Topic: what does a processor do for Gaming? Everything you need to know before buying a PC
A central processing unit (CPU), also known as a processor, is the part of a computer that carries out computer programs. It does this by retrieving instructions from memory. The CPU is the brain of the computer.
If you are having trouble with your games running slow, one problem could be your CPU.
If you are thinking of buying a new PC or upgrading your old one, then your CPU is even more important. And yet most people would not have the slightest idea how fast it should be.
In this article, I will explain what a processor does for gaming and why you need to know about it before you buy a computer.
What is a CPU?
A CPU, or Central Processing Unit, is part of a computer hardware system. It contains the circuitry that accesses and manipulates computer memory on instructions from software applications.
CPUs are also referred to as the “brain” or “mind” of a computer system, because unlike memory which can be read at any time without harm, writing to the memory can corrupt or destroy data.
Cores and CPUs
In computing, a core is a processor as it exists in an integrated circuit, containing both the control circuitry and a portion of the arithmetic logic unit.
The term can refer to a microprocessor, which is an individual component including a CPU and L1 cache memory on a single chip.
It’s common for different manufacturers to have their own definition of what constitutes a core.
For example, both Intel and AMD call their cores “cores”, however on AMD’s side, two of their four CPU modules are called cores, even though Intel would only count them as one.
Being able to easily describe how many processors there are in something can be very difficult because of this. For some devices such as phones, tablets, and many forms of embedded hardware, the number of cores will be given.
For desktop computers and servers, however, it is very hard to find out how many cores there actually are without manually counting them or performing advanced testing on the device.
In modern CPUs, each core can individually process an instruction in a slightly delayed manner. This allows the CPU to schedule multiple instructions at once and switch between them in order to multitask.
Many operating systems use this scheduling feature to allow multiple applications to execute at the same time.
CPUs and Gaming
A core is a single physical component that can execute instructions.
Processor manufacturers do release CPUs with more than one of these cores per chip, or sometimes they make it easy for us to create our own virtual cores within the hardware.
This is done for multiple reasons, but mainly because it allows people to get things done quicker.
However, when it comes to gaming, one core is what you want. Granted two cores, or even four are better than one, but three or more cores can actually be worse for your games.
The reason for this is simple. In order to draw a 3D scene on the screen, the CPU must issue drawing instructions, calculations about how these things are being drawn, and data about where they are being displayed on the screen.
The more cores you have, the more of these tasks can be done at once without taking up space within your CPU.
In fact, three or more cores can work against you when it comes to CPU-intensive tasks because they require far too many instructions from the CPU. This leads to a slower frame rate and screen redraws in video games.
Which CPU should I buy for Gaming? Intel or AMD?
Intel is usually more expensive than AMD, but the performance per dollar on their “i” series CPUs is often better than anything else on the market.
Since gaming requires little memory bandwidth and no GPU processing power, buying an i5 or i7 is enough to get you started with near-future proofing for games at least two years in the future.
AMD’s CPUs are cheaper, but their performance per dollar isn’t much better than Intel’s when it comes to gaming.
You can get an AMD CPU that performs nearly the same as an i5 for half the price, which is great, but Intel will usually still perform better and give you a smoother experience in your games.
However, if you are on a tight budget, AMD has a slight edge.
How many cores are there in my CPU?
This depends entirely on your manufacturer, but if you want to find out, performing a google search for “manufacturer brand model core count” should produce good results.
If that fails, however, it may be worth looking into your device’s manual or other means of finding you can always manually count them yourself.
How do cores affect my game’s performance?
The more cores you have, the better your CPU will perform when it comes to highly multithreaded tasks such as rendering graphics in a video game or streaming gameplay.
However, if you are only running one task at once, having too many cores for a single task can slow your performance down because each core must work on a separate instruction in order to avoid conflicts.
Is CPU or GPU more important for FPS?
Overall, the CPU is what you should focus more of your attention on when optimizing a game. Typically modern CPUs will be able to perform just as well as GPUs when it comes to FPS in most games.
However, the more effects and environmental objects in a scene that you add, the easier it is for games to bottleneck on your GPU.
Do faster Processors use more Power?
Yes, but they also tend to use more voltage which can actually be worse for your electricity bill.
Generally speaking, you will want the highest GHz per core that you can afford within your price range if you are looking for a processor made specifically for gaming.
Do higher Cores equal higher FPS in PC Games?
-No, more cores do not mean better performance when it comes to PC games.
-Most PC games are only optimized for one thread, meaning they only process on a single CPU core at a time
CPU plays a vital role in the performance of computer games. It’s hard to find out how many cores a CPU has unless you are experienced in testing, but it is important to note that more cores may not always be better.
Intel CPUs have higher prices but are also faster, while AMD processors are cheaper but offer comparable speeds for gaming.
