Intel Atom Cedarview Mobile CPUs Use Less than 2W of Power

While we are still waiting for the official debut of the first mobile Atom processors based on the Cedarview architecture, a German publication has managed to uncover a series of new details about these chips, including the power consumption of the CPUs.

These new Intel chips will go by the name of Atom N2600 and Atom N2800 and just like their desktop counterparts feature two processing cores with a total of 1MB of Level 2 cache memory.

Their operating frequencies however, have been reduced in order to make them better suited for the mobile environment, and the Intel Atom N2800 works at 1.86GHz, while the less powerful N2600 is clocked at 1.6GHz.

Outside of the increased processing speed, the N2800 also sports an integrated 1066MHz memory controller as well as a 640MHz on-die GMA 3650 GPU that is based on a PowerVR SGX545 core.

This adds a series of multimedia oriented capabilities to the Cedar Trail platform including support for Blu-ray 2.0 video playback.

The same graphics PowerVR graphics unit is also used for the N2600, but, this time, the GPU operating frequency has been lowered to 400MHz.

Compared to its older brother, the N2600 also comes with a slower memory controller that supports DDR3 DIMMs clocked as high as 800MHz.

The most surprising feature of these new Atom processors however is their power consumption, as Intel has managed to reach some extremely low values.

According to the information provided by the German website Heise, the N2800 requires only 1.81 Watts of power in order to function, while its smaller brother drops this figure to an impressive 1.09W.

Both the N2600 and N2800 are designed to be paired together with the Intel NM10 chipset, which was also used by the Santa Clara chip giant for the previous Pine Trail Atom platform.
