Intel Core i7 920 Nehalem 2.66GHz Processor Review

Intel Core i7 920 Nehalem 2.66GHz Processor Review - PCSTATS
Abstract: If you're a computer enthusiast, you're likely already familiar with Intel's Core i7 processors, which have been widely hailed as the fastest desktop processors available on the market today. Introduced at the end of 2008, Intel's newest desktop processors are finally maturing and becoming more accessible in the market. It's time to take a look a fresh look at the Core i7 processor.

32-Bit CPU Rendering Benchmarks: POV-Ray, 3.7, SPECviewPerf 10

POV-Ray 3.7 Beta 30 Source: POV-RAY

Ray-tracing is a rendering technique that calculates an image of a scene by simulating the way rays of light travel in the real world. In the real world, rays of light are emitted from a light source and illuminate objects. The light reflects off of the objects or passes through transparent objects. This reflected light hits our eyes or perhaps a camera lens. Because the vast majority of rays never hit an observer, it would take forever to trace a scene. Ray-tracing programs like POV-Ray start with their simulated camera and trace rays backwards out into the scene. The user specifies the location of the camera, light sources, and objects as well as the surface texture properties of objects, their interiors (if transparent) and any atmospheric media such as fog, haze, or fire.

Lower Render Times, and higher Pixel Per Second rendering values are best. Pov-ray is multi-threaded.

POV-ray is a surprise win for the Phenom II X4 955 Black Edition. The Core i7 tends to excel in these kind of raytracing tests, but AMD seems to have out-optimized Intel here.

SPECviewPerf 10 Source: POV-RAY

The SPECgpc project group develops and distributes SPECviewperf, which measures the 3D rendering performance of systems running under OpenGL. SPECviewperf measures the 3D rendering performance of systems running under OpenGL. The SPECopcSM project group has worked with independent software vendors (ISVs) to obtain tests, data sets and weights that constitute what is called a viewset. Each viewset represents the graphics rendering portion of an actual application. The ISVs that develop SPECopc viewsets have provided percentage weights for each test for which a performance number is reported. ISVs have defined these percentages to indicate the relative importance of a test within the overall application.

Higher results are better.

I'll admit it: I have no idea what on earth SPECviewPerf 10 is actually testing, or what the different tests actually do. But here are some charts!
