The argument is kind of strange. Samsung said on the matter:
This makes it sound like Samsung is saying that because benchmarking tests require the highest workload from the processor, that's what it gets. This would be a reasonable defense if it weren't for how the benchmarking cheats were discovered. Multiple sites have found discrepancies between Samsung devices running the official version of a benchmarking test as compared to a test that is renamed, because the devices have whitelists that target specific benchmarking apps.
This is not really a matter of devices working to peak when any and all benchmarking apps are run. Samsung and other OEMs are actively targeting specific benchmarking apps and modifying processor behavior when those apps are running. Simplified, if you change the name of Geekbench to 6eekbench, the system doesn't recognize the package and doesn't modify behavior. That sounds like cheating to us.
