Graphics cards, sometimes called video cards, manage how your computer renders video, whether you're playing games on their highest settings or playing in VR and 4K. For gamers, graphics cards are among the first pieces of hardware to consider for building or buying a computer, and yet, understanding the differences between different video cards can be daunting, so it's worth brushing up before buying.
The Asus GeForce RTX 2060 Graphics Card offers high-performing video on up to three screens, and it’s the perfect pick for gamers.
A graphics card is the piece of hardware inside a computer responsible for rendering images, video and general display needs. Graphics cards can determine your computer's refresh rate — or how many times your computer screen refreshes per second. Cards with higher refresh rates offer better and smoother displays than those with lower refresh rates.
Many low-end computers feature simplified video hardware such as integrated video chipsets instead of video cards. However, graphics cards are essential for gaming and other high-performance tasks like computer-aided design or animation projects.
For the vast majority of graphics cards shoppers, gaming is the priority. Even low-end graphics cards can help you run some games, but it's essential to consider what games you hope to play or what programs you hope to run to make sure you choose the best card. Newer games have higher hardware requirements and may require higher-end graphics cards. Be sure to check the requirements of any game or program you plan to use before picking out a video card.
Graphics cards also take up physical space inside your computer and on your motherboard. Check your computer's motherboard to ensure there's a port for graphics cards. In addition, check that there's enough room to fit the video card when it's placed on the motherboard — especially if you have a small computer case.
While the term graphics processing unit is sometimes used interchangeably with graphics card, it refers explicitly to the hardware that renders the video, rather than referring to the fans, random access memory or other included hardware pieces on a video card. Nvidia and AMD are the two brands that offer GPUs, and each company offers a wide range of cards with varying performance.
The clock speed offered by a graphics card is how frequently the card’s cores can perform new tasks. Graphics card clock speed is measured in megahertz, not unlike that of a computer’s processor, and it runs at a varying level. Most graphics cards advertise a “boost clock speed,” which is how fast the cores refresh when running at the maximum workload. A faster clock speed results in better refresh rates and improved performance overall.
In addition to the RAM included in computers, graphics cards feature their own RAM units that are dedicated to video output tasks — often called VRAM. Like regular RAM, VRAM comes in increments of 2 gigabytes, most commonly seen in 4GB, 6GB and 8GB configurations. RAM types in video cards also vary in quality and performance based on how old they are. In order from oldest to newest, common RAM types include SDRAM, GDDR5, GDDR5x and GDDR6.
Cheap graphics cards can cost as little as $60. However, you can expect to spend $150-$700 on most mid-tier and high-end graphics cards, with performance versions sometimes costing even more.
A. Yes. Using two graphics cards at once can boost performance, but there are a few requirements. Both graphics cards must be from the same brand, and they must be dual-card compatible. In addition, your motherboard needs multiple graphics card slots. You’ll also need to use either AMD’s CrossFire or Nvidia's SLI to use the cards together.
A. The number of fans in a video card doesn't necessarily matter. However, those with just one fan may have to work harder to keep the unit cool, thus running louder. Some people prefer graphics cards with two or three fans to minimize the volume and reduce the risk of the card overheating even more.
