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
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.
