![]() ![]() The same feature applies to video cards built on the basis of two video processors (recognized by the suffix "X2" in the name), with the declared total amount of video memory, in fact, such a card is the equivalent of a card with half the amount of video memory and is properly recognized in 3D applications. ![]() When combining cards into an array, each works with its own copy of a set of textures and geometric data, so the actual amount of video memory is equal to the smallest amount of video memory available to each of the video processors working together, i.e., for example, when combining two cards with video memory sizes of 512 MB and 256 MB we get an effective amount of video memory of 256 MB. The modern version of CrossFire technology is officially called CrossFireX, sometimes CrossFire is abbreviated to "CF" for convenience (do not confuse it with CompactFlash).Ĭombining a discrete (separate) with a built-in chipset is called Hybrid CrossFire and is accompanied by a number of additional restrictions, this technology is dedicated to. you can combine four single-processor cards or two dual-processor cards) is that video cards belong to the same generation, for example, you can combine 4870X2 with 4870 or 4830 with 4870, but combining, say, the Radeon X1950 with the HD3850 will not work in any way. However, this variant of merging was not developed, and later ATI, like nVidia in its technology, began to use external bridges to exchange information between cards combined into an array.Ī prerequisite for combining two or more cards into an array (currently up to four GPUs, i.e. The initial implementation of this technology (for the X800 and X1800 series chipsets) meant the use of a so-called "master card" and an external Y-cable with a special chip that combines image fragments transmitted by two cards into a single picture. ![]() CrossFire is a multi-GPU technology from ATI (currently a division of AMD) that allows multiple Radeons to be combined to work on a single 3D image. ![]()
