!! This is an "upgrade" / "license file" for the normal CF-Bench program, you must already have the free version installed or nothing will happen !!
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.
