Today has been a day strictly about video cards, or so it seems. We now have a good idea what AMD's upcoming 7990's specifications should amount to. We also know basically what the nVidia GTX 680 is capable of. So, AMD needs to fire back with something to top it. Well, they hope that the 7990 is just the thing. Unfortunately, it may also eclipse the nVidia 8800 Ultra as the most expensive graphics card ever to be released in the process.

The rumored specifications of the HD 7990 will in essence be 2 x HD 7970 downclocked, Crossfire'd and cramped into a single GPU board. This means it will feature 48 CU covering 4096 SP and 256 TMU. It will have 6GB of total vRAM. It's clocks will be 850 MHz core and 5 GHz memory. An educated guess would place it at a TDP of ~375W and require two 8-pin power connectors. It is set to release in early April and regain the crown as the single fastest GPU. Well, at least until nVidia fires back with a dual-GK104 chip, possibly called the GTX 690.
