In other more generic benchmarks you see Cortex-A9 CPUs taking on the Atom just fine. The Cortex-A15 does a lot better. That benchmark you are showing is for a particular case where x86 has an advantage. Something that will not be used in emulating.
Look at the benchmarks that use pure math rather than video encoding or specialised tasks that x86 has instructions for. Meanwhile the compiler probably isn't optimising the heck out of A15 yet since it's so new. You'll see Cortex-A15 only a factor of 2 or 3 out of the 330m (which is a high powered 35W i3). The low-specced i3 uses only 18W.

As I said earlier, you also have to account for the benefits of ARM emulating PPC over x86 emulating PPC.
While I don't expect the four cores to help, the high clock (when in dual-core mode) will definitely help.
