The pre-overclocked product from Foxconn is a little faster than the Gigabyte, which works at the frequencies of the reference card, in every case, save for 1920x1200 resolution. At the same time, the imaginary GeForce 7950 GT 256MB graphics card is always slower than its 512MB counterpart.
Like in the previous case, the pre-overclocked graphics card from Foxconn is always ahead of the Gigabyte GeForce 7950 GT 512MB, except for 1920x1200 resolution. But if we take the GeForce 7950 GT with 256MB of memory and clocked at the reference frequencies, we’ll find it is always considerably slower than the same model with 512MB of memory, even though the speed it provides is high enough for comfortable play.
The difference between the graphics cards from Foxconn and Gigabyte is mainly due to the difference in the speed of the GPUs in the game’s FP HDR mode. The increased GPU frequency of the Foxconn card makes the trick here. Both cards are slightly better than the Radeon X1950 Pro, but much worse than the Radeon X1900 XT. There’s no difference between the cards form Foxconn and Gigabyte from a practical point of view: both can be used to play in resolutions no higher than 1280x1024.
