Nvidia Geforce GTX 680



Today was launch day for the Nvidia Kelper line, the first model in the GeForce Kepler GPU family, the GeForce GTX 680. Based on the new "Kepler" architecture, and a high-performance chip derived from it, GK104, and built on the 28 nm fab process at TSMC, the GeForce GTX 680 is NVIDIA's fresh bid for single-GPU performance supremacy. The new chip packs a staggering 1536 CUDA cores (three-fold increase over GTX 580), 2 GB of GDDR5 memory over a 256-bit wide memory interface, and staggering clock speeds of 1006 MHz to 1056 MHz, and 1502 MHz, with a memory interface bandwidth of 192 GB/s. Nvidia didn't stop there they introduced a clever new technology called GPU Boost, which makes the GPU self-aware of parameters such as load, voltages, temperatures, and auto-tunes clock speeds, to deliver the best performance per Watt ratio. NVIDIA also introduced Adaptive V-Sync, which smooths transition between lower than refresh-rate frame-rates, and V-sync rate, attempting to eliminate lag, and naturally prevent page-tearing. NVIDIA also introduced the new TXAA anti-aliasing algorithm, which is a performance-efficient image quality enhancement. To top it all off, the chip has a TDP of just 195W. Available today, though leading retailers in mature markets, the NVIDIA GeForce GTX 680 is priced at US $499


Here is an unboxing video to tell you about what new things are in this card
