Comparison of Indigo2 to Compaq Gloria-L

Someone emailed me asking why their Indigo2/SolidIMPACT didn't boast Viewperf numbers that put the Compaq Gloria-L to shame. Examing the figures in closer detail shows why. Some Viewperf tests involve texturing (something SolidIMPACT does not support in hardware) and as a result the tests that do very well are masked out by the texture-based tests that do less well. In one case, SolidIMPACT performs 3 times better.

The results also show that, in some cases, IMPACT as a whole can be up to ten times faster than Compaq Gloria-L, a fact that the results-combining technique hides. A similar thing happens with SPEC.

I wish people on the newsgroups would take the time to study the details in this way as one can learn alot about the hardware one is interested in and improve one's statistical skills at the same time. Ok, I'll step off my soap box now... :)
