http://news.mydrivers.com/pages/20040330234314_66284.htm#com ATi今天在官方網站上無意泄漏出R42機密文件，根據這份文件，R420將部分支持Shader3.0 技術標準（nVIDIA的NV40將完全支持Shader3.0），ATi將在R5xx系列圖形芯片當中添加對 Shader3.0的完全支持，ATi目前關注R420現有技術性能的提昇。ATi也在文檔當中提及微軟將在Longhorn當中內建的DirectX 10，DirectX 10將內建Shader4.0技術。另外，ATi在文檔當中說明年內將推出搭載512MB顯存的圖形芯片，但不會是R420。 http://news.mydrivers.com/pages/images/20040330234258_29589.gif

Even some game : developers and customers received 300MHz samples with an 8x2 marchitecture.
