There was, I believe, something that could be paired with a CG9 in the
Sun-3/early Sun-4 days. Ah yes, here it is: the GP2 graphics processor.
VME based, with Weitek engines.
Then there was the Leo/ZX option for SBUS.
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.
