Galaxy Note 3 boosting benchmarks?

Ill post the article down below but the way i understand this is that when its running a benchmark, it turns all cores on and sets it at max performance.  I don't understand how this is cheating, isnt that what benchmarks are for, to utilize the cpu to its fullest to see how it performs? How are other phones running the benchmarks then, are they not using all cores to max frequency?

It because the CPU not acting like should by adjusting it self to stay in a power and temp target. Bench mark boosting is nothing new AMD/ATI, Nvidia and intel have all done it in the past.
