|Nvidia GTX 590|
The Nvidia Geforce GTX 590 features two fully enabled GF110 GPUs packed on a single PCB and this sums up to a total of 1024 CUDA cores, or simply 512 per each GPU. The rest of the specs include 2x48 ROPs, 3GB of GDDR5 memory (2x1536MB) paired up with a dual 384-bit memory interface. Due to plain power limitations the card doesn't share the clocks the single GPU GF110 based GTX 580 as it was brought down to 607MHz for the GPU, 1214MHz for shaders and 3420MHz for those 3GB of memory.
Rumors say Nvidia might also release a Nvidia GTX 590 Ti Version with a slight overclock.
