INTEL ATOM SERIES

 Atom Z series

Computer Module based on Intel Atom Z5xx with US15W System Controller Hub.

On March 2, 2008, Intel announced a new single-core processor (code-named Silverthorne) to be used in ultra-mobile PCs/Mobile Internet Devices (MIDs) which will supersede Intel A100. The processor is a 47 million transistor, 25 mm², sub-3 W IA processor which allows ~2500 chips to fit on a single 300 mm diameter wafer, allowing for extremely economical production.

An Atom Z500 processor's dual-thread performance is equivalent to its predecessor Intel A110, but should outperform it on applications that can leverage simultaneous multithreading and SSE3.They run from 0.8 to 2.0 GHz and have between 0.65 and 2.4 W TDP rating respectively that can dip down to 0.01 W when idle. It features a 2-issue simultaneous multithreading, 16 stage in-order pipeline with 32 KB instruction L1 and 24 KB data L1 caches, integer and floating point execution units, x86 front end, a 512 KB L2 cache and data transferred at 533 MHz on the front-side bus. The design is manufactured in 9M 45 nm high-k metal-gate CMOS and housed in a 441-ball µFCBGA package.

 Atom N series

The Intel Atom N270

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 core speed (both N270 & 230 are single core) with a 533 MHz FSB speed. An N280 with a 1.66 GHz clockspeed and a 667 MHz FSB has since appeared. Both the Atom N270 and Atom N280 are single core processors which support Intel Hyper-Threading Technology.

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 a 1.6 GHz clock speed and has an FSB running at 533 MHz. The processor has an 8 W TDP rating. Its dual core comprises two Diamondville dies next to each other on a single package (substrate). Atom 330 supports 64 bit instructions.

During 2009, Nvidia used the Atom 300 and their GeForce 9400M chipset on a mini-ITX form factor motherboard for their Ion platform.
