This processor is an incredibly complex chip developed with decades of research and experimentation. Historically, these two companies have battled for leadership in the GPU market, constantly forcing each other to innovate to the benefit of consumers. Both have strengths, and both offer solid options. These companies take the chips designed by either AMD or Nvidia, and create their own graphics card using this technology. Think of it as a car; the engine is created by AMD or Nvidia, but the rest of the car, including the body and the cooling, are designed by the company that manufacturers the card itself.
Each GPU manufacturer brings their own unique design choices and technologies to the table, which results in plenty of options to choose from. There are other considerations too, such as cooling, clock speeds, and aesthetic design that can impact performance, but if you buy an RTX , you know the fundamental capabilities of the card regardless of the manufacturer.
The most popular and powerful GPUs are those in its series RTX , , or , with performance capabilities increasing with the number. Nvidia has a wide range of GPUs covering the low-end to the very high end of the consumer GPU market as well, not only flagship products.
Here are some of the most relevant Nvidia gaming GPUs as of late As you can see from the charts above, there are a few specifications that you will want to keep in mind as you look to purchase a GPU.
These benchmark comparisons will allow you to see how different versions of the same GPU compare to each other, and to other versions. As with all powerful hardware that uses electricity, GPUs generate a lot of heat, and require sufficient cooling to run reliably and at peak performance. Most graphics cards will include a power supply recommendation, usually with recommended watts such as watts. This can be important in both desktops and laptops, where thermals become a high priority given space constraints.
Note that as you are designing your PC or choosing a GPU upgrade, you will also want to research how hot a given graphics card runs at maximum power.
Usually this is a mix of six-pin and eight-pin connectors, but this can vary. Discrete GPUs utilize a special type of memory to store the data needed to ultimately display information on a screen. The amount of video random access memory VRAM in your GPU is important for high-performance games that use large amounts of data to construct the complex images on screen.
This is also a factor when running multiple displays, especially if they are higher resolution or refresh rate. RAM bandwidth is another important metric to consider as well. GPUs vary, in how many physical slots they fill, between single, double, and even triple slot configurations. This means you also need to consider any other components that you want to plug in alongside the GPU, especially if they are going to use a PCIe slot. You also need to ensure your case is large enough to support the components you are installing.
Insufficient space can result in improper cooling, which can lead to decreased performance. If space constraints are a concern, there are GPUs designed specifically to have a smaller profile.
It needs to connect to a motherboard, and a display, or multiple displays, to function. VGA is an older, legacy connection that might still be available on some displays, but is quickly fading into obscurity. The differences between all the different display connections is a topic deserving of its own article. Suffice it to say you will need to make sure that your chosen graphics card supports enough connections for all the monitors you want to plug into your PC, and that they are the right connections.
Note that in many cases you can buy adapters to convert a connection on the graphics card to one that a display can accept, though this can limit access to features like higher resolutions and refresh rates. You will need to double-check the specifications to make sure a given graphics card can support as many monitors as you want to connect, and that the connections are compatible between your GPU and your displays. Some graphics cards can be connected to run in parallel with additional cards, which can provide serious boosts in performance for demanding games.
This configuration is not as common as it used to be. Hopefully you have a better sense of what to look for in a GPU. If you do not want to run current computer games on your notebook but only graphically undemanding applications, like office, internet, or videos, a GPU integrated in the mainboard e. On-board models should also be able to run the one or other older game. Users who want to run multimedia applications and games should definitely buy a system with a dedicated graphics card with or MB video RAM.
But, an on-board GPU without dedicated memory will suffice pure Office use. Further information about mobile graphics cards are available in our comparison of mobile graphics cards.
