Early benchmarks are beginning to appear for Apple's 2014 MacBook Airs
. Primate Labs' Geekbench indicates that the base 11- and 13-inch systems, each powered by a 1.4GHz Core i5-4260U, score 2,532 under single-core tests, and 4,781 when using both cores. By contrast, the 1.3GHz Core i5-4250U in 2013 Airs managed scores up to 2,461 and 4,615, respectively.
The differences between 2013 and 2014 models are so marginal, notes
Primate Labs founder John Poole, that Apple didn't even update its model identifier. People wanting faster performance can upgrade to a 1.7GHz Core i7, but that costs $150 extra.
Rumors have claimed that Apple is working on a more dramatic update for later this year, in the form of a 12-inch Retina model. The computer will also allegedly adopt a fanless design and a clickless trackpad, and more controversially, fewer inputs and outputs.
