Although Intel just officially launched its Atom processor lineup yesterday at Computex, the chip is already in short supply and that has some Taiwanese manufacturers concerned. The low-cost ultra-mobile PC bandwagon is getting crowded these days as more companies scramble to get a seat before being left behind. Asus just announced two new Eee UMPCs along with the Eee box mini-desktop PC, all of which will use the Atom processor. Encouraged by the Eee's phenomenal success, other manufacturers such as MSI (Wind) and Acer (Aspire One) are also launching Atom-based PCs. With Asus forecasting sales of 5 million units this year and Acer predicting sales of up to 7 million units, Intel has promised increased production. The Atom is manufactured on 300mm wafers using a 45nm process. Due to its diminutive size, Intel can squeeze 2,500 processors onto a single wafer. Hardware makers are hoping Intel can solve the supply shortage in time for the back-to-school and year-end holiday sales seasons.
