ATi有R499图形芯片？

目前有人在ATi发布的Hotfix催化剂驱动程序当中找到了R499图形芯片的身影。在催化剂hotfix的某文档当中有以下字段：

"R499" = ati2mtag_R499, PCI\VEN_1002&DEV_724A

"R499 " = ati2mtag_R499, PCI\VEN_1002&DEV_724C

"R499 " = ati2mtag_R499, PCI\VEN_1002&DEV_724B

"R499 " = ati2mtag_R499, PCI\VEN_1002&DEV_724E

"R499 " = ati2mtag_R499, PCI\VEN_1002&DEV_724F

"R499 " = ati2mtag_R499, PCI\VEN_1002&DEV_7248

"R499 " = ati2mtag_R499, PCI\VEN_1002&DEV_7249

"R499 " = ati2mtag_R499, PCI\VEN_1002&DEV_724D

"R499 Secondary" = ati2mtag_R499, PCI\VEN_1002&DEV_726A

"R499 Secondary " = ati2mtag_R499, PCI\VEN_1002&DEV_726F

"R499 Secondary " = ati2mtag_R499, PCI\VEN_1002&DEV_7268

"R499 Secondary " = ati2mtag_R499, PCI\VEN_1002&DEV_7269

"R499 Secondary " = ati2mtag_R499, PCI\VEN_1002&DEV_726C

"R499 Secondary " = ati2mtag_R499, PCI\VEN_1002&DEV_726D

"R499 Secondary " = ati2mtag_R499, PCI\VEN_1002&DEV_726B

"R499 Secondary " = ati2mtag_R499, PCI\VEN_1002&DEV_726E

针对这个发现，有人认为这是Xeons的PC驱动程序代码，也有人认为R499图形芯片支持Shader Model 3.0，因为在inf文件的驱动程序缺省设置当中，R499的几何举证（Geometry Instacing）默认打开，这是SM3.0硬件的特征，在所有的SM2.x图形芯片当中，几何举证默认关闭。另外，R499的自适应抗锯齿功能默认也是打开，在其它R4xx硬件上这个功能默认是关闭。

R499究竟是何方神圣，看来要等ATi官方给出答案了。
