AMD would be laptop and ultraportable platform codenamed Deccan have been deleted or at least for an indefinite period of time have been suspended. The company would have problems with the design or production of the chips.
The Deccan platform, which consists of motherboards with apu’s with the code names Krishna and Wichita, had in the course of 2012 appear on the market. The apu’s would, by TSMC are produced and on 28nm to be baked, but according Xbit labs, the platform is not yet on the roadmap of AMD included. It would not be known, or the delay or the deletion of the apus is due to design problems or to TSMC that the chips would not be able to produce.
The Krishna apu’s had to be fuel-efficient successors of the Ontario apus, which have a tdp of up to 9W. The apus would be equipped with one or two Bobcat cores of the second generation, or Enhanced Bobcat cores, combined with a gpu from the Northern Islands series. The more powerful Wichita-series would be equipped with two to four Enhanced Bobcat cores, Northern Islands gpu and a tdp to 20W.
With the collapse of the Deccan platform would AMD choose his current Ontario and Zacate-apu’s, which is part of the Brazos platform, something to improve. This would be the Brazos 2.0 platform is expected to generate, with slightly improved performance compared to that of the current Brazos platform. So would the Bobcat cores can still be used, but would be a more modern gpu in the apu can be integrated. Also, the chipset, the A68 Fusion controller hub, ” as an additional include usb 3.0 connectivity. Adjusting Brazos hardware for the Brazos 2.0 generation would be relatively simple.
One of the new Brazos 2.0-apu’s would be the E1-1200. This will have two Bobcat cores with a clock speed of 1.4 GHz, 1MB cache, Radeon HD 7310 gpu with 80 streamprocessors with a clock speed of 500MHz, and a tdp of 18W. The E2-1800 would be two cores at 1.7 GHz clocks, a faster HD 7340 gpu with 80 streamprocessors on 680 or 523MHz, and also a tdp of 18W. The new Brazos 2.0 chips are still on (40 nm) is produced and will appear, probably around april.
