referred
to as a central processor unit, is the hardware
within a computer that carries out the
instructions of a computer program by
performing the basic arithmetical, logical, and
input/output operations of the system.

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.

INTEL CORE
• Intel Core is a brand name used for various mid - range to
high-end consumer and business micro processors made by
Intel.
• Identical or more capable versions of Core processors are
also sold as Xeon processors for the server
 The current Core processors
 Intel core i7
 Intel core i5
 Intel core i3
 The old core processors include:
 Intel core 2 solo
 Intel core 2 Duo
 Intel core 2 Quad
 Intel core 2 extreme

INTEL CORE
Enhanced Pentium M based :
The original Core brand refers to Intel’s 32 bit mobile dual core x86 CPU s that
derived from the Pentium M branded processors.
Core Duo :
Intel Core Duo (product code 80539) consists of two cores on one
die, a 2 MB L2 cache shared by both cores, and an arbiter bus that controls
both L2 cache and FSB(Front side bus).
Core Solo :
Intel Core Solo (product code 80538) uses the same two-core die as
the Core Duo, but features only one active core. This allows Intel to sell dies
that have a manufacturing defect in one but not both of the cores.

INTEL CORE
64 bit micro architecture based :
The successor to Core is the mobile version of the Intel core 2 line of
processors using cores based upon the Intel Core micro architecture released
on July 27, 2006.
Core 2 Solo :
The Core 2 Solo introduced in September 2007, is the successor to
the Core Solo and is available only as an ultra-low-power mobile processor
with 5.5 Watt thermal design power.
Core 2 Duo :
The majority of the desktop and mobile Core 2 processor variants
are Core 2 Duo with two processor cores on a single Merom , Conroe ,
Allendale, Penryn or Wolfdale chip.

INTEL CORE
Core 2 Quad :
Core 2 Quad processors are multi chip modules consisting of two dies
similar to those used in Core 2 Duo, forming a quad-core processor. This
allows twice the performance of a dual-core processors at the same clock
frequency.
Core 2 Extreme :
Core 2 Extreme processors are enthusiast versions of Core 2
Duo and Core 2 Quad processors, usually with a higher clock frequency
and an unlocked clock multiplier.

INTEL CORE
Nehalem micro architecture based :
The Nehalem micro architecture Intel introduced a new naming scheme for it .
The Core i3 was intended to be the new low end of the performance
processor line from Intel
Core i3 :
The first Core i3 processors were launched on January 7, 2010. The first
Nehalem based Core i3 was Clarkdale based Core processors. There are
three variants, Core i3, Core i5, and Core i7.
Core i5 :
Core i5, like Core i7, is based on the Nehalem micro architecture. The first
Core i5 was introduced on September 8, 2009 and was a mainstream
variant of the earlier Core i7.

INTEL CORE
Core i7 :
The Core i7 brand remains the high-end for Intel's desktop and mobile
processors, featuring the Sandy Bridge models with the largest amount of
L3 cache and the highest clock frequency.
Processors :
• The initial Core i7 processors released were codenamed Bloomfield,
branded as Core i7-9xx along with their Xeon 3500-series counterparts.
• Lynnfield is the second processor sold under the Core i7 brand, while at
the same time being sold as Core i5
• The second mobile Core i7 processor family is Arrandale, sold as the Core
i7-6xx processors
• Sandy bridge is the second generation Intel Core i7 series processor, and is
based on micro architecture

FEATURES of i7
1. 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, Intel Core 2 and AMD Opteron families.
Unlike the pin grid array (PGA) interface found on most AMD and older
Intel processors, there are no pins on the chip; in place of the pins are pads
of bare gold-plated copper that touch pins on the motherboard.
 Intel supposedly decided to switch to an LGA socket because it provides a
larger contact point, allowing, for example, higher clock frequencies. The
LGA setup provides higher pin densities, allowing more power contacts and
thus a more stable power supply to the chip.

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.
• The benefit of DDR3 is the ability to run its I/O bus at four times the speed of
the memory cells it contains, thus enabling faster bus speeds and higher peak
throughput than earlier memory technologies.
• The DDR3 standard allows for chip capacities of 512 megabits to 8 gigabits,
effectively enabling a maximum memory module size of 16 gigabytes.
• There is a significant reduction in power consumption. It needs only 1.5V
compared to 1.8V for DDR2.

FEATURES of i7
3. Quick Path Interconnect: he front side bus is replaced by Quick Path
interconnect. Motherboards must use a chipset that supports Quick Path.
 the Front Side Bus (FSB) is the bus that carries data between the CPU and
the north bridge.
 Front side buses serve as a connection between the CPU and the rest of the
hardware via a so-called chipset. This chipset is usually divided in a north
bridge and a south bridge part, and is the connection point for all other
buses in the system
Pros: FSB architecture is an aging technology. High flexibility , low cost and no
theoretical limit to the number of CPUs that can be placed on a FSB.
Cons: In recent years this has been breaking down with increasing use of
individual point-to-point buses (see Hyper Transport and Quick Path). The
front side bus has been criticized by AMD as being an old and slow
technology that bottlenecks today's computer systems.

FEATURES of i7
 The Intel Quick Path Interconnect (QPI) is a point-to-point processor
interconnect developed by Intel to compete with Hyper Transport. It will
replace the Front Side Bus (FSB) for Desktop.
 The speed of data transfer is 25.6 Gbps, almost double that of FSB.
4. 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.

FEATURES of i7
(a). Re-implemented Hyper-threading.
 Each of the four cores can process up to two threads simultaneously, so the processor
appears to the OS as eight CPUs.
 Hyper-threading (officially termed Hyper-Threading Technology or HTT) is an Intel
technology used to improve parallelization of computations performed on PC
microprocessors.
(b). 781M transistors for the quad core version.
(c ). Sophisticated power management can place an unused core in a zero-power mode.
5. Support for SSE4.2 & SSE4.1 instruction sets.
 SSE4 is an instruction set used in the Intel Core microarchitecture and AMD.
 Intel SSE4 consists of 54 instructions. A subset consisting of 47 instructions, referred to as
SSE4.1. Additionally, SSE4.2, a second subset consisting of the 7 remaining instructions,
will first be available in Core i7.

FEATURES of i7
6. Overclocking : Overclocking is the process of forcing a computer
component to run at a higher clock rate (more clock cycles per
second) than it was designed for or was designated by the
manufacturer, usually practiced by personal computer enthusiasts in
order to increase the performance of their computers.
 The idea is simple by varying the electrical and physical characteristics
of computing systems.
 The first consideration is to ensure that the component is supplied
with adequate power to operate at the new speed. However,
supplying the power with improper settings or applying excessive
voltage can permanently damage a component.
