NVIDIA's flagship single-GPU graphics card, the GeForce GTX 680, achieved performance leadership over AMD's Radeon HD 7970, and forced a price-cut, however, a section of the community feels that availability is an issue with it. According to NVIDIA, availability is attributed to sales, and not lack of volumes. At an annual investors' meeting with the company's top-brass, NVIDIA released a slide which depicts GeForce GTX 680 as having 60% higher sales than GeForce GTX 580, six weeks following their respective launches.

There is one cosmetic inaccuracy in the graph, though. GeForce GTX 680 and GTX 580 are labeled "GT". One inference that can be drawn out of the graph is that NVIDIA is seeing some success in putting the 28 nm silicon fabrication process to use, despite the GTX 680 being one of the first chips built on it. In comparison, the GTX 580 arrived when the 40 nm process achieved a higher level of maturity. There seems to be a genuinely high demand for the GTX 680.
