ATI’s solutions cannot win in the mainstream category, either. Although the Radeon HD 4830 is almost as fast as the GeForce 9800 GT in average frame rate, its bottom speed is lower, especially at 1680x1050. The difference of 5fps is not too big, though.
The Radeon HD 4670 looks good at 1280x1024 but loses its ground at 1680x1050. Having a bottom speed of only 12fps – twice lower than the speed of the GeForce 9600 GT – this card cannot ensure smooth gameplay. Its 128-bit memory bus makes it uncompetitive against the GeForce 9600 GT which has a 256-bit memory interface. On the other hand, it is not positioned as such a competitor, coming at a much lower price. The Radeon HD 4670’s market opponent, GeForce 9500 GT, has only 32 shader processors and is very poor in 3D games.
The GeForce 9800 GT is the best choice in this price category but the Radeon HD 4830 is almost a worthy substitute for it. The GeForce 9600 GT wins in the bottom price segment but you can also choose the Radeon HD 4670 if you are not going to play at high resolutions.
