Benchmarks: PCMark 2002, Sandra 2003

PCMark can be used on desktop PC's, Laptops and even Workstations and tests everyday computing from home to office usage. PCMark specifically stresses the CPU, memory subsystem, graphics subsystem, hard drives, WindowsXP GUI (if WinXP is used), video performance and even laptop batteries.

Oddly enough, the Pentium 4 3.2GHz outperforms the Extreme Edition variant in PC Mark's processor benchmark. Further, the Intel chips handily trounce the Athlon 64 and Athlon XP processors.

The Extreme Edition establishes a lead in the memory subsystem metric, armed with dual-channel DDR400 modules. AMD's Athlon 64 follows, equipped with similarly specified memory modules of the registered variety. Third place goes to the Pentium 4 3.2GHz, while the Athlon XP 3200+ takes a fourth place finish.

Sandra is designed to test the theoretical power of a complete system and individual components. The numbers taken though are again, purely theoretical and may not represent real world performance. Higher numbers represent better performance.

It is very important to analyze synthetic benchmark scores with a hint of apprehension. After all, SiSoftware's benchmark description claims that its arithmetic tests derive their scores by running "some sequence of instructions." The multimedia and memory bandwidth tests should be more reliable, however, as they are based on actual benchmark tests.

Case in point: the Dhrystone test favors the Athlon XP 3200+ over AMD's Athlon 64 FX-51. On the other hand, the integer and floating-point multimedia tests demonstrate appreciable gains moving from the older K7 architecture to the newer AMD64 initiative. According to SiSoftware's documentation, the test's SSE2 code is optimized to run on Intel's Pentium 4, so it isn't surprising to see such a large deviation between the competing platforms. Hopefully, we'll see a new version of the benchmark with equal optimization at some point.
