Intel quad-core SoC processors detailed in leaked documents

Leaked documents suggest that Intel's new Atom System-on-a-Chip processors will come in one, two, and four core variants, have clocks speeds ranging from 1.2GHz to 2.4GHz, and feature a 7th-generation GPU that is up to seven times faster than current Atom offerings.

Details of Intel's 22nm microarchitecture Atom processors have been revealed in a leaked document found on Baidu by German tech site ComputerBase.

The Atom SoC (System-on-a-Chip) processors, codenamed ValleyView, which are based on the Silvermont architecture, are part of Intel's Bay Trail platform and will be offered in four variants. The ValleyView-I will be aimed at industrial and automotive applications, ValleyView-D at desktop systems, ValleyView-T for mobile devices, and ValleyView-M for, believe it or not, netbooks.


The processors will be available in one, two, and four-core variants, with each core having 512MB of L2 cache, and in clocks speeds ranging from 1.2GHz to 2.4GHz.

While cores and clock speeds are important, where the ValleyView parts will really shine is in the graphics department. The new processors feature Intel's 7th generation graphics engine and will offer a performance increase of between four and seven times compared to the GPUs packed into the E600-series Atom parts.

The video decode rates of these GPUs will be fast enough to handle 1080p video at 60 frames per second with only a 5 percent load on the CPU. These processors will also be able to encode 1080p video, but at a more modest 30 frames per second.


The ValleyView SoCs will support up to 8GB of DDR3 RAM and will support Intel HD audio, PCi-E 2.0, SATA 2.0 and, more importantly, USB 2.0 and 3.0.

According to the leaked document, the ValleyView parts will become available during the fourth quarter of 2013.
