The new AMD processors , Bulldozer, sales is expected on 19 September. AMD has made some changes to their plans for high-end solutions. It was assumed that as change to Bulldozer CPUs will come Komodo with eight or ten cores. For some reason the company removed these CPU, while simultaneously stopping the development of Corona platform. Free places were taken by the processors and platform Vishera Volan (or Scrorpius Refresh).
About Vishera we do not know much. These chips will be the development of AMD FX Zambezi line and will be released next year. They will have eight cores, built on Piledriver architecture (Bulldozer new generation), dual-channel memory controller DDR3, and will be compatible with AM3 + socket and Scorpius platform, which is known by the chipset AMD 990FX.
If the information is correct, then it becomes clear that Vishera, in contrast to Komodo, will be less progressive. Most likely, AMD will not release a platform for high-end with support for PCI Express 3.0 in 2012 (Komodo should receive a built-in lines PCI Express 3.0). As always in such cases, AMD refuses to comment.
