And what do you think can tell the whole perf story? It has less pipelines, less execution resources, slower cache, only single channel memory and based on its size it has probably smaller ooo buffers, smaller uop reservation station and smaller register renaming files (relative to athlon64). You dont really expect that it will be faster then pentium (penryn/westhmere based) just because AMD said "90% of mainstream performance". Do you?
