NVIDIA GEFORCE GTX 680 (Kepler) 2GB Reference Card Video Card Review - The Card and Specifications

As far as NVIDIA knew we couldn't get a GTX 680. We told them differently, so let's show you the latest GTX 680 from them, before the NDA goes off.

The Card

Looking at the cooler design there's nothing too out of the ordinary when it comes to the overall look of it. We've got that fairly standard setup with the fan on the far right that helps pull in cool air, drag it across the GPU and extract it straight out the back of the case. Noise levels and temperature are always going to be interesting on these new cards, so it will be interesting to see how it goes.

One of the biggest surprises from the new GTX 680 comes in form of the power setup. As you can see above we've got a dual 6-pin setup. When it comes to these high-end single GPU cards we expect an 8-pin + 6-pin setup. The fact that NVIDIA is able to get away with a dual 6-pin setup is surprising. It will be interesting to see the power draw on the new model, an area that NVIDIA has tended to sit a little higher in.

Moving across the top and closer to the front of the card you can see we've got a pair of SLI connectors. This will give us the ability to run up to four NVIDIA GTX 680s in a system that supports it.

Finally we finish up with the I/O side of things and it's nice to see that NVIDIA are throwing DisplayPort into the mix which is seen on the far left. Next to that we've got HDMI along with two DVI connectors - one Dual-Link and one Single Link.

 

 

Specifications

 

When it comes to specifications we can unfortunately only really tell you what we're seeing here in GPU-Z today. That's telling us that we're dealing 1536 CUDA cores and 32 ROPs. As for the core clock you can see that comes in at 1006MHz and the new "Boost" or "Dynamic OC" goes to 1059MHz which can be seen on the furthest most panel - hardly much of an improvement in clocks at all.

As for the memory side of things we've got the model that comes with 2GB of GDDR5 memory. That is on a 256-bit memory bus and carries a clock speed of 6008MHz QDR.
