标 题: GTX660Ti显存瓶颈原型大暴露

Our last few comments concern the 660 Ti's 192-bit memory interface. Our
benchmarks show that this can really put Nvidia's GeForce GTX 660 Ti at a
disadvantage, even at 1920x1080 and without obscene texture detail settings.
Whether or not you run into a performance problem depends mostly on the
game you're playing. In general, though, the card really starts to run out
of steam at anti-aliasing settings at and beyond 4x MSAA. This is too bad,
since the GPU goes underutilized at that point. The problem is unique to
this card. None of the other Kepler-based boards experience it. We're not
saying the GeForce GTX 660 Ti is a bad card, but there are competing
configurations that demonstrate better balance.

发帖数: 7955 | 3 nvidia应该在主推TXAA。效果看着是不错，对显存带宽的要求应该没有MSAA高。问题是
老游戏都不支持TXAA，新游戏有多少支持TXAA也不好说。
