看看ATi Custom Graphics的部份:
500MHz
10MB embedded DRAM
48-way parallel floating-point dynamically-scheduled shader pipelines
Unified shader architecture
500MHz的頻率和現在的R480差不多
個人認為R520應該會更高
10MB eDRAM則是XBOX所獨有
是用來實現沒有任何效能損失的FSAA
這在R520上可能看不到
比較值得注意的是48個Shader
而且竟然已經用上Unified shader architecture
也就是R520可能Vertex Shader和Pixel Shader已經合而為一了
由這點看來R520很可能會支援Longhorn中的WGF 1.0 (Windows Graphics Foundation 1.0)
也就是所謂的DirectX下一代
48個Shader個人猜想比較可能是24pixel-pipe, 單pipe兩Shader的架構
而Dynamically-Scheduled個人猜想可能是追隨nVIDIA在NV40上所採用的SuperScalar架構, 讓多pipe的scheduling更有效率
以上都是個人猜想啦
大家可以討論囉~~
