Intel Atom processor feature highlights


First-ever 22-nm Intel Atom processor

The new first-ever, 22-nm Intel Atom processor is a quad-core system on chip (SOC) with 4 cores/4 threads. With the CPU, graphics, and memory in one package, this modular design provides the flexibility to package a high-performance processor and graphics solution for multiple form factors.

Enhanced battery life

The new processor offers active battery life of more than 10 hours and standby performance of approximately 30 days3.

Graphics and Media Performance

The latest Intel Atom processor includes a 7th generation Intel® GPU with burst technology to provide a stunning graphics and media experience. The new processor supports high resolution displays up to 2560X1600 @ 60HZ and supports Intel® Wireless (Intel® WiDi) technology through Miracast. Seamless video playback is supported by a high performance and low power hardware acceleration of media encode and decode. The table below compares the two processors’ graphics features.

Intel Burst Technology 2.0

Automatically allows processor cores to run faster than the base operating frequency if they’re operating below power, current, and temperature specification limits.

Graphics Feature Comparison


Advanced Imaging and video

The new Intel Atom processor comes with an integrated image signal processor and supports excellent camera quality. It supports video capture at 1080p with full HD playback. Superior multi axis Document Image Solution (DIS) and image alignment extend High Dynamic Range (HDR) to moving devices hence removing the moving blur. Ghost removal is also extended from HDR to moving scenes.

Security Features

With people carrying their devices with them almost everywhere they go, they are more likely to lose their tablet or laptop. And even if they don’t lose them, devices are susceptible to the growing number of viruses and malware threats. Intel® Identity Protection Technology (Intel® IPT)4 can help businesses keep their critical information secure and protect against malware. Intel® IPT helps prevent unauthorized access to personal and business accounts by using hardware-based authentication.

New business-class tablets built with the Intel Atom processor Z3700 Series are specifically designed for the needs of business and the enterprise. Hardware-enhanced Intel® security technologies and support for software from McAfee offer robust security capabilities.

Intel® Wireless Display benefits on Intel Atom processor

Intel® WiDi enables content-protected HD streaming and interactive usages between tablets and TVs. It supports full 1080p video and low latency gaming, and is Miracast compliant Intel® WiDi can be used to link health indicators as well. A few of the capabilities of Miracast-enabled apps are:

  • Share & Enjoy: use a big screen HDTV to enjoy and share media with family and friends
  • Wireless: quickly and securely connect with standard Wi-Fi to a TV without cables
  • Easy Set-up: simple user interface makes it easy to connect; no additional remote controls
  • Portable: adapter is small and light, so solution can move with you

Resources for Developers


Below are links to some resources for programming on Windows 8 that can help you take advantage of the new Intel Atom processor features.
