On October 17th of 2006, only five months ago, ATI launched the ATI Radeon X1950 Pro. This new video card and GPU brought us X1950 series performance for a price that won’t break the bank at $199 MSRP. To enable this ATI cut the pixel shader processors down to 36 from 48 in the X1950 XTX. They also lowered the GPU frequency to 575 MHz from 650 MHz in the Radeon X1950 XTX and the memory frequency was lowered to 1.38 GHz. ATI kept the memory bandwidth the same with a 256-bit data path but cut the memory capacity in half to 256 MB.
