See this, that's a significant win on integer for A15, although Jaguar is a bit faster on FP when you normalize frequencies. So AMD would already make better servers if they replaced Jaguar in X2150 with A15.

And since you mentiond Silvermont, this is Tegra K1 vs Z3770. Enough said.

But I guess you're going to claim next that A57 is slower than Silvermont, am I right? :-)
