Intel Core i7

Intel core i7 8700k and Intel core i7 9700k are both amazing high-end CPU processors. Though Intel has already launched the 10th and 11th generation of the processor, no one can deny that the 8th and 9th generation is still improving and are perfect for this era as well. These computers can be a bit weaker than the 11th generation processor, but they still offer top-notch performance with no hiccups or delay.

If you are confused between these two amazing processors offered by Intel, we are here to discuss them with you so that you can decide wisely. In this article, we will discuss which one can be the perfect choice for your next build-up.

Let’s start.

Core i7 – 8700K vs. Core i7 – 9700K

Though the Core i9 and Xeon series offered by Intel is undoubtedly the most extreme CPUs offered by Intel, it doesn’t deny the fact that Intel core i7 still has it’s market because of some obvious reasons. It is a high-end computer CPU offered by Intel. Besides providing the users with amazing performance, this also comes at an affordable price, which is obviously a reason for it’s success. If you are planning a new setup for gaming or productivity, it can be a good option for you.

So, what are the differences between Core i7 8700K and Core i7 9700K, and which one should you go for?

This article will discuss every prospect of these two processors in detail. Before that, it should be mentioned that besides some differences, these two processors have several similarities. Both of them come with Intel core i7 titles.

Before moving further with the article, let’s know about both these processors in brief.

Core i7 – 8700K

Previously, Intel had no competitor in the market, and that’s why they were quite relaxed about their grip on the market. However, when AMD introduced the Ryzen processor, it literally surprised Intel authority. As a result, they started to work on their processors even more. AMD took an amazing marketing strategy: providing more cores at a comparatively lower price. As a counterattack, Intel increased the core count in the 8th generation processor. The Core i7 was introduced with 6 cores and 12 threads.

8700K is clocked slightly higher than the previous Intel Core i7 7700k and has 2 lesser cores. Though the base of the core 8700k was 3.7 GHz, which is lower than the older core i7 7th generation processor and the 6th generation processor, it had an amazing boost clock value of 4.7 GHz. We also have to mention the clock multiplier value, which is 37.

Besides that, it comes with 95W TDP, and also it is ideally cooled with its quality stock cooler. One can use an AIO cooler or opt for water cooling in the case of overclocking. Previously, this processor’s price was around $385, but nowadays, it is around $400. You can find one if you are desperately looking for it as it has become difficult to find in the recent market.

Core i7 – 9700K

It is not too much different from the i7 8700k as both processors have the same coffee lake architecture. Also, both processors have 14nm process nodes, but when it comes to performance, there are some slight differences between them.

Though in Intel Core i7 processors, Intel gave attention to hyper-threading, in 9700k, it used something which is the same with The 8700k. This processor also comes with 8 physical and 8 logical cores.

Though the base clock of 9700k is not that impressive as it has only a 3.6 GHz base clock, it ramps up to 4.9 GHz. On the other hand, the clock multiplier rate is 36, which is quite impressive and can efficiently push over 5.1 GHz in the case of overclocking. Now, if we mention other features of 9700k, we can mention it’s impressive TDP of 95 watts. The processor uses the stock cooler in vanilla settings which helps the processor to keep cool when used. If you are overclocking the processor, you can always use an AIO water cooler.

Talking about the price, the processor was launched with a price rate of $359, but unlike 8700k, the price dropped, and in the recent market, one can get it at any price within the range of $260 to $300. According to the market experts, the reason for this price drop is nothing but Ryzen 3000.


The Core i7 8700K and the Core i7 9700K share several things in common. We have mentioned previously that both processors use Coffee Lake architecture and come with similar specifications. Before comparing these two processors, let’s briefly discuss their similarities:

  • Both have the same Core architecture Design (Coffee Lake)
  • Both are supported on the 300 series chipset motherboard chipset and LGA 1151 socket
  • Both of them use the 14nm process node
  • Both have unlocked Processor (Core i7 – X700K, “K” suffix)
  • Both come with Intel UHD 630 graphics
  • Both have Max 128GB DDR4 2666MHz RAM support
  • Both of them come with PCIe Gen 3.0 with 16 PCIe lanes
  • Both have 12MB L3 Cache

In the multicore performance, they have some differences as core i7 9700k comes with two additional cores. But if we discuss single core performance, both processors share several similarities.

Both Core i7 8700 and Core i7 9700K are compatible with the same 300 series Intel motherboards, and both are based on the same Coffee Lake design. One can upgrade from 8 generation to the 9th generation easily because of motherboard compatibility, but after the 9th generation CPUs offered by Intel, the CPUs are not compatible with 300 series motherboards, and that’s why no one can update that to the 10th generation or upcoming 11th generation Intel processors.

If we discuss the differences between the i7 9700 K and i7 8700k, we can say that both are the same, but the Intel core i7 9700k just has two extra cores and a removed hyper-threading. The 9700k is nothing but the revised version of the 8700K, which was created in a hurry as because of the increased demand for Ryzen CPUs in the market, Intel has to increase the core count and push the 14nm process node to it’s limit to continue being the leading company on the market.


If you have enough knowledge about the processors, you may know that Intel provides many versions of every core series. The i7 also comes with more than 3 versions, such as Core i7 9700K, Core i7 9700KF, and Core i7 9700F. Though they are the versions of the same series, they are differentiated with the suffix at the back.

  • The K suffix refers that the processor is unlocked and is overclockable.
  • F reflects that the processor has no integrated GPU. In this case, the user cannot boot without an external GPU.
  • KF reflects that the processor is unlocked but doesn’t feature integrated GPU

Performance Review

Though they are older CPU versions, it will be fair if we compare them with 9th generation and 10th generation Intel core processors as these processors have already launched into the market. The Core i5 9600K and Core i5 10600K can reflect how much the core lineup has recently improved.

Cinebench R20: Higher Point is better

  • 9700K- 500-single core, 3726-multi core
  • 8700K- 466-single core, 3380- multicore

In this comparison, we can say that 9700k is better.

7-ZIP: A higher point is better

  • 9700k – 52587- compress test, 64003- decompress test
  • 8700k – 51330 – compress test, 59164 – decompress test

In this comparison, 9700K wins

Hand Brake: Lower Time is better (Measured in minutes)

  • 9700k- 16.6
  • 8700k- 18.2

9700K offers more impressive results in this comparison as well.

Blender Open Data Render: Lower Time is better (Measured in minutes)

  • 9700k- 21.3
  • 8700k – 20.6

In this comparison, 8700K is the winner.

We can say that Intel core i7 8700k loses in the comparison of single-threaded workload and core i7 9700k wins the battle. In the Cinebench test, we saw that the performance of the Core i7 9700K is increased by 7%. It is not only with the single-threaded workload, but if we talk about multi-threaded work, Intel core i7 9700k outperforms i7 8700k, but in that case, the competition was neck to neck.

If we give enough attention to the comparison, we can clearly see the influence of an increased TDP and clock speed. So, we can conclude saying that the i7 9700K offers a more powerful processor with a performance rate that is increased by 5% to 7%. This is not a great consideration if we look at the extra 2 cores and bumped up the clock speed of the 9th generation.

Gaming Benchmarks:

As we have already tested the performances of both the processors, it’s time to check which processor can give a better experience to gamers. Here, all the gaming tests are done with 1080p with high settings. This is the perfect resolution to display the power the processor has. We could have tested it under 1440p resolution, but the graphics card would not be able to influence the gaming performance to the fullest. For the best result, we have chosen 1080p. The results were shocking as the CPUs scored similarly with little to no differences. If you think the generational jump will increase your gaming experience, we need to tell you that it will not do anything like that. Only in CSGO, there is 1% difference in the performance as this pushes frames more than intended. It is also clear that being an 8 cores processor, the i7 9700k doesn’t have any noticeable differences from i7 8700K with 6 cores. The gaming usually depends on the single-core performance of the CPU and in this case, there is very small to no difference between these two processors.

Power Consumption

If we compare these two processors, we should not avoid the matter of power consumption as, in the long run, it is also a matter of concern. The comparison shows that Core i7 9700k consumes something around 192 Watts, and Core i7 8700K consumes something around 177 Watts. So, in this case, there are not too many differences between these two processors.


While purchasing a processor, the price plays a big role as it is important to consider whether you are getting value for money or not. The processor’s pricing is something you should consider while choosing the perfect one for your upcoming set.

First, let’s talk about The Core i7 8700K. Previously it had a pricing of around $386 when it was first launched on the market. With time, the price of this processor has increased, and now it is retailed for around $400. As it is an old processor, we can say that it is a bit too expensive.

In this case, Core i7 9700K has some benefits. When it was launched for the very first time, it was retailed for around $349, but with time, the pricing went down, and now you have to invest something around $260 to $300 to get one. You should thank Ryzen 300 and Ryzen 5000, who became a threat to the market of Intel, and the company needed to cut off the price.

So, if we discuss the value comparison, we can say that buying a new Intel core i7 9700k will be a better option.

As we are almost done with the comparison, let’s have a quick look at the pros and cons of each processor so that you can make your decision wisely.

Core i7 8700K


  • Hyper-Threading
