Claims like that are always subject to the benchmarks chosen. No one has ever claimed "x%" performance gain for a CPU and exhibited that across all benchmarks. They don't even exhibit that across all subtests in SPEC or GB.

Maybe they have a certain suite of benchmarks they use and 16% was the lowest gain. Maybe 16% was the average. Maybe 25% was the average and 90% of them were >15%. Taking marketing claims as gospel is what is "stupid", you always have to wait for actual performance data to see where the big gains are and where the glass jaws are.
