The FirePro V7900 is sized in at the same length as the V7800, which is at 11 inches. AMD's V7900 high-end card does have a maximum TDP of 150 Watts, which is slightly above where the V7800 left off at 138 Watts. However, thanks to AMD PowerTune and its power management abilities, for most workloads the actual power consumption will be less. The FirePro V7900 is equipped with a single PCI-E 6-pin power connector for ensuring adequate power is supplied.
Over the FirePro V5900, the V7900 model boasts support for Framelock and Genlock when used with the FirePro S400 synchronization module. There is also Stereo support for the V7900 when using the add-on connector, which is included with the retail version of the FirePro V7900. While not a new addition, the FirePro V7900 also supports AMD CrossFire Pro.
The FirePro V7800 had two DisplayPort outputs and one dual-link DVI where as the FirePro V7900 just goes with four DisplayPort 1.2 outputs. This graphics card, of course, supports Eyefinity Technology as well to enable using all of these outputs simultaneously.
