Can't tell you anything about performance of either of these two.
With the introduction of the UPA bus things got better: Sun introduced
Creator/Creator3d and Elite3d. Of course, none of these graphics could
touch what SGI was putting out, but it was a valiant attempt. Creator3d
used the SPARC for geometry but had onboard Z-buffer calculations,
Elite3d had a full graphics pipeline but not much texture cache.
Can't say anything about the really off-topic stuff for the current
machines.

Yes, they made a bunch of different 3D accelerators during the 90s
(and most likely beyond, but I haven't been attending SIGGRAPH often
enough to say for sure). Ironically, they didn't start making good 3D
accelerators until they hired ex-Evans & Sutherland engineers. I can
concur that working at E&S was good training in 3D! They really knew
their engineering, its such a shame that marketing and management were
utter failures.

Is the CG13 accelerated? It's big enough (2 board and consumes 3 SBUS
slots) that it definately could be accelerated (and I know that it's
24bit).

I think I have one of these GP2 things... its a separate pedestal
enclosure with a VME card that goes into the main Sun box. It was
reportedly a dog. I have the pedestal and guts but not the interface
card. I would love an interface card, if someone has one :-).
Then there was the Leo/ZX option for SBUS.
I seem to remember the "Leo" being talked about while I was at E&S.

The GP2 reportedly sucked, compared to competitors at the time :-).

stuff for the current

The stuff I'm remembering is from the 1990-1995 period, so it would be
"apopros" vis-a-vis the 10 year rule, which isn't a rule, really more
a rule of thumb or a guideline, well not really a guideline, more like
a hint, well not really a hint, but whatever Jay says it is...
