在内存子系统测试中，Cachemem的结果显示K8T890内存带宽更高，但是在Cache Burst 32测试和RMMA测试中，nForce4 Ultra表现很抢眼，它具备更低的延迟，显然nForce4 Ultra对CPU与内存子系统的优化更好一些。在综合系统性能测试Sysmark2004中，两者表现接近，nForce4 Ultra略胜一筹，其中的子项目的表现各有胜负，同样的结果表现在MCCWinstone中。Business Winstone表现反常，原因在于这个项目的测试结果表现不稳定，超过了允许的误差范围。最后的图形子系统测试中，K8T890和nForce4 Ultra之间的差异才表现出来，无论是合成类软件测试3DMark05还是真实游戏测试中，nForce4 Ultra都取得更好的成绩，看来对于游戏玩家来说nForce4 Ultra是正确的选择。
