- That's what I am telling. It measures benchmarks of complete systems.
- That includes things like system overhead or quality of the compiler
- used.
-
- It is no precise measurement of the processor itself. It doesn't say
- much about what you can expect from a different system using the same
- processor.

-
- There are benchmarks that depend less on the system but mostly on
- the CPU and memory system including external caches. And then there
- are artificial programs that just measure different instruction sequences
- or very basic algorithms. These can be used to interpolate results
- for different environments of the same CPU.
-
- Still, these tests do not say much about system performance but they
- tell you how fast a system _could_ be with a certain CPU.
