Caligari TrueSpace 5.1
Despite the fact that TrueSpace 5.1 is a bit outdated, it is still one of the benchmarks of choice because of its true multithreaded nature that takes advantage of both dual core architecture and HyperThreading.
Four different scan lines show each of the logical cores in a dual core with HT enabled setup. In the case of AMD-powered systems, dual core processors will only show 2 scan lines.
Runtime in seconds of a render pass of Adam Trachtenberg's "Vases" scene at 1024 x 768 resolution with ray tracing enabled and 2 x antialiasing. Lower is better The FX-62 takes the lead. Once again, there is little difference between a 667 MHz memory frequency and the 800 MHz setting with the FX-62 processor having the benefit of the larger cache. In the case of the X2-5000 with the half-cache, changing the memory speed slows thing down quite a bit more.
Power / Renderpass
We took the runtime and multiplied it with the typical power draw during a rendering pass to see which CPU accomplishes 3D rendering in the most energy efficient way. The FX-62 and X2-5000 hold relatively solid placements in the lower (better) third of the field. Numbers used here only reflect the performance and power consumption at 800 MHz memory frequency.
