More about which performance
  1. It depends on the model,what models are you considering ?
  2. In terms of pure memory bandwidth I believe DDR5/128-bit beats DDR3/256-bit but memory bandwidth is just one of many factors that contribute to the performance of a video card and is fairly meaningless on its own. Tell us what specific cards you are considering.
  3. I think he just asking for general knowledge......

    I considering nvidia geforce gts 250 with ati radeon hd 5750 ??
  5. The memory bandwidth and overall performance of the HD5750 is slightly better than the GTS 250. The HD5750 is also DX11 while the GTS 250 is not and it is much more power efficient. I believe it also overclocks better as well.
  6. thanks jyjjy
