A graphics card is a type of display adapter or video card installed within most computing devices to display graphical data with high clarity, color, definition and overall appearance. A graphics card provides high-quality visual display by processing and executing graphical data using advanced graphical techniques, features and functions.
A graphics card is also known as a graphics adapter, graphics controller, graphics accelerator card or graphics board. By: Justin Stoltzfus Contributor, Reviewer. Still, other cards may have inputs for video editing and other advanced tasks. Laptops, tablets, and even smartphones, all have video cards, albeit smaller and most often non-replaceable.
Each motherboard supports only a limited range of video card formats, so be sure to always check with your motherboard manufacturer before making a purchase. Many modern computers don't have video expansion cards but instead, have onboard video GPUs integrated directly onto the motherboard. This allows for a less expensive computer but also for a less powerful graphics system. This option is wise for the average business and home user not interested in advanced graphics capabilities or the latest games.
Most motherboards with onboard video allow BIOS to disable the chip in order to make use of a video card installed to an expansion slot. Using a dedicated video card may improve overall system performance because it includes its own RAM , power regulators, and cooling so that the system RAM and CPU can be used for other things.
In Windows, the easiest way to see what video card you have is to use Device Manager. You can find it listed under the Display adapters section. Another way is through a free system information tool like Speccy , which identifies the manufacturer, model, BIOS version, device ID, bus interface, temperature, amount of memory, and other video card details.
Opening the computer case is another option, allowing you to see the video card for yourself. Doing this is, of course, required if you plan to replace the card, but just identifying information about it is best done through the software mentioned above. Like all hardware, a video card requires a device driver in order to communicate with the operating system and other computer software.
The same process you'd use to update any sort of hardware applies to updating a video card driver. If you know what driver you need, you can go directly to the manufacturer's website and manually download it. This is always the best way to get drivers because you can be confident that it's stable and doesn't contain any malware.
If you don't know the specific video card driver that you need, or if you'd rather not download and install it manually, you can use a free program to automatically detect the driver you need and even download it for you.
You may experience a black screen if you inserted the video card while the power wasn't completely off. Its gaming performance credentials are undoubtedly impressive, but what makes the RTX our pick for the sensible PC gaming connoisseur is the entire Nvidia ecosystem underlying the RTX stack today.
DLSS is a neat trick for improving performance, with only a nominal loss in clarity, and other features such as Broadcast and Reflex go a long way to sweetening the deal. And it gets kind of close, too, with 4K performance a little off the pace of the RTX —and all for one-third off the asking price. For that reason, it's simply the better buy for any PC gamer without any ulterior motives of the pro-creator variety.
But there's a reason it's not number one in our graphics card guide today, and that's simply due to the fact it's not that much better than an RTX , and sometimes not at all.
Yet, inevitably its ray-tracing acceleration lags behind the competition. With that in mind, for raw gaming alone, the RX XT is a cheaper alternative to the RTX is still a victim to its own extreme price tag.
This colossal graphics card is supremely powerful but far more fitting of Titan credentials than GeForce ones. It's not built with your average gamer in mind. Instead, it's targeting creative professionals and compute-intensive application acceleration, and that's why it doesn't come with your average price tag, either. As immense in price tag as it is in stature, the question on everyone's lips is: Is it worth it?
For gamers, no. It's just not much quicker than the RTX But for pro-creators, for whom time is money and where lower render time has a direct correlation with how much they can earn, that's where the RTX comes into its own. It's for that reason that we've placed this card near the bottom of our list, but since we know PC gamers will undoubtedly spend ungodly quantities of cash to save face and ensure bragging rights, it's still worth a mention.
After all, it is the most powerful gaming graphics card on the planet right now, whether it's a great deal or not. As the only one of the AMD RX series cards to launch without undercutting a direct Nvidia Ampere rival, the straight RX feels as though it's almost been cut adrift.
It's a strange situation because historically, we've always been keen to recommend the second string of any Radeon release. AMD tends to launch main series cards in pairs, one with the full might of the new GPU and a secondary card with a slightly stripped back chip.

Normally they perform at a similar level for a lot less cash. Except for this time, the performance gap is relatively large, and the price difference is not great enough to negate the issue. Sure, the RX does sometimes outperform the cheaper Nvidia card, but for the money, you'd surely want the only marginally more expensive RX XT because it's much faster.
This allows the graphics to take precedence over peripherals which demand fewer resources, such as sound cards or network adapters. Two companies currently implement a system installing multiple graphics cards in a single machine. You can identify a dual-card configuration by the bridge or cable link between two identical-looking cards within the PC. Today, graphics cards often utilize expansion slots on the motherboard specifically designed to meet the higher demands a graphics card places on the system bus.
In the early s, the accelerated graphics port, or AGP, appeared on motherboards to accommodate graphics cards only. PCI Express slots come in various speeds and can work with non-graphics cards.
