我们获悉，在苹果电脑发布Mac OSX 10.5.2 Leopard操作系统之后，有人已经在这版MacOSX操作系统当中发现RV770图形芯片和RS780芯片组的身影。根据他们在Mac OSX 10.5.2 Leopard操作系统当中提取出的文档显示，RV770图形芯片已经可以在Mac OSX 10.5.2 Leopard操作系统当中，完成完整的Powerplay节电功能： _PHM_TF_RV770_EnableL0s _PHM_TF_RV770_EnableL1 _PHM_TF_RV770_EnablePLLSleepInL1 _PHM_TF_RV770_ProgramDisplayGap _PHM_TF_RV770_RetrieveDisplayConfiguration _PP_RV770_Thermal_Initialize PhwRS780_UnInitialize PhwRS780_Initialize PhwRS780_SwitchMemClk

另外，也显示，苹果有可能采用AMD的处理器和AMD的RS780芯片组，RS780芯片组当中将集成Radeon HD 2400级别的DirectX 10绘图核心。另外，AMD提供给Linux社区的最新图形芯片驱动程序当中，也发现RV770的身影。其中，RV770的硬件id是"0x1002, 0xaa30"，并且支持HDMI输出： + "{ATI, RV770}," + { 0x1002, 0xaa30, PCI_ANY_ID, PCI_ANY_ID, 0, 0, AZX_DRIVER_ATIHDMI }, /* ATI RV770 HDMI */ 我们将继续关注AMD ATI下一代主流产品RV770的发展情况。
