Next month we can expect the launch of AMD's dual-GPU Radeon HD 6990 and according to a new report by
Nordic Hardware there may be a new dual-GPU card from NVIDIA as well. The site heard NVIDIA plans to release the GeForce GTX 590 next month, a new dual-GPU graphics card with two GF110 GPUs, 1024 CUDA cores and 3GB GDDR5 memory. Power consumption is unknown, but given that a GeForce GTX 580 already has a TDP of 244W it won't be pretty.
The new graphics card comes with two GF110 GPUs and NVIDIA has chosen to go all in with the shaders. It goes with the top model of GF110 with 512 CUDA cores, which results in 1024 CUDA cores in total and 2 x 384-bit memory bus.
The reason NVIDIA has chosen to use the maximal number of CUDA cores is that this becomes a more efficient solution than turning of shader blocks and increasing frequencies. GeForce GTX 590 will instead get considerably lower clock frequencies and voltages than GeForce GTX 580 that use a single GF110 GPU. This is a pretty obvious sacrifice considering that GTX 580 is rated 244 watt TDP, with just one GPU.
