Central processor unit in Acer TravelMate 4072NWLMi is Pentium M740 1.73GHz, and in notebook Fujitsu-Siemens Amilo Xi 1546 is Core Duo T2400 1.83GHz.

More RAM memory we've got in Fujitsu-Siemens Amilo Xi 1546 - 2GB. Acer TravelMate 4072NWLMi came with 0.5GB.
Both notebooks use same RAM memory (DDR2).
Video card inside TravelMate 4072NWLMi is Intel 915GM and other laptop has ATI Mobility X1800 inside.
We like that video card on Fujitsu-Siemens Amilo Xi 1546 have its own video memory (256MB) and therefore its faster since it doesn't use main memory and mainboard controller is less loaded.
80GB were on its hard drives.
