What is your application?  Where do these
300 pixels come from?

No Need to sort them, just need to track
which is the group with the current maximum.

There isn't any way to avoid checking all 30
groups (unless you have special knowledge).
Nor is there any way to avoid examining all
10 pixels in each group (unless you have
special knowledge).
