虽然Asus Extreme N7800GT-Dual是采用上SLi双显示卡协同运算技术,但由于被整合在单一的显示卡上,因此我们也把它当作为单一片显示卡,由于采用两颗显示核心,就算是现时最强的单芯片显示卡ATi Radeon X1800XT也无法与其相比。
虽则Geforce 7800GT核心只有20条Pixel Shader条水线及7个Vertex Shader引擎,相比Geforce 7800GTX拥有24PS/8VS架构为少,但由于时脉被提升至475MHz Engine/1260MHz Memory,因此Asus Extreme N7800GT Dual对比两片Geforce 7800GTX(430e/1200m)运作SLi,效能更是略微领先。
后记:
双芯片显示卡到了今天已变得没有意义,没有了当年的惊喜,已不能吸引途人的眼光,宣传能力大大削弱,性价比不高只限采用于支持SLi的主机板上,是一张市场价值不高的产品,实在想不通还有那一家厂商会继续这个亏钱的玩意。
