With the launch of the Cayman series of video cards, AMD has completed their lineup for 2010 just in time for Christmas. While some might consider the HD 6970 to be late the fact is the Cayman series is priced to move at $370 and $300 for the HD 6970 and HD 6950. The HD 6970 is the fastest AMD card on the market besides the dual-chip 5970, but what if you want even more graphics power than a single card can provide?
The solution was first introduced with the 3DFX Voodoo 2 cards. The solution if you might remember was to pair two cards along with a third “2D” card to improve performance. ATI introduced Crossfire with the launch of the X800 series back in 2004. The problem was the need for additional computer components including a back “Dongle” and set in a Master/Slave solution, making the solution a bit problematic as the Dongle had issues of its own. One good push was all it took to unseat the dongle.
With the advent of the X1950 Pro card from AMD, things changed for the better. The dongle was replaced by CrossfireX bridges in a solution that was similar to NVIDIA’s SLI solution. Today Crossfire is part of the video card lineup with AMD having compatible solutions on many AMD and Intel chipsets. With the launch of a new architecture in the form of the Cayman series the most important questions are what scaling does two 6970s get over a single card, what temperatures are reached with two cards in adjacent slots, how the system requirements for running in Crossfire mode are and what are the results.
