Data Compression - WinAce 2.11
Despite the very extensive compression algorithms used by standard packers such as WinZIP, WinRAR or WinAce, these programs are very frugal. The Celeron 1.7 is just as fast in this benchmark as the Pentium 4 at the same clock speed.
MPEG-4 Encoding: Flask 5.01
It makes no difference whether you have a Pentium 4 or a Celeron under the hood when processing video streams - the larger cache on the P4 hardly matters.
MP3 Encoding: LAME 3.92
With a Pentium 4, Lame converts WAV music files into compressed MP3s somewhat faster than with a Celeron.
