Asus' new high-end laptop could finally be the traveler's best accoutrement, touting twelve-hour battery life
thanks to intelligent, second-by-second switching between the two GPUs and automatic, on-the-fly re-clocking of the Intel Core i7 CPU. All this also comes in with a price tag of just over $1,000. "ASUS's solution is different because it's user-transparent; even a novice user will get the fullest possible benefit because the laptop itself is deciding when to switch. The same principle applies to the dynamic CPU clocking. ASUS includes a desktop widget to track CPU clock speed. While using the UL80JT, I could see it moving up and down with what I did; up with program openings and CPU-intensive processes, and way down at idle. Between the GPU switching, dynamic clocking, and ASUS's other power management features, the UL80JT manages to consume less than half as much power as the unibody Macbook while browsing."
