I'm convinced gcc (or clang) is used by many more people than Cinebench.

Anyway Cinebench is too much about FP to be in any way an average representation of
anything beyond rendering; can you point to a study of its characteristics to disprove
that? And even for rendering I guess most people now run renderers that use GPU
acceleration.

SPEC has a good advantage for benchmark specialists: source is available for study and its
characteristics have been thoroughly studied. It's not a toy for end-users such as
Cinebench. But as any benchmark it should never be used without running other benchmarks.

Cinebench is also a poor use for that as it doesn't stress enough the CPU. I prefer to use
programs such as prime95 for CPU stressing.

And as far as price goes, again it's not an end-user app or a toy.

Because you never saw that happen, it can't happen in a real world application?
