How to judge the performance of graphics card

Display chip, video memory bit width, memory size, graphics card workmanship.

Display chip: Normal video card of the same sequence, the larger the better the model, such as AMD's graphics card 6470 is better than 6370, Nvidia is the same, 460 better than 450,

Video memory bit width: At present, there are mainly 64bit,128bit,256bit (large and 512bit, and some 192bit,384bit these will appear in Nvidia's graphics card, AMD rarely basic. This parameter is also the larger the better, there are many candidates graphics card will not pay attention to this parameter.

Video Memory Size: This is the most intuitive, the bigger the better, there are many candidates graphics card only to see the memory size, this is wrong, because the memory is not good for performance.

Graphics card workmanship: This is not the main factor, but also can not be ignored, the work is not good, the graphics card operation may not be stable enough to affect performance, to determine the card simple have, see the card on whether the capacitor is all solid state, inductance is not completely closed and so on
