Benchmarks are generally completely worhtless, meaningless numbers..lol. Its a complete waste of time to run them, if you ask me. Its a known fact that developers can produce ROMs/kernels that score high in benchmarks but perform sluggishly, and the other way around as well. You can run the same benchmark 3 times and you'll get different scores each time, it depends on so many random factors from the apps you have installed to how hot your device is.
Best thing IMO is to not bother with them. Just judge performance based on how it feels to you. Life will be so much less complicated
