Next, we ran 3DMark2001 SE (Build 330) at the benchmark's default resolution of 1024x768.  3DMark2001 uses the "MaxFX" gaming engine, from Remedy's very popular Max Payne, to simulate an actual in-game environment.  3DMark2001 also makes use of DirectX 8 Pixel and Vertex shaders, to stress the overall performance of a gaming system.  If you've ever looked at 3DMark2001's detailed results, you've seen that this benchmark is broken up into groups of "High" and "Low" quality tests.  With a high-end video card installed, this test scales upwards when faster CPUs and memory are used.  The final score is generated by taking the results of these tests and adding them together using this formula:

  • (Game 1 Low Detail + Game 2 Low Detail + Game 3 Low Detail) x 10 + (Game 1 High Detail + Game 2 High Detail + Game 3 High Detail + Game 4) x 20 = 3DMark 2001 Total Score

Benchmarks With 3DMark2001
Synthetic DirectX Tests

Within the past few days, an overclocked Athlon 64 took the top spot in Futuremark's ORB (On-Line Result Browser), posting the fastest 3DMark2001 score in the world currently.  Our results seem to confirm that the Athlon 64 burns right through the 3DMark2001 benchmark.  The FX-51 outpaced all of the other systems we tested, some by a significant margin.  It beat the 3.2GHz Pentium 4 Extreme Edition by 2.3%, the standard 3.2GHz P4 by 12.6% and the Athlon XP 3200+ by 17.4%.

Benchmarks With XMPEG v5.02 Using DivX v5.1
Video Encoding Performance

After burning through all of the gaming benchmarks, we did some video encoding with all four of our test systems.  To get these scores listed below, we took a 24MB, standard MPEG 2 format video clip and converted it to DivX format using v5.1 of the CODEC with XMPEG v5.02.  The results are reported in Minutes:Seconds, lower numbers equal better performance.

The Pentium 4's did well in this video encoding test.  However, the extra cache and lower latency didn't help the Extreme Edition or the Athlon 64 FX-51 very much.  With a 3 minute 34 second encoding time, the 3.2GHz P4 Extreme Edition was the quickest of the bunch, followed by the standard P4 and then the FX-51.  The Athlon XP 3200+ finished last in this test, but it was only 3 seconds behind the FX-51.

Benchmarks With Magix MP3 Maker 2004
Converting WAVs to MP3s

We also did some audio encoding with Magix MP3 Maker 2004.  This program can be used to convert, edit and manage digital music.  We took a 65 minute .WAV file and converted it to a 128kbps MP3 audio file.  The scores listed below (reported in Minutes:Seconds), represent the total amount of time it took to encode the .WAV file and create the MP3.  Lower scores equal better performance.

The results in the Magix MP3 encoding test look much like XMPEG's, but here the Athlon 64 FX-51 was much faster than the 3200+.  The FX-51's increased memory bandwidth and lower latency give it a solid boost in this test.  It couldn't catch either of the Pentium 4s though.  The P4 Extreme Edition was 5 seconds faster than the standard P4 and a full 27 seconds, or 37.%, faster than the Athlon 64 FX-51.
