R520迷團

http://www.beyond3d.com/forum/showt...74&page=7&pp=25

1.ATI took the first shipment of packaged R520 chips back three days after X850 launched.(這我知道但拖到現在還沒好 :laugh: )

Unfortunatly, Rys, the concept falls down a little saying that its just one fragement quad as that would indicate that the ALU's are deep, i.e. operating in a single pixel with multiple instructions, which would go against the idea of "12 pipelines". I know where you are coming from, but in this case it more likely that the "pipelines" are no longer single quad pipelines, but pipelines that can handle multiple simultaneous quads.

3.R520會突然死亡--bbs.Gzeasy.com消息

4.到底AIB與Developer的意見為何差那麼多?

只能說，AIC與Developer要的東西並不相同....
不過上述的東西倒是蠻有趣的，感覺上這回R5x0的ALU似乎真的能以1ALU為單位做multi-threading，在多個quad裡面切換。
以往會認為這樣效率其實不一定會比較好....
