i'd like to see simple GPU benchmark for testing basic values of graphic cards like:
Pixel Fillrate (MPixel/s) - think can be found in some 3Dmarks
Texel Fillrate (MTexel/s) - think can be found in some 3Dmarks
Triangle/Vertices Rate (M/s) - don't know how gpu makers measure this, cant remember any benchmark for this one...
Best will be based on Opengl 1.1 so also very old profi cards can be tested (3DLabs, Intergpraph and similar stuff) and test won't be tied to some version of DirectX.
Fillrates can be measured by really old, outdated and no longer supported SPECglperf - https://www.spec.org/gwpg/pastissues/Feb2_02/opc.static/glperf.htm , but results have too many variants of results (see attached result file as warning how it should not look) and wont work on modern systems.
This kind of benchmark would be usefull for diagnostics between theoretical values of cards and real scenario. Also for detecting of number texture units and ROPS on cards with unknown specs - getting often mixed info from various sources about these at mobile chips or OEM cards (GPU makers ignoring them mostly and won't release any closer info).
