I for the one, was in search for a good CPU.
For this, I would need to know an average CPU performance.
Not vs-vs, but actual list how CPU compares overall to other CPUs.

This is something many people do when they buy hardware.
Of course, this does not mean to represent the details, but rather overall performance for generic tasks.
Its meant to allow quick decision to buy, not to buy.

How about throwing three-four single core, three-four multi core and two-three memory bandwith tests, and get a three-four digit value, higher-better, which would present this CPU average performance index.
When make a table at openbenchmarking org, with ability to browse this list and sort it - name, higher performance, lower performance and eventually current market price as link for shopping.

Also, as there is a lot of tests already, the table should actually be already possible.
