I typed "Marathon Quadra 630" into Google to see if anything came up, to verify, in a way. From what I can remember, the 630 came with a special graphics acceleration chip. (I think it was called the "Valkyrie.") My best guess is that when Marathon was published they decided to use the features of this chip.
