I get 723.7 for A9 and 717.8 for CT+.
I used sum because Geekbench seems to use arithmetic means. Anyway my point wasn't to provide a score, just to show that even on integer loads ARM is faster at Geekbench than CT+.

Heh it seems the poor Geekbench will never be able to correctly identify CPUs :-)
