I've been researching and shopping around for notebooks recently, with a mind towards purchasing a unit which balances portability and power, and allows for gaming on the go. I'm a long-distance train commuter (on trains which don't happen to have outlets), so I spend a *lot* of my life with only battery powered electronics to entertain me (or serve as a vehicle for doing work).
The problem appears to be this: while we have a fair selection of affordable 14" laptops, often with the 630M, 640M or 650M providing dedicated graphics capable of playing recent games, user experiences seem to indicate that throttling results in most of these units' dedicated graphics becoming more or less dead weight when on battery
. Benchmarks like these
show a fairly powerful unit slowing to a crawl on battery, for gaming purposes, with its dedicated graphics performing *worse* than mid-range integrated graphics. In my scenario, there is no reason for the dedicated graphics to exist at all, if this is the case. The Lenovo forums, likewise, seem to be full of people complaining of their Y480/Y580 being unusable for gaming purposes when not plugged in, and with no available solution.
So my question is, does anyone have experience with, or know of, a current notebook unit or configuration which actually benefits from its dedicated graphics while on battery? For my purposes, a unit's performance while plugged in (but only while plugged in) is completely meaningless. I have my own workstations at home and at work. I don't need to use a laptop any time when I've got an outlet. Is anyone building portable computers which can game portably?
