The score in large print at the top of the screen is your Geekbench Score for that benchmark, which is an overall score. The Geekbench Score is useful for comparing different devices quickly. Depending on the platform you're using, there may be some scores provided in the application to compare your result to, and you can also take a look at the Geekbench Browser for individual results or for average results on the Benchmark Charts. For example, you can look for the average score for your device on the Benchmark Charts to see how your device compares to the average example of its model.
When comparing scores, remember that higher scores are better and that double the score indicates double the performance.
I hope this helps! Let me know if you have any further questions about Geekbench.
