More AMD "RD790" Details Revealed
 

The RD790 is the successor to AMD’s previously released 580X chipset, formerly known as CrossFire Xpress 3200. This time around AMD is only releasing a new north bridge. The upcoming RD790 is expected to pair with the existing SB600 south bridge.

Nevertheless, the RD790 has plenty of PCI Express lanes to go around. AMD has equipped the RD790 with 42 PCI Express lanes for plenty of expansion capabilities. Thirty-two PCI Express lanes are dedicated to two PCIe x16 slots for CrossFire operation. These lanes can be further divided to deliver four PCIe x8 slots as well. PCI Express 2.0 will be supported as well.
