The key benefits of Alienware’s mid-sized Area-51 m15x gaming notebook are its reduced size and lower weight. The Dell comparison system has the benefit of a huge battery, but that battery must carry the burden of dual graphics cards. Will Alienware’s battery life boost its credentials as a viable portable system?
The Alienware m15x stands out with a 68% battery life lead over Dell’s big gamer, but the exact numbers are far more significant. Many of us believe two hours is the absolute minimum amount of battery run time required for mobile computing, and the Area-51 m15x easily surpasses that mark, where the Dell system fell behind. This is hardly a surprise, given that one is an actual laptop, while the other is more a desktop replacement not meant to be separated from its AC adapter for very long.
Mobile Mark’s DVD playback time is a little more ominous, since most movies run beyond ninety minutes. We certainly wouldn’t want to be stuck at an airport with a dead notebook after watching a movie on a plane.
SYSmark favors Alienware’s Windows Vista box in everything but the 3D benchmark, where Dell’s SLI configuration takes the lead.
