If you're thinking of buying the new MacBook Air I would strongly recommend the i7 processor. Multi-core performance on the i5 chip increased 7 percent, while multi-core performance for the i7 model increased 14 percent.ĭue to the more meaningful jump in multi-core performance between the 2.2GHz Core i7 chip and the 1.6GHz Core i5 chip, Poole recommends that MacBook Air buyers go for the processor upgrade. On the new MacBook Air, both the default 1.6 GHz Core i5 chip and the 2.2 GHz Core i7 chip available as an upgrade performed somewhat better than their predecessors on the 32-bit single-core test, but there were more significant gains in the multi-core test for the higher-end processors.Īccording to the new averages, single-core performance increased 6 percent from Haswell to Broadwell. The new data indicate that performance improvements may indeed be somewhat better than initially thought, though still relatively moderate. Earlier this week, we shared some Geekbench benchmarks for the Broadwell processors in the new 13-inch Retina MacBook Pro and the new 13-inch MacBook Air, which pointed towards speeds that were comparable to mid-2014 models.Īt the time, we noted the results might shift once more data came in and the machines got past their initial housekeeping tasks, and Primate Labs' John Poole has now shared additional benchmarks for all stock versions of the new machines.
