The SiSoft test shows that DDR333 memory is marginally slower than 400 MHz RDRAM memory (PC800). The outcome is different with the PC Mark 2002: here, the P4's DDR platform even outstrips the RDRAM system. As before, the RDRAM platform with its 533 MHz memory clock speed is still unmatched, this system winning by a length in every test. Even with the fastest DDR333 memory (CL2), the AMD Athlon XP 2600+ doesn't quite reach the performance of an optimally configured DDR-based P4 system.
