很好的一篇評測，多謝
不過你給的數據有點太特殊了
9600p在1600x1200的解析度下開啟4xfsaa會效能驟降

The internal cache sizes in RV350 are reduced from R300, which is probably why there is a reasonably large disparity between the 9600 PRO and 9500 PRO with 6X FSAA enabled. Both 4X and 2X AA show the 9600 PRO very close in performance to the 9500 PRO, up until 1600x1200 where we see the now characteristic fill-rate performance drop off.
ATI state that as this is a mainstream part, they have put their efforts into optimising, as much as possible, non-AA rendering and AA rendering up to 1280x1024 with 4X.

大意是說推測是填充率太低的關係
ati官方聲稱9600pro是為不開啟aa或是最高1280x1024開啟4xfsaa做優化
(翻得很爛，看原文唄
)
事實上1600x1200並不是9500p和9600p開啟4xfsaa能夠handle的
1280x1024 4xfsaa+8xaf用9700p也不是每個遊戲都跑得順
