SPECopc demonstrates SPECviewperf 9

Latest industry-standard benchmark includes new viewsets;
features that tighten correlation to performance in real world

LOS ANGELES, August 3, 2005 – SPEC/GPC’s OpenGL Performance Characterization (SPECopc) project group today announced and demonstrated SPECviewperf 9, a new version of the standardized performance evaluation software for systems running popular CAD/CAM, digital content creation, and visualization applications. The announcement was made at a press conference during SIGGRAPH 2005. SPECopc expects the new software to be available within the next two to four months.

SPECviewperf 9 will include at least three new or updated viewsets – the test files that represent a similar mix of graphics rendering and manipulation found in actual applications. Currently planned viewsets represent recent versions of Maya, VisMockup, 3ds max, and UGS NX3.

A significant new feature change in SPECviewperf 9 is the ability to use glDrawElements instead of glArrayElement within the Maya 6.5 viewset. With the change, SPECviewperf now follows the same OpenGL command stream as the Maya 6.5 application. Other changes enable memory use and allocations within SPECviewperf 9 that better follow the application.  Vertices can be shared within glDrawElement and glDrawArray primitives, for example, as they are in the actual application.

With SPECviewperf 9, SPECopc has also taken steps to ensure that 64-bit applications are truly being run in 64-bit mode, and not being handled in the 32-bit space. The change will make 64-bit performance measurements within SPECviewperf correlate closer to those found in day-to-day practice.

“SPECviewperf 9 might just give synthetic benchmarks a good name,” says Ian Williams, SPECopc chair. “We’ve taken a very good benchmark and made it better by bringing the testing environments closer to their corresponding applications. Updated viewsets such as the one based on Maya 6.5 are intended to exhibit the same differences in performance between various levels of graphics cards as shown by the applications themselves.”

About SPECviewperf

SPECviewperf measures the 3D rendering performance of systems running under the OpenGL application programming interface (API). The benchmark’s viewsets represent a similar mix of graphics rendering and manipulation found in actual applications. Current viewsets represent graphics functionality in CATIA, Pro/ENGINEER, SolidWorks, Unigraphics, 3ds max, Maya, EnSight and Lightscape applications.
