AMD Radeon HD 7990 to have 6GB GDDR5
AMD's Radeon HD 7990 dual-GPU card is expected to arrive in late Q1 2012. This model will feature a total of 4096 stream processors and a whopping 6GB of GDDR5 memory. The HD 7990 will arrive by the end of the first quarter of 2012, according to a slide published by Donanim Haber, and will most probably be built using two Tahiti XT graphics cores which will be linked together via CrossFireX.
If AMD will indeed go for the Tahiti XT, this could mean that the card will include 62 Compute Units for a total of 4096 stream processors, 256 texture units and 64 ROP units.
Each one of the two GPUs will also feature a 384-bit wide memory bus that will be connected to 3GB of GDDR5 video buffer, delivering a whopping 6GB of VRAM on a single graphics card.
The clocks that the memory chips or the two GPUs will run at are unknown, but most probably AMD will have to go lower than the 925MHz/1.375GHz (5.5GHz effective) frequencies used for the HD 7970 in order to decrease the power consumption and the heat output of this dual-GPU monster.
