Intel core i3 vs. i5 vs. i7 vs. i9
What is the difference?

To begin with, many are familiar with Intel Celeron and Intel Pentium processors like P2, P3, & P4. Later, dual-core processors and finally Intel core i series. Personal Computers have evolved over the years, invention and innovation have skyrocketed and man’s quest to evolve has no limit. Today, let’s look into some of these innovations in PC over the years and the tasks designed for each.  

Intel’s first Core processors made their debut in 2006. At this point, children born in the same year are almost old enough to drink. Over a dozen generations of Intel Core i3, Core i5, and Core i7 CPUs have come and gone since then but most consumers are still asking the same kinds of questions. Intel Core i3, Core i5 or Core i7? What’s the difference? Is it worth it to own a CPU with more cores, a faster clock speed or advanced features like hyper-threading?  

Core i3, Core i5, Core i7 — the difference in a nutshell
If you want to boil things down to something plain and simple, then generally speaking, “most” Core i7 CPUs are better than most Core i5 CPUs, which are in turn better than most Core i3 CPUs.    

*An Intel Core i3 to provide adequate performance for basic tasks.
*An Intel Core i5 to provide good performance for most tasks.
*An Intel Core i7 to provide great performance for the most demanding of tasks.  

Key Difference between Intel Core i5 and i7
Core i5 Processor is dual-core or quad-core, whereas Core i7 processor is dual-core, quad-core, and hex-core processor architectures. Hyper-Threading is not possible in Core i5 processors, but it is possible in Core i7 processors.

My advice
Don’t make this mistake when buying a laptop.
Listen, you have the core i3, i5, i7 & i9. What to look out for when buying a laptop?
Always look for the last letter in the CPU. Now, if it ends with a U e.g 10210U is meant for lower tasks like surfing the web, or using Ms-Word, or Ms-Excel.  

If it ends with a P like 12340P, it’s slightly meant for Powerful tasks like using Photoshop and basic programming. If it ends with H like 10300H, it’s meant for High-performance tasks like video editing, graphic design, and gaming.
