Intel isn't the only chip giant championing battery life over performance this year. AMD has revealed Carrizo, a processor range that's focused heavily on extending the running time of performance-oriented laptops. While there will be double-digit boosts to speed, there's no doubt that efficiency is the bigger deal here. The new core architecture (Excavator) is just 5 percent faster than its Kaveri ancestor, but it chews up 40 percent less energy at the same clock rate -- even the graphics cores use 20 percent less juice.
