Terragen 3

Website:Terragen 3

Planetside Software’s Terragen 2 is a highly realistic landscape generator used to create background images in films and games such as Star Trek: Nemesis, Stealth and The Imaginarium of Dr. Parnassus. Our script renders a single frame of a snowy mountain scene at 640 x 480 on all the available CPU execution units.

Cinebench R15 64-bit

Website: www.maxon.net

Cinebench uses Maxon's Cinema 4D engine to render a photo-realistic scene of some shiny balls and weird things (we miss the motorbike). The scene is highly complex, with reflections, ambient occlusion and procedural shaders so it gives a CPU a tough workout.

As Cinema 4D is a real-world application - used on films such as Spider-Man and Star Wars - Cinebench can be viewed as a real-world benchmark.

Power consumption

For the power consumption tests, we measure via a power meter at the wall, so the numbers below are of total system power draw from the mains, not the power consumption of a CPU itself. Measuring the power draw of any individual component in a PC is tricky to impossible to acheive. We use Prime95's smallFFT test to put the CPU under 100 load, while idle power results were taken with the PC sitting at a Windows Aero-enabled desktop.
