No Intel proc with a U, T or Y suffix. These are all lower power versions that won't sustain high performance. You absolutely sacrifice battery significantly with anything else though when under sustained high performance, including strong AMD processors, but they may do a little better. Next is discrete graphics. If you just need multiple monitors, an Intel G CPU will usually do it. If you need discrete GPU, again you're going to sacrifice on battery. For longevity, you might want to consider a Xeon laptop. Lenovo has these, so they're one option. One measure of how much sustained performance a laptop can take is the charger wattage, usually buried in the spec sheet. In my experience chargers are rated only slightly higher than the wattage necessary to keep the machine going at top performance. A laptop with a low wattage charger is unlikely to sustain top performance for long. But it depends on your definition of "sustain". 10 minutes? Half an hour? Constant load of 60, 70, 80%? The charger heuristic just weeds out low power though. There's less of a guarantee that a higher wattage charger == higher sustained performance.
