GPU or CPU: Which Is More Important?

Are you looking to get a gaming laptop, and do not know which is more important between the GPU or CPU? Yes, they are all important for the perfect workability of a gaming laptop, but there has to be one that is more important right? Well, you’d have to find that out yourself in this guide.

We would be considering the topic ‘GPU or CPU, which is more important for a gaming laptop?’. Read through this guide, and your question will be answered.

What is the CPU?

The central processing unit (CPU), also referred to as the “processor,” carries out and controls the computer program’s instructions by performing input/output (I/O) operations, basic arithmetic, and logic. An essential part of any computer, the CPU receives, directs, and processes the computer’s data.

Since it’s usually the most critical component, it’s often characterized as the “brain” or “heart” of the laptop PC, depending on which body part you’d consider the most important. And when it comes to gaming, it’s a pretty important component of the gaming system.

A CPU “core” is also another word for the CPU’s processor – they’re all synonyms. Historically, processors had only one core that would focus on one single task. Today’s CPUs, however, have between 2 and 28 cores, each of which focuses on a unique task. So a multi-core processor is a single chip that contains two or more CPU cores.

And CPUs with more cores are more efficient than those with fewer. Dual-core (or 2-core) processors are common, but processors with 4 cores, also called quad-core processors (for instance, 8th Generation Intel® Core™ processors) are becoming more popular.

  • How does a CPU work?

The processing of commands can be divided into three main stages, i.e. fetching, decoding, and execution. The component fetches commands from the device’s RAM, decodes/translates the particular command, and lastly the command is executed by the relevant components of the CPU.

These commands include; basic arithmetic, comparison of numbers, calculations, etc. IN a computer, a number hence the simple commands above are the basic equate to the basic functions of the CPU (Centra Processing Unit) represents every information.

  • What specifications does the CPU for gaming have?

Original CPU models had only a single processing core, however technological advancements have seen this change to multiple cores that have significantly enhanced performance. You will find that majority of the CPU’s being sold now have a minimum of a dual-core.

There are also others with a quad-core, six, eight, and even some as high as 12 core. There are those with a multi-threading aspect that is meant to create a virtual processor core.

Another aspect of the CPU is clock speed. This is usually labeled as GHz, i.e. gigahertz. This component indicates the number of commands your CPU can handle in a second. The clock speed helps you to make a comparison of two devices that are from the same generation and have seemingly similar specifications.

Therefore, if two devices have the same aspects, you can make a choice based on the clock speed. However, it is important to note that a 3GHz processor from the year 2012 cannot be as fast as a 2GHz processor manufactured in 2019.

  • What is the Role of a CPU in gaming?

While many people may argue about the importance of a CPU in gaming, you need to understand that some games are better played with the CPU. CPU handles tasks better compared to the GPU. One of the tasks that require a good CPU is the aspect of the Artificial Intelligence Functionality of Non-player Characters. A good CPU will determine how characters in-game react to specific actions.

  • What type of games utilize CPU?

Certain games require a higher score compared to others since they actually need more CPU labor. Fact-moving games that involve first-person shooters, open sandbox games, multiplayer games, e.tc. Are developed in such a way that they perform better with multiple core CPUs as well as their multiple threads.

If you are playing a game requiring competitive players, using a higher refresh rate pc, e.g. 1080p, then an AMD Ryzen 1080X( which basically means 8 core with 16 threads) or Intel 17-8700k (i.e. 6 core with 12 threads) is best recommended to enhance and maximize your CPU gaming experience.

The Intel 17-8700k 8th generation boasts of being among the fastest processors with the highest clocking speeds (4.7 GHz).

For a game such as Grand Theft Auto, I would recommend that you use an Intel i5 3470, i.e. 4-core with 4 threads. The Intel i5, 2.8 GHz, 4-core with 4 threads, is the most suitable for Fortnite Battle Royale.

If you are a fan of Call of Duty: Black Ops 4, you are likely to get better performance with a CPU that has a quad-core processor at a minimum. For this game, the AMD Ryzen R5 1600 (6-core with 12 threads) or an Intel i5 2500k (4 core and 4 threads) are the most suitable for an excellent performance.

What is the GPU?

The graphics processing unit (GPU), also called a graphics card or video card is a specialized electronic circuit that accelerates the creation and rendering of images, video, and animations. It performs fast math calculations while freeing the CPU to perform other tasks.

There are two kinds of GPUs: One is an integrated (or embedded) GPU that lives directly on and shares memory with the CPU. And the other is a discrete GPU that has its own card and memory.

The GPU is an extremely important component of a gaming system, and in many cases, even more, crucial than the CPU when it comes to playing certain types of games.

Simple description: A GPU is a single-chip processor that’s used chiefly to manage and enhance video and graphics performance.

  • How does GPU work?

The graphics-processing unit is developed to perform complex geometrical and mathematical calculations that allow the rendering of graphics. Most fast GPU’s have multiple transistors compared to the CPU. Due to its high heat emission, the GPU is placed under a fan or sink heat.

More to the high processing power, special programming that enables it to analyze data and use it constitutes it.  Images created by the GPU are usually stored in its card’s RAM.

Data about the color, location on the screen, and pixel of the images is saved in the RAM.  The RAM also doubles up as a frame buffer, i.e. holds processed images until they are ready to be displayed.

Video RAMs are dual-ported and operate at extremely high speeds and therefore enabling the system to read and write simultaneously. It is directly connected to a digital-analog converter, otherwise known as DAC or RAMDAC, which translates images into an analog format that can be used by the monitor.

Cards with multiple RAMDACs can enhance performance as well as provide support for more than a single monitor.

  • What is the role of GPU in gaming?

Once you download your game, it is saved in the hard drive component, while when you upload a game, it goes into the RAM. For games like GTA, all its assets can’t be saved into the memory all at once due to their size.

Every aspect relayed on the screen is saved in the RAM. Therefore the RAM is merely storage. The CPU disseminates information to the GPU.

The process takes place in two steps; graphical components e.g. the textures and model are loaded into the VRAM. Since the GPU is incapable of accessing your device’s memory directly, it usually has its own memory to save the components it requires. Open world games require more VRAM due to their high number of components/assets.

The GPU is guided by the CPU on the various objects on your screen. It then converts this information to a complete image. You might assume that the CPU is superior to the GPU, but the latter handles more demanding tasks than the CPU.

The GPU renders your game’s weapon, your character, its effects, shading, texture, ripple effects, and other aspects of the game to your screen. Everything you see on the screen is rendered by the GPU.

  • What type of games uses GPU?

Due to the aspect of 2D and 3D graphics in most of the games developed, you might need to utilize your GPU more than your CPU. A powerful GPU is required to process 3D and 2D graphics, map textures as well as render polygons among other complex processes. You will get more frames per second depending on how fast your GPU is.

As a Call of Duty fan, you actually require a mid-range card such as the Radeon R9 390/AMD RX 580, GTX 1060 6GB, or the GTX 970 4GB. These GPU models are quite favorable for 1080 Pixels gaming.

For the more competitive player games, the GeForce GTX 1080nor Radeon RX Vega 64 is highly recommendable. These card models are considered high-range and are favorable for resolutions of 1440p Quad HD and or VR headsets as well as high-refresh-rate devices.

Are GPUs More Important Than CPUs

Ultimately, GPUs are most often brought up as part of gaming or video rendering. As AI and deep learning technologies expand alongside the rise in cryptocurrencies and Bitcoin mining, programmers are starting to use the GPU’s ability to multitask in more ways.

However, the average consumer looking to purchase a GPU as a separate component is probably doing so to get better performance out of a PC video game. This means a GPU has a greater impact on how a modern video game runs on a PC than a CPU will (unless the CPU is significantly underpowered).

However, most computing tasks unrelated to processing graphics are left to a machine’s CPU. That usually includes running an operating system, background programs like Discord, web browsers, downloads, and so on.

It could be argued, then, that the CPU is the most important part since it dictates more of a PC’s typical operations. Furthermore, every PC needs a CPU but not all have any use for a GPU.

A powerful graphics card will be more noticeable in a game, but a great CPU will be noticeable across the board. Still, advancements in graphical demands happen more quickly than computational demands, so a GPU will need to be updated more often than a CPU.

CONCLUSION

By now, you understand the basic concepts of both the CPU and GPU. It is important to note that both components can work together to complement each other. Major differences between the two arise in their functionality but they are quite similar. As a gamer, your personal requirements, device specs as well as interests in particular gaming modes will determine your choice for a processor.
