How Do You Choose a Good 3D/Graphics Card?

Gaming, picture and video editing, and other visual chores will suffer from an underpowered GPU, which will result in a poor visual experience. If you're not sure where to begin, our graphics card (or 3D cards as most like to call them) purchase guide will walk you through the process of selecting your new graphics card and taking control of your PC's graphics capabilities.

The graphics processing unit (GPU), together with the central processor unit (CPU), has the highest impact on your computer's performance. It is due to the GPU interpreting data from the CPU and displaying it on your screen. However, knowing all of the complexities that come with deciding whether to replace your GPU and choosing the correct graphics card might be perplexing.

What to Look for When Purchasing a Graphics Card

There are two primary companies to select from while buying graphics cards: AMD and NVIDIA. Both companies produce high-performance, high-quality graphics cards.

  • Firstly, you must select how much RAM you want in your graphics card.
  • Consider things like your PC's form type (desktop versus laptop), whether you want a separate GPU or a graphics card built into the CPU, and so on.
  • Consider the power connections that your card employs.
  • Take note of the graphics card's thermal design power (TDP). 

All of these factors will influence whether or not the graphics card will fit directly in your PC and get enough power and cooling.

Graphics - Integrated vs. Discrete

Integrated graphics are more frequent in smaller form factor systems like laptops, although they may also be found in desktop PCs for users who don't require high-powered visual applications.

Integrated graphics don't have their RAM, but they don't produce as much heat or consume as much power or battery life as discrete graphics. Integrated graphics are not recommended for graphically intensive games, although they are more cost-effective. They're also suitable for more basic visual tasks like watching movies and TV shows online.

If you want to use your PC for graphically intensive applications like high-resolution gaming, video editing, picture editing, and 3D rendering, you'll need a dedicated graphics card.

Unlike their integrated counterparts, these cards have their RAM. However, a discrete graphics card requires a suitable CPU to match and a cooling setup to keep your PC from overheating. It will also consume more power, necessitating a larger (and more expensive) power supply in your desktop PC to support two CPUs.

It also implies that if your laptop has a separate graphics card, you'll have a lower battery life than a laptop with a less capable graphics card.

Graphics Cards for Desktops vs. Laptops

There are different concerns for desktop and laptop graphics cards. Graphics cards are designed for varying devices, so there are differences in form factor, performance, and cost between desktop and laptop graphics cards.

Graphics card for Desktop PC: 

Form factor: 

One advantage of utilizing a PC tower is the opportunity to use heavier, more powerful components. The PC tower offers space and cooling. It is to handle the heat and power requirements of powerful GPUs.


You will enjoy higher specs compared to laptop graphics cards. It includes more memory bandwidth, a higher pixel rate, and increased texture mapping than laptop graphics cards.


Desktop PC cards are less expensive to manufacture because the hardware is less compact.

Graphic Cards for Laptop: 

Form Factor: 

Because your GPU needs to fit inside the tiny chassis of the laptop, smaller components are required. As a result, they are more energy-efficient and have advanced thermal and electrical technology. They are also made to be as silent as possible.


While manufacturers are moving closer to parity between desktop and laptop GPUs, as we have stated, laptop cards still underperform in several areas. 


Laptop graphics cards come at a high price due to the higher cost of producing components for a portable and power-efficient graphic. There are larger and more powerful laptop graphics cards available, but they add to the total weight of the device, make it hotter, and limit portability.


Ray-tracing is an intriguing new technology in current graphics cards. Ray-tracing is a rendering method that provides incredibly realistic lighting effects and is commonly used in gaming. It is accomplished via an algorithm that tracks a light path and then imitates how light interacts with real-world objects.

Ray-tracing is used extensively in games like Cyberpunk 2077, Watch Dogs Legion, and Control, which simulate how the human eye interprets light reflection and shadows. Ray-tracing is one of the most significant advancements in graphics in recent years, and it's something that both NVIDIA and AMD are working to improve with their newest GPUs.

Although ray-tracing technology has not yet achieved its full potential, game makers are adopting it. While film studios have been using the technology for years, notably in big-budget action blockbusters, rendering it in real-time in your PC game is more complicated. Previously, game developers employed a technique known as rasterization, which converts 3D polygonal models into a 2D picture and pre-renders light effects.

Even while ray-tracing is still in its infancy, modern graphics cards can nevertheless deliver stunning results. Everything from large explosions in a conflict to the sun's rays peeking through a window in a dimly lit area falls under this category.

How much graphics card memory is enough?

Your GPU executes a tremendous amount of computations per second when producing visuals. It occurs every time the image on your screen changes, even when you do something as basic as moving your mouse. Because the GPU is in charge of rendering these outputs, video RAM (vRAM) is required.

This memory is shared with the CPU when utilizing an integrated graphics card. Thus, only a portion of the total available memory is needed for graphic operations. However, a discrete graphics card has its memory, which it uses to generate details.

The more RAM a GPU has, the more detail it can process, although this has little bearing on its speed. A GPU with 2GB of RAM is more than enough for casual use, but gamers and creative professionals should strive for 4GB of GPU RAM.

The amount of RAM you need in a graphics card is determined by the resolution required to play games and the games themselves. Modern games, such as Cyberpunk 2077 and Control, require at least 6GB of RAM to operate at 1080p resolution and up to 8GB of RAM to run at 4K resolution with high texture quality and full ray-tracing capabilities.

What do the numbers on the model signify?

AMD and NVIDIA are the two leading GPU manufacturers on the market. In reality, NVIDIA popularized the term GPU in 1999, although it had been in use for at least a decade before. Both firms have made significant advancements in Graphics Processing Unit (GPU) technology.

AMD graphics cards

  • The RX branding is used on AMD's newest CPU series.
  • RX Vega is a high-end GPU.
  • RX: GPUs for entry-level and mid-tier computers.

By glancing at the RX number, you can identify which GPU was introduced more recently. The model is newer if it is higher. That's something we'll bring up again: A higher number does not imply more power in AMD GPUs. Instead, it denotes when it was first launched.

Some models will have an extra letter after the number (s).

  • XT Graphics: An upgraded version of an existing GPU with the same moniker.
  • HD: Older series are being phased out.
  • R: This is another older series that is being phased away.

NVIDIA graphics cards

NVIDIA's product classification approach is a little different. You'll begin by determining the letter designation. A GT graphics card is designed for everyday usage, but a GTX graphics card is designed for high-end gaming.


The pinnacle of gaming performance GPU


Gaming-specific graphics cards, ranging from entry-level to high-end.


Low-cost discrete graphics cards.

The numbering sequence reflects the GPU's age. The 30 series, for example, is newer than the 20 series. A higher series number shows how the graphics cards are with lower-numbered GPUs, much as it does with AMD graphics cards.

A GTX card, on the other hand, outperforms a GT, regardless of the model number. With the RTX branding, NVIDIA raised the bar even higher in performance. Keep in mind that some of these, notably the 30-series cards, are quite costly and in limited supply at the time of writing.

The letter designation at the end denotes specific capabilities.


It indicates that it will outperform a GPU with a similar designation. The GeForce GTX 1660 Ti, for example, surpasses the GeForce RTX 1660.


Previously represented a "mobile" or laptop GPU, but is no longer in use.


This symbol no longer exists, but it once denoted a "mobile" or laptop GPU.

Graphics cards from AMD and NVIDIA are available for desktop and laptop use.

Graphics cards from AMD and NVIDIA are available for desktop and laptop use. Previously, graphics cards for laptops were tagged with an 'M' to denote that they were mobile GPUs. Both firms' most recent graphics cards have eliminated the mobile moniker, especially as they strive to bridge the gap between laptop and desktop GPUs.

Price ranges and suggestions to bear in mind: 

AMD and NVIDIA both provide excellent graphics cards for regular usage and gaming. Because the price of a graphics card dedicated to gaming tends to mirror its power, this is not necessary to acquire one if you are not interested in running games at the maximum settings and want the best performance for your money.

We suggest the AMD RadeonTM RX 5600 XT and NVIDIA GeForce GTX 1660 Ti as general-purpose graphics cards. You can still get by with those two graphics cards for gaming, but you should consider upgrading to the AMD Radeon RX 6800 XT and one of NVIDIA's GeForce RTX 20-series cards.

Choosing a graphics card is one of the most challenging aspects of purchasing a new computer, partly because it is one of the most vital components, and you want to get it right the first time. In addition, if you're new to GPUs, there's a lot of jargon to learn.

You should generally replace your graphics card every 4 to 5 years. However, a high-end GPU could last a little longer. While affordability is important, you need to think about how much performance and memory you require. Also, keep in mind that your computer's CPU could need to be replaced. After all, the powerful GPU is only as good as its accompanying CPU. Get Best Graphic Cards of your choice from now.
