1. An analyzing method for graphics process, comprising: providing a plurality of reference graphics application programs and a plurality of reference graphics parameters of each of the reference graphics application programs; grouping the reference graphics application programs based on the reference graphics parameters into a plurality of groups; training a classifying relationship between the reference application graphics application programs and the groups according to the reference graphics parameters; and analyzing a relative relationship between a plurality of loadings of a plurality of hardware components of a graphic processing unit and the reference graphics parameters by calculating weighting coefficients of each of the groups and the plurality of hardware components; wherein the reference graphics parameters include general parameters, geometry parameters, and fragment parameters, the general parameters being different than the geometry parameters and the fragment parameters.
