Another year passes along; another high-end card enters the market, another fight between AMD and Nvidia for the graphical crown. While the previous generation was completely owned by Nvidia when it came to the ‘fastest’ graphics card with the GTX 580, the HD 6990 vs. GTX 590 debacle notwithstanding, this time around things have gotten quite exciting.
Last year AMD released their flagship HD 7970 graphics card which easily bested NVidia’s GTX 580, but this was not an easy victory. And a short lived one at that, as you’ll find out soon enough. Today I’ll be looking at the Nvidia GTX 680 graphics card, a GPU many PC enthusiasts have been looking forward to since early this year.
Like the AMD HD 7000 series, the first thing to note about NVidia’s new Kepler architecture is that the GTX 680 runs on a 28nm core. It has a relatively low TDP of 195W and requires just two 6-pin connectors to power itself; a minimum PSU of 550W is recommended.
Measuring a little lesser than the GTX 580, the GTX 680 comes in at 10-inches. The rest of the specs for the GTX 680 are listed below.
Just on paper the AMD HD 7970 seems superior, tech wise, than the GTX 680. The memory bandwidth, number of transistors and shader count on the HD 7970 are more than the GTX 680, but NVidia’s champion does have higher clock speeds. We’ll soon find out whether the Kepler architecture is better than Tahiti or not.
