[业评] 看很多人讨论wii2的gpu，我就wiki了r700，发现对应的是4开头的ati显卡

Additionally, IGN has learned that the system will be based on a revamped version of AMD's R700 GPU architecture, not AMD's Fusion technology as previously believed, which will, as previously reported, out perform the PlayStation 3's NVIDIA 7800GTX-based processor.

ign获悉wii2使用的是r700改版，而不是之前预测的Fusion。该卡比ps3的7800GTX强。
