What's the difference between the various Radius 24 cards?

[pizzigri]

looks like a 24X, but the RAMDAC seems a 80MHz part - I cant read the ROM which is where most times the model is stated...
ETA Squinting real hard it loks like it is a 24x -however the 80MHz RAMDAC baffles me, should be a 110MHz? Maybe I'm mistaken?
