Since Windows XP Pro 64-Bit was released, there has been a lot of speculation of whether it would help current gaming or anything else in general. I put both versions of the OS through a round of benchmarks to see if the 64-Bit does indeed offer any advantage.
To benchmark Half-Life 2, I used the Half-Life 2 Benchmarking Tool. The first round of tests, I used two built-in Demos, and then I created two myself and tested them on both platforms. Half-Life 2 is much more CPU intensive than other FPS out there, so I was interested to see if there would be any improvements here.
We can see that the Guru3D Demo played equally on both platforms, but the HardwareOC Coast demo averaged an extra 20 frames through both resolutions. This is the first sign of a gaming advantage with the x64 XP.
