The Basics of i3, i5, and i7 processors
Let us now understand the primary differences between the i3, i5, and i7 processors. These are the processors you usually deal with today.
- The i3 processors are the entry-level processors featuring dual cores. Thus, it entails having two processors on one chip. The i3 processors allow Hyper-Threading for efficient processing.
- The i5 processors come with two (Dual Core), as well as four cores (Quad Core). These processors come equipped with Intel’s Turbo-Boost technology that enables the cores to run faster than their operating frequency when required. This process is also known as overclocking.
- The i7 processors have two (Dual Core) or four cores (Quad Core) and come equipped with both Hyper-Threading and Turbo-Boost technology.
Thus, an initial glance at the three tiers shows that the i7 processor is better than i5, and the i5 processor is more efficient than the i3 processor.
Now, let us understand the numbering and the lettering that you come across with each processor.
The concept behind the numbering of the processors
For example, you have the Core i7-8650U processor and the Core i5-6200U processor. The first number represents the generation. Thus, the i7 processor belongs to the 8th generation and the i5 processor to the 6th generation in this example.
Naturally, the higher the number, the later is the generation.
The 6th generation processors came in the year 2015. Today, you have the 10th generation processors in the market, as well.
The next part of the name constitutes a three-digit number, 650 and 200, respectively.
It represents the SKU number (Stock Keeping Unit). Some people also refer to it as the model number.
Following the SKU number, you come across an alphabet. In our example, it is U. This alphabet distinguishes one processor from the others in the same generation.
Intel uses various suffixes for each generation. It represents the category of computer systems that the processor is ideally suited for. Here is what these suffixes denote.
|10th Generation i5 Processors|
|Y||Extremely low power||10310Y, 10210Y|
|G||Discrete Graphics on Package||1035G4, 1035G7, 1035G1,|
The suffix G is followed by numbers from 1 to 7, thereby indicating the level of graphics. The higher the number, the better is the graphics.
|9th Generation i5 processors|
|T||Power-optimized lifestyle||9400T, 9600T, 9500T, 9900T|
|H||High Performance Graphics||9300H, 9400H,|
|F||Requires Discrete Graphics||9900KF|
|8th Generation i5 processors|
|U||Ultra-low power||8265U, 8295U, 8296U|
|Y||Extremely low power||8200Y,|
|H||High Performance Graphics||8300H,|
|B||No description||8400B, 8500B|
|G||Discrete Graphics on Package||8305G|
We have concentrated on the 8th, 9th, and 10th generation i5 processors because we are now going to compare these three generations. It will help you to purchase the right one according to your requirements.
The difference between the 8th, 9th, and 10th generations
While you might not see much of a difference in the quality between the i5 8th generation and i5 9th generation processors, the 10th generation CPUs are a class apart.
The 10th generation CPU is an Ice lake CPU with a 10nm process, whereas the 8th and the 9th generation processors are the 14nm Sky Lake CPUs.
The Sky Lake Chip was introduced in 2015 as a 6th generation processor. Therefore, the 7th, 8th, and the 9th (all of which are Sky Lake CPUs with 14nm process) are refurbished versions of the 6th generation with some incremental advancements.
The 8th generation CPUs offer an entire range of processors, whereas the 9th generation offers only the high-end processors.
Though the 10th generation processors do not provide High-performance graphics, they are considerably faster than the earlier generations.
Let us now compare the 8th, 9th, and the 10th generation i5 CPUs and understand the difference.
Parameters to Compare
As we compare the CPUs of the 8th, 9th, and 10th generation, we shall look at the essential features alone without going into too much of the technical details. Here are the parameters that we shall compare.
Lithography is the semiconductor technology used for manufacturing an IC. It is denoted in nanometre (nm). It indicates the size of the features built on the semiconductor.
Cores, a hardware term, denotes the number of independent central processing units in a chip.

Comparison between i5 8th Generation and 9th Generation CPUs
The 10th Generation i5 processors
When it comes to comparing the 10th gen CPUs, they are a class apart. If you compare the basic features of the 9th generation and 10th generation CPUs, there is little to choose between the two.
However, when it comes to advanced features, the 10th generation CPUs are streets ahead.
Why prefer the 10th generation CPU?
Here are some reasons why the 10th generation i5 processors should be preferred to the earlier generations.
Highly advanced features
Integrated graphics have been around in CPUs right since the 2nd generation Sandy Bridge CPUs.
If that was a landmark introduction, the Thunderbolt 3 in the 10th generation chips is the next big integration.
Specific high-end laptops offered Thunderbolt 3 support using a Thunderbolt 3 controller.
However, the 10th generation chips get Thunderbolt 3 as a built-in feature. It could lead to PC makers saving costs, as well as increasing space inside the laptops.
Another positive aspect of the 10th generation CPUs is that all laptops will come with WiFi 6 compatibility.
Formerly, it was known as 802.11ax. The advantage is that it gives much higher speeds at 2.4 GHz while being capable of juggling multiple devices at the same time.
It is also compatible with 5 GHz operating frequency. Thus, people having a WiFi 6 router system at home will benefit tremendously.
Greater and faster memory
Gamers would love the 10th generation CPU
10th Generation or 8th/9th Generation – Which is preferable?
These five reasons should prove that the 10th generation chips are infinitely better than the previous generations. Hence, people wishing to switch over to the 10th gen CPUs can gladly do so.
However, does that make the present-day 8th and 9th generation chips obsolete?
No, you can still go for the 8th generation CPU. Here are some reasons to back our claim.
The 10th generation is faster, but the 8th gen chips are not very far behind
No one can deny that the 10th gen chips are faster than the present-day chips. However, the average user cannot distinguish between the two easily.
The AI performance is excellent, but it is an advantage in apps that support it.
A standard user who uses MS Office or the regular web browsers will not find much difference in the speed.
The number of cores and threads does not change as it did when Intel introduced the 8th generation CPUs. As compared to the 7th gen processors, the speed difference was immediately noticeable.
The 10th gen CPU offers better gaming experiences, but it is still far from being a gaming laptop
The 10th generation CPU-equipped systems will be expensive
We are in the initial days of the 10th generation CPUs. Therefore, the prices of these machines will be higher in comparison to the previous generation.
The provision of LPDDR4X RAM makes it more expensive. As the numbers of 10th gen laptops increase, the prices can go down.
At the same time, the 8th and 9th gen machines will start offering attractive discounts and incentives.
The 8th gen laptops are easier to get.
Generally, there are two types of CPU launches. At times, Intel launches a new generation that works seamlessly along with the existing ones.
Sometimes, you have launches that replace the current model overnight. Thus, people can find it confusing which one to opt for.
The 8th generation laptops are not only affordable but are easier to get when compared to the 10th gen laptops.
Which one should I purchase?
You have to consider many factors before selecting the right CPU. The speed of the processor is one of the crucial issues.
The graphics performance is another critical factor. The cost of the computer plays a deciding role. The standard user is the one who uses simple applications, including MS Office and so on. The 8th gen CPUs are the best as on date.
The 9th gen CPUs are also good, but they are comparatively high-end. The Y and U category of processors are not available in the 9th gen chips. These CPUs are the least expensive of all.
As far as the 10th gen CPUs are concerned, they are excellent for heavy-duty users video editing professionals and so on.
Depending on your utility, you can choose the right category of CPU.
