The SPECviewperf® 2020 v3.0 benchmark, released on December 9, 2021, is the worldwide standard for measuring graphics performance based on professional applications. The benchmark measures the 3D graphics performance of systems running under the OpenGL and Direct X application programming interfaces. The benchmark workloads are called viewsets, and represent graphics content and behavior from actual workstation-class applications, without the need to install the applications themselves.
Major updates in the SPECviewperf v3.0 benchmark include:
SPECviewperf 2020 v3.0 supports all the features previously introduced in the SPECviewperf 2020 v1.0, released in October 2020:
The catia-01 viewset was created from traces of the graphics workload generated by the CATIA™ V5R12 application from Dassault Systemes.
Three models are measured using various modes in CATIA. Phil Harris of LionHeart Solutions, developer of CATBench2003, supplied SPEC/GPC with the models used to measure the CATIA application. The models are courtesy of CATBench2003 and CATIA Community.
The car model contains more than two million points. SPECviewperf replicates the geometry represented by the smaller engine block and submarine models to increase complexity and decrease frame rates. After replication, these models contain 1.2 million vertices (engine block) and 1.8 million vertices (submarine).
State changes as made by the application are included throughout the rendering of the model, including matrix, material, light and line-stipple changes. All state changes are derived from a trace of the running application. The state changes put considerably more stress on graphics subsystems than the simple geometry dumps found in older SPECviewperf viewsets.
Mirroring the application, draw arrays are used for some tests and immediate mode used for others.
The maya-06 viewset was created from traces of the graphics workload generated by the Maya 2019 application from Autodesk. The viewset includes numerous rendering modes supported by the application, including shaded mode, ambient occlusion, multi-sample antialiasing, and transparency. All tests are rendered using Viewport 2.0.
The catia-06 viewset was created from traces of the graphics workload generated by the CATIA V5 and 3DEXPERIENCE CATIA applications from Dassault Systèmes. Model sizes range from 5.1 to 21 million vertices. The viewset includes several rendering modes supported by the application, including anti-aliasing, shaded, and shaded with edges.
The energy-03 viewset is based on rendering techniques used by the open-source OpendTect seismic visualization application. Similar to medical imaging such as MRI or CT, geophysical surveys generate image slices through the subsurface that are built into a 3D grid. Volume rendering provides a 2D projection of this 3D volumetric grid for further analysis and interpretation. In addition to the volume rendering, the test includes both inline and crossline planes (slices in the X and Y planes). Also, for some subtests, “horizons” are present – these are geological strata boundaries of interest, generated by exploration geophysicists, and are rendered using textured triangle strips. The 3D datasets used in this viewset are real-world seismic datasets found at https://wiki.seg.org/wiki/Open_data". They were translated from their native SEG-Y format and compressed using JPEG-2000. Note: subtests 3 and 6 will have a score of 0.01 on GPUs with less than 3584MB (3.5GB) of framebuffer memory.
The creo-03 viewset was created from traces of the graphics workload generated by the Creo 4 application from PTC. Model sizes range from 20 to 48 million vertices. The viewsets include numerous rendering modes supported by the application. Order-independent transparency is enabled for all models with transparent components.
The 3dsmax-07 viewset was created from traces of the graphics workload generated by 3ds Max 2016 using the default Nitrous DX11 driver. The models for this viewset came from the SPECapc for 3ds Max 2015 benchmark and other sources. In order to best approximate real-world use cases, several tests incorporate multiple viewsets on screen, each using a different rendering method. The styles of rendering in the viewset reflect those most commonly used in major markets, including realistic, shaded and wireframe. Some lesser-used but interesting rendering modes such as facets, graphite and clay are also incorporated. The animations in the viewset are a combination of model spin and camera fly-through, depending on the model.
