A key part of any computer<\/strong>, the graphics card<\/strong> plays an essential role in how every PC<\/strong> works. This important component is responsible for the display<\/strong> of all graphical information on your monitor<\/strong>. Its job is to process graphics data to provide a usable output for the user<\/strong>.\u00a0<\/span><\/p>\n

Definition and purpose<\/b><\/h2>\n

The graphics card<\/strong> connects to the screen<\/strong> (using a VGA, DVI, USB or HDMI connector<\/strong>). Its main function is to reduce the workload on the processor<\/strong> in your computer<\/strong>.<\/span><\/p>\n

More specifically, this part handles the processing of graphics<\/strong> data in order to power:<\/span><\/p>\n

    \n
  • Operating system visual features<\/strong><\/span><\/li>\n
  • Photo and video editing or image<\/strong> processing software.<\/span><\/li>\n
  • Running video games (which require a powerful graphics card<\/strong>).<\/span><\/li>\n<\/ul>\n

    A quick tip: remember to update the drivers<\/strong> for your graphics card<\/strong> regularly to avoid<\/strong> issues such as:<\/span><\/p>\n

      \n
    • Screen flickering<\/span><\/li>\n
    • Frozen images<\/span><\/li>\n
    • Black screens<\/span><\/li>\n
    • BSOD (Blue Screen Of Death<\/strong>)<\/span><\/li>\n<\/ul>\n

      A graphics card is a small computer<\/strong> inside your PC<\/strong>. It has its own processor<\/strong>, its own RAM<\/strong> and even its own cooling<\/strong> system (fans).<\/span><\/p>\n

      Depending on its power<\/strong>, a graphics card<\/strong> can output images at high<\/strong> resolutions<\/strong> (8K, 4K, 1080p, 720p<\/strong>). So if you want high image quality, choose a powerful card<\/strong>.<\/span><\/p>\n

      Key criteria when choosing a graphics card<\/b><\/h2>\n

      On the market you\u2019ll find different brands offering graphics cards (AMD, NVIDIA, INTEL<\/strong>). It\u2019s not easy to navigate such a huge choice, so here are some key factors to focus on:<\/span><\/p>\n

        \n
      • How you plan to use the graphics card<\/strong>: office work, multimedia, gaming, or professional workloads (accounting, CAD, architecture software and so on).<\/span><\/li>\n
      • The physical size of the graphics card, which must be compatible with your case<\/strong><\/span><\/li>\n
      • The budget<\/strong> you\u2019re prepared to invest<\/strong><\/span><\/li>\n
      • Power consumption<\/strong>, usually given in watts<\/strong><\/span><\/li>\n
      • Available memory and the supported frequency<\/strong><\/span><\/li>\n
      • Compatible cables<\/strong>: VGA for connecting to a monitor, S-Video for a TV or projector, HDMI for HD screens, DVI for monitors and TVs, DisplayPort, and so on.<\/span><\/li>\n<\/ul>\n

        The graphics card<\/strong> connects to the motherboard<\/strong> via a PCI EXPRESS<\/strong> slot. This allows the central processor<\/strong> to communicate freely with the card\u2019s components.\u00a0<\/span><\/p>\n

          \n
        • The graphics processor or GPU<\/strong>: this is the processing unit that handles graphics data.\u00a0<\/span><\/li>\n
        • RT cores<\/strong> (Nvidia only): these are small processors dedicated to Ray Tracing calculations (a graphics technique that improves shadow rendering).\u00a0\u00a0<\/span><\/li>\n
        • Video memory or VRAM<\/strong>: this part handles image data. It processes system information and display output. The latest models can reach 24 GB of VRAM.<\/span><\/li>\n
        • The BIOS<\/strong>: this is firmware stored in the ROM that contains all the essential data needed for the graphics card to start up.<\/span><\/li>\n<\/ul>\n

          Types of graphics cards<\/b><\/h2>\n

          GPU makers (AMD, NVIDIA, INTEL) and board brands (ASUS, EVGA\u2026)<\/b><\/h3>\n

          To get the best possible performance<\/strong>, you need to make an informed choice<\/strong>. There are real differences between graphics cards<\/strong> depending on the GPU manufacturer. The main GPU makers are AMD<\/strong> and Nvidia<\/strong>. However, they don\u2019t generally sell the finished cards themselves. They mainly design the chip architecture<\/strong> and make their technology<\/strong> available to board partners such as:<\/span><\/p>\n

            \n
          • Asus,<\/strong><\/li>\n
          • Gigabyte,<\/strong><\/li>\n
          • EVGA,<\/strong><\/li>\n
          • \u00a0KFA2<\/strong><\/li>\n
          • \u2026<\/strong><\/li>\n<\/ul>\n

            These manufacturers<\/strong> tweak settings such as frequencies<\/strong>, add more memory and design cooling solutions. The difference therefore lies in how they balance performance<\/strong> and price<\/strong>. Longevity depends on the clock speed, the amount of on-board memory<\/strong> and the cooling system<\/strong>.<\/span><\/p>\n

              \n
            • At NVIDIA<\/strong>: generations of graphics cards<\/strong> are identified by the hundreds digit in the model number. For example, a GeForce GTX 7XX<\/strong> series card was released in 2017<\/strong>. Then came the GeForce 9XX<\/strong> series, released in 2015<\/strong>. In 2018<\/strong>, the GeForce<\/strong> RTX 20XX<\/strong> series arrived. More recently, the green team launched the 3\u2009000<\/strong> series, which is ultra<\/strong> powerful (capable of running games in 4K<\/strong>).<\/span><\/li>\n<\/ul>\n

              One series stands apart<\/strong>: GeForce TITAN<\/strong>. These are seen as the ultimate<\/strong> graphics cards. The latest model in the series is the NVIDIA RTX TITAN<\/strong>. Nvidia also offers cards dedicated to specific workloads, such as the Tesla<\/strong>, Quadro<\/strong> and Maximus<\/strong> ranges.<\/span><\/p>\n

                \n
              • At AMD<\/strong> you\u2019ll find the same generation principle as with NVIDIA<\/strong>. Graphics cards follow a chronological order<\/strong>: Radeon Rx300<\/strong> for 2014<\/strong>, Rx400<\/strong> for 2015<\/strong> and Rx500<\/strong> for 2016<\/strong>. In<\/strong> 2017<\/strong>, however, AMD introduced a new architecture and gave it a new name: Radeon Rx Vega<\/strong>.<\/span><\/li>\n<\/ul>\n

                Graphics card ranges and generations<\/b><\/h3>\n

                As you\u2019d expect, the more recent<\/strong> the release year of a graphics card<\/strong>, the more powerful<\/strong> it tends to be. In general there is around a 20%<\/strong> performance gain with each new generation.<\/span><\/p>\n

                Another way to distinguish graphics cards is by their range<\/strong>. With Nvidia<\/strong>, the higher the reference number, the more high-end<\/strong> the card. For example, a GeForce<\/strong> RTX 3060<\/strong> is less powerful than a GeForce RTX 3080<\/strong> or RTX 3090<\/strong>.<\/span><\/p>\n

                It\u2019s the same idea with AMD<\/strong>. A Radeon RX550<\/strong> is an entry-level model compared with a Radeon RX580<\/strong>. More recently, the naming scheme has changed and we now talk about RX 6XXXX XT<\/strong> or non-XT<\/strong> models.<\/span><\/p>\n

                A GPU<\/strong> runs at a certain number of megahertz<\/strong>, which is the unit<\/strong> used to measure the processing speed of a card<\/strong>. This lets you compare cards within the same range. The higher the clock frequency, the higher the frames per second.<\/span><\/p>\n

                Memory is another way to tell graphics cards<\/strong> apart. This component stores large textures and adds certain effects where needed. The aim is to make the video game<\/strong> sharper and better looking. Today\u2019s gaming cards<\/strong> generally offer between 8 and 11 GB<\/strong> of memory. In terms of cooling, some cards are fitted with dual<\/strong> fans<\/strong>, or even triple<\/strong> fans, for improved durability<\/strong> and performance<\/strong>.<\/span><\/p>\n

                 <\/p>\n

                IGP or integrated graphics processor<\/b><\/h3>\n

                Some CPUs include a small integrated GPU (INTEL, AMD<\/strong>). These work in much the same way as a dedicated graphics card. The difference lies in the power available. They are not powerful enough to run the latest-generation video games<\/strong>. They\u2019re best suited to office work<\/strong>, media playback<\/strong> and web browsing<\/strong>.<\/span><\/p>\n

                Installing a graphics card<\/b><\/h2>\n

                A high-performance graphics card that\u2019s poorly installed will never work properly. Here are a few tips to help you install it successfully<\/strong>:<\/span><\/p>\n

                  \n
                • Remove any protective stickers from the card<\/strong> and the fans<\/strong><\/span><\/li>\n
                • Use a piece of kitchen roll<\/strong> slightly dampened with alcohol<\/strong> to remove any residue<\/span><\/li>\n
                • \u00a0<\/span>Plug the graphics card<\/strong> into one of the PCI Express 16x<\/strong> slots on the motherboard<\/strong>. If there are several slots, choose the top<\/strong> one<\/span><\/li>\n
                • Remove the blanking plates from the case<\/strong>. Secure the card to the case using the brackets and screw it in straight and firmly.<\/span><\/li>\n
                • Connect the card to the PC\u2019s power supply (6-pin, 8-pin, 2x 8-pin\u2026<\/strong>).<\/span><\/li>\n
                • Plug in the cable<\/strong> linking the graphics card to the monitor<\/strong><\/span><\/li>\n
                • Check that the graphics card is detected<\/strong> by the computer<\/strong> (via your operating system)<\/span><\/li>\n
                • Then install the drivers<\/strong>, which you can download<\/strong> free of charge from the manufacturer\u2019s website<\/strong>.<\/span><\/li>\n
                • Run a few tests, ideally using benchmark software<\/strong>, to check the health of your graphics card<\/strong> (performance, temperature and so on).<\/span><\/li>\n<\/ul>\n
