CF-Bench is (mainly) CPU and memory benchmark tool specifically designed to be able to handle multi-core devices, produce a fairly stable score, and test both native as well managed code performance.

It tests specific device properties you do not regularly see tested by other benchmarks, and runs in a set timeframe.

It does produce some "final" scores, but as with every benchmark, you should take those with a grain of salt. It is simply not theoretically possible to produce a single number that accurately describes a device's performance.

You can find CF-Bench on Android Market, and there's a discussion topic on XDA-Developers as well: http://forum.xda-developers.com/showthread.php?t=1134768
