SPECgpc® project group

The SPECgpc® (Graphics Performance Characterization) project group, founded in 1993, is part of the SPEC Graphics and Workstation Performance Group (SPEC/GWPG).

The project group provides unambiguous methods for comparing graphics performance across vendor platforms, operating systems, and windowing environments. The intention of the SPECgpc project group is to characterize graphics performance for computer systems running professional applications, not to measure overall graphics performance.

Defining Performance

The SPECgpc project group has established the following goals to define performance:

  • To permit standardized performance measurement and evaluation by creating unambiguous, vendor-neutral measures for product evaluation and comparison.
  • To provide mechanisms that enable vendors, customers and others to perform their own performance measurements and evaluations.
  • To provide formal beta and final software releases to the public in a timely fashion.
  • To contribute to the coherence of the field of performance measurement and evaluation so that vendors will be better able to present well-defined measures, and customers will be better able to compare and evaluate vendors' products and environments.


The SPECgpc project group develops and distributes the SPECviewperf® benchmark, which measures the 3D graphics performance of systems running under OpenGL, DX and other application programming interfaces (APIs).

Structure and Membership

The SPECgpc project group is a non-profit group whose general costs are paid primarily by SPEC/GWPG membership fees or dues. Any company, individual, institution or other group can become a sustaining member at any point in the development phase by remitting these dues. An appeals process has been established through which any interested or affected party may register and have heard a complaint concerning committee action or inaction. The principles of due process and antitrust compliance are adhered to by the SPECgpc project group at all times.
