Intel Atom is the brand name for a line of x86 and x86-64 CPUs (or microprocessors) from Intel, designed in 45 nm CMOS and used mainly in Notebooks. Silverthorne is called the Atom Z series and Diamondville is called the Atom N series. As of June 2009, the most used chips in the Netbook retail market are Z520, Z530, and N270

Prior to the Silverthorne announcement, outside sources had speculated that Atom would compete with AMD's Geode system-on-a-chip processors, used by the One Laptop per Child project, and other cost- and power-sensitive applications for x86 processors. However, Intel revealed on October 15, 2007 that it was developing another new mobile processor, codenamed Diamondville, for OLPC-type devices.

"Atom" was the name under which Silverthorne would be sold, while the supporting chipset formerly code-named Menlow was called Centrino Atom. Intel's initial Atom press release only briefly discussed "Diamondville" and implied that it too would be named "Atom", strengthening speculation that Diamondville is simply a lower-cost, higher-yielding version of Silverthorne with slightly higher TDPs at slightly lower clock speeds.

At Spring Intel Developer Forum (IDF) 2008 in Shanghai, Intel officially announced that Silverthorne and Diamondville are based on the same microarchitecture. Silverthorne will be called the Atom Z series and Diamondville will be called the Atom N series. The more expensive lower-power Silverthorne parts will be used in Intel Mobile Internet Devices (MIDs) whereas Diamondville will be used in low-cost desktop and notebooks. Several Mini-ITX motherboard samples have also been revealed.Intel and Lenovo also jointly announced an Atom powered MID called the IdeaPad U8. The IdeaPad U8 weighs 280 g and has a 4.8 in (12 cm) touchscreen providing better portability than a netbook PC and easier Internet viewing than a mobile phone or PDA.
Atom N series
On March 2, 2008, Intel announced a low-cost mobile processor (code-named Diamondville) to be used in the Classmate PC Netbook. It is used in Intel's low-cost Mini-ITX motherboards (code-named "Little Falls") and in a number of netbooks.It will supersede Conroe L as the N270 (2.5 W TDP) for netbooks and as 230 (4 W TDP) for nettops, each running at 1.6 GHz per core with a 533 MHz FSB speed. An N280 with a 1.66 GHz clockspeed and a 667 MHz FSB has since appeared.
Atom 300 series
On September 22, 2008, Intel announced a new dual-core processor (unofficially code-named Dual Diamondville) branded Atom 330 of the Atom 300 series to be used in desktop computers. It runs at 1.6 GHz and has a 8 W TDP rating. Its dual core comprises two Diamondville dies next to each other on a single package (substrate).
The intel D945GCLF2 is a mini-ITX board that contains the Atom 330.
The Zotac IONITX-A-U is a board that pairs the Atom 330 with NVIDIA's GeForce 9400M chipset. The intel Atom CPU, when paired with NVIDIA's GeForce 9300M or 9400M chipset, is often called the NVIDIA ION platformRead More >>>>>>>>>>>>>>
