Yes Geekbench is stupid, but I have to correct you when you say ARM flushes to zero. It does not.
Also, Intel is not immune to benchmark-eting. Check out the latest slide on the 64-bit 'advantage' where they show crafty and eon performing much better on 64-bit vs. 32-bit. This is pretty extreme cherry picking as they don't show the benchmark that slow down due to pointer expansion.
