What you need to know about Intel cores i3, i5, i7, and i9

When someone is dwelling in the computer world first thing that person gets confused with is the cores of a computer. There are many processor companies with new startups coming into industries.

This article will talk about Intel cores, their series, and how these cores compare with each other. When we are talking about Intel cores there are i3, i5 and i7 are widespread names, and i9 is a new addition to the series. Cores are judged on their performance, Cache Size, multi-tasking, and threading,

i3 i5 i7

Cores are the branding names of intel and they are actually related to processors. A processor in a computer is the main hub and they perform every function. The processor takes information then acts on it and refers the command to the relevant part.

Cores

We have established cores are processors but what exactly are cores and how Intel name them. Does i3 have 3 cores or 3 GHz? No with Intel it’s different and they want to mix things up. i3 have 2 cores generally in some exceptions there is only 1 core. i5 is quad-core which means it has 4 cores so better performance yeah that’s complicated, the answer is no. Finally, we have i7 which is also quad-core but in some i7 processors, there are 6 cores. YIPPEE! Every core can perform one function at a time. So the rule of thumb is more cores better efficiency. But when we are talking about processors there are some more components to consider too before making a general comment.

Cache Size

What is cache? Do we speak it as cash or we can buy things with it and answer to this, sadly, is no too. Cache size is the memory part of the processor. Cache stores a very small amount of information compared to RAM. But it is very quick because it is a part of the processor itself. Because of cache computer can perform tasks instantly and it does not have to get information from RAM. Cache stores small but a piece of important information which user is expected to use immediately. With ascending cores the cache size also improves. i3 has less cache memory usually of 2-4 MB which is less than both i5 and i7. i5 has a memory of 4-8MB which is significantly higher than i3. Lastly, i7 has a cache memory of 8-12MB. This round is also won by i7.

Hyperthreading

Hyperthreading is an efficient tool of cores. It refers to improving the capacity of each core by double. So during stressful work cores can improve their efficiency and do more in less time. Think this like if one core is one car lane then with hyperthreading that core will become a two-way lane so more information can be passed and more work can be done. Now intel used its magic they have included hyperthreading in the i3 core so it means i3’s 2 core will become 4 core. But coming to i5 it is bad news guys because i5’s core will not become double when the computer is doing extra work. When coming to i7, hyperthreading is present and its cores will also get double so better performance and efficiency. So this round is also won by i7.

Turbo Boost

Turbo boost also improves the efficiency of the processor but it is very different than hyperthreading. In hyperthreading, it is more like doing double the work but for turbo boost, the capacity of work improves for one task. If you are playing a heavy game then the processor will enable turbo boost and your task will be done a lot smoother. Turbo boost is done by increasing clock speed and performance improves a lot from the base level. If the processor model level ends with K then it means it is unlocked can be forced to increase its speed but using this for a long time will damage the processor so not advisable. Only i5 and i7 are enabled turbo boost sadly i3 can not be turbo boost.

i7

Prices

For most users, price is a determining factor while buying the computer and processor. i7 is expensive than i5 and i3. i3 is the least expensive compared to either of them.

i5

Conclusion

i3 is for basic users who do not have many usages of light web surfing and for doing a light task, and it is a very budget-friendly computer that would not put a dent in your pocket. i5 is for intermediary users who want performance but want to stay within budget. With a gaming card and processor, its performance can be increased. i7 is for expert and heavy users who have to do a lot of multitasking and do heavy processor work. The conclusion is it really depends on your workload and patience to decide which processor is best for you.
