Generally, laptops with i7 chips are better than ones with i3 and i5 chips. Of course, all the 3 chips must be in the same generation.
This is a question that has been asked many times, and the answer is not always clear. It really depends on your needs and what you are using your laptop for.
Generally speaking, an i7 laptop will be faster and have more features than an i3 or i5 model. However, the difference may not be as significant as you think. If you are only using your laptop for basic tasks such as browsing the internet, checking email, and watching videos, then an i3 or i5 model will be just fine.
If you need a laptop that can handle more intensive tasks such as graphics design or video editing, then an i7 model is a better option. It will be able to handle these tasks more efficiently and will provide a better overall experience.
Purpose and Performance
A laptop’s chip has a letter after the number which indicates a chip’s generation. The letter also has a meaning.
|G1-G7||Graphics level (processors with new integrated graphics technology only)|
|F||Requires discrete graphics|
|G||Includes discrete graphics on package|
|H||High performance optimized for mobile|
|HK||High performance optimized for mobile, unlocked|
|HQ||High performance optimized for mobile, quad core|
|U||Mobile power efficient|
|Y||Mobile extremely low power|
|X/XE||Unlocked, High End|
|B||Ball Grid Array (BGA)|
- The latest generation is the “K” series, which is meant for overclocking.
- The “U” series is for ultrabooks. They have low power consumption and are smaller in size.
- The “H” series is for high-performance laptops. They can handle more intense tasks than the U series but still, have low power consumption.
- The “HQ” series is a high-performance version of the H series.
- The “Y” series is the lowest power consumption series. They are meant for laptops that need to have a very long battery life such as 2-in-1s and Chromebooks.
Now, you know what each letter after the number means. You also know that each series is meant for a specific purpose. An i7 chip with Y suffix might not be stronger than an i5 with HQ suffix.
