In 2012, Intel expanded the Atom processor family with a new system on chip (SoC) platform designed for smartphones and tablets.[1] It is a continuation of the partnership announced by Intel and Google on 13 September 2011, to provide support for the Android operating system on Intel x86 processors.[2]
Atom competes with existing SoCs developed for the smartphone and tablet market from companies like Texas instruments, Nvidia, Qualcomm and Samsung.[3] Unlike these companies, which use ARM-based CPUs designed from the beginning to consume very low power, Intel has adapted the x86 based Atom line CPU developed for low power usage in netbooks, to even lower power usage.
In April 2012, several manufacturers have released Intel Atom-based phones; as a result of testing industry reviewers came to conclusion that Atom SoC-based smartphones can compete both power-wise and performance-wise with currently dominating ARM-based smartphones.[citation needed]

Testing of Atom phones [edit]
In April 2012, Lava Xolo X900 phone has been released as a first Intel Medfield phone.[46] Industry reviews have claimed that Lava Xolo X900 proves that the statement "Intel can't make smartphones" is wrong, and that "Intel is going to power smartphones, and it’s going to be competitive in that space."[47] It has also been claimed that power-wise Intel Medfield-based smartphones have been shown to be competitive with ARM-based ones: "The x86 power myth is finally busted. [...] If you've been expecting the first x86 smartphone to end up at the bottom of every battery life chart, you'll be sorely disappointed."[46] Z2760 scored a 679 in the Passmark benchmark test.[48]
Operating system support on Cloverview [edit]
While Penwell SoC supports, in addition to Microsoft Windows, both Linux and Android operating systems, Intel has announced that it won't provide support for Linux on Cloverview family of Atom systems-on-a-chip.[49][50] This announcement has caused strong negative reaction from open source proponents.[51] A few days later Intel issued a statement saying that it has “plans for another version of this platform directed at Linux/Android"[51][52]
New power states on Cloverview [edit]
Z2760 Cloverview has introduced two new power states: S0i1 and S0i3.[53] The S0i1 state is intended to be used when the display is on but the user does not actively interact with the device; it consumes power in mW range, and can be entered/left in microseconds. The S0i3 state is intended to be used when the device display is off; it consumes power in microWatt range, and can be entered/left in milliseconds. As a result, Intel claims longer standby battery life (up to three weeks for a typical tablet).[53]
Roadmap [edit]
In May 2011, Intel has announced an accelerated roadmap for Atom SoC, with 22 nm Silvermont core scheduled in 2013, and 14 nm Airmont core scheduled in 2014.[54]
It has been reported that Silvermont-based Atom SoCs will be named Valleyview, will be available in single-, dual- and quad-core versions, and will include Intel's 7th generation GPU, allowing for 4-7× improvement over existing Atom GPUs.[55][56]
