r520 s ATi R5xx w/ Threading Dispatch Unit

Before the data comes from the setup engine to be processed in
the pixel Shader engine, it will meet an "Ultra" threading dispatch processor.
It’s a key part of the chip that will tell R520 data where to go, and the data
will hear and obey. Each of the Rx5xx chips will have this Ultra threading
dispatch processor that will process the data prior to sending them to the
pipes.
