We took another look at Video Encoding performance with Windows Media Encoder 9.  Windows Media Encoder 9 is both SSE optimized and makes use of Hyperthreading.

Windows Media Encoder 9
Digital Video Encoding Test

In this test, we took a 416MB Digital Video file and encoded to WMV9 format.  Times were recorded in minutes and seconds.  Lower times indicate better performance.

First things first, this is obviously a Pentium 4 optimized application and all our P4 chips here left the Athlons in the dust.  The 3.2GHz P4 Prescott CPU just sneaked past the 3.2GHz Northwood and fell in right behind its Extreme Edition counterpart.  The 3.4GHz P4 EE clearly takes the lead with its high clock speed and 2MB L3 cache, besting the next fastest score by a solid 11 seconds.  When you are processing large video files like we used in this test (the clip is only a bit over 2 minutes long however), those extra seconds can begin to add up quickly.

Cinebench 2003 Performance Tests
3D Modeling and Rendering Tests

The Cinebench 2003 benchmark is an OpenGL 3D rendering performance test, based on the commercially available Cinema 4D application.  This is a multi-threaded, multi-processor aware benchmark that renders a single 3D scene.  The time it took each test system to render the entire scene is represented in the graph below (listed in seconds).  We ran two sets of numbers, one in single thread mode and one in the benchmark's multi-threaded mode, for our Hyperthreading capable P4 test systems.

 

Surprisingly, the P4 3.2GHz Prescott CPU falls apart here, losing handily to the 3.2GHz Northwood and almost to the Athlon 64 3200+.  Clearly the benchmark isn't benefiting much from larger cache sizes, since the P4 Northwood and Extreme Edition cores are neck and neck, clock for clock.  The results scale accordingly in the Multi CPU test, where Prescott falls well behind again.

SPEC Viewperf
3D Modeling and Rendering Performance

We'll have a look now at something a little more diverse and "industrial strength" with SPEC Viewperf version 7.1.  Viewperf 7.1 draws performance metrics on many data-points in several different OpenGL based applications from various ISVs (Independent Software Vendors). The SPECopc (SPEC OpenGL Performance Characterization) project group is comprised of companies like 3DLabs, Intel, AMD, NVIDIA, ATi, Dell, IBM, SGI, Sun Micro as well as others, and helps define and endorse what application viewsets are used in the SPECviewperf test.

Currently, there are six standard SPECopc application viewsets:   (courtesy SPEC.org)

  • 3dsmax-02, based on SPECapc for 3ds max 3.1 configured with the Open GL driver, includes three models containing an average of 1.5 million vertices each, and tests performance of scenes with different levels of lighting.
  • dx-08, based on IBM's Data Explorer application, has 10 different tests.
  • drv-09, based on Intergraph's DesignReview model review package, has five different tests.
  • light-06, based on Discreet's Lightscape radiosity application, has four tests.
  • proe-02, based on SPECapc for Pro/ENGINEER 2001, measures two models in three modes - shaded, wireframe and hidden-line removal (HLR).
  • ugs-03, based on SPECapc for Unigraphics V17, tests performance based on an engine model containing 2.1 million vertices.

 

 

Where Prescott may have fallen down in the Cinema 4D based Cinebench benchmarks, it makes up for in spades with SPEC Viewperf.  The new core bests even the high end 3.4GHz Extreme Edition P4 in almost every test, except for drv-09 (Intergraph DesignReview).  The margin of lead in the Lightscape test is remarkable when you consider how much faster it is versus a 3.4GHz EE CPU.  The Athlon 64s can't keep up, especially in ProEngineer (proe-02), which is a very popular CAD suite.  If you are into Workstation Design applications, such as those seen here in Viewperf 7.1, then the new Pentium 4 Prescott processor may be your best choice for top performance.
