First reports of imminent release of energy efficient Athlon II X3 400e and 405e processors surfaced in early 2009. There were rumors they would be released in June 2009 together with other Athlon II microprocessors. In June 2009, AMD introduced a mixture of Phenom II X2, X3 and X4 CPUs, and only one microprocessor from Athlon II family - dual-core ADX250OCK23GQ (model 250). In the course of the next three months AMD introduced standard power dual- and quad-core Athlon II CPUs. At long last, energy-efficient Athlons were announced in October 2009. Although these processors appeared in OEM systems, they were very difficult to find in US retail and online stores. Even now, three months after official release, very few stores in US have these processors in stock.
