Noticeably lower performance index of processor unit

[BeLzEbUb]

Hello, if I do complete CPU benchmarks only in PT I'm getting repeatedly noticeable lower values (about in 6600-6800 range) than is the common average (>7900 points). What might be on cause or is this influenced by other factors/MoBo/components? Any chance to tune it to perform on usual performance indexes?

Temperature, voltage and clock seem all be in good operating ranges.

If this is a laptop, check the power management setting, make sure you aren't running on battery power. Also if you were running 32bit Windows, this could be the cause.

Thanks for the reply, this is a laptop. And unfortunately none of mentioned apples to my situation. Laptop is new so there's no junk yet, having new drivers and 64bit OS.
- running on AC main, power profile balanced which allows 100% CPU utilization
- No processes that could throttle performance test
- also it is supposed no other components should be influencing the index because this was only CPU tests.
