Rendering BenchmarksBelow, we use Mental Ray 3.3.1 to render a particularly intensive benchmark scene (which you can download here). Maya exists in 64-bit binaries in various circles, but we have only been able to obtain a 32-bit license and thus a 32-bit version of MentalRay. Below, you can see how the 32-bit binaries perform on both 64-bit and 32-bit versions of SuSE 9.1 Pro.
The P4EE receives a large bonus with the L3 cache with MentalRay, although that only slates it even with our Athlon 64 3500+. Although floating point operations generally govern the behavior of rendering time, memory plays a considerable role as well; the on chip memory controller for the AMD chips show their true colors here. Below, you can see how the various processors perform under the ray tracing program POV-Ray.
POV-Ray shows almost identical scaling to the MentalRay benchmark. We also noticing a trend between the Athlon 3800+ and the Athlon FX-53. Even though they have 512KB difference in cache, many of our benchmarks aren't showing that the processor utilizes that additional cache to its advantage. There are enormous performance benifits by under 64-bit operation with POV-Ray.
