• 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

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.
Features Of Core I7 Processor-
All support 64-bit execution
Speed ranges from 2.66GHz to
Front Side Bus Speed include 2GHz,
4.8GHz or 6.4GHz
Support DDR3 main memory
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.
CPU PERFORMANCE BOOST VIA INTEL TURBO BOOST
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
o Intel Turbo Boost is activated when the OS requests the highest
processor performance state.
o Its frequency is maximum in Core i7 processors.
Mode Base Frequency Maximum
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
Improved Cache Latency with Smart L3
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
Optimized Multithreaded Performance through Hyper-
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.
Other Features are-
Enhanced Intel Speed Step Technology
during playing games
Over clocking capability
Streaming SIMD(single instruction,
multiple data) Instructions

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
• Four cores allows for handling software that
requires lots of computations.(High Quality
Games Like WatchDogs,GTA-4 etc.)
Disadvantages Of Core I7
• Very Costly
• Power Consumption is relatively high from other
• 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
Comparison Between Intel Core I3,Core I5 and Core I7 Processors-
Which one is the Best???
• In a test performed on a leaked hardware, the
core i7 outperformed the currently fastest core2
• It has got the advantages of high performance,
highly overclockable, quite cooling and power
• Some of the disadvantages include the
requirement of newer motherboards, sensitive to
• 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.
