Any averages for values in the GB5 database are meaningless.

For any given processor name, there are 4 kinds of results in the database

1. Correct results, with the computer in the standard configuration and with the benchmark run correctly, e.g. not concurrently with other programs whose activity would diminish the scores. In all the cases when I have searched the GB5 database, the correct results were no more than 5% of the total number of results.

2. Bad results, with scores much lower than normal for that CPU, either due to junk software running on the test computer, or maybe due to hardware problems, e.g. a completely inadequate cooling of the CPU, as frequently encountered in some of the cheapest laptops.

3. Too high results, obtained on overclocked computers.

4. Fake results, where the name of the CPU to which the benchmark is attributed does not correspond to the real CPU ion which the GB5 benchmark had been run.


Any average computed over 1% to 5% of correct results and 95% to 99% of wrong results is meaningless.

The only way to use the GB5 database is to carefully examine every result and filter all the bad results.

One of the main ways to recognize the bad results is to look at the complete test results, which are now available only for those with registered accounts, and to examine the clock frequencies used by the CPU while running the benchmark.

For single-thread GB5, the recorded clock frequency shall match the maximum turbo frequency of that CPU. If it was higher, the result must be excluded due to overclocking, if it was lower, it must be excluded due to either bad cooling or junk software interference.
