Introduction



Today we have on our testbench ATI's brand-new Radeon X1950 XTX which is based on the "R580+" according to ATI.

The major new features of this card compared to the X1900 XTX are:
  • GDDR4 memory which is running at a whopping 1 GHz / 2 GHz DDR.
  • Improved cooling solution which allows quieter operation and better overclocking
  • Very competitive price of $449 / € 399 at launch.
What has not changed:
  • GPU Core clock. 650 MHz
  • Video Memory. 512 MB
  • Pipeline / Shader count. 16 / 48.
  • GPU Process size. 90nm.
  • Still Crossfire Master card required to run CF.
