14 DAY TRIAL // Leaked information about the upcoming GTX 590 graphics card seems to suggest that Nvidia has established the final specifications of its dual-GPU solution, and, just as previous rumors have suggested, the cores will work at a little bit over 600MHz.
The German HT4U website says that it has managed to find out from sources close to Nvidia that the clocks of the two GF110 GPUs will be set at 607Mhz while the memory will work at 850MHz.
These number support what Sweclockers told us at the end of last week, and make sense considering that Nvidia had to keep the power consumption of the card in check so that it won't run into any thermal problems along the way.
Furthermore, as we know from previous reports, the GPUs used for the GTX 590 are handpicked so that only the lowest leakage cores are selected, and HT4U states that these have to use only 0.96V to work at the designated frequency.
In comparison, the GeForce GTX 570 requires about 1V to function at 732MHz, while the GTX 580 uses 1.06V to reach 772MHz.
From what we know until now, the GTX 590 will use a fully fledged version of the GF110 core, and together, the two GPUs pack 1024 stream processors, 128 texturing units and 96 ROP units.
The graphics card also gets 3GB of GDDR5 video buffer that is connected to the two cores via a pair of independent 384-bit memory interfaces.
As far as its power consumption is concerned, the GTX 590 has a TDP of 375W and, as a leaked Nvidia slide has detailed, the printed circuit board uses a 12-layer, 2oz copper design that holds a 10-phase power supply.
The Nvidia GeForce GTX 590 is expected to be officially launched on March 22, and will feature 3D Surround support and a redesigned rear bracket that packs three dual-link DVI ports as well as a mini-DP output.
