How Many Cores Do You Need For Gaming?

CPUs can make a big difference in gaming performance, but having a 10-core/20-threads processor is not always needed for a good experience. There are many good CPUs for gaming on the market, some with fewer cores (1-4), and some with more (6-+10). But, despite the many options, how many cores do you really need for gaming?

According to a Steam survey, four-core CPUs are the most popular for gaming (45.44%), followed by six-core CPUs (26.42%). Most modern game titles require 4-6 cores to run; however, high clock speed is also required. CPUs with 4-6 cores are the sweet spot for gaming.

Generally, the more cores a CPU has, the more tasks can be completed at a time. A jump from 2 cores to 4 cores can result in a higher FPS count in modern games. However, a jump from 6 to 8 cores usually results in a minor FPS gain. 

How much FPS you get with 4 or 8 cores also depends on the title itself. Not every game is optimized for a specific core count; for instance, Counter-Strike: Global Offensive runs excellent on two cores, Battlefield 5 already needs four cores to run best.

What Does A CPU Core Do?

A central processing unit (CPU) contains individual processing units (Cores), which receive instructions from a single computing task. After completing the tasks, the information will then be temporarily stored in the Random Access Memory (RAM).

Central processing units with multiple cores can complete multiple tasks at once. For instance, it enables the user to edit documents while watching a video or browsing the web.

For gaming, it is crucial to pick a CPU that can keep up with rapidly incoming information, such as audio and video. Hyper-Threading cores can improve the performance and speed up to 30% (click here to read more about hyper-threading from HP).

Is It Better To Have More Cores For Gaming?

Besides the CPU, the graphics card (GPU) is also an essential factor for gaming. Still, having a strong CPU can support the GPU, as demanding games require both a smart CPU and a powerful GPU.

CPUs can complete tasks GPUs are not performing well on, such as the artificial intelligence functionality of non-player characters (NPCs). Some games run better with more cores, such as The Witcher 3 or Battlefield 5, as they are optimized for a higher core count.

Other games may run better on fewer cores, such as Counter-Strike or League of Legends, because they are optimized to run on less cores.

 Depending on the game, a fast GPU is more important than a CPU with many cores. For instance, Minecraft, Counter-Strike, and LoL run on two cores just fine.

That said, if you want the best performance possible, going for a powerful processor, such as the Intel® Core™ i7-8700K, is needed. Choosing a powerful/high core count CPU also makes the system more future proof. 

With rising technologies like ray-tracing, it is expected that games will get more demanding over the next years. Enhancing your gaming PC with a good CPU makes sure you don’t have to upgrade in the next few years.

What’s The Minimum Core Count For Gaming?

There are quite a few games that run on only one core; however, if you want to play modern titles like Call of Duty, Battlefield, or Fortnite, you probably need to upgrade.

The minimum core count for gaming is two cores so that the processor can manage more than one task at a time. More demanding games generally require four cores on high settings, such as The Witcher 3, Battlefield, GTA 5, or Far Cry 5. 

If you’re looking for the right CPU for your PC, please note that clock speed is also an essential factor that you have to consider. CPUs with high clock speed can complete given tasks quicker, reducing the time you have to wait to interface with your applications and programs.

So, getting a powerful CPU with many cores is not necessary at all times, as you should choose a core count, depending on the games you want to play on the PC.

Here are the minimum CPU requirements of popular games, such as:

Game Title:CPU:Core Count:Threads:
Battlefield V:Intel® Core™ i5 6600K44
Call of Duty Warzone:Intel® Core™ i3-434024
Grand Theft Auto 5:Intel® Core™ i5 347044
Among Us:Intel® Pentium 4 2.00GHz11
Minecraft:Intel® Core™ i3-3210 3.2 GHz24
Fortnite:Intel® Core™ i5-7300U 3.5 GHz24
Overwatch:Intel® Core™ i324
Dota 2:Dual-core from Intel®22
Counter-Strike:Intel® Core™2 Duo Processor E6600 2.4 GHz22
Red Dead Redemption 2:Intel® Core™ i5-2500K44
Rocket League:Intel® Dual-Core™ 2.5 GHz22
Shadow of the Tomb Raider:Intel® Core™ i3-322024
Rainbow Six Siege:Intel® Core™ i3-560 3.3 GHz24
Assassin’s Creed Valhalla:Intel® Core™ i5-4460 3.2 GHz44

Do Any Games Use 8 Cores?

As modern games get more hardware demanding because of better graphics, more effects, and larger maps, older gaming systems start to struggle running such demanding games on high FPS. 

There are no game titles that require an eight core processor, such as the Intel® Core™ i7 10700K. However, games can still use eight cores, but they won’t run on max speed.

For instance, Battlefield V uses all six cores of my Ryzen 5 3600 processor, but they only run on 68%-80% performance. 

How Many Cores Do You Need For Gaming And Streaming?

Streaming is one of the most popular activities across the gaming industry, so there are countless streamers around the globe. Unfortunately, it seems that streaming while gaming requires a high-end gaming PC, right?

For streaming while gaming, it is recommended to have at least a six-core processor, like an AMD Ryzen 5 3600. Most games are optimized and designed to work on a four-core CPU, and it takes two cores for streaming. 

Processors with more cores and threads can provide a smoother gaming and streaming experience, making them more popular across professional streamers.

Here are some of the most popular CPUs for gaming and streaming:

CPU:Core Count:Threads:Base Clock:Max Boost Clock:
AMD Ryzen 5 3600X:6123.80 GHz4.4 GHz
Intel Core i7-9700K:883.60 GHz4.90 GHz
AMD Ryzen 9 3950X:16323.5 GHz4.70 GHz
Intel Core i9-9900K8163.60 GHz5.00 GHz
AMD Ryzen 7 3700X:8163.60 GHz4.40 GHz

Avoid System Bottlenecks

When choosing a CPU for your PC, the last thing you want is a bottleneck that prevents other components from using their full potential. For instance, if you pair a powerful CPU like the Intel i7-9700K with an Nvidia GTX 1650 Super, you won’t get better performance in-game.

Unfortunately, it is difficult to find out which CPU works best with a GPU, but you can use bottleneck calculators to find out how much performance you will sacrifice if you pair up a CPU with a GPU.

Please note that such calculators are not always accurate, and you should also take a look at some forums or ask some people who build PCs as their job.
