The results of the mainstream cards agree with our supposition that the frame rate of Prince of Persia depends on the GPU’s shader domain frequency in the first place. The other parameters of the graphics subsystem such as the amount of ALUs and the width of the memory bus do not affect the performance much. Therefore it is logical that the GeForce 9800 GT wins in this category. It is closely followed by the GeForce 9600 GT but the latter’s bottom speed goes down below the acceptable minimum of 25fps at 1680x1050.
Neither card from the red team is competitive to Nvidia’s solutions in this test, at least with enabled 4x FSAA. Both have very low bottom speeds, and the Radeon HD 4670 also has a rather low average frame rate. So, neither the Radeon HD 4830 nor the Radeon HD 4670 is a good choice for playing Prince of Persia. You should buy faster hardware – a GeForce 9800 GTX+ or, better yet, Radeon HD 4870 or GeForce GTX 260 Core 216 – to enjoy this game’s visuals fully.
