Behind The Silicon Curtain: Exclusive Test Of The P4/2666 With 533 MHz Rambus

Archiving: WinACE 4.1

Archiving is a very practical application. WinACE 4.1 was used under Windows XP to archive a 178 MB WAV file while the clock was running. The results are clear: none of the test candidates could hold a candle to the P4 CPUs with 2666 MHz, 2533 MHz and 2400 MHz. Even in this test, the importance of the 533 MHz memory clock makes itself evident. All chips that are not yet available on the market are indicated in red.

Video-Encoding MPEG-2: Pinnacle Studio 7

In creating an MPEG-2 video with Pinnacle Studio 7, the Pentium 4 CPUs with 533 MHz memory are clearly faster than the competition. The slowest candidate is once again the AMD Athlon 850, which we've used as a comparison. The performance of the AMD Athlon XP 2000+ is also quite impressive: together with DDR333 and the KT333 chipset, it is able to keep up with the competitors from Intel, which are clocked at much higher speeds. All chips that are not yet available on the market are indicated in red.
