Panic not, the helpful people at NotebookCheck have made a benchmark list of most (if not all) laptop CPUs - see click here. The better the CPU the higher up the list it is.
To go to the ones you need to look at quickly, do a Ctrl+F in your browser & enter the processor model (e.g. 330M) in the search field & press Enter.
Most of the CPUs you mentioned will be virtually the same in most everyday tasks. So tell us if you plan to do anything out of the ordinary or power-hungry (3D games / video-editing / similar) with the new laptop. And also your budget. And why a laptop & not a desktop? G
