Nvidia 'Kepler' GeForce GTX 680 Specifications Leaked

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.

As we saw at the Game Developers Conference, Epic showed the infamous Samaritan Demo running on a single Nvidia's Kepler GPU, which could be the aforementioned GTX 680. Now, we see a slide coming out of NGF community that shows the performance of the GTX 680 versus AMD's top two cards, the HD 7970 and HD 7950. The slide uses the HD 7970 as the baseline for performance comparison. Looking across the board, the GTX 680 outperforms the HD 7970 by roughly 20 percent in the seven games/benchmarks utilized. The one benchmark that stands out the most is the performance increase with Battlefield 3 (4xAA). The GTX 680 shows over a 40 percent performance increase, which could be related to use of Nvidia's FXAA technology.

Back in early March, we saw the first images of the GK104 card thanks to a leak coming from Chinese web-site Chiphell. Today, Chiphell has provided us with other leaked images and this time it is a near-final version of the graphics card. From these images, we see the cards Quad Way SLI support, along with its unique stacked power connector setup.

There is no official pricing for the card but early reports has it falling around $500 dollars. Stay tuned for more coming soon!

  • The average performance advantage is only around 10%, but Nvidia used the old trick of not setting the baseline to zero... That being said, a 10% advantage is still nice, although a 7970 OC to 1GHz can probably match that, and most can actually be OC to 1.1GHz without any trouble. So for me it looks like a draw, which is not that good for Nvidia as there 4 months behind...

    Can't wait till it hits the shelves! We'll see what the retail price ends up being, and what 3rd party reviewers bench it out at. Only then will we know how the top cards compare.

    The ball in in your court AMD. Better get the price guns ready. ;)

    Nice trick with starting the graphs at 0.8.

    its a damn good card but the chart is a little bit misleading :) 0.4 is way longer than 1

    Regardless of where the graph starts, if the specs prove to be true, they are quite impressive.

    lmao. Late but great?

    Wonder how true this is, if it is then...AMD won't be very happy, will it? I mean this is like GTX 590 performance!

    And wow at the power...can Nvidia be efficient? AND compete on price?

    Man, scary times for Team Red, if this is true...

    The graph data is normalized around the performance of the 7970. There is no "trickery" here. According to the graph the 680 will be about 42% faster then a 7970 in Battlefield 3.

    like it or not this is very impressive...... nVidia's code is lot better when it comes to raw performance.....it's kind of like how Intel's cpu code is more superior when compared with AMD's code....you can have powerful hardware but if the code sucks the hardware will also suck
