4th Generation Intel Atom processor -BayTrail

     Intel has launched the 4th generation Intel Atom processor, code-name BayTrail. This latest Atom processor is a Multi/Quad-core system-on-chip (SoC) that integrates the next generation Intel processor core, graphics, memory, and I/O interfaces into one solution. It is also Intel's first SoC which is based on the 22 nm processor technology. This multi/quad-core Atom processor provides outstanding computing power and is more power efficient compared to its predecessors. Besides latest IA core technology, it also provides extensive platform features, such as graphics, connectivity, security, and sensors, which enable developers to create software with unlimited user experiences.

BayTrail-I Introduction

     Baytrial-I platform combines a CPU based on Intel’s new Silvermont architecture with a GPU that is architecturally similar to (but less powerful than) the HD 4000 graphics engine integrated in the 3rd generation intel Core processors launched in early 2012,These core components are combined with dedicated I/O blocks and media encoding and decoding to make one system-on-a-chip, which is then manufactured on the 22nm process (and the 3D tri-gate transistors) currently being used for both the 3rd and 4th generation Intel Core processors.
     Since Silvermont is the first major overhaul of the Atom CPU architecture since it was introduce in 2008, the main performance is improvement will come from the CPU’s new out-of-order (OoO) execution engine, which allows the CPU to process different instructions as soon as resources to execute them are available. On the graphics side, Baytrail-I ‘s GPU uses the same Intel execution units (EUs) as the 3rd generation intel Core processors ’s HD 4000 which gives them support for most of the same APIs and features: DirectX 11, OpenGL 4.0 (and OpenGL ES 3.0 on mobile, Provider the drivers support it), and OpenCL1.2 support are all present on API side, and dual-display support for panels up to 2560x1440 (or 1080p over HDMI) as well as via Intel’s Wireless Display feature will please multi-monitor fans.
