As the release of NVIDIA's latest Kepler line-up of GPUs comes ever closer, new rumours of specifications, architecture and release dates are emerging.
The latest rumour, which relies heavily on intelligence from VR-ZONE, claims that the GeForce GTX 680 will feature 1,536 stream processors and, contrary to other reports, these shaders will maintain the double-speed clock system of the Fermi, seeing the 680 core clocked at 705MHz, with the shaders running at 1,411MHz.
The rumour also backs-up previous claims that the new GPU will feature a 256-bit memory bus, as opposed to the 384-bit bus of the GTX 580, however, that reference clock speeds are set at a record-breaking 6GHz, resulting in the same overall bandwidth of ~192.4GB/s.
It's also rumoured that the card with sport four display outputs, stacked dual-DVI, HDMI and DisplayPort; with the PCB expected to be 10 inches long, sitting somewhere between the size of the GTX 560 Ti and the 570, though with a more compact and repositioned fan.
Honestly, the details in this post could turn out to be pure speculation, however, VR-ZONE felt confident enough to provide the date of the expected official announcement, March 12th and, stated that March 23rd was the rumoured date of the product's hard launch into the market.
Head on over to the second half of our previous post, for a little more insight on the expected shader layout of the new Kepler architecture.
