WHAT IS PROCESSOR?

A processor or microprocessor is a small chip that resides in computers and other electronic devices. Its basic job is to receive input and provide the appropriate output. While this may seem like a simple task, modern processors can handle trillions of calculations per second.

The central processor of a computer is also known as the CPU or “central processing unit”.

WHAT IS CORE?

Processing units that read and execute program instructions.

Processors have different cores:

Dual core has 2 cores

Quad core has 4 cores

THE BEST CPU MANUFACTURERS

CORE I3

The Core i3 is a dual-core computer processor, available for use in both desktop and laptop computers. It is one of three types of processors in the "i" series (also called the Intel Core family of processors).

The Core i3 processor is available in multiple speeds, ranging from 1.30 GHz up to 3.50 GHz, and features either 3MB or 4MB of cache. It utilizes either the LGA 1150 or LGA 1155 socket on a motherboard.

Power usage varies for the Core i3 processors:

CORE I5

A family of dual and quad core, 64-bit, x86 CPUs from Intel, introduced in 2009. The Core i5 chips are the midrange CPUs in the Core "i" line between the entry-level i3 and the high-performance i7 series.

Dual core CPU

Slightly higher clock speed than i3

Hyper Threading

Turbo Boost.

I3 VS. I5

Nehalem or Sandy Bridge Microarchitecture Based

Core i3 : This processor is considered to be the low

end, budget processor

Core i5 processor : This is considered the mid-range

and mainstream

I3 VS. I5(CONTINUE…)

Their relative levels of processing power are also signified by their Intel Processor Star Ratings, which are based on a collection of criteria involving their number of cores, clock speed (in GHz), size of cache, as well as some new Intel technologies like Turbo Boost and Hyper Threading.

Core i3s are rated with three stars, i5s have four

stars, and i7s have five.

We will compare i3, i5 according to :

Number of Cores

Cache Sizes

Hyper Threading

Intel Turbo Boost Technology

I3 VS. I5(CONTINUE…)

Number of Cores:

Core i3 : all of them are 2 cores

Core i5 : either 2 cores or 4 cores

Cache Size :

Core i3 : All of them have 3 MB Cache

Core i5 : All of them have 6 MB Cache(Except for some)

HYPER-THREADING

Intel has introduced a technology called Hyper-Threading. This enables a single

core to serve multiple threads.

The main function of hyper-threading is to decrease the number of dependent

instructions on the pipeline.

The number of threads is double the number of cores :

Core i3 : 2 Cores 4 Threads

Core i5 : Either 2 Cores That support Hyper Threading 4 or 6 Threads

INTEL TURBO BOOST TECHNOLOGY

The Intel Turbo Boost Technology allows a processor to dynamically increase its clock speed whenever the need arises. The maximum amount that Turbo Boost can raise clocks peed at any given time is dependent on the number of active cores, the estimated current consumption, the estimated power consumption, and the processor temperature.

None of the Core i3 CPUs have Turbo Boost

All Core i5 and Core i7 are equipped with Turbo Boost Technology
