Clock for clock, pipe for pipe (15 stages in A57, 14-19 in Haswell) x86 still wins because of per-instruction operand volume.
Though i wonder how well this chip would perform at 50w. Double the watts, maybe another 1.5ghz, might be viable for a cheap htpc.
As a general rule, power varies with the cube of frequency. 50W will only get about 2.5 GHz.
