NVIDIA GeForce GTX 680 (Kepler GK104 GPU) Officially Launched

NVIDIA GeForce GTX 680



GeForce GTX 680 Overview

Here we are, NVIDIA has officialy launched the GeForce GTX 680 based on the Kepler GK104 GPU. This card packs a bunch of new features (and some of them can be tweaked with some line of code!) such as GPU Boost (dynamic clocking depending on GPU load), adaptive VSYNC, bindless textures, new power management functions (Power Target), TXAA (temporal anti-aliasing), NVENC (encoding engine) and optimized power consumption. The architecture has been changed (no double speed anymore for shader processors, this is the new SMX unit) and priced at USD $499, this card targets AMD Radeon HD 7900 series.
