Archiving Utilities

Although the shift to Prescott core has significantly increased the Pentium 4 performance in archiving tasks, the introduction of the new platform didn’t continue this tendency. Higher memory latency caused by the use of new DDR2-533 SDRAM resulted into a significant performance drop during data compression. For example, even the fastest in WinRAR LGA755Pentium 4 560 is still slower than the Pentium 4 3.4E working in an i875P based system. In 7-zip the new platform performs a bit better than in WinRAR however it doesn’t save the situation.

The reverse process, data decompression, requires high computing power from any CPU. That is why Athlon 64 is far ahead Pentium 4 in this type of tasks, and among Intel processors the best result belongs to Pentium 4 560, which is the today’s fastest NetBurst CPU as far as the core clock frequency is concerned.
