Preview at WWDC likely in June, followed by September launch.
New MacBook Pro and Air Benchmarks Comparable to Mid-2014 Models
The latest 11" MacBook Air, with an Intel Core i5 processor clocked at 1.6GHz, also performed comparably to its predecessor in Geekbench benchmarks, with its single-core score of 2753 and multi-core score of 5486 marginally higher than the mid-2014 model's scores of 2430 and 5291 respectively. Meanwhile, the new 13" MacBook Air had modestly lower scores, although more benchmarks will need to be averaged before results are conclusive.
John Poole of Primate Labs, the makers of Geekbench, claims that the latest MacBook Pro and Air may see slight performance improvements after OS X Yosemite gets through first-boot housekeeping, so further benchmarks results will be needed for those models as well to determine accurate performance. Nevertheless, it is clear that this year's refreshed MacBooks deliver only negligible improvements over the year-ago models.
The results are largely unsurprising given Intel's focus on improving battery life versus performance with its latest Broadwell processors. The new MacBook Air and Pro lineups also have faster graphics and flash storage, two areas where improvements should be more noticeable over last year's models. The refreshed 13" Retina MacBook Pro in particular is up to 40% faster than the previous model with Intel Iris graphics.
Apple refreshed the MacBook Air lineup yesterday with Intel Broadwell processors, Thunderbolt 2 and Intel HD Graphics 6000. It also refreshed the 13" MacBook Pro with similar improvements, including Intel Broadwell processors, Intel HD Graphics 6100 and all-day battery life. The latest MacBook Pros also gained a trackpad with built-in Force Touch technology that detects a small tap versus a deep press and performs a different action accordingly.
