It claims that Samsung has designed the device to be able to recognise when most popular benchmarking tools are running.
When the Samsung Galaxy Note 3 recognises the app as a benchmarking too, it begin running with “CPU [locked] into 2.3 GHz mode and all cores are active”.

However, when a non-recognised benchmarking app is ran, “the CPU is allowed to idle, shut off cores, and switch power modes, the same way it does in any other app.”
Ars Techinica dug deeper into the phone’s systems after initial benchmarks came back significantly higher than expected. It is said to have significantly outperformed similarly specced devices.
The site said the the tweaks meant that the phone was scoring 20 per cent higher on Geekbench than customers could realistically expect to see themselves.

“The difference is remarkable,” the site wrote. “In Geekbench’s multicore test, the Note 3’s benchmark mode gives the device a 20 per cent boost over its ”natural" score.
"With the benchmark boosting logic stripped away, the Note 3 drops down to LG G2 levels, which is where we initially expected the score to be, given the identical SoCs.
“This big of a boost means that the Note 3 is not just messing with the CPU idle levels; significantly more oomph is unlocked when the device runs a benchmark.”

The site also tested other popular benchmark tools. It found that Linpack’s figures were boosted by “about 50 per cent”.
At the time, it defended its actions saying that some of its own apps were able to lock the cores too and so it was only attempting to accurately portray how its own apps would perform.
However, Ars Technica has alleged that the file controlling the benchmark tweaking only refers to benchmarking apps and none of Samsung’s own apps.
