A reader replied that there is a newer version than I used for the original results posted here. Support of Altivec instructions dramatically increases performance with the G4 upgrade versus a G3 in this test. Within days they released an updated Cinebench 2000 which I used for all the tests below. For a full explaination of the benchmark and how to read the results, see this page . All tests were run at 1024x768, millions color mode.
Longer bars are faster.
Note the disappointing results with the Voodoo5 as far as OpenGL mode performance. It was slower than Cinema's software mode. Software mode reported very slightly higher results with the Voodoo5 installed than with the Rage128. I assume from these results CineBench does not take advantage of Altivec, but the faster PIII CPU and 4x AGP GeForce2 card also was a factor I'm sure. 32MB DDR arrives, I'll be running CineBench tests on it to see how it compares.
