Choosing the right processor is a difficult task. If you've read this guide, you most likely need help and found the right place.

Whether you decide to upgrade your desktop PC or want to build a new PC, choosing the right CPU for your needs becomes increasingly difficult.

As Intel and AMD rush to introduce faster and more powerful processors than ever, it can be difficult to choose the processor that is best for you from a wide range of options.

Generally speaking, you must make a choice based on performance and performance. Cost-effectiveness. However, there are many other factors at play, which is why we made this comparison to help you make a decision.

In this article, we will compare the two processors and explore whether there is a reason to buy the updated i79700K instead of the older but still powerful i78700K.

Before starting the feature comparison, we first arrange the 9700K and 8700K specifications so that you can see the differences (or missing!) for yourself.

For convenience, we have divided them into several tables, covering general, performance, memory, and of course power specifications.

The following are the most common features to consider when considering which Intel Core i7 processor is right for you:

The first feature we will consider is the number of cores per CPU. The core is essentially a single processor inside the CPU.

Today, most computers manufactured today have multiple cores, which means that the CPU has multiple cores.

core vs. line; the core is the hardware component, and the thread is the virtual component that manages the CPU tasks.

In contrast, threads are "virtual" versions of CPU cores, and the presence (and their number) of threads helps improve performance.

Therefore, if there are multiple threads, the CPU will be able to process multiple tasks at the same time without problems. There are active threads alongside the cores of the 8700K and 9700K, which we will describe below:

Since the Intel Core i7 9700K is an updated model of the Intel Core i7 8700, Intel provides you with two additional cores. 8 threads, bringing the total number of cores to 8.

On the other hand, although the Intel Core i7 8700 has only 6 cores, it has more threads than the updated i7 9700K. The i7 8700 has 12 threads, 12MB cache, and 95W TDP, so its workload capacity is comparable to that of the Intel Core i7 9700K.

Although multi-processor cores are one of the most important indicators of performance efficiency, it is equally important to consider multi-threading.

If you choose a CPU with more threads, your computer will handle multitasking better, because threads will help organize the workload on the CPU in a more efficient way. Another measure of

processor efficiency is clock speed or clock frequency. For simplicity, this is the speed at which the processor executes instructions.

In order to follow instructions correctly and on time, the CPU will require a fixed clock cycle. Think of it this way: the faster the clock speed, the more instructions the CPU can process per second.

Generally, the clock frequency is displayed in GHz or MHz. The clock speed of the Intel Core i7 9700K is 3.36 GHz and one of the processing cores is up to 4.9 GHz.

In contrast, the The base frequency of the Intel Core i7 8700 is 3.7 GHz, but if it is overclocked, it can reach up to 4.7 GHz.

However, among the two, Intel Core i7 9700K ranks first. Because it has a non-disruptive heatsink, if you want to overclock for speed, the 9700K will be able to keep the CPU cool and running normally. In contrast, the 8700K can overheat and have a difficult time maintaining performance efficiency.

Thermal management is closely related to the above point of view. Having efficient CPU thermal management is essential for extending processor life and achieving faster overall computer performance.

Generally, the most common way to regulate heat is to install fans, which can blow hot air out of the CPU and out of the chassis. Also, cooler air can sometimes be blown into the CPU to keep it at a lower temperature.

For the Intel Core i7 9700K, due to its faster clock speed, this means that it requires a more efficient cooling system than a weaker CPU.

As we mentioned above, it is equipped with a soldered onboard heatsink to keep the CPU cool while it is running. The 8700K does not have this feature, and many people report that you will experience hot spikes during overclocking. In addition to

, both CPUs use so-called gold-plated solder, which replaces the older traditional thermal paste that Intel has known to use in the past. updated

Even record with your camera while you are doing it.

In addition, if you use a desktop computer, it will also come in handy, although if you use a PC workstation, it may lag behind.

As for overclocking? Surprisingly, compared to a single-core chip, the Intel Core i7 9700K is only 1% higher than the 8700K, which is very interesting considering that the 8700K has four more threads than the updated 9700K. In addition to overclocking, the 9700K also occupies a dominant position in quad-core, 8-core and dual-core benchmark tests.

When comparing speed and efficiency, 9700K has a 5% advantage, and scores more than 90% in games, desktop use, and PC workstation use.

On the other hand, the 8700K scores slightly lower in terms of speed and efficiency, but still scores more than 90% in games and desktop usage, and 84% in PC workstation usage.

Based on these benchmarks, it is safe to say that there are not many obvious differences between 9700K and 8700K. However, the 9700K has a faster response time, can handle multitasking, and has an extremely fast clock speed that can support games and general purposes, whether you are using a desktop computer or a PC workstation. The

Intel Core i78700K was launched in 2017 at a price of US$359, which was a rival to AMD’s best Ryzen processors at the time (including the best-selling AMD Ryzen 7 2700X (US$329)).

In contrast, the Intel Core i79700K was launched in 2018 at a price of US$374, and Intel gave it a slightly higher price difference than the 8700K. When

was actually launched, many retailers estimated that 9700K would enter the market at a price of more than $500.

Currently, the price of Intel i79700K is higher than Inteli7 800K, you can check both here:

Please keep in mind that purchasing any of these processors may require the purchase of additional items, such as motherboards, cooling systems and supporting CPUs.

Before purchasing, we recommend that you first determine what additional factors you may need, and then quickly estimate the total cost.

So which one is better?

Comparing the two, it is difficult to say the winner! Although the Intel Core i7 9700K can be said to have the upper hand, both processors provide fast and efficient performance.

This is an excellent gaming chip suitable for desktop and PC workstations. However, to help you decide which CPU is best for you, check out our roundup of both below.

If you are a gamer and looking for a chip that can provide you fast and smooth gaming experience and fast and efficient overall usage, then this is the CPU for you. The

Intel Core i7 9700k will ensure that you have no lag during the game and can easily operate multiple programs and applications.

9700k has durable single-threaded capability, all thanks to its high turbo clock speed. Not only that, it is also a soldered CPU, which will help improve overall heat transfer. This means that whether you are playing games or running new software on your computer, you will always have a great CPU with excellent performance.

If you are looking for a CPU that is mainly used for gaming, then the Intel Core i7 8700K is your best option. The

Core i7 8700K has 6 cores, 12 threads and a turbo frequency of 4.7 GHz. It is a powerful gaming chip. Although it is older than other processors on the market (including 9700K), it is still highly regarded by the gaming community as one of the best CPUs for running games, and due to its multi-core, it can handle about 60 fps.
