I know that if you have come to blog post to know the battle between intel core i5 10th gen vs i7 8th gen processors and which out of them is better than other.

And I promise you that if you will read this article fully then all your doubts regarding this topic would be cleared. So, let’s now jump to the main topic.

Intel core i5 10th gen vs i7 8th gen: Which to buy for your pc (with benchmarks)

Intel comes with 4 types of CPU which are i3, i5, i7 and i9. Intel made this classification on the basis of its power and performance.

However, this also makes user confused that which CPU his/her should buy in order to do gaming, editing or programming.

If you want to buy a gaming laptop under 1 lakh rupees then here is a guide and review for it.

And that is the reason why I have come up with this post to tell you which one of the two processors you should buy.

Intel core 10th gen > 8th gen. Mystery unwrapped?

Now, first let’s talk about what normal people who have very less knowledge of computer hardware thinks like when it comes to buying a processor for your PC.

He/she would 10th generation CPU are much more powerful that 8th generation ones because 10th gen is made as per recent technology.

But, Do you think that all the 10th gen CPU of intel gives much better performance than 8th gen CPUs?

Let’s tell the answer of this question which is absolute no. There are two main reasons for it:
1. Core count matching in both the CPUs
2. Same architecture (14 nm) both the CPUs are based on.

However, this means that both the processors have same performance?

I think I should tell all the secrets here and end this article. Do you think that I will do this?

Absolutely no, this secret would be revealed at the end. So, keep quiet and read this article fully.

Before going further, I would like to tell you about all the models of i5 10th gen processors and i7 8th gen processors.

If you look at each of the processors name you’ll see some characterstics in it.

All of the processors have a alphanumerical names in which there is unique numbering pattern at the start and alphabets at the end.

Pro tip

There is a pattern in naming of CPUs of intel. The 8th gen CPU names are started with 8 and 10th gen CPU names are started with 10.

The next three digits in the name is known as SKU (stock keeping unit) which is more popularly known as model no.

The name ends with or without an alphabet. Every alphabet at the end has a significance. Here is an example of what each part of processor name signifies.

Intel core i5 10th gen vs i7 8th gen.
  • B – No description.
  • F – indicates that there is no integrated graphics.
  • G – It tells it has an integrated graphics available.

The number after the processors which have integrated graphics tells the graphical quality of the integrated graphics.

“7” – Most graphical processor. “1” – Least graphical processor.

  • H – High performance graphics available.
  • K – Unlocked version.
  • S – Special version of CPU.
  • T – Power optimised.
  • U – Ultra low power.
  • Y – Extremely low power.

Specific technologies related to CPUs.


When a CPU writes a data, it takes ram into consideration for information. That can take some time.

To speed up this process, the CPU stores the frequently used data in a specific memory that is known as cache memory.

Cache memory is present at various levels such as L1, L2 and so on.

The smart cache is present at level 2 or 3.

It is available for multiple execution cores and has the advantage of faster transfer of memory among different execution cores.

Cores and Threads.

If I will tell you in simple language, cores increase the amount of work that a processor does in a particular time.

On the other hand, threads increase the computational speed of your processor.

There are both single as well as multi core CPU present. In the i5 10th gen CPU as well as i7 8th gen CPU there is maximum 6 cores present.

Just like threads, threads can be single threading or multi threading (hyperthreading).

If the number of threads is equal to core count then it is single threading CPU.

However, nowadays most of the CPU has multi threading which has 2 threads per core as it helps a lot in editing and multitasking.

In computer language, the core is a hardware component of the processor and threads are virtual ones for managing multi tasks.

Clock Speed.

The clock speed of the processors are given in GHz. Every CPU has a base clock which tells how fast it processes the data at the normal conditions.

Generally, a higher frequency means denotes a better performance in heavy video output tasks such as gaming.

However, one should not determine the best CPU for him/her on the basis of frequency of the processor.

It is because various factors which accumulates and decides whether a CPU is good enough or not.

Also, nowadays CPU has a Turbo boost technology that enables the user to over clock its CPU.

Over clocking means to increase your clock speed from the original boost clock limits told by the manufacturers.

Both 8th gen and 10th gen CPU comes with overclocking.

So, with this basic information let’s talk about the pros and cons of 8th gen CPUs and 10th gen CPUs.

Pros and Cons of 8th gen CPU’s.

  • Power of 10: Intel claims that they have increased every feature of their processors 10 times than its predecessor. The improved features include 5.3GHz of frequency, 4k HDR, good GPU architecture etc.
  • Faster: With the faster rate of frequency in 10th gen processors you can do encoding and AI (Artificial Intelligence) work easily.
  • Applications: It can smoothly run many high end application such as applications made for AI work. Due to its sunny cores its IPC or instructions per clock is 18% higher than the types of cores in previous gen CPUs.
  • Advanced features: This intel chipset comes with many advanced features such as WIFI 6 and thunderbolt 3. The thunderbolt 3 helps in saving the internal space and improve functionality of the desktop/laptop. Whereas, WIFI 6 helps in transferring the files with a humongous frequency of 2.4GHz.
  • Integrated graphics: The integrated graphics in this 10th gen processor has took a great leap than its previous generations. According to Intel, this iGPU can reach 1 Teraflop performance which support 1080p gaming as well.


  • Not for all users: Intel 10th gen CPUs have a monstrous CPU frequency but it is not suitable for all users. Surely, AI is surely a great feature in these CPUs but for other encoding work various applications not only depends on frequency but on other factors as well.
  • External GPU: If you are a casual gamer and can play mordern games on 720p or 800p then igpu is enough for you but if you want good fps gaming then external GPU is must.
  • Hardware: If you are planning to upgrade your old pc and wants to install intel 10th gen CPU then it can cost you more than the price of the processor. It is because if you want to take the full advantage of these CPUs you will be needed different hardware and it will put a heavy weight on your pocket.

Processor Power Benchmarks (Cinebench R20 test).

i7 8th generation CPU benchmarks.

For this benchmark test, I have taken Intel core i7 8700K CPUs.

Here is a graph from techspot which tells the cinebench R20 multicore results of different processors.

In this graph, we can see that i7 8700K has 3604 multicore score in cinebench R20 score which is quite good.

However, we can also see that the Ryzen 7 2700x which is its competitor has better multicore score than this processor.

Now, here is the single core score of i7 8700K processor in cinebench R20.

Cinebench R20 benchmark of i7 8700k

Its single core score is 481 which is super awesome.

It has changed the game because in multi core this processor was defeated by Ryzen 7 2700X but in single core it is beating it with a large margin of 52 points.

i5 10th generation CPU benchmarks.

For this benchmark, I have took i5 10th gen 10600k processor.

Here is a graph from the which tells the cinebench R20 multicore score of i5 10600K.

Cinebench R20 Intel i5 10600k benchmarks

The multi core score of i5 10600k is 3591 which is good enough.

However, same as in i7 8700k the ryzen 5 competitor CPU has more multicore score as you can see in this graph.

Cinebench R20 Intel i5 10600k benchmarks

The single core score of i5 10600k is 503 which is great.

However, the interesting fact is that Ryzen 5 3000 series has finally overtook i5 10th gen intel CPU in single core score as well.

Conclusion of the War.

Yes, I know the core scores have told the story that who is the winner.

However, I must tell you that in this article I have included the benchmarks of only one 10th gen i5 and i7 CPU.

So, if you will see the benchmarks of other i5 10th gen and i7 8th gen CPU you can see that they have somewhat same performance in daily tasks.

However, I don’t deny that i5 10th gen has some advantages over i7 8th gen which makes it better in some manners.

1. All the 10th gen i5 and 8th gen i7 CPU comes with 4 or 6 cores with hyper threading (2 threads for one core).

2. Many i5 10th gen CPU comes with 12mb of smart cache. However, some CPUs also have 8mb and 6mb cache as well.

3. On the other side, i7 8th gen CPU comes with 12mb cache memory but majority of them has only 8mb cache memory.

4. If we compare the frequencies of i5 10th gen CPUs and i7 8th gen CPUs then it is clear that i7 has won this battle. And that is the reason why gamers prefer i7 8th gen over i5 10th gen.

Some newer edge giving technologies of 10th CPUs.

1. Excellent graphics.

The 10th gen CPUs comes with intel UHD or iris graphics which has took a huge leap from the previous gen integrated graphics and took it to the next level.

Intel 10th gen Integrated GPU name

It supports 1080p gaming due to the performance of the iGPUs. All these features give the gamers memorable gaming experience even on their iGPU.

2. The Adaptix technology.

With the adaptix technology which helps in overclocking of the CPUs which increases the overall performance of CPUs as well.

3. Thunderbolt 3.

Thunderbolt 3 as I have previously mentioned that it helps in saving the internal storage of your system.

However, it has other benefits because this single port can do the work of almost all the other ports of your laptop.

Thunder bolt 3 advantages for PC

It can perform tasks like powering the PC, transferring data and also helps in connecting the system with two 4k UHD displays as well.

4. Intel Optane technology.

Intel optane technology helps in removing the bottlenecks by allowing for higher storage.

As we know that more the storage more will be the processing speed.

This technology helps in the utilisation of the full power rather than using only a small part of it as in the previous gen CPUs.


On the performance point these i5 and i7 CPUs are almost equal to each other in all the fronts.

Here are some factors which you need to consider before buying any one of the CPUs.

  • The 10th gen CPUs has a better smart cache memory in it.
  • The cores and threads are similar but i7 8th gen frequency range ins more than i5 10th gen.
  • On overclocking side i7 8th gen is better.
  • Also, the price till date which I am writing this blog post i7 8700k processor price in India is 30,000 almost and i5 10600k price is 25,000 INR.

However, if you are taking this CPU for only gaming purpose then if you will pair these CPUs with good graphics card then its overall performance would increase.

So, that’s it for this article hope you find it helpful and knowledgeable.
