AMD is preparing to release the Southern Islands / HD 7000 flagship, codenamed New Zealand, to be branded Radeon HD 7990. As expected, the 7990 will be a dual-GPU card, based on 2 x Tahiti.

In essence, HD 7990 will be 2 x HD 7970 downclocked, Crossfire'd and cramped into a single GPU. There will be a total of 48 CU covering 4096 SP and 256 TMU. HD 7990 will feature a total of 6GB GDDR5, 3GB per GPU. The clock speeds are down mildly from the HD 7970, settling at 850 MHz core and 5 GHz memory. Judging by these clock speeds, it is likely the HD 7990 will ship with a ~375W TDP and the same non-standard 2 x 8-pin power connectors configuration featured in HD 6990 and GTX 590.

The 7990 is expected to release in early April, following shortly after the release of GeForce GTX 680 later this week. On release, HD 7990 will take over the fastest graphics card crown, at least until NVIDIA challenges with a dual-GK104 chip, possibly GTX 690. HD 7990 will be in with a fighting chance of becoming the most expensive reference gaming/consumer graphics card at release, eclipsing GeForce 8800 Ultra's $829.
