Inquirer talks about the future of GPUs :

ATI R600 will represent the last of it’s breed, the monolithic GPU. It
will be replaced by a cluster of smaller GPUs with the R700 generation. It takes
a good bit of software magic to make this work, but word has it that ATI has
figured out this secret sauce. R700 boards will be more modular, more scalable,
more consistent top to bottom, and cheaper to fab. In fact, when they launch one
SKU, they will have the capability to launch them all. There have been several
code names floating around for weeks on this, and we hear it is pretty much a
done deal. Less concrete is the rumour that G90 will take a similar path, but
things are pointing in that direction.
