3ds max
We have used 3ds max in the past for CPU testing, but most of those tests have consisted of rendering only. WorldBench's 3ds max tests replicate an entire modeling and animation work session, stressing the graphics card as well as the CPU and the rest of the system.

Among the P4s, the Extreme Edition 3.46GHz and the 570J trade off as fastest, but the top AMD chips are even faster.

POV-Ray
POV-Ray is the granddaddy of PC ray-tracing renderers, and it's not multithreaded in the least, because it's designed to be a cross-platform application. POV-Ray also relies heavily on x87 FPU instructions to do its work, and it contains only minor SSE optimizations.

Clock speed is the best remedy for the Pentium 4's relatively weak performance with x87 floating-point math, as the 570's render time shows.
