Besides low temperatures, another benefit of performance-reducing CPU throttling is increased battery life. It's always odd for a next-generation CPU to give up performance, but at least the Yogo 3 Pro delivers in the longevity department.
Using PCMark 8's battery run-down test, the Yoga 3 Pro easily beat the Surface Pro 2 and Surface Pro 3, as you can see in the chart below.
In PCMark 8, the Surface Pro 3 gave me about 141 minutes of run time with 18 percent of battery life remaining, for a final battery score of 9,863. The Surface Pro 2 was next up with 175 minutes of run time; 12 percent of battery life remaining; and a score of 11,350. The Yoga 3 Pro's final score was 15,224 after running the test for 208 minutes with 19 percent of battery life remaining. Basically, the Yoga 3 Pro and Core M somewhat vindicate themselves against the older Haswell-equipped Core i5 chips.
The bottom line
In the end, the Yoga 3 Pro is a worthy upgrade to the the Yoga 2 Pro and amazingly thin. But is it a Surface Pro 3 killer?
Although it's a tad heavier, it has better battery life and a larger and even more pixel-dense display. While I'm a big fan of the pen support in Surface Pro 3, I've never been happy with using it on my lap. The Yoga 3 Pro, on the other hand, with its more traditional laptop mode, works far better. So, yeah, maybe it is the Surface Pro 3 killer. Now we just have to wait for the Surface Pro 4.
