在Rage3D論壇 那裡看到一個對ATI內部好像頗清楚的人透露, 在最理想的情況下X800XT的效能可能會是9800XT的2.5倍.....哇!!

看過這個討論串後, 推測的效能比較, 可能是:
X800XT > X800Pro = 6800U > 6800NU >X800SE = 9800XT


其中有一段他po的內文
--------------------------------------------------------------------
well for starters....

9800XT = 412/380 8 pipelines

Bandwidth =24GB
Fill Rate =3200Gpixels

X800XT = 500/600 16 pipelines

Bandwidth =38GB (if they go with 500hz ram then 32GB)
Fill rate =8000Gpixels

Thats a Raw 250% increase in Fill rate and a Raw 60% increase in Bandwidth.

Not taking into account the other improvements to the Memory Controller, AA, AF, pixel Shaders, Vertex shaders and additional features....

You are looking at a product with no CPU limitations figured in that is between 200-250% faster just to start out. Then if the Clock speeds are actually increased.. like perhaps 550Core and 500-600 Ram its even a little higher.....

Bottom line?

In simple terms if Game X gets 60 FPS on the 9800XT then in an ideal enviornment it should get 150 FPS on the X800XT

所以X800XT可能會比6800u更快!!!
