SPECviewperf Benchmarks



SPECviewperf is a portable OpenGL performance benchmark program written in C that was originally developed by IBM.  Further updates were made by SGI, Digital and other SPECopcSM project group members.  SPECviewperf runs on most implementations of UNIX, Windows NT, and Windows 95/98.

The SPECopc group has sought benchmarks that represent the OpenGL rendering portion of independent software vendor (ISV) applications.  In order to characterize the graphics rendering portion of ISV's applications, the project group has come up with a "viewset."

The five viewsets used by SPECviewperf represent relatively high-end applications which normally render large amounts of data, or data sets.  The viewsets almost always include lighting, smooth shading, blending, line antialiasing, z-buffering, and some texture mapping.



The following screenshots were captured by SPECviewperf during benchmark runs.  These are a only a sample of the multitude of tests that are conducted by SPECviewperf.

Specviewperf Benchmark Results


Note: These benchmark results would be deemed invalid by the SPECops committee and do not meet the requirements as stated in the The OpenGL Performance Characterization Project Rules.  Specifically, Section I.3.i which states that, "Differences to the frame buffer between immediate and display list modes must not exceed 0.01% of the number of pixels in the window."

This information appears in the log file generated by ProCDRS where it states the "percentage pixels different" for each test.  A link to the log files generated by each test appear following the detail results.

NVIDIA is aware of the deficiency and has already corrected the problem in their OpenGL driver.  This fix will be included in a future release of their reference drivers.

The detail results for each test and their corresponding logs can be viewed here: Official results for various CAD workstations can be viewed at the GPC web site.
