But a high-end card provides more power than most people really need. People who use their computers primarily for email, word processing or social media can find all the necessary graphics support on a CPU with integrated graphics. A mid-range card is sufficient for most casual gamers. People who need the power of a high-end card include gaming enthusiasts and people who do lots of 3-D graphic work. A good overall measurement of a card's performance is its frame rate, measured in frames per second FPS.
The frame rate describes how many complete images the card can display per second. The human eye can process about 25 frames every second, but fast-action games require a frame rate of at least 60 FPS to provide smooth animation and scrolling.
Components of the frame rate are:. The graphics card's hardware directly affects its speed. These are the hardware specifications that most affect the card's speed and the units in which they are measured:. The computer's CPU and motherboard also play a part, since a very fast graphics card can't compensate for a motherboard's inability to deliver data quickly.
Similarly, the card's connection to the motherboard and the speed at which it can get instructions from the CPU affect its performance.
Many CPUs have integrated graphics capabilities and function without a separate graphics card. These processors handle 2-D images easily, so they are ideal for productivity and internet applications. Plugging a separate graphics card into one of these systems overrides the onboard graphics functions.
Some people choose to improve their graphics card's performance by manually setting their clock speed to a higher rate, known as overclocking. People usually overclock their memory, since overclocking the GPU can lead to overheating.
While overclocking can lead to better performance, it also voids the manufacturer's warranty. Sign up for our Newsletter! Mobile Newsletter banner close. Mobile Newsletter chat close.

Early 3D games that predate the widespread availability of graphics cards, like Ultima Underworld, ran entirely on the CPU. UU is a useful reference case for multiple reasons — it had a more advanced rendering engine than games like Doom, with full support for looking up and down, as well as then-advanced features like texture mapping.
But this kind of support came at a heavy price — many people lacked a PC that could actually run the game. Ultima Underworld. Image by GOG. In the early days of 3D gaming, many titles like Half-Life and Quake II featured a software renderer to allow players without 3D accelerators to play the title.
But the reason we dropped this option from modern titles is simple: CPUs are designed to be general-purpose microprocessors, which is another way of saying they lack the specialized hardware and capabilities that GPUs offer. A modern CPU could easily handle titles that tended to stutter when running in software 18 years ago, but no CPU on Earth could easily handle a modern AAA game from today if run in that mode.
Not, at least, without some drastic changes to the scene, resolution, and various visual effects. As a fun example of this: The Threadripper X is capable of running Crysis in software mode, albeit not all that well. More complex visuals, like you would find in high-definition games, require more complex and quicker GPUs to accommodate the stream of data.
You can expand your PC by adding additional cards internally. Some motherboards have expansion slots allowing users to add more than one graphics card. The intention is to link two of the same graphics cards together. SLI works by increasing the available processing power for graphics usage. Users will need a motherboard ready for SLI or Crossfire to be able to use these technologies.

Graphics cards are not just useful for gamers. Discrete graphics cards can also significantly improve quality of experience for users of photo and video editing programs as they will improve the speed in which images can be rendered. Some users have allegiances to a particular brand but each will do the same job. AMD also produce some integrated graphics options, as well as the current market leader Intel. Current graphics cards also contain RAM memory. Memory is important on a graphics card as it allows users to play games at higher resolutions.
Ideal for those using games which contain very large texture packs. A minimum of 1GB memory is recommended for gamers, but this needs to be balanced out with other aspects of the card and the resolution you play a game at. Graphics cards can support multiple monitors. However the number is determined by the GPU and the number of outputs available. Check the specs of each individual graphics card to find out how many monitors it could support.
These GPUs add processing power at the cost of additional energy consumption and heat creation. Discrete GPUs generally require dedicated cooling for maximum performance.
Two decades ago, GPUs were used primarily to accelerate real-time 3D graphics applications, such as games.
This realization gave rise to the general purpose GPU era. Now, graphics technology is applied more extensively to an increasingly wide set of problems. Video games have become more computationally intensive, with hyperrealistic graphics and vast, complicated in-game worlds. With advanced display technologies, such as 4K screens and high refresh rates, along with the rise of virtual reality gaming, demands on graphics processing are growing fast.
GPUs are capable of rendering graphics in both 2D and 3D. With better graphics performance, games can be played at higher resolution, at faster frame rates, or both. For years, video editors, graphic designers, and other creative professionals have struggled with long rendering times that tied up computing resources and stifled creative flow.
Now, the parallel processing offered by GPUs makes it faster and easier to render video and graphics in higher-definition formats. All while on a sleek lightweight laptop.
Because GPUs incorporate an extraordinary amount of computational capability, they can deliver incredible acceleration in workloads that take advantage of the highly parallel nature of GPUs, such as image recognition.
FPGA vs. Intel has long been a leader in graphics processing technology, especially when it comes to PCs. With our first discrete GPU for PCs based on Intel Xe architecture, you get even more performance and new capabilities for enhanced content creation and gaming.
