When we look at graphs for GPU and CPU processors processing power, there is a section where they talk about one percent lows, what is that?
In: 1
It’s the statistical concept of percentiles.
While you run a benchmark, your testing cpu/gpu is generating some number of frames every second. Let’s say that this benchmark ran for exactly 500 seconds, so we got 500 fps datapoints. We take those values and sort them from lowest to highest, and then look at the value that’s 1% away from the low end — the 5th value. That’s the 1% low (or 1st percentile).
It’s an informative statistic in this case because really bad lows point to occasional disruptive stutters, which of course make for a bad experience.
