Samsung reportedly will not offer Ultrabook models with Intel's power-efficient Haswell processors until the fall. Still, with battery life rated at about eight hours of continuous use, the ATIV Book 9 is no power hog. While its numerous Ultrabook models are perhaps a bit more complicated to sift through than Apple's, Samsung does offer more flexibility in terms of processor and graphics options than Apple.
All models from both companies have two cores. Between its Core i5- and Core i7-based models, Samsung's clock rates (without Turbo Boost) range between 1.7 GHz and 2.0 GHz. Its most powerful, the ATIV Book 9 NP900X3E, comes with the 2.0GHz Intel Core i7 3537U. Meanwhile, Apple has Haswell in all of its 11-inch and 13-inch MacBook Air models, and boasts major improvements in battery life. Base models are built with the 1.3 GHz Intel Core i5 processor with a maximum clock rate of 2.6 GHz in Turbo Mode. The 1.7 GHz Intel Core is an option for all models and can boost to 3.3 GHz when needed.
