Hey there Brainy here and today I’m coming at you with a very interesting question.

The Question is “What’s the big difference between i3, i5 and i7.

For those who don’t really understand this video is for you so stay tuned and let’s

So first off I need to explain what i3, i5, and i7 are, more specifically what does a

A computer processor, which is commonly referred to as a CPU, is responsible for fetching,

decoding, executing and writing back information that it receives from the coding that is present

A CPU is the main unit in a computer that allows the computer to function using programmable

In layman terms a computers processor kind of manages all the activities that go on within

Now, Let’s get into the actual question at hand.

What ‘s the big difference between i3, i5 and i7.

Intel Core i3, Core i5, and Core i7 CPUs have been around since 2011.

Each year Intel launches new chips based on newer technology, but keeps the same names

In general, Core i3 chips are found in cheaper or budget PCs and laptops, while the mainstream

Core i7 CPUs are typically reserved for - and found in - high-end, expensive laptops and

Their relative levels of processing power are based on a collection of criteria involving

their number of cores, clock speed (in GHz), size of cache, as well as Intel technologies

And I probably just said a few things you may not have understood.

Cores, Clock Speed, Cache, Turbo Boost and Hyperthreading.

All CPUs have one or more cores, with each core being a processor itself.

Most commonly an Intel Core processor will have two physical cores (dual-core) and also

two virtual cores (which Intel calls Hyper-Threading).

A processor core is a processing unit which reads instructions to perform specific actions.

Instructions are chained together so that, when run in real time, they make up your computer

Literally everything you do on your computer has to be processed by your processor.

So basically the more cores that a Processor has the better it runs, and physical processor

cores are usually more powerful then virtual ones.

A cache (pronounced CASH) is a place to store something temporarily in a computing environment.

In computing, active data is often cached to shorten data access times, reduce latency

Because almost all application workload is dependent upon I/O operations, caching is

For example, Web browsers such as Internet Explorer, Firefox, Safari and Chrome use a

browser cache to improve performance for frequently accessed webpages.

Clock Speed is the speed at which a microprocessor executes instructions.

Every computer contains an internal clock that regulates the rate at which instructions

are executed and synchronizes all the various computer components.

The CPU requires a fixed number of clock ticks (or clock cycles) to execute each instruction.

The faster the clock, the more instructions the CPU can execute per second.

Clock speeds are expressed in megahertz (MHz) or gigahertz ((GHz).

The internal architecture of a CPU has as much to do with a CPU's performance as the

clock speed, so two CPUs with the same clock speed will not necessarily perform equally.

Normally the computer processor in your laptop or desktop has a standard clock speed which

partially determines how quickly it performs.

While the processor might lower its clock speed at times in order to conserve power,

the clock speed which is stated when you buy the computer is the fastest clock speed you’ll

Intel’s new Core i5 and Core i7 processors have a feature called Turbo Boost which has

the ability to dynamically scale up the clock speed of a processor depending on the thermal

Intel Turbo Boost monitors the current usage of a Core i5 or i7 processor to determine

how close the processor is to the maximum thermal design power, or TDP.

The TDP is the maximum amount of power the processor is supposed to use.

If the Core i5 or i7 processor sees that it is operating well within limits, Turbo Boost

Turbo Boost is a dynamic feature so There is no set-in-stone speed which the Core i5

or i7 processor will reach when in Turbo Boost.

Turbo Boost operates in 133Mhz increments and will scale up until it either reaches

the maximum Turbo Boost allowed or the processor comes close to its maximum TDP.

Hyper-Threading is a technology used by some Intel processors that allows a single processor

to act like two separate processors to the operating system and the program s that use

With Hyper-Threading, a processor's "core" processor can execute two threads of instructions

Having two streams of execution units to work on allows more work to be done by the processor

So that’s the most you would need to know about processors right now.

So in terms of which is best there is no right or wrong answer.

If you are looking to do extreme gaming and use your pc for tough tasks an i7 processor

If you are looking to do basic stuff then an i3 processor would be best.

And an i5 processor falls somewhere in the middle.

But remember that the overall performance of your pc does not only depend on your processor.

Other factors such as RAM, Power Supply, Your Motherboard and the Disk space also come into
