Pentium 4 with 2.4 GHz in the test: The new front runner


To further clarify the sense and nonsense of a faster processor in frequently used applications, we used WinACE version 2.11 at this point. The task of the program was to pack a 200 MB WAV audio file at the maximum compression level (at 4096k) as an ACE file.

Winace 2.11

As is easy to see, WinACE clearly belongs to the Intel domain. The 2.4 GHz fast Pentium 4 continues this tradition. However, the performance only increases by a barely noticeable 2.3 percent. The speed brake is hardly to be found in the processor, rather the rest of the system is slowly reaching its limits.


Of course we were allowed tothe processors also show what they're made of when encoding videos. For this, each of the opponents was allowed to bring a 451MB MPEG1 video into DiVX (MPEG4) format using Flask. The average frame rate achieved was recorded on paper. High quality bicubic filtering was used, with only the video stream being processed. The audio stream, however, remained unprocessed. MMX was used as iDCT, as all test candidates fully support this multimedia command extension. In addition to this, we also selected two iDCTs, each of which should unleash the performance of the processor by including the command extensions. For the Pentium 4 this meant the iDCT Reference SSE2, while the Athlon XP got down to business with the reference 3DNow.

Flask is one of the test programs that clearly benefits from the increased computing power. The performance increases by 8.6 percent with MMX and even 10 percent when using the SSE2 extension. We recently saw such a high increase in speed in the Sandra processor test Dhrystone. All in all, the Pentium 4 2.4 converts 10 images more per second than the AMD competitor does for the time being.
