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.

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

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

3.33GHz

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 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

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.

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.

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 graphics.

• Four cores allows for handling software that requires lots of computations.(High Quality Games Like WatchDogs,GTA-4 etc.)

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.

Time Spent

Comparison Between Intel Core I3,Core I5 and Core I7 Processors-

Which one is the Best???

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.
