Harpertown: New 45nm Xeons from Intel
Posted on: 09/17/2007 05:00 AM

POV-Ray 3.7.0 beta 22
The Persistence of Vision Ray-Tracer creates three-dimensional, photo-realistic images using a rendering technique called ray-tracing. It reads in a text file containing information describing the objects and lighting in a scene and generates an image of that scene from the view point of a camera also described in the text file. Ray-tracing is not a fast process by any means, but it produces very high quality images with realistic reflections, shading, perspective and other effects.
I recently added POV-Ray to the benchmark suite as the latest beta releases have added 64-bit and SMP support. All results are from POV-Ray's default "Multi CPU Benchmark".



No surprises here. Harpertown nearly doubles the performance of Woodcrest again, and spanks the Clovertown Xeons handily.

Power Usage



When it comes to power draw, it is pretty much the same story as we've been seeing all along.

"Performance-per-Watt"



Faster doesn't always mean better when it comes to "performance-per-watt", but someone forgot to tell that to the Harpertown Xeons.
