來分析一下戰力吧..

拉拉比一個核心有16個浮點運算單元

最小單位8核心
時脈約 2000Mhz

大約等效128核心

8核心估計稍微比8800Ultra強一些(以運算量來說)

所以估計架構最大規模的32核心可以做掉 512 Shader的G300

但是到2011年,啥都很難講

搞不好到時候AMD隨便一搞 出手就是4000Shader...



Thread dispatchers !

8核心估計稍微比8800Ultra強一些(SP or DP )

所以估計架構最大規模的32核心可以做掉 512 Shader的G300--> (Backend capability ???) AA& AF


32/64 Core Larrabee +512 bit SIMD+ P54C + Ring Bus + 768bit GDDR5( Yes !) --> Unknown performance ( Three reasons ! )

1. Driver Team -> 3DLab

2. Software shader & patent issues

3. Cost(FOB) & Performance

G80 8 Core MIMD (8X16)----> G92
G200 10 core MIMD (10X24)--> G30X
RV770 10 core SIMD (10X16)----> RV830
RV870 20 Core SIMD (20X16)----> RV9XX ( Single Die)

If I seem equal to the occasions, and ready to face it when it comes, it is because I have thought the matter over a long time, before undertaking it.
