9800 GX2与8800 Ultra等长

NVIDIA的GeForce 9800 GX2和AMD的Radeon HD 3870 X2类似，都是在一块显卡上集成两颗显示芯片，但HD 3870 X2是单卡双芯，9800 GX2则与此前的7950 GX2一样还是双卡双芯。这样一来，9800 GX2的厚度明显增大，但PCB板长度并无变化，和8800 Ultra一样都是28厘米。

把8800 Ultra和9800 GX2垂直放在一起对比也可以发现，二者的PCB板是完全等长的，不过由于后者加强了散热器设计，显卡的长度增加了3毫米，达到28.3厘米。

HD 3870 X2的实物我们已经见过，但具体长度还不得而知，只能看出已经超出了主板的宽度。有些消息称，其实HD 3870 X2的长度也是28厘米。无论如何，AMD的工作应该说相当出色，能在一块PCB板上集成两颗芯片并基本控制住长度，的确不容易。
