Re: Puzzling performance issue



No, I'm quite certain that the A105's Pentium M is operating at full speed, according to the power control panel (and the laptop is plugged in).

I was testing two laptops:

#1 2004 Toshiba A45-S121, Celeron M 2.8GHz, 128k Cache, 400MHz FSB, 256 megs single channel DDR memory.

#2 2006 Toshiba A105-S2712, Centrino Pentium M 740 (1.73GHz), 2MB Cache, 533MHz FSB, 1GB of dual channel DDR2 memory

Both systems running Windows XP SP2 Home edition.

I ran a benchmark performance test on both systems, the test was PassMark Version 4 (it was an optional component of Norton SystemWorks 2003).

I expected the A105 to do a lot better, but much to my surprise, the A45 did better on the performance test in almost all CPU and memory tests (disk I/O on the A105 (which has SATA 5400 rpm drive) was faster, and the video tests were a lot faster, but on all of the memory and CPU tests the A45 pretty much killed the A105).

Anyone have any idea why? As far as I can tell, the A105, which has Speedstep and other power savers, was running at full speed (it was plugged into the wall for the tests).


The A105 should have smoked the A45. The A105 CPU isn't stuck at 1Ghz for some reason, maybe having battery mode power saving settings in the AC power settings in Power Options?
