you've been wondering about AMD's 2012 Deccan platform we bear some good news as the guys from Donanimhaber.com managed to snatch some fresh slides dealing with Wichita and Krishna chips. With up to four Bobcat cores, lower TDPs, better DirectX 11 graphics part, and Yuba FCH for some SATA and USB 3.0 fun it is quite clear that these will bring quite an improvement over currently available Zacate and Ontario chips.
As noted, both Wichita and Krishna will be made on the new 28nm manufacturing process and currently AMD is promising up to 20 percent higher processing power, over 25 percent higher graphics performance and up to 30 percent higher compute performance. Both Wichita and Krishna are a part of Deccan platform and will use a new FT2 socket. Of course we are talking about SoC desing and 2012 Deccan platform will feature up to four Bobcat cores at a lower TDP.
Spec wise, the Deccan platform will feature up to 2MB of L2 cache, new APM Bi-Directional Turbo Core feature, support for DDR3-1600 memory (including ultra low voltage DDR3 memory), AMD's UVD3 engine with Secure Asset Management Unit (SAMU), enhanced multimedia support and Yuba FCH with support for USB 3.0 and most probably SATA 6Gbps.
According to the latest roadmaps and rumours, AMD plans to start the production of these 28nm Witchita and Krishna chips sometimes at the end of Q2 2012.
