A major breakthrough was announced in the computing world yesterday as a new type of processor was released by the computing firm Smart Designs, Inc. According to Smart Designs, the new processor uses special technology to massively decrease the size of its components, allowing the power of as many as 100 top-of-the-line processors to fit into the space of one. While details of the new technology have not been released yet, a demonstration of a computer using the new processor was made yesterday at Compucon, an annual New York computer convention.
Founded by entrepreneur Jamie Smart in 1987, Smart Designs originally manufactured a range of computer products before focusing on their processor designs in the late 90s. It was announced that Smart, now CEO, will give a press conference later this week to describe plans for the production and sale of the new computer component, as well as more details of the advanced technology it relies on. However, analysts are already forecasting a price tag of over $2,500 per unit based on the demonstration at Compucon. Shares of Smart Designs, Inc. (NYSE: SMDG) have risen by 33 percent since the news was released.
