Intel in its latest circular to netbook manufacturers said that it will stop taking orders for the Atom Z500 "Silverthrone" series processors very soon. Z500 series is Intel's first line of Atom processors since the introduction of the Atom brand. The series consists of single-core chips with clock-speeds ranging between 800 MHz and 2.00 GHz, with almost 11 models. The series is succeeded by the Atom N200 and N400 "Diamondville" and "Pineview" series.

Intel seems to have stopped manufacturing these chips upon the introduction of the Atom N series, and continued taking orders for the inventories to digest. The company will, however fulfill existing orders from manufacturers such as Acer, ASUS, and MSI, note industry sources. Intel's Atom Z series targets netbooks and mobile internet devices (MIDs).
