DirectX 8 Games: 3D Mark 2001 SE
The 3D Mark 2001 determines DirectX 8's Direct3D performance under Windows XP. This test makes it clear that both systems - the AMD and the Intel - are pretty much on a par with one another despite different CPU clock speeds. In both instances, onboard graphics is a far cry from the AGP graphics performance.
