The SPECfp95 benchmarks don't focus on graphics tasks at all. They're
mostly numerical number crunching of various kinds. One test uses 32bit
fp I think, but if I recall correctly it's not the MADD-style math
found in geometry/lighting, which is what R5K is good at.

Depends on what you're doing. In some cases, yes. O2 is good at
complex media tasks, video as texture is cheap, accelerated imaging,
etc.

For example, I know one place which used an O2 to help do a live launch
of a new mobile model. A live feed of the boss speaking about the model
was mapped onto the 'screen' of a 3D real-time model of the mobile,
which was displayed on a big screen. O2 is ideal for this sort of
thing.

Indeed, O2 has the noise advantage, and certain models of disk are VERY
quiet indeed. I have a 9GB SCA in my gateway Indy which is so damn
quiet
that sometimes I have to walk over & listen just to be sure it's still
on! :D
