Differences Between core i3 i5 i7 Intel Chips

The differences between core i3 i5 i7 Intel’s Processors. I’m sure most of you have come across the name Intel numerous times or at a point in time. INTEL a multinational company known for production of processors that powers our computers and laptops devices only to mention a few. INT-el short for Integrated Electronics has been in the system for a really long while now amongst peers like AMD. As well as others, bringing out the best CPU’s a computer device can ever have.

But the fun fact is Intel actually made their first debut there around 2006. Where after a long run with developing the Pentium series they replaced with Intel Core. Where the core actually was the first brand of its kind. It was followed up by Intel core 2 duo and then quad core chips. Then momentarily the popular brand sprouted , The Intel core ‘ i ‘ even though it follows the same implementation as either core duo or quad core its architecture and processing power and indeed a remarkable experience.

WHY i3, i5, i7 ?

But the confusion is where the numbers come in. Why i3 i5 i7? Many believe perhaps initially Intel tried to just make the first ‘i’ series but couldn’t name it i2. Maybe because it would conflict with the core 2 so then it landed with i3. But the trend seemed to have a pattern continuing from i3 to i5 then i7 and now a latest design i9 has been released. Or perhaps they just came up with a name to get consumers talking . Well who knows.


A lot of people even with their IT knowledge find it difficult explaining the difference between these core i series. Let me explain in simple terms. Remember this is only limited to core i3, i5 and i7 models as there other brands and models still produced by intel. There are actually four main models released by Intel. Being i3, i5, i7 and i9. each of them having numerous specifications but the simple difference says i5 is superior to i3 and as i7 is to i5 and it follows like that. There is more to it.

The trouble is knowing what specification each series has as things go a little deeper than a mere 3 or 5 or 7 attached to the i. Typically, the Core i3 series has only dual-core processors at the start of production. While the Core i5 and Core i7 series have both dual-core and quad-core processors with preceding more power. As the names suggest you should know by now that quad core is more powerful than the dual cores but even still things go a little deeper.


Periodically Intel releases a class of chip-sets, called generations. The latest one at the time of writing this article in 2021 is the 10th-generation series with the code name “Ice Lake,” Each Core i3, Core i5, and Core i7 series of processors has its own generation of family. You can tell which generation a processor belongs to by the first digit in the preceding four-digit model name. For example, the Intel Core i3-10110 belongs to the 10th generation.

Another point to note is; The other three digits are Intel’s assessment of how the processor compares to others in its own line. Or simply how powerful it is compared with others in the same family. For example, an Intel Core i3-10110U is superior to the Core i3-8145U because of the generation but comparing core i3 10110 to core i3 10650 then the latter is far more powerful. Most times even if there are not in the same generation the preceding 3 digits being higher means it is much powerful in some aspect.

For example an Intel Core i3-8500 is superior to the Core i3-10110. This is because 500 is far higher than 110 and probably released at a recent date regardless of the generation. I figured you might want to know if the letters at the end also mean something. The answer is YES The Letters at the end of each model name tells a great deal about the model. Much details about it would be explained here; DO THE NUMBERS AFTER AN INTEL CORE PROCESSOR MATTER?

That explains a lot. Now lets go back to the big family.

Core i3:

Intel Core i3 processors in general, have lower core counts than higher-grade CPU’s. Actually Core i3’s started with only dual-core processors. But for recent generations integrated into desktops, that core count has gone up to four. Core i3 processors also have lower cache sizes (onboard memory) meaning they handle less RAM than other Core processors and have varying clock speeds. At this writing, the ninth-generation, Core i3 desktop processors has a clock speed peak of 4.6 GHz; however, that’s only the higher-end Core i3-10320K

Core i5:

An i5 typically lacks Hyper-Threading, but it has more cores (currently, six, rather than four) than Core i3. The i5 parts also generally have higher clock speeds, a larger cache, and can handle more memory. The integrated graphics are also a bit better.There are new Core i5 processors with Hyper-Threading on laptops, but not desktop

Core i7:

Core i7 CPU’s These processors have higher core counts up to eight in the ninth generation, a larger cache, and a boost in graphics performance Core i7 CPU’s had Hyper-Threading on desktops allowing it to boost performance but the more recent generations do not, they have the same memory capacity as the Core i5’s but that could change in the future. This table summarizes the details.

To Conclude, this is what these processor types are best for;

  • Intel Core i3: Basic users. Economic choice. Good for browsing the web, using Microsoft Office, making video calls, and social networking. Not recommended for games or professionals. even though higher generations can be suitable.


  • Intel Core i5: Intermediate users. Those who want balance between performance and price. Good for gaming if you buy a G processor or a Q processor with a dedicated graphics processor to boost gaming and professional tools experience like Video and animations.


  • Intel Core i7: Power users. perfect for multi-tasking with several windows open at the same time,running apps that require a lot of power typically its the best to go for comparing to price if you do not want the latest i9 model.

Hope This Article was clear enough and now you do not have a problem deciding which processor to choose.
