How to Choose a GPU for Your Processor [Complete Guide]

With the launch of so many new graphics cards in recent times it has become really confusing for the customer to keep up with the advancing technology unless they are well versed in the technical lingo. Gaming was not a big thing until the late 2000s and now it has reached mainstream popularity thanks to the rise of so many new streaming channels and powerful PC hardware components.

Before this, all that mattered on a computer is the processing power of the CPU until Nvidia introduced their lineup of gaming graphics cards. In this current era, the need for a GPU is quite essential if someone wants to take their gaming to the next level.

AMD with the new Ryzen Zen 2 processors is a major competitor in this market. There range of Ryzen processors are not only cheaper than those of intel but also provide quality experience for gaming. For example combining the Ryzen 5 3600 with a great GPU is often what people do when building a Budget gaming PC.

In this article, we will not only cover the reasons why you should buy a good graphics card for your gaming rig but also the factors that you need to look into while buying one.

Why Do You Need A Good GPU?

With the drastic advancements in technology, we have so much to work with and we are not only talking about games since companies keep on launching new software and programs to make work easier for the consumers. The need for a graphics card is vital not only for gamers but also for engineers, designers, scientists, and filmmakers with high-budget projects under their belt. Generally, a graphics card is always required in case you plan to work with images and video processing. Even the display of your desktop requires a minimum amount of graphics memory in order to work.

To make things affordable for the people, tech companies and manufacturers like Intel and AMD often offer built-in graphics with their budget processors. They provide the minimum graphics memory that you need to run your computer, your display and get by with some gaming and basic level video and image editing but there is only a little that a built-in integrated graphics card can handle and that is why you will always require a higher-end graphics card to pair up with your CPU to get the most out of your entire system.

Moreover, the high-end processors on the market such as Intel’s Xeon series, 9th Generation Core processors and above, AMD’s Threadripper series processors, and a few of Ryzen ones do not come with integrated graphics as they are specifically designed to provide you with pure processing power and in such cases getting a GPU is a must as you would not be even able to turn on your computer without one.

The thing is, what type of graphics card you need is always dependent upon the type of work that you wish to perform on your computer. In many cases, you might even require more than one GPU and you can obviously do that, thanks to AMD’s CrossFire technology and Nvidia’s SLI system. Such systems are meant to handle graphics-intensive tasks such as 4K video editing and gaming on multi-monitor setups or so.

As far as gaming goes, you will always find two types of games- one that is GPU intensive or another that is CPU intensive but in the end both require a GPU to run so it is recommended to pair a good CPU with a similarly powerful GPU to prevent bottlenecking and limiting the capabilities of your PC.

Factors To Look At When Buying A GPU:

In this part, we will help you to choose a graphics card and list the specs and factors that you should check out before getting one.

Memory Size:

Obviously, the first thing that you will find next to the name of a graphics card is its memory size since it is quite essential for video processing and gaming in general. If you plan to get a gaming rig for 1080p gaming on high or even ultra settings then a 4 GB graphics card or higher will suffice. Such a card should be enough to get you playable frame rates of 60 FPS or more for most games. For 4K gaming or video editing going with an 8 GB GPU is the safest option.

Form Factor:

The size of your GPU might not be the most important thing but it is definitely important if you already have a pre-bought PC cabinet. Most ATX cases are large enough to fit in 2000 series Nvidia and 5000 series AMD GPUs. A dual-tower case would fit in absolutely any graphics cards and for ITX builds you can check out the low profile variants of some graphics cards such as the RTX 2070 Super Mini or the GTX 1650 Super.

Power Connector:

A standard PCIe x16 slot is only capable of delivering 75 W of power which is very low for high-end graphics cards that come with a 6-pin or 8-pin power connector. Unless you plan to go with a budget graphics card, make sure that you have got a decent power supply with a 6 or 8-pin power connector to plug into your GPU.

Clock speed:

The clock speed is not significant between two different price GPUs but among the ones that are, even a slightly more clock speed can offer you a serious FPS boost in modern Tripe-A titles. Other than the clock speed, the number of cores and the architecture of the GPU must be factored in too.

Integrated V/s Dedicated GPU:

As we have previously discussed, some CPU manufacturers like Intel and AMD especially combine a graphics processor with a CPU itself. Intel is preparing to enter the GPU market current but up till now the integrated graphics (Intel HD and Iris graphics) on their chips only provide the basic minimum required to run your display and light graphic related tasks.

AMD on the other hand launched their APU (Accelerated Processing Unit) series back in 2011 which combined a much powerful graphics processor on the CPU chip itself. The APUs are still a thing and are now sold under the Ryzen name as the Embedded G series processors. An integrated GPU is fine if you are under a budget and as long as you are happy with lower resolution gaming and low graphics-intensive tasks.

On the other hand, a dedicated graphics processor is a completely discrete hardware component that is separate from your CPU. Such GPUs are also called a graphics card and they connect to the motherboard via the PCIe x16 slot. While an integrated GPU makes use of the RAM in your system, a dedicated one has its own memory known as VRAM. These graphics cards are specifically engineered to provide unmatched graphics processing power for professionals and gamers who want the most out of their system. For graphics designers and gamers especially this type of GPU is the ideal choice and enables you to get by with faster, efficient rendering and 1080p gaming or even higher resolution gaming with max settings.


In the end, the type of GPU, the number of cores, or the clock speed that you need, all boils down to one thing and that is, it depends on the type of work you do or what resolution gaming you wish to play. For large graphic intensive projects such as graphics designing, 4K video editing, or image processing one should always opt for a high end dedicated GPU such as the RTX 3080 or at least the GTX 1660 as they give you pure performance that you solely require to get such tasks done. For gamers out there, an RX 5600XT should be sufficient for 1080p but if you want something for 4K then go for the 5700XT or an RTX 2070 or higher card.
