Before we start commenting on the obtained results let me briefly tell you about the test set we are using:

  • 3D Creation. In 3dsmax 5.1 application the image is rendered into a bmp-file while the user is preparing pages in Dreamweaver MX. Then the user renders 3D animation in vector graphics format. Here the major contribution to the final result belongs to 3ds max performance.
  • 2D Creation. Here the test emulates the user’s work in Premiere 6.5 when the user is creating a video from a few other raw videos and separate sound tracks. While waiting for the operation to be completed, the user is working on an image in Photoshop 7.01: modifies and saves it to the hard drive. Having completed the video creation, the user edits it and adds special effects in After Effects 5.5. The applications contribute to the final results with the following shares: 43.3% - Adobe Photoshop 7.01, 39.1% - Premiere 6.5, 17.6% - AfterEffects 5.5.
  • Web Publication. The user extracts files from a zip-archive and at the same time uses Flash MX to open an exported 3D vector graphics file. The user modifies the file by inserting other images and optimizes it for faster animation. The end-movie with all special effects applied is compressed by Windows media Encoder 9 for further Internet translation. Then the created web-site is put together in Dreamweaver MX, while the system is being checked for viruses with VirusScan 7.0. The major influence on the final result is made by Windows media Encoder 9 (56%), VirusScan 7.0 (30.4%) and Flash MX (9.8%).
  • Communication. Here the test models the user’s actions when he received a message in Outlook 2002 with a set of zip-archives. While the files are being scanned for viruses with VirusScan 7.0, the user looks through his e-mails and makes a few notes in the calendar. Then the user browses through the corporate web-site and a few other documents with the help of Internet Explorer 6.0. The biggest contribution to the overall performance index results from VirusScan 7.0 (80.8%) and Outlook 2002 (15.4%).
  • Document Creation. In this benchmark the hypothetical user edits a text in Word 2002 and uses Dragon NaturallySpeaking 6 to convert an audio-file into text document. The end-document is converted into a .PDF-file with Acrobat 5.0.5. Then the user creates a PowerPoint presentation basing on the prepared document in Power Point 2002. The percentage of applications contribution to the end index looks as follows: Word 2002 - 10.4%, PowerPoint 2002 - 16.7%, Dragon NaturallySpeaking 6.0 - 34.6% and Acrobat 5.0.5 - 38.4%.
  • Data Analysis. The user opens a database in Access 2002 and creates a number of requests. The documents are packed with WinZIP 8.1 archiving utility. The results of the requests are exported into Excel 2002 and then are used for a diagram. The major part of the performance index is determined by Excel 2002 - 76.6% and Access 2002 - 19.8%.

As you see from the results obtained there are tasks where LGA775 platform with DDr2 memory works faster than Socket 478 platforms using DDR SDRAM. For example, LGA775 Pentium 4 550 outperforms Socket 478 Pentium 4 3.4E in 2D Creation subtest where video and images processing is emulated. However, in general we see that the overall picture we have already seen in gaming application repeats: high DDR2 SDRAM latency results into a significant lag of the LGA775 processors behind their Socket 478 fellows working at the same frequency.

Now let’s sum up the results on a single diagram:

The highest performance belongs to the new Pentium 4 560 processor, which is a Prescott based solution working at 3.6GHz. This CPU manages to outperform all CPUs working in an i875P platform as well as Pentium 4 XE which working frequency doesn’t exceed 3.4GHz. I have to stress that according to this test Athlon 64 processors fall behind Pentium 4 processor family. It can be explained by the fact that due to Hyper-Threading technology support Pentium 4 is a little bit batter at parallel data processing. The user model created in the SYSmark 2004 set implies that the user works in a few applications at a time, which is actually very close to reality.
