PCMark 2002 is a synthetic benchmark that utilizes standard desktop functions like JPEG Decoding, Audio Compression and Text Search.  The scores are a relative reference metric and are very repeatable.

More synthetic testing



Here we see a similar picture to what we saw in the Sandra CPU tests, with the 3GHz P4 falling in slightly behind the 3.06GHz test systems, in the CPU performance module.  However, take these scores with a grain of salt, as they are only scaled metrics of relative performance, rather than scores driven by real world application code.  Also, the slight edge that the Granite Bay Asus P4G8X holds here, is due to its more aggressive timings, as set by Asus at the factory, versus the ever stable and conservative Intel motherboard implementations.



Higher Scores, In Frames Per Second , Mean Better Performance


Here we've taken a 20MB MPEG file and converted it to DivX format with XMPEG.  Video encode processing requirements are significantly taxing on memory and overall system bandwidth.  This is an area where the Pentium 4 shines, and with an 800MHz System Bus, it shines even brighter, besting its 533MHz 3.06GHz cousin by about 5%.  The Athlon XP 3000+ on the other hand, is left in the dust, at only 65% of the P4 3G-800's speed.  In this test, the Athlon XP 3000+ performs more like a "1900+".
