16. 3D Performance Vs. Battery Rundown Time
It was interesting to examine how the far higher 3D performance of the TM803LCi impacts the battery rundown time as compared with that of the Thinkpad T40.
To measure this, we allowed the games demo from 3DMark2001 to run in an endless loop until the battery was flat.
Compared with IBM's T40, the battery rundown time of the Travelmate 803LCi is rather modest with excessive gaming. With its 15.1" display, the Acer notebook has a slightly larger display diagonal, however this does mean that it requires more power. Nevertheless, the main reasons for the significantly higher power consumption are due, first, to the 64 MB / 128 bit memory interface (IBM with 32 MB / 64 bit). Secondly, the log files reveal that the CPU is constantly maxed out in the TM803LCi during this test, whereas the Pentium-M in the T40 grants itself the occasional power-save interlude (with reduced voltage/ frequency).
