5. PCMark05

As with SYSmark 2004 SE, the focus is exclusively on performance for PCMark05. The benchmark includes individual tests that focus on CPU, RAM, the graphics subsystem, and hard disks. An overall system score is calculated from the four individual tests. However, if any portion of the tests cannot be run, an overall score is not computed. For example the graphics tests will fail when a specific graphics subsystem is unable to support a particular graphic function such as pixel shading.

PCMark05 scores were scaled from 1200 to 5500 points at the time the benchmarks were developed. Specific systems at the low and high ends of the PC performance spectrum define reference points for low (1200) and high (5500) ends of the PCMark05 point scale. Nevertheless, values higher than 5500 or lower than 1200 are possible.

PCMark05 Concluding Remarks

The individual values that PC Mark 2005 reports confirm our previous measurements. When all systems run using external power sources, performance differences are pretty marginal. That said, memory performance in the TX series is relatively modest, an outcome of Sony's decision to use the somewhat slower single-channel access mode for its RAM. This has a negative impact on the corresponding performance measurement for RAM, further mirrored in measurements for the graphics subsystem. (As in many lightweight laptops, the graphics subsystem claims a portion of system memory for its exclusive use.)
