Based on data available so far, we were expecting the upcoming AMD Nolan and Amur APUs to be the first 20nm processors from AMD. However, a new report published today by WCCFTech claims that the AMD Nolan APU will be built on a 28nm process and only the Amur APU will be a 20nm chip.
The website claims to have received word from an industry source that the Nolan APU will be a subtle upgrade to the Beema/Mullins platform and will be FP4 BGA packaged just like the Carrizo chip. As for Amur, the source claims that it is likely that Amur will be manufactured on a 20nm node but cannot confirm it as there are chances that the Amur will also be built on a 28nm process and only the successor to Amur will switch to 20nm.
Both Nolan and Amur are expected to be released by AMD by the second of this year. They are expected to be quad-core processors and include integrated Radeon graphics. While no concrete information is available so far, Amur is believed to bring support for Android and Linux while Nolan will support Windows and Android.
