Intel Atom Logo — Intel Atom are microprocessors from Intel that are designed for particularly cost-effective and energy-saving systems. They are based on the Intel Atom microarchitecture and are including in sub-notebooks , mobile Internet devices and the like are used, but they are also more common in low server solutions are used. You are using an x86 instruction set , from the second generation (Diamondville called) is an x64 instruction set has been completed.

Some of the Atom processors have a very effective power-saving mechanisms by which the very low power consumption can be reduced further at idle. In addition to the now standard on virtually all processors SpeedStep there is a further saving mode in complete inactivity. This differs from the battery life on an Atom based netbooks for example, between reading and writing of texts. For other processors, this amount of activity shows no effect.

Mainly for financial reasons was used for the nettop Atom (Atom 230 and 330) of the Intel 945GC chipset provided. On the use of this chipset, there are a lot of criticism because its energy consumption is quite high, it requires significantly more energy than the processor itself A typical nuclear-230 system does with this chipset so in idle about 25 W at full load about 35 . W of power at [14] Furthermore, in particular the performance of the graphics used in this unit is very limited, so is the representation of Blu-ray films or the use of modern 3D games simply impossible.

Nvidia offers but for some time as a counterpart the ION platform to, in their 9400 chipset integrated GeForce graphics appropriate unit including HD acceleration. The Netbook Atom N270 used in conjunction with the Mobile Intel 945GSE chipset, which reduces power consumption compared to the other variants by about 10 W (in both cases). The N280 is used in conjunction with the Mobile Intel chipset 945GSE or GN40. The power requirement is about 8 watts with the 945GSE chipset and 16 watts with the GN40 chipset. Alternatively, partially used specifically for the Silverthorne Atom chipset developed economically named “Poulsbo” or “US15W”. To this belongs the GMA500 graphics core of the PowerVR Technologies is. The GMA500 is not technically related to the standard Intel GMA and also requires its own, only for Windows XP drivers available. He may be an acceleration of HD video capable, but the 3D performance is still lower than the GMA950.

All Atom processors are in the 441 — or 437-ball μFCBGA offered by the board and soldered directly to the board manufacturers. A subsequent processor exchange is excluded. Pine Trail, there is a completely new chipset called “Tiger Point NM10″, which is technically only a Southbridge is. The graphics unit and the memory controller is now part of the processor.
