NVIDIA's next enthusiast-grade graphics processor, the GeForce GTX 580, based on the new GF110 silicon, is poised for at least a paper-launch by end of November, or early December, 2010. Sources in the video card industry told DigiTimes that the GTX 580 is expected to be 20% faster than the existing GeForce GTX 480. The new GPU is built on the existing 40 nm process, NVIDIA's 28 nm GPUs based on the Kepler architecture are expected to take shape only towards the end of 2011. Later this week, AMD is launching the Radeon HD 6800 series performance graphics cards, and will market-launch its next high-end GPU, codenamed "Cayman" in November.
