when you want to buy a laptop or a computer. Much manufacturing companies provide you with the best-of-best deal. Buyer is very confused which one buy or not. Find out first which chipset is best for your requirements? Let’s compare which best Intel i3, i5, and i7 processors.


Hyper-Threading is Intel’s technology Windows into thinking that each physical processor core is, in fact, two virtual (logical) cores. The operating system can then share processing tasks between these virtual cores in order to help certain applications run more quickly and to maintain system performance when more than one application is running at once.

Cache memory

A processor’s performance isn’t only determined by clock speed and number of cores, though. Other factors such as cache memory size also play a part. When a CPU finds it is using the same data over and over, it stores that data in its cache. Cache is even faster than RAM because it’s part of the processor itself.
Here, bigger is better. Core i3 chips have 3- or 4MB, while i5s have 6MB and the Core i7s have 8MB.

Turbo Boost

Turbo Boost is Intel’s marketing name for the technology that allows a processor to increase its core clock speed whenever the need arises. The maximum amount that Turbo Boost can raise clock speed depends on the number of active cores, the estimated current consumption, the estimated power consumption, and the processor temperature.

Core i3 processors don’t have Turbo Boost, but i5 and i7s do. It means that Core i3 chips tend to have quite high ‘base’ clock speeds. If a processor model ends with a K, it means it is unlocked and can be ‘overclocked’. This means you can force the CPU to run at a higher speed than its base speed all the time for better performance.


A core can be thought of as in individual processor. A dual-core processor, therefore, has two internal processors, a quad-core model has four. More cores are useful for multi-tasking; for example, you can run two applications at the same time, each one having access to its own dedicated processor.

More cores are also useful for multi-threaded applications, such as video editing. With these types of applications, they can use multiple cores to improve performance. Single-threaded applications can only use a single core leaving any others idle. Core i3 processors have two cores, Core i5 CPUs have four and Core i7 models also have four. Some Core i7 Extreme processors have six or eight cores. Generally speaking, we find that most applications can’t take full advantage of six or eight cores, so the performance boost from extra cores isn’t as great.

Which is best for you

Core i3: laptop for everyday computing tasks like web browsing, video streaming and office-type work, the Core i3 is great. Its dual-core means regular tasks will be slicker and easier. Intel’s Hyper-Threading technology also makes more efficient use of its power.

The most budget-friendly laptops usually run on a Core i3. However, if you need to run demanding creative or scientific programs this isn’t the one for you.

Core i3 Features
Multiple webpage tabs should run smoothly
Work on reports and essays in Word, or in basic spreadsheets in Excel
Stream movies and TV shows from Netflix
Listen to your favourite playlists and albums on Spotify
Multi-task efficiently with Intel Hyper-Threading technology

Core i5 : It’s perfect for Excel or PowerPoint while streaming Spotify and browsing Facebook and scanning web pages all at the same time.

Similarly, designers and photographers who work in Adobe Photoshop and Illustrator will be well catered for – provided the laptop also has plenty of RAM and good built-in graphics.

Core i5 Features
Multi-task streaming music or video, with Facebook and web pages, open too
Work on complicated tasks like rendering a big Excel file
Smoothly edit photos in Photoshop and sketch out graphics in Illustrator
Play intensive PC games with the right i5 – find out more about Intel processors for gaming
Benefit from faster-repeated tasks thanks to the large cache size
Stream from multiple sites at the same time

Core i7
Core i7 made for video & advanced video editors, 3D modelling, software designers and gamers. Core i7 With 4 proper cores, and technology to create another 4 virtual cores, it has enough power for the most demanding tasks.

Core i7 Features : Encode video more efficiently (encoding processes every frame in your video and can take hours – you can cut a few seconds off every minute)
Work smoothly in 3D modelling programs like AutoCAD
Smoothly edit photos in Photoshop and sketch out graphics in Illustrator
Crunch numbers on spreadsheets more efficiently
Enjoy working more efficiently when using demanding creative programs like InDesign – each core uses 2 ‘threads’ rather than 1 thanks to Intel Hyper-Threading technology
Benefit from faster-repeated tasks thanks to the large cache size
