It looks like someone has jumped the NDA gun and released a boatload of benchmarks for the GeForce GTX 680 2GB.

In a leaked slide coming out of the Chinese web-site PCOnline.com.cn, we see an official Nvidia slide listing the GeForce GTX 680 specifications. The GeForce GTX 680 is based on the 28nm Kepler GK104 chip and is said to launch around March 22nd. The GTX 680 features clock speeds of 1006 MHz (base), and 1058 MHz (boost). The memory is clocked at 6 GHz (1500 MHz actual), and 2 GB GDDR5 memory running across a 256-bit wide interface. As we know, the GK104 will feature 1536 Stream Processors, 128 TMUs, and 32 ROPs. As with the AMD Radeon 7000 series cards, the GeForce GTX 680 will be based on a PCIe 3.0 bus interface with support for DX11.1, Quad Way SLI and display outputs of two DL-DVI, a HDMI and Display port 1.2. The card will utilize two 6-pin PCIe power connectors and has a TDP of 195W.
