Battery Performance and Portability Index
Just one look at the sheer size of the G74SX is all you need to know that it wasn’t built with portability in mind. Weighing a back straining 4.3kg, you probably don’t want to be carrying it around too much (or probably, not at all). In fact, we bet the only time you’ll be running the G74SX on battery is if there’s a power outage, in which case you’ll be relying on the unit’s 8-cell 14.4V 74Wh capacity battery.
|Specifications / Notebook||ASUS G74SX||Samsung Series 7 700G7A||Toshiba Qosmio X770|
|Battery||14.4 / 74Wh||15.1V / 89Wh||14.4V / 47Wh|
|Dimensions||325 x 420 x 21-62mm||407.5 x 267 x 39.8-49.9mm||414 x 274 x 28-61mm|
In our DVD video looping test to drain the system's battery (with screen brightness and audio both set to 50%), the G74SX lasted just over two hours, longer than both of its competitors and on par with the Dell Alienware M17X R3. Power consumption was about average for a 17.3-inch desktop replacement and slightly worse than Toshiba's X770, despite the longer battery life. It's not outstanding, but we would rank it as reasonable for a machine of this class and bulk.
With its bulky dimensions and heavy weight, the G74SX was never going to score well in our portability index. Even so, it fared slightly better than the X770 due to its longer battery life, and also beat out the even heavier Alienware M17X R3, which weighs a back breaking 5.3kg.
One thing we did find ourselves wondering is, just why is the G74SX so heavy anyway? It's not packing any bulky speakers, uses only a mid-range graphics card, and it doesn't have any special technology or feature. What exactly did ASUS put in there? We're not quite sure of that, but we do know why it's so thick. One of the reasons is to accommodate its special ducted exhaust system that's built into the unit and contributes to the fancy rear exhaust.
Nevertheless, despite this ASUS notebook having a Portability Index that's better than the Toshiba notebook, its weight is just too much for us to even consider ranking them on equal footing. Hence, we've marked down its portability score.
