There is a lot of testing and coding required for a game to scale properly on setups like these, and developers know that a tiny subset of the population is rocking multi GPU configurations therefore, they do not even bother with doing the necessary work. ![]() The results and gains of a multi GPU setup using Crossfire can be somewhat complicated as not all games run at double the performance, nor do you get double the frame rates. The Slave-Master configuration remains the same however, each card renders separate frames and combines them to form the image you see on the screen. As the name suggests, this type of rendering renders every alternative successive frame. Alternate Frame RenderingĪnother graphics rendering technique done by cards in Crossfire is alternate frame rendering. Crossfire’s one-way graphics card pools its resources and gives you more performance. The master card, after compiling the resulting frames, display the images on the screen. In Split Frame rendering, every card is assigned the work on different parts of the frame to be rendered and sent to the master card to be compiled. There are two modes of graphics cards in Crossfire that work with each other. The Master cards will receive the processing output from the slave cards and create the resulting image. This means that one card will act as the Master card while all the following cards will serve as the slave cards. ![]() What Crossfire does is that it pools the resources of the two AMD GPUs and combines the processing power of the GPUs in a Master-Slave configuration. Unlike SLI, you also do not need a connector to pair them together as crossfire cards can communicate using the PCI slots. Pair the lowest-end AMD GPU with the flagship one, and they are going to work as expected. As long as you have two AMD graphics cards that belong to the same architecture family, you can go crazy. Meanwhile, AMD’s multi GPU solution is a lot more “loosey-goosey” and, in my opinion, more consumer-friendly. While Nvidia only allows you the freedom to pick between different card vendors and clock speeds but restricts you to the same graphics card. You cannot SLI them as they are not compatible with each other. ![]() Suppose you have two Nvidia GPUs like the GTX 1070 and the GTX 1080. So, in theory, you can Crossfire an RX 550 with an RX 580 and get some performance increase. However, you are free to mix and match when it comes to clock speeds and memory size.

However, there are certain limitations, and you cannot just pool any graphics card willy-nilly. Question 8: What is the benefit of CrossFire? What Is AMD CrossFire?ĪMD’s Crossfire is the technology that allows two AMDs GPUs to be used in tandem, thereby pooling their resources and increasing the gaming performance of the PC.
