Might AMD skip trying to catch up with Intel's 45nm process and go straight to 22nm? According to some recent reports, one of the manufacturing companies serving AMD, Foundry Co, is putting together a manufacturing plant that can produce 22nm wafers. The plant itself is expected to become operational in a little over three years - right around the time Intel is expected to have a 22nm process ready.
Given AMD's huge move the past week and their obvious struggles in CPU manufacturing, particularly in the desktop market, their CPU business might take a breather while they wait for technologies smaller than 45nm.
