Hard Labor - The best CPU for MPEG-4

Curtains up for MPEG-4! Right now there is hardly a more interesting topic for the majority of PC-users than the creation of video sequences in the space-saving MPEG-4 format or conversions to this format. The available amount of video material for MPEG-4 which, e.g. from the Internet, is constantly growing. Even the very latest movies that are still unavailable in European movie theaters can be downloaded as MPEG-4 videos from numerous Internet sites. The data volume is no longer a problem: in the past a single film required several CD-ROM's in order to be saved as a video in MPEG-1 format, today however, up to 110 minutes of video material in high quality can be squeezed onto a single CD-ROM. In addition: writeable CD's are very inexpensive and are practically ideal for MPEG-4.

In order to create MPEG-4 videos, or to convert existing digital film material, a lot of CPU performance is required, more than any other application demanded before. In our previous article concerning MPEG-4 (MPEG-4: Copying a DVD video onto a CD-ROM) we confirmed that for example, the conversion of sequences in MPEG-2 format to MPEG-4 required enormous computing power and a lot of time. As a consequence, we subjected the current processors from AMD and Intel to a detailled test. The key questions that we were concerned with were: which processor is best suited to the creation of MPEG-4 sequences and how high is the workload for the CPU during playback? The test included Intel's Pentium III (Coppermine core) from 600 MHz to 1000 MHz, Intel's Celeron with 667 MHz and 833 MHz, AMD's Athlon from 1000 MHz to 1100 MHz and AMD's Duron from 700 MHz to 880 MHz. Let one thing be said in advance: the processor is never fast enough!
