ATI arguably started it all when they revamped its flagship card by outfitting it with GDDR4 memory and an improved cooler - the Radeon X1950 XTX. Now they are following up with a less powerful version that still falls into the high-end segment, but at a more accessible price. The ATI Radeon X1950 PRO has a new core designation (RV570) but like most 'new' graphics chipset released recently, it's based on the older R580 core. In fact, it has the exact same shader and pipeline configuration as its Radeon X1900 GT predecessor that was using a R580 core with a one operating quad disabled from the total possible of four on the full fledged R580 core..
