Which Is Best Processor for You?? I3 , I5 OR I7

Which Is Best Processor for You?? I3 , I5 OR I7 ????

If you are thinking whether you need a Core i3, i5 or i7 processor for your next upgrade or brand new PC, take a seat and we will explain the differences to help you make the right choice

The common rule is that the more power (and more expensive) processors you go from i3 to i5 and then to i7.

These days, even the basic dual-core processor is sufficient for unnecessary tasks. This means that whether you are buying a laptop or a PC, Windows should also run well on the budget model.

 Non-demanding tasks are all about everything that doesn't include gaming and video editing (if you want to do this, see our guide for the best processor for gaming and video editing).

By default, if you just want to do all the normal work with their computer - email, web browsing, YouTube, editing and sharing photos, Microsoft Office - is a basic processor.

If you are reading this during the process of selecting a budget laptop, find out that one of the most influential components for overall responsibility is a hard drive. If you can get ssd instead of traditional hard disk for a similar price, the core i5 processor for i3 is worth sacrificing.

How many cores do I need?

You rarely see single-core processors and you should avoid them at all costs. More core means more

Efficiency, plus the ability to run multiple programs at once.

Many programs can also avail multiple

cores, even if you are only walking

In one program, you should see the improvement

Compared to running operations on a computer with fewer cores than cpus.


However, do not just look at the number of cores. Intel processors often support hyper-threading, which effectively allows them to handle twice as much as the number of threads and is slightly doubling even though the number of cores is almost double.

In computing language, thread is a sequence of programmable instructions that the CPU has to process. If the CPU has one core, it can process the same thread at once, so it can do the same thing at the same time. In fact, it is more complex than this, but the purpose here is to keep it simple and understandable.

Therefore, the dual-core CPU can process two threads at the same time, quad-core four threads at the same time. It is twice as much as the work in the same time period.


Hyper-threading is a clever way to allow the same core to handle multiple threads.

The core with hyper-threading can process two threads per i3 core, which means that a total of four threads can run simultaneously. The current core of desktop processors is not hyper-threading in the i5 range so it can process only four cores. i7 processors have, so they can process up to eight threads at once. Connect it to 8MB cache and turbo boost (below), and you can see why the core i7 chips are more powerful than i5 or i3.

Turbo Boost

The turbo boost is Intel's marketing name for technology, which allows the processor to increase its core clock speed whenever it needs. Turbo boost can speed up the clock depends on the number of active cores, estimated current usage, estimated power consumption and processor temperature.

The Core i3 processors do not have turbo boost, but do i5 and i7s. This means that core i3 chips have a very high 'base' clock speed.

If the processor ends with the model K, it means it is unlocked and can be 'overclocked'. This means you can force the CPU to run at a faster speed than its base speed for better performance.

The quad-core processor can have a similar performance overall.


8th generation Intel Core Processors

The current range of 8th-generation Intel Core processors for desktopis very large, with several different processors for each i3, i5 and i7 categories. It has codename Coffee Lake.

The most powerful is 8700k, the top of the pile for the i7. The processor has a base clock speed of 6 cores / 12 threads, 3.7 GHz with max turbo frequency of 4.7 GHz and 12MB of cash.

The least powerful is the i3-8100, which has 4 core /4 threads, with 3.6 GHz (sadly not turbo boost) and 6MB cache.

What about graphics?

Many Intel processors have GPU - graphics chip - made in CPU.

These graphics are sufficient for everyday tasks, but if you are planning to do any gaming or video editing, you would like to check the stand alone graphics card for your system.

What is i9?

The more powerful range of the processor is available, which is intel core i9.

This is not really a target for customers, and when you can put it on your PC (your motherboard can take it) it is usually reserved for software, such as running a server.


What is best: i3, i5 or i7?

You will be forgiven for being confused at this stage. It is not possible to look at the specifications of the processor and decide what is fast for you.

That is why we review every laptop and PC. This tests not only CPU but also the entire system function. It is a processor plus memory (RAM) and hard drive - along with a graphics card - which determines how fast a PC or laptop is.

Generally, which is the best for each processor type is as follows:

  • Intel Core i3: Default users. Economic selection. It's good to browse the web, use Microsoft Office, make video calls, and social networking. Not for gamers or professionals.

  • Intel Core i5: Interim users. who want a balance between performance and value. If you buy a G processor or Q processor with dedicated graphics processor, it's good for gaming.

  • Intel Core i7: Power users. You open some windows at once, you run apps that require a lot of horsepower, and you don't like to wait for anything to be loaded.

Similarly, if you are going to run extremely demanding software such as video editing or encoding programs, you want to go to Core i7. But for most people, it's overkill.

If you're after the best battery life, find the model number in the US or the processor with Y. It uses minimal power, but also provides slower performance.

Finally, don't forget AMD. The new range of Ryzen processors for Pc is of great value and the Ryzen 5 chips are better priced than Intel's Core i5.
