ATI Officially Releases New RADEON X850, X800 (AGP) -
The RADEON X850 is a native AGP 8x visual processor (
PR) family code-named R481 featuring the RADEON X850 XT and other models. The R481 is produced using 0.13 micron process technology with low-k dielectrics and can operate at up to 540MHz clock-speed. The RADEON X800 XL originally known as R430 is a native PCI Express visual processing unit (VPU) that uses ATIs PCI Express to AGP Bridge chip code-named Rialto, which allows PCI Express graphics processors to be used in AGP-based computers. ATI produces R430 using 0.11 micron process technology at TSMC. While this process technology does not allow extremely high clock-speeds, it gives ATI opportunity to offer the chips at lower cost compared to 0.13 micron fabrication processes.
