AMD will phase out its budget Duron processors by the end of the year as part of the release of the upcoming Hammer chips.
CEO Jerry Sanders and President Hector Ruiz, who will become AMD's CEO next Thursday, laid out the company's manufacturing plans Wednesday for the future, and they don't include Duron.

Instead, AMD will position Clawhammer, a chip that is expected to make its debut by the end of the year, as its premier desktop and notebook chip. Meanwhile, Athlon, the company's current top-end chip, will become its processor for cheap desktops and notebooks. Source: ZDNet
