For the past few weeks I’ve been living with an almost anorexically thin notebook. Lenovo’s Yoga 3 Pro, with its trademark “watchband” hinge is the thinnest full-fledged notebook I’ve ever used. It’s a 13-inch machine that weighs 2.62 pounds and measures a half inch thick. By way of comparison, Apple’s 13-inch MacBook Air weighs 2.96 pounds and measures .68 inches thick, with the 11-inch Air weighing 2.38 pounds but still measuring the same thickness. So yes, Lenovo’s new Yoga 3 is that thin and light. Part of the reason Lenovo was able to strike this super-thin pose with the Yoga 3 Pro, is its hinge design but also the fact that its internal specs, while plenty powerful, afforded Lenovo the ability to achieve good thermal characteristics despite very tight chassis constraints. The Yoga 3 Pro is one of the first notebooks to hit the market based on Intel’s new 14nm Core M Broadwell processor. In a nutshell, Intel’s Core M-5Y70 that’s powering the Yoga 3 Pro is a 4.5 Watt dual-core chip that competes performance-wise with their previous generation 15 Watt Core i5 dual-core processors. And in small, ultralight notebook designs, 10 Watts of thermal design power (TDP) headroom is a big deal.
