First tests of MacBook Air 2015
MacBook Air 2015 We have begun to test the MacBook Air 2015 versions 11 and 13 ” . These machines having arrived only today we started with some raw performance tests. The families 11 “and 13″ always understand two basic models and we bought those placed in high-end, without taking option.
Leaving aside their screen sizes, these two machines multiply commonalities, including Core i5 “Broadwell” 1.6 GHz, 4 GB RAM, 256 GB SSD and Intel HD graphics chip Graphics 6000 (for other changes, see the previous article: MacBook Air 2015, more powerful and more expensive ).
On paper, however, the MacBook Air 13 “was announced by Phil Schiller as having an SSD is up to two times faster than the 13″ Spring 2014. And it’s true! In contrast, the 11 “is sticking to its SSD last year. A word about their suppliers, we have the Samsung 13″ was already the case last year. SanDisk and the 11 “as the year last year also and even before . No Toshiba on the horizon. In summary, go to 13 “if you absolutely want the Samsung and best performance SSD.
We will test the following two configurations, which experienced a great surge in prices at the time of renewal:
11 “Core i5 1.6 GHz (2.7 GHz Turbo Boost), 4GB RAM, 256GB SSD and an Intel HD Graphics 6000: € 1,249 (instead of € 1,099 in 2014).
13 “Core i5 1.6 GHz (2.7 GHz Turbo Boost), 4GB RAM, 256GB SSD and an Intel HD Graphics 6000: € 1,349 (€ 1,199 in 2014).
Processors
We tested for the moment these machines with Cinebench R15. In the 2015 family processors and graphics chip are identical, the scores are too. On this aspect, customers of 11 “are served as well as those of 13″.
Last year, the MacBook Air had a Core i5 “Haswell” to 1.4 GHz. Facing them, Cinebench found the Core i5 1.6 GHz 9.5 to 11% faster. The OpenGL test that will test the graphics chip shows, as promised by Intel, a greater gain between 35 and 44% on the previous HD Graphics 5000.
SSD performance
Our 13 “is equipped with a 256 GB SSD from Samsung and 11″ of SanDisk. The following tables provide the means for file copies of small and large sizes.
Small files
Sequential read, the SSD of 13 “is almost twice as fast as the 11″. For example, you get 680 MB / s average read against 369 MB / s. The gap is widening more during random read / write tests. And knowing that last year our 11 “and 13″ gave almost the same scores, the comparison is as flattering from one year to the other between the MacBook Air 13 “.
Is it so far 11 “still manages to do better than its predecessor? Yes if it is based on our previous tests , but this improvement is far from hair-raising, we gain a few dozen megabytes / s.
Large files
The competition is folded here as the benefit Samsung SSD that displays four-digit scores, as rather sees the MacBook Pro, iMac or Mac Pro. In reading and writing is very briskly than 1000 MB / s, while the 11 “is around 700 and 500 MB / s.
In summary, since 2013, the SSD 11 “accelerate their trot while those of 13″ forward at a gallop. This is not to say that these 11 “are sluggish – we are still on the SSD – but Apple have improved its range 13″ as its range 11 “which has just arrive MacBook in his rearview mirror (read A small MacBook announcing disruptions ).
Other tests will follow, notably on autonomy. What we see currently is that between a graphics chip and faster SSD is much more than last year, the MacBook Air 13 “” looks particularly interesting despite the lack of Retina display. To be confirmed …
