.0b and 3D Studio Max 4.2 Rendering"> 3D rendering engines puts heavy emphasis on a CPUs FPU performance. Its surprising that the 3D Studio Max test saw such heavy variance among processors on the same chipset. It really battered the Soyo--which until this test seemed to be fairly adept at processor intensive applications under Windows 2000. The 3D Studio test uses the architectural model from the old SPEC 3D Studio 3.0 benchmark. There are over 600,000 polygons in this particular scent--enough to really hammer both the CPU and the memory subsystem. The Lightwave raytrace test is also quite floating point intensive, but has relatively few vertices. So most of the time is spent in the rendering codepath, not in moving data to and from memory.
