HD Gaming Tests
In our on-going attempt to keep pushing the envelope on testing PC hardware, I have included three sets of benchmarks that were run at a super high resolution of 2048×1536. I included Half-Life 2, Far Cry and Call of Duty 2.
In Half-Life 2, the additional 256 MB of memory on the X1800 XTs and the 7800 GTX 512s are clearly outpacing the original 7800s from NVIDIA. The X1800 XTs in CrossFire mode have a 29% lead over the 256 MB cards but just barely fall behind the big-boys from NVIDIA.
With the frame cap of 100 FPS that is default in Battlefield 2, the differences between the three setups aren’t too extreme, though the 512s from NVIDIA have the advantage of a higher minimum frame rate and a higher average.
Call of Duty 2 also takes advantage of the 512 MB frame buffers on the X1800 XTs and the 7800 GTX 512s though again NVIDIA’s top card has a performance advantage over ATI’s latest cards. The X1800 XT CrossFire setup does beat the original 7800 GTXs by about 10%.
