A single-threaded benchmark that is around for quite a while. Many people used it in the past and it seems like a good benchmark to test integer performance. Note that CPUMark '99 likes L2-cache while a large L2-cache doesn't always improve performance in, for example, office applications.
I have used CPUMark '99 of processors ranging from Pentium 100 to quad-cores.
My benchmark method
Just launch CPUMark '99 and press 'Run Test'.
