What it means
Modern GPUs and CPUs do not run at one fixed speed — they constantly raise and lower their clock speed (boost) based on how much temperature and power headroom they have right now.
More detail
The 'base clock' on a spec sheet is the guaranteed floor; the 'boost clock' is roughly the best case. In practice the chip sits somewhere in between, second by second — climbing when it is cool and has power budget to spare, easing off when it gets hot or hits its power limit. …
In the Blackbook
The deeper explanation continues inside the app. The Blackbook publishes its verdicts here — the full write-ups stay in the book, on your rig, next to your own measurements.
The Compy Blackbook holds 191 graded entries like this one, judged against your hardware — and every change it does make is reversible, with the receipt to prove it.
