14 DAY TRIAL // Although Nvidia hasn't officially announced any specific date for the GTX 590 launch, most of us assumed that the card would be released on March 22, as so many rumors seemed to point out to that particular date. However, it now appears that the GTX 590 will be actually released two days later, on March 24.
This latest report comes from the Expreview website and claims that, according to some industry sources, the card's launch has been postponed two days and is now expected to arrive on March 24.
The specific reasons behind this decision aren't clear at this moment, but considering that the release date was delayed only by a couple of days it seems like everything is going pretty well with the GTX 590.
Other details regarding the graphics card are not available at this time, but from previous leaks we do know that Nvidia's upcoming dual-GPU solution will be based on two GF110 GPUs, the same core used to power the GTX 580.
This means that the card will feature no less than 1024 CUDA processors, 128 texturing units, 96 ROP units as well as dual 384-bit memory buses. Each one of these will be connected to 1.5GB of video buffer.
Given the high power consumption of the GPUs, Nvidia was forced to downclock the GF110 cores used inside the GTX 590, and rumors suggest that these will be run at 612MHz while the GDDR5 memory runs at 855MHz (3420MHz effective).
To further limit the power consumption of the card, and get it to fit inside the 375W thermal envelope, Nvidia has selected the best chips it could find for the GTX 590 and these are required to operate at the default speed using only 0.96V.
The temperatures of the card are kept in check by using a cooling solution similar to that of the Radeon HD 6990, which uses a centrally placed fan to basically split the PCB into two distinct sections.
