Relatively soon after the introduction of Apple M1 and of Zen 3, so around the end of 2020 / beginning of 2021, I have examined a lot the Geekbench 5 scores for them.

In the GB5 database there was a small number of results for *non-overclocked* Ryzen 9 5950X that were grouped around 1850, along with hundreds or thousands of bogus results, which had almost any value between 1850 and half of this value, plus many higher scores obtained on overclocked CPUs.

The benchmark values that corresponded to the 1850 score were perfectly correlated with the values measured by myself on my slower computer, which has only a Ryzen 9 5900X with slower than normal memory (DDR4-2667), and which has a GB5 score of about 1800, still higher than any Apple M1.

In the GB5 database, the single-thread results obtained on computers using Mac OS, Android or Linux have a much lower variance than the single-thread results obtained under Windows on identical hardware, and of the wide range of Windows results only the maximum values are similar with the values obtained under other operating systems.

There are a lot of sites on the Internet which compare CPUs using the *average* values of the scores from the GB5 database. This is just stupid and this method severely underestimates the performance of the x86 CPUs, which is pulled down by garbage Windows results, when compared with ARM CPUs benchmarked under MacOS or Android.

I have no idea why the majority of the single-thread GB5 Windows results are much lower than on Linux or other operating systems, but my supposition is that most single-thread Windows results are not really single-thread, because some Windows services or anti-viruses may wake up during the benchmark and slow down the CPU.

In conclusion, the right way to use the GB5 database is to scan it for the maximum scores and verify the measured clock frequencies in order to eliminate any overclocked results. It is more likely that those maximum scores will be found among Linux results, not among Windows results.

For many x86 CPUs, this GB5 database search is not easy, because there might be both thousands of too low bad Windows results and thousands of too high scores obtained on overclocked systems.
