gtx260+效能問題

有冇人知點解gtx260+既速度只係快gts250 20%既原因?

粒u唔夠推(好似IQ題…).

1, core clock + shader clock lower than GTS250 a lot ....
2, performance increase in high grade vs mid wasn't linear

you can check overclocked 260+ at near GTS250 clock performance

Man they're in totally different league....

GTS 250: 128SP, 256-bit Mem, 738/1100
GTX 260+: 216SP, 448-bit Mem, 576/1000

If you do simple math, in terms of computational power and memory bandwidth, 260+ wins 250 by A LOT.

Like the other member has said, it is either bottleneck in CPU, or using inappropriate testing methods (like using low quality settings with low resolution)

shader clock , rop speed and amount
260+ G200B vs G92 , only bandwidth / SP x2 , but others are lower
