NVIDIA is planning a launch of the upcoming dual-GPU video card in the next month. The GeForce GTX590 should launch to duke it out against AMD's upcoming Antilles, otherwise known as the Radeon HD6990.
The GTX590 will feature two GF110 cores with a total of 1024 CUDA cores, 3027MB of GDDR5 memory, dual 384-bit memory buses, 128 texture units and 96 ROPs. Based on features alone, this effectively doubles the specifications of NVIDIA's GeForce GTX580.
NVIDIA is said to have included all of the CUDA cores but will reduce the stock clock frequencies and voltages to give it improved power consumption numbers. The TDP has not been announced for the GTX590 yet, but be sure it will be a beast, the GTX580 is rated at 244W just to give you an idea... for those who live on the bleeding edge, they won't care. The thing could use 500W and it will still be the talk of the web.
Get ready to don your green suit, not even a month until release!
