Tech: Nvidia GTX 680 Kicks Off New Graphics Range

Graphics processor company Nvidia has launched a new graphics card overnight that will bring powerful capabilities to high performance video games.

The Nvidia Kepler GTX 680 goes on sale internationally at a retail price of around AU$659 and is able to run last year’s Unreal Engine 3 tech demo “Samaritan” by itself and powered by a regular power supply, a significant boost from last year’s GTX 580s which required three cards hooked up to a blistering 1200 W power supply.

This is one of the main focuses on the GTX 680; efficient performance. It’s 1536 cores end up getting twice as much power per Watt, making it cooler and quieter to run than previous models. The card also supports GPU Boost which allows the card to dynamically change it’s clock speed depending on the needs of the application.

Also announced was the Adaptive V-sync feature that checks the frame rate every 100ms – if your monitor can’t support the high frame rate of your content, V-Sync will turn on to prevent “tearing” on the screen. Likewise, when the frame rate of your application falls below the monitor specification, it will switch off to prevent stuttering.

The card also comes with a new anti-aliasing technology; TXAA which is leagues ahead of industry standard MSAA. Basically, TXAA gives the advantage and power of 8X MSAA but at the cost of 2X MSAA, meaning the card can perform much better anti-aliasing with less processing power.

Overall, the Kepler GTX 680 is looking pretty sweet. As if you needed convincing, Nvidia released a video overnight showing off some of the things the card is capable of, which includes realistic destruction and fantastic fur rendering techniques. Tomorrow’s games are going to look sweet.
