Intel’s intensive efforts to get software producers to optimise their program code for modern processors -- Intel CPUs, naturally -- bear ever more fruit. The MP3 encoder MusicMatch Jukebox has been optimised in version 7.0 for Intel’s Pentium 4, allowing the new 2,533MHz Pentium 4 to just beat the Athlon XP/2100+.
With a 46.5 percent performance difference between the Pentium 4/2533 (fastest) and the Pentium 4/2000 (slowest), using a fast chip in this area is well worthwhile.
The new 533MHz-bus Pentium 4 processors are also faster than the Athlon XP/2100+ at video encoding using the popular MPEG Encoder 3.5 from LSX. However, a Pentium 4/2400 based on a 400MHz FSB is slightly slower than the fastest AMD processor.
Comparing the time taken to produce a DivX video using Xmpeg 4.5 results in a clear win for the Pentium 4. The Athlon XP/2100+ needs 23 seconds longer and is therefore a good 12 percent slower than the Pentium 4/2533.
