Intel i7 and i5 Processors

“Technology must be like oxygen: Ubiquitous, Necessary, and Invisible”

In this article of SAIKISITE, I will be comparing the Intel I7 and I5 processors. But before starting that, let’s have a general idea about the Processors.


I believe most of the readers, reading the article, may fall in the category of a college student, and as I believe, Laptop is a very essential part of our college life. Not only it helps in our academics but also helps us in exploring the tech world. Also, it is helpful in learning different kinds of programming languages , web designing , technical aspects and so on. But the real deal is to select the processor that will be best suited for your laptop or desktop. Processors can be considered as the most vital aspects of the personal computers. With it, the performance of our personal computer can either get elevated or declined if a wise decision isn’t made in the direction of the processor selection. As in this era of technology, we find that with every second some new discovery has been made, some new improvements been done on the prototype, so it’s essential for us, the common people, to have a slight insight in today’s tech. Before making a comparison I would like my readers to be familiar with the “Processors”.



Processors of our computer can be considered as the soul of the system. The entire framework of our laptop or desktop depends on them. Taking in account the present scenario, we have a wide range of processors in front of us. Not only that, there’s also a huge list of different kind of laptops and desktops present in today’s tech market. Now the price of the personal computer is entirely affected by the choice of the processor we want to use in our system. Most of you may think that what’s a great deal about making a choice for a simple processor? but let me tell you guys, it’s just not about a simple processor but the advantages and disadvantages that it brings with itself.

The most widely used processor in current time is and has been manufactured by Intel. Let’s not go deep in the history of its origin but let’s have a slight idea about it. The two most popular CPU processors are Intel i7 and i5 processors 6th Generation. When you go for purchasing any of the two, you will find a slight variance in its price but what you don’t notice that this little variance has a great deal of impact on personal computers performance.

Let’s begin with its comparison.

“Technology, like art, is a soaring exercise of the human imagination.”

Marketing Prices with general specs


Talking about prices, we see, i5 processors are less expensive than i7 processors. But if we see the growing use of laptops and desktop, keeping in mind that i7 are way more compatible than i5 processors. i7 processors are best suited for multitasking, high-end gaming, multi-threading and multi-media tasks. The i7 processor can be used efficiently for scientific work whereas i5 will lag this ability. In general, I can say that i7 processors are for those users that have a constant complaint for their system’s running “SLOW”.

Core Of Processors


If we talk about CPU performance, i7 provides faster performance when compared to i5 processors. A majority of i7 CPU processors that are used nowadays are mainly quad-core while i5 are mainly Dual-core. But that’s not just the case, users can even choose a hexa-core i7 processor at a comparatively high rate. Hexa-core i7 processors are provided in extreme edition models whereas for i5 there is no scope for hexa-core, right now. As we talk about the core of the processor’s, let me make you all aware of the processors that were used in the past. Older generation computers had Nehalem & Westmere and Sandy (codename for an Intel processor micro-architecture) which had low-performance issues. Ivy Bridge and Haswell’s CPU are one of the latest technologies incorporated in personal computers. Ivy processors are present in budget PC while Haswell’s processor are provided in mostly all new PC’s.

Integrated Graphics


Intel HD graphics were introduced by the Westmere generation of core processors. These were the pre-installed graphics on the core itself. In Early years, they were built on the motherboard chipsets which had a declining impact on CPUs performance. Intel HD graphics were incorporated in Sandy Bridge processors and Ivy Bridge processors under the name DX10 2000/3000 and DX11 2500/4000 respectively. But like any other feature, this feature also had its advancement. Now in Haswell’s processor either update HD graphics are present or the latest, Iris Pro. If you purchase an extreme edition model, it will generally have Iris pro which is way more compatible for i7 than i5. The advantages of storing the Integrated graphics to core from the motherboard is that it saves a considerable amount of power.

Turbo Boost


Turbo boost can be understood as a feature that makes your processor run faster. How? Let’s read: It allows personal computers to run faster than their default base clock speed when only one or two processors work is/are needed and this feature comes in handy while single threaded tasks. Both i7 and i5 use this feature but only i7 achieve a higher base clock speed.

Hyper-Threading (Hybrid Technology)


First, let’s have a basic idea of multithreading. The Multi-thread situation is when a user runs several programs at the same time. Generally, it would overload the processor but that flaw has been overcome by Hyper-threading technology. It’s basically a technology (multithreading technology) that makes your Operating System think that the processor which is being used has more core than there are actually physically present. And obviously, it increases the performance of multithreaded tasks. If you have a 6 core CPU, hyper threading will handle it like 12 stream one; 4 core will be treated as 8 stream and dual core like 4 stream. The major drawback comes in i5 where dual core acts like four core one but if someone has four true cores, hyper-threading will not be available in their system. Readers let me bring it to your knowledge that this technology has some drawbacks also. One such drawback is other activities/tasks take advantage of hyper threading like web surfing, it automatically starts loading flash content, GIF, images simultaneously.

“Technology is a Useful Servant, But a Dangerous Master”



Intel i7 processors have large cache size as compared to Intel i5 processors. Large cache size helps processor deal with repetitive tasks faster. For example: If you are using Spreadsheets, with high cache size, CPU wouldn’t have to reload the framework where numbers are stored. The information will be directly stored in cache and instantaneously be used in the calculations. That’s one of the advantages of having a greater cache size. Cache sizes also play a key role in multitasking. Currently, i7 has cache size 4 MB to 8 MB while i5 processor has cache size from 3 MB to 6 MB of L3 cache.

With the above comparison, I can conclude that i7 processors are best suited for high-end users who are very keen to learn something new and advanced in the tech world but if your usage of personal computer is limited like any other user, then you may opt for i5 processors also.
