h well not really as we have different CPU's from Intel and AMD and we want to see how these benchmark without benchmarking the apps(s) as apps are many and benchmarking them all against all the apps is not possible.
Published Spec benchmarks are valuable in this fuzzy context.
Once you have your application benchmarked, tools like "lmbench" may help you understand what the win/loss keys are.

More important than hardware can be your choice of compiler and IO (disk)... When looking at 'spec' benchmark results pay attention to the choice of compiler AND the hardware bits surrounding the CPU.
