Instead of connecting two CrossFire bridges, you now only need to connect the one when you’re running a pair of Radeon HD 3870s or Radeon HD 3850s in CrossFire. With RV670, the implementation changes again - however, this isn’t as stark a change as the one required when ATI moved from a non-native solution to a native one. The implementation remained the same with the R600 family, where the card required two CrossFire bridges connecting the two cards together. In fact, it wasn’t until RV570, known by many as the Radeon X1950 Pro, when ATI actually included native CrossFire support inside the GPU architecture – we heaped praise on AMD for finally adopting native multi-GPU support.
ATI continually claimed that CrossFire was a natural evolution of something it had been doing for a long time in more industrial applications, like flight simulators, but one couldn’t help but think that the implementation suggested otherwise. CrossFire:When CrossFire first launched, there were many criticisms about the design and the famous CrossFire cable.
