r520

The R520 (codenamed Fudo) is a Graphics processing unit (GPU) developed by ATI Technologies and produced by TSMC. It was the first GPU produced using a 90 nm photolithography process.
The R520 is the foundation for a line of DirectX 9.0c and OpenGL 2.0 3D accelerator X1000 video cards. It is ATI's first major architectural overhaul since the R300 and is highly optimized for Shader Model 3.0. The Radeon X1000 series using the core was introduced on October 5, 2005, and competed primarily against nVidia's GeForce 7000 series. ATI released the successor to the R500 series with the R600 series on May 14, 2007.
ATI does not provide official support for any X1000 series cards for Windows 8 or Windows 10; the last AMD Catalyst for this generation are the 10.2 from 2010 up to Windows 7. However, AMD stopped providing drivers for Windows 7 for this series in 2015.Using a Linux distribution a series of open source Radeon drivers are available.
The same GPUs are also found in some AMD FireMV products targeting multi-monitor set-ups.
