3. Introduction
The Intel® Core™ i5-700 desktop processor series is
the next generation of 64-bit.
Quad-core processor built on 45-nanometer process
technology.
Throughout this presentation, the Intel® Core™ i5700 desktop processor series refers to the Intel®
Core™ i5-760, i5-750, and i5-750S processor.
4. History
The first Intel Core products was released in January
2006, called Core Solo and Core Duo, they were
only used in laptop computers, no desktop version.
Few months later in July of 2006 was presented
Core 2 Duo processor for desktop and laptop
computers. Not so often models were Core 2 Quad
and Core 2 Extreme. Quad was presented in August
2008 and Extreme in July 2007.

6. Specifications
Four cores
Cache: 8 MB
support DDR3 RAM
Turbo Boost is available. (Turbo boost is the technology that
automatically speeds up the processor when the PC needs
extra performance. This is done by "dyanmic overclocking" i.e.
increasing CPU clock-speed. This technology is available in
Core i5 processors and does not exist in any of the i3
processors. )
8. Operation
The
first step, fetch, involves retrieving
an instruction (which is represented by a
number or sequence of numbers) from
program memory.
The
location in program memory is
determined by a program counter (PC),
which stores a number that identifies the
current position in the program
9. Interfaces
System memory features include:
Data burst length (amount of data transferred during memory Read
and Write transactions ) of eight for all memory organization modes
64-bit wide channels
DDR3 I/O Voltage of 1.5 V
Maximum memory bandwidth of 10.6 GB/s in single-channel mode or
21 GB/s in dual-channel mode assuming DDR3 1333 MT/s
10. Interfaces … Cont,
1-Gb and 2-Gb DDR3 DRAM technologies are
supported.
Using 2-Gb device technologies, the largest memory
capacity possible is 16 GB for UDIMMs (assuming
Dual Channel Mode with a four dual rank unbuffered
DIMM memory configuration)
Up to 64 simultaneous open pages, 32 per channel
(assuming 8 ranks of 8 bank devices)
12. System Memory Organization
Modes
The
integrated memory controller (IMC)
supports two memory organization modes,
single-channel and dual-channel.
Depending
upon how the DIMM Modules are
populated in each memory channel, a
number of different configurations can exist.
13. System Memory Organization
Modes … Cont,
Single-Channel Mode
In this mode, all memory cycles are directed to a
single-channel. Single-channel mode is used when
either Channel A or Channel B DIMM connectors
are populated, but not both.
14. System Memory Organization
Modes … Cont,
Dual-Channel Mode
It is a feature that was created to reduce the potential
performance bottleneck that exists between the CPU and the
Memory Controller. It is enabled when a pair of same-size
memory modules are installed into matching banks, usually
color coded on the motherboard.
Based on our own experience, dual channel mode provides
about a 5-10% increase in performance in most games and
applications. Unless specifically required in rare cases,
combining memory modules of different sizes in the same
machine is compatible and will not affect system stability or
reliability in any way.
16. Processor Register
The
processor contains two sets of software
accessible registers:
1- Control registers
are I/O mapped into the processor I/O space
2- Internal configuration registers
