The Calexia Highbank Nodes are quad core. Relative to the OMAP4 tested, Exynos 5 has a 1.4x higher clock but 1.9x better 7-zip performance and 2.3x better x264 performance. For reference, A15 has double the vector execution resources as A9 in addition to adding out of order execution. Integer execution resources remain the same (two symmetric pipelines) but gains triple issue, wider out of order, and the potential of two load/store per cycle.
So simple integer heavy workloads aren't expected to be incredibly faster from A9, just the ~40% ARM quotes and these tests back up.
Atom D5xx has two hyperthreaded cores, and hyperthreading does help a lot for x264 at least. IIRC when I tested on a single-core Atom, the hyperthreading gave x264 a 1.6x boost.
