I sort of get why Google opted for an Intel Core i5 processor. It gave the company the muscle needed for the Chromebook Pixels' 2560 x 1700-pixel screen. The MacBook Pro with Retina Display also uses a Core i5 CPU with Intel HD 4000 graphics to power its 2560 x 1600-pixel panel. The problem is that while the MacBook Pro has room for a heftier 74 watt-hour battery, the Pixel makes due with a 59 Wh battery. In our tests we saw a huge difference in endurance between the two machines: 7 hours and 38 minutes for the MacBook versus just 3:54 for the Pixel. A switch to Nvdia's more efficient Tegra 4 processor would allow Google to offer a lot more juice while upping the graphics performance—all without bloating the beautiful chassis.
