AMD Ontario APU pictured,die size ~77mm^2

[informal]

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?

I don't expect anything,I just quoted the hw-info article.And AMD stated the 90% of mainstream performance while mainstream in their pricelist is Regor(and Regor pretty much matches Penryn 3M).You can draw your own conclusions.

PS The Bobcat core is also new from the ground up design(not based on K8/10h),has more OoO capabilities than 10h and shares some functionality that is in BD.
