32x is actually two 32bit processors running together, like saturn. that would make them 64 <img src="graemlins/tickled.gif" border="0" alt="[Tickled]" /> but its not true.
its just like tg16, is really 8 bit. it just has 2 8 bit procesors so they call it 16bit.
its all marketing really, but noticed how they stoped marketing bits after n64. because consoles became more component based. like dreamcast is a 128bit processor and a 64bitprocessor (or something) and xbox is really only 32bit (its an intel processor)
it just goes to show you that 'bits' dont matter, they just define an age nowadays.
