The 2 higher-end models of the 4 have a featuer called X-RAM which is supposed to further increase performance. I have no idea what this is, but I guess we'll find out more at QuakeCon later this week, where Fatal1ty will probably be promoting it.
The only thing that I can think of regarding X-RAM, is that perhaps it is some onboard storage for audio samples so that you don't have to keep transfering them over the bus if you want to play the same sound effect multiple times. However, I'm not sure how you could get this to work transparently without any programmer support, so this probably isn't it....
