Let's get one important naming issue out of the way first. ' R580+ ', as a specific name for the ASIC itself, doesn't exist. Look at the GPU of an X1950 XTX and you'll see plain old R580 laser-etched onto it. What we have, however, is a new revision to the silicon - A31 - to provide a number of tweaks. the name ' R580+ ' has been used internally (and occasionally externally) by ATi as an easy way to refer to this new product over its X1900 brethren.
