While their new high-end models from AMD in coming, to work diligently in the background when Nvidia came today with new information. Thus one plane supposedly a dual-GPU based on the GF-110 chip.
Whether that is realistic, however, remains questionable. Consumes the new top of GTX 580, based on the already improved GF-110 chip, a good 250 watts. A doubling of the chips would correspond approximately to the doubling of the TDP. So we were already at least 500 watts, which would need such a monster of energy.
That this, however, speaks against the PCIe specifications, is more than clear. Nvidia would need about 300 watts TDP on press to achieve a dual-GPU. In plain language this means that either the clock very much reduced and the CUDA cores or similar would have to be curtailed. could also consider it one hand, the Shrink, but this still seems to be a great distance, because even with the 40nm process has to be able to resolve the problems a few months ago. The picture can be at the locations of power outlets, however, suspect that Nvidia violation of these policies and installed two 8-pin power connectors, which, in combination with the stream via PCI slot up to 375 watts. However, would you then still far below the 500 W 580th two GTX Whether that is truly realistic and GTX 590 card planned or whether it brings a big performance increase, is still in the stars.
