虽然ATI Radeon X800GT的核心被屏敝了一半的流水线,不过和Geforce 6600GT及Geforce 6800LE还是有一定优势,虽然6600GT拥有极高的频率(500MHz Core/1GHz Memory),但由于只拥有128Bit内存频宽,相反6800LE虽然拥有256Bit内存频宽,但频率却严重偏低(325MHz Core/700MHz Memory),因此X800GT在大部份测试中稳健地胜出。明显看到Geforce 6600GT因内存频宽不及X800GT而在较高的解像度及关启AA后严重下降,甚至比本来不及6600GT的6800LE反超前。而Doom3一向是ATI的弱项,则反映ATI于重视OpenGL的游戏环境下不及NVIDIA。
