The folks over at TechPowerUp have recently released a GPU-Z screenshot showing the official hardware specifications of AMD's dual-GPU Radeon HD 7990 graphics card, codenamed "New Zealand."

According to the architectural specifications at hand, the card features completely-unlocked 28 nm "Tahiti XT" GPUs with 2048 stream processors each, an AMD-rebadged PLX PEX8747 PCI-Express 3.0 48-lane bridge chip and a shroud that carries the "GHz Edition" badge.
 
In terms of performance specs, the card features a 1.0GHz core clock, 1250MHz memory speed and a total of 6GB GDDR5 memory (3GB usable / per-GPU). In terms of heat ventilation, it appears AMD has borrowed a design strategy similar to Nvidia's GeForce GTX 590 dual-GPU, where a 70mm fan is placed in the middle of the PCB between two heatsinks cooling off both GPUs on the left and right. Of course, many users of the previous-generation Radeon HD 6990 dual-GPU have complained of high noise and "buzzing" issues at decibel levels that barely tip over the scales in terms of acceptability. Nevertheless, AMD hopes its new heatsink design should alleviate consumer woes surrounding these noise complaints.

 

AMD's "New Zealand" dual-GPU beast will be powered by two 8-pin PCI-Express power connectors and will feature one dual-link DVI connector and four mini-DisplayPort connectors. Hard launch is expected on Tuesday, April 17th.
