It's much closer to the SpeedStar +. The SpeedStar 24 is basically a SpeedStar
plus with the same layout and the same ET4000 with a different RAMDAC capable
of 24 bit color @ 640*480, plus a different ROM to add a new mode number to
support this mode.
The SpeedStar 24X is really a completely different card designed around a
different chip, ie. the Western Digital 90C31 Graphics Engine + frame buffer
+ 24 bit RAMDAC chip.
But I do believe that all the SpeedStars, including the Stealth, do incorporate
the programmable clock synthesizers. There may be exceptions. If so, I'm
sure that more than a few people will append posts stating those exceptions. :)
