At half the performance, which is an irrelevant comparison here.
Generally AArch64 should be +10% perf.
Where does that +10% perf figure come from? How much of that comes from extending to 64-bits?
Perhaps ISA can have a notable impact if you have enough cruft affecting common instrs. Predication may be a culprit. But A32 vs A64 is not something I looked into
