Atom Processor,Intels Smallest Chip

Digg it !!!

Intel atom is the new processor from Intel specially manufactured for mobile internet devices(MIDs). Previously codenamed Silverthorne and Diamondville, it is now given the new name atom. Major fields of application include Smartphones and ultramobile PCs whichare of relatively smaller size. The mobile technology which incorporates this processor is called Centrino Atom. Actually this is the first X86, a bit old I have to say, based processor after Intel Pentium.

Atom processors are the Intel's smallest processors and have modern functions like EM64T, SSSE3, etc.It is built with world's smallest transistors.Newly designed the Intel® Atom™ processor is based entirely on new hafnium-based 45nm microarchitecture.

Representing Intel's smallest and lowest power processor yet¹, the Intel® Atom™ processor enables a new generation of powerful and energy-efficient Mobile Internet Devices (MIDs) and a new category of simple devices for the internet called netbooks and nettops that will be available at affordable prices.

Delivering new design possibilities due to its remarkably small size and performance-per-watt advantages, the Intel Atom processor provides:

* Performance for a great internet experience in a range of sub 1 watt to 4 watt thermal power envelope based on industry leading benchmarks (EEMBC) and web page rendering performance
* Greater energy efficiency for mobile devices enabled by incredibly low average power and idle power, scaling performance from 800MHz to 1.86GHz
* Power-optimized front side bus of up to 533MHz for faster data transfer on demanding mobile applicationsĪ”
* Scalable performance and increased power efficiency with multi-threading support²
* Improved performance on multimedia and gaming applications with support for Streaming SIMD Extensions 3 (SSE3)
* Improved power management with new Deep Power Down (C6) enabled on the Intel® Atom™ processor Z5xx series for MIDs, and extended C4 states enabled on Intel® Atom™ processor N270 for netbooks, in addition to non-grid clock distribution, clock gating, CMOS bus mode, and other power saving architectural features
* Low TDP enabled by improved power management technologies delivering high performance to run the real Internet and a broad range of software applications³.

The chipmaker on last April introduced five new Atom processors and Intel Centrino Atom processor technology for MIDs and embedded computing solutions. The Z500, Z510, Z520, Z530, and Z540 chips draw between 0.65 and 2.4 watts (compared to notebook chips that typically draw between 20 with 35 watts). Speeds range from 800MHz to 1.86GHz, with list prices ranging from $45 to $160.

All Atom chips come with 512K of L2 cache memory and have die sizes of 7.8mm x 3.1mm. Atom technology includes a single-chip with integrated graphics called the Intel System Controller Hub, Intel said Wednesday. Device manufacturers are planning to ship MIDs beginning this summer, Intel said. Atom will find its way into fit-in-your-pocket MIDs from Gigabyte, Toshiba, LG Electronics, Lenovo, and BenQ, among others. Netbooks (inexpensive, Internet-centric ultra-small notebook PCs) such as Asus's popular Intel-based Eee PC, MSI's Wind PC, and Clevo will also use the chip.Atom will also be employed in low-cost desktops called Nettops.
Though some computer makers will opt for Windows, many MIDs, Netbooks, and even Nettops will use the Linux OS.
