Connect3D and Sapphire Radeon X1900GT face-off

In some areas, the R580-based Radeon X1900GT is faster than the card it is replacing. However, in other, less shader-intense titles like Day of Defeat: Source, the R520-based Radeon X1800XT is the faster of the two. This can be attributed to the architectural differences between R520 and R580.

The natural competitor for the Radeon X1900GT is NVIDIA’s GeForce 7900 GT, and across a range of games, it is very much a case of win some, lose some for both companies.

The GeForce 7900 GT is a very good overclocker, while the Radeon X1900GT looks to be a bit of a mixed bag at the moment. If you’re looking to overclock, we feel that the GeForce 7900 GT is the better deal if you find one at a good price. However, if you’re planning to run your video card at stock speeds the final decision will depend on the games you’re looking to play.
