It's been quiet on the AMD front recently, but suddenly the new RD790 has reared its head on the Gigabyte stand this morning. ATI hinted at quad CrossFire in Tunisia, at the HD 2900 XT launch, but nothing has been said since then.
Gigabyte’s AMD Product Manager fully expects quad CrossFire in the (near) future, and the board shown supports four slots: two x16 or four in x8. We can only hope it performs better than the fiasco that was Quad SLI.
This is also with PCI-Express 2.0, which offers twice the bandwidth for the same pin count and a maximum power of 150W. The RD790 is the new chipset and will beat Intel's X38 to market. It also includes support for AM2+ and HyperTransport 3.0 to match AMD's Phenom range.
Naturally, until quad CrossFire arrives you've got the choice of just using just normal CrossFire or simply four graphics cards for eight displays, like Asus has already shown with its Intel 975X workstation board released last year.
The GA-M790-DQ6 is made using all Japanese solid state SMD capacitors (like all DQ6 boards), as well as copper heatpipes, Realtek ALC889a sound and dual PCI-Express Gigabit Ethernet.
Interested in the potential performance benefits of quad CrossFire or think it's yet another excuse to try and pry more money out of us? Let us know in the forums
