CrossFire’s DVI-link here to stay

CrossFire uses an external link for communicating between the two graphic cards. DVI-link is the name of the interface for the simple reason it works via the DVI-ports on the graphic cards. How the system works was discussed in our review of the Radeon X1000-series. There we told you that the Radeon X1300 actually works in Crossfire without the DVI-link, simply because PCI Express has enough bandwidth to cover the data as these low end card can’t send as much data as the more powerful siblings. Even if the PCI Express bandwidth will be doubled in a CrossFire-system when ATi goes to dual x16 PCIe channels instead for the dual x8 it uses today it won’t be enough for even handling Radeon X1600 in CrossFire.

This was revealed by ATi’s David Nalasco in an interview with T-Break.com which means that CrossFire’s DVI-link is most likely here to stay, most likely until the launch of ATi’sR600.
