ATI Changes the X1900GT Specifications
cumprimentos
ATI plans to change the specification of Radeon X1900GT,from 575MHz Core/1200MHz Memory to 512MHz Core/1320MHz Memory.
One of the reasons is to clean up the stock for preparing the upcoming RV570 based Radeon X1950PRO in October.
ATI Radeon X1900GT is based on the latest R580 core with 12 Pixel Shader Pipeline, 36 Pixel Shader Processor (ALU) and 12 ROP. In the previous specifications, the high clock speed has a duty to compensate the performance loss due to disabled Pixel Shader compared to X1900XT and XTX series of video cards. The higher clock speeds of the X1900GT, also generate high heat dissipation that lead to a noisy cooling. Perhaps, the new specification could result in less heat dissipation, and quiet operation. To compensate the performance loss due to the 11% lowered core clock speed, the memory frequency is increased by 9.1%. According AIB, both version of X1900GT would ship together, and most manufacturers would not indicate such changes
