It hasn’t been long since the AMD unveiled its newest range of graphics cards; the Radeon R9 280X, Radeon R9 270X and the Radeon R7 260X and since this release, a lot of web pages can be seen doing their reviews on the three cards.
The testing by HardwareCanucks revealed that Radeon R9 280X was CrossFire compatible with the Radeon HD 7970. This has surely brought some good news for the users of HD 7970. The users who were previously hoping to include a Tahiti to the CrossFire can satisfy their wish by the Radeon R9 280X addition which is comparatively cheaper than the HD 7970 models available online. Moreover, the Radeon R9 280X option falls closer to the Tahiti as the Radeon R9 280X was actually based on the Tahiti XT chip which features 2048 Cores and 32 ROPs. These are available in different variations in the form of non reference models. Though they are more expensive, there is no reason to believe that they are better performers because they more or less house the same specs.
For getting the CrossFire to work between your Radeon R9 280X and Radeon HD 7970, all you have to do is get hold of the newest card. With a single plug-in action you’ll be ready to go once you attach it with the CrossFire Bridge. Though the connection of these cards requires no installations and updates and this brings ease of use for the users, there is still one backdrop. With the use of CrossFire, the cards will have to synchronize their clocking speeds and for this one of the cards will have to stoop down to the level of the card with the lower speeds.
The Radeon R9 280X is not the only highlight of the AMD’s latest release; the R9 270X too is pretty much capable of CrossFireX comparability and is based on the Pitcairn XT die codenamed to Curacao XT. While the R9 270X allows compatibility with the Radeon HD 7970 GHz edition, the R9 260X is compatible with the Radeon HD 7790.
