AMD has still not set an exact launch schedule for Wichita, its 28nm second-generation entry-level APU. Given the uncertainties, it seems likely that the chip may be released later than expected.

Officially, the code-named Wichita accelerated processing unit (APU) is planned to be released in 2012. However, a source with knowledge of AMD's plans said that the company still has not set any exact schedule for the roll-out of its second-generation entry-level APU-based platform. In fact, AMD intends to sell its Brazos chips till Q4 2012 at least, according to the person, who decided to remain anonymous. However, it should be noted that the existing plans are not final.

AMD code-named Wichita accelerated processing unit is a pretty revolutionary design that will be the industry's first quad-core x86-based system-on-chip with built-in graphics and I/O capabilities. Wichita will integrate up to four Bobcat-class x86 cores with Turbo Core 3.0 dynamic acceleration technology, DirectX 11 graphics core, DDR3 memory controller as well as Yuba FCH [Fusion controller hub] that will support Serial ATA, PCI Express, USB and other I/O protocols. AMD Wichita, which will utilize FT2 BGA packaging, will be the heart of Deccan platform for netbooks, low-cost ultra-thin notebooks and nettops.
