The document discusses the Intel Core i7 processor. It describes the Core i7 as Intel's first processor using the Nehalem microarchitecture, featuring faster and more intelligent multi-core technology. Key features of the Core i7 include support for 64-bit processing, front side bus speeds of 2-6.4GHz, compatibility with DDR3 memory, and Intel Turbo Boost Technology to accelerate performance. The Core i7 also utilizes a shared L3 cache up to 12MB in size and Hyper-Threading to improve multithreaded performance. While powerful, Core i7 processors are also costly and have higher power consumption than other processors.

2.  Introduction
• A processor is the logic circuitry that responds to
and processes the basic instructions that drive a
computer or (simply the brain of the computer).
The term processor has generally replaced the term
central processing unit (CPU).
• The processor in a personal computer or embedded
in small devices is often called a microprocessor.
• An Intel Corei7 is an Intel proprietary processor that
is built on the framework of multiprocessor
architecture.

3.  List of Intel Processors
 Enhanced Pentium M based
 Core Duo
 Core Solo
 64 bit Core micro architecture based
 Core 2 Duo
 Core 2 Solo
 Core 2 Quad
Core 2 Extreme
 Nehalem micro architecture based
 Core i3
 Core i5
 Core i7

4.  What is Intel Core I7 Processor?
Core i7 is first processor using Nehalem Micro-
architecture and a processor with faster, intelligent,
multi-core technology .
Examples are- i7-5550u, i7-5557u, i7-5500u etc.

5.  Features Of Core I7 Processor-
All support 64-bit execution
Speed ranges from 2.66GHz to
3.33GHz
Front Side Bus Speed include 2GHz,
4.8GHz or 6.4GHz
Support DDR3 main memory

6.  Higher-Performance Multiprocessor Systems with QPI-
QPI(Quick Path Interconnect) is the new point-to-point interconnect
for connecting a CPU to either a chipset or another CPU. It provides
up to 25.6 GB/s of total bidirectional data throughput per link. It
incorporates distributed shared memory architecture.

7.  CPU PERFORMANCE BOOST VIA INTEL TURBO BOOST
TECHNOLOGY-
o Intel Turbo Boost Technology accelerates processor and
graphics performance for peak loads, automatically allowing
processor cores to run faster than the rated operating frequency
if they’re operating below power, current, and temperature
specification limits.
o Intel Turbo Boost is activated when the OS requests the highest
processor performance state.
o Its frequency is maximum in Core i7 processors.
Number of
Active Cores
Mode Base Frequency Maximum
Turbo Boost
Frequency
4 Quad-Core 1.73 GHz 2.0 GHz
2 Dual-Core 1.73 GHz 2.8 GHz
1 Single-Core 1.73 GHz 3.06 GHz

8.  Improved Cache Latency with Smart L3
Cache-
Cache is a block of high-speed memory for temporary data
storage located on the same silicon die as the CPU.
The Core i7 family of processors features an inclusive
shared L3 cache that can be up to 12 MB in size.
Figure-The inclusive shared L3 cache in the Core i7 processors
offers better cache latency for increased
performance.

9.  Optimized Multithreaded Performance through Hyper-
Threading-
Hyper-threading exposes a single physical processing core
as two logical cores to allow them to share resources
between execution threads and therefore increase the
system efficiency. It uses processor resources more
efficiently, enabling multiple threads to run on each core.
Figure . Hyper-threading allows simultaneous execution of
two execution threads on the same physical CPU core.

10. Other Features are-
 Enhanced Intel Speed Step Technology
during playing games
 Over clocking capability
 Streaming SIMD(single instruction,
multiple data) Instructions

12.  Advantages of Core I7 Processor-
• Big cache size
• Very fast
• Better cooling system
• Provide High data visualisation technology to
users to view high quality images and video
graphics.
• Four cores allows for handling software that
requires lots of computations.(High Quality
Games Like WatchDogs,GTA-4 etc.)

13.  Disadvantages Of Core I7
Processors
• Very Costly
• Power Consumption is relatively high from other
processors
• Will only work with DDR3 Memory, meaning for
people upgrading from DDR2 will have to get a
whole new motherboard
• Not a whole lot of software will require multi-
threading, meaning for the average person - there
won't be much of a performance gain from a dual
core.

14. Time Spent
 Comparison Between Intel Core I3,Core I5 and Core I7 Processors-
Which one is the Best???

15. Conclusion
• In a test performed on a leaked hardware, the
core i7 outperformed the currently fastest core2
extreme processor.
• It has got the advantages of high performance,
highly overclockable, quite cooling and power
efficient.
• Some of the disadvantages include the
requirement of newer motherboards, sensitive to
higher voltage.
• The technology keeps on improving as the need
for faster and high end applications increases.
The i9 core version is about to be released soon.
