Version: 2003
This benchmark is suitable for CPU's from 2000 and upwards to modern dual and quad-core CPU's. It will run quite slow on an Athlon 500 or similar but it can give a good picture of the performance between a single CPU of dual CPU (or either dual-core) system. Cinebench 2003 is great of testing performance between older and newer (up to octo-cores) processors.
My benchmark method
In the benchmarks I always used multi-CPU rendering if possible (see highlighted part in the screenshot). This is why dual-core CPU's score much better than single-core CPU's.
