The three systems are the 12.5" EliteBook 725, the 14" EliteBook 745, and the 15.6" EliteBook 755. All three of 'em are outfitted with AMD's new Pro APUs, which have 17-19W thermal envelopes fit for ultrabook-style systems. And indeed, HP says the new EliteBooks are only 0.83-0.85" thick, depending on the model.
Other perks for these machines include optional touch-screen technology, optional LTE wireless connectivity (only on the EliteBook 725), and optional 1920x1080 screen resolutions across the board. The EliteBook 745 and 755 can also be ordered with 1600x900 displays.
When these systems become available in June, starting prices will be $799, $739, and $749 for the EliteBook 725, 745, and 755, respectively. Yes, the smallest one will be the priciest of the bunch—though the differences aren't exactly big.
