64.0 GB/s of memory bandwidth, a 29% advantage over the X1900 XTX. The card was launched on August 23, 2006. The X1950 Pro was released on October 17, 2006, and was intended to replace the X1900GT in the competitive sub-$200 market segment. The X1950 Pro GPU is built off of the 80 nm RV570 core with only 12 texture units and 36 pixel shaders, and is the first ATI card that supports native Crossfire implementation by a pair of internal Crossfire connectors, which eliminates the need for the unwieldy external dongle found in older Crossfire systems.
