So what is this "maximum internal rate" and where have you heard about 
it? :-)

GPUs and DSPs have this "maximum internal rate" that is usually called 
the clock frequency. It has nothing to do with the sample clock and 
besides - the last time I looked, most chips ran at speeds a bit faster 
than 48kHz. ;-)
