Besides that, the new generation MacBook Air with Haswell processors offering significantly higher battery life and higher performance, there are reports that Apple apparently he also updated the storage that hides in the device. By the way, all generations ultrathin MacBookov Air they had Flash memory, which is several times more powerful than existing average HDD hard disks. As it turns out, the new Flash memory is up to 9 times faster than a standard hard disk with a speed of 5400 revolutions per minute.
At the same time, this new unit is up to 45% faster compared to the previous generation, thanks to which the data writing speed easily reaches the limit of 800MB/s. Behind this positive change is the fact that sa Apple decided to use the PCIe 2.0 interface instead of the SATA standard, which is found in the vast majority of today's desktop computers and laptops. The PCIe 2.0 interface is capable of transferring data at a speed of up to 1GB/s, so we can consider the interface change revolutionary. At the same time, the AnandTech server found that the production of Flash remembers pre MacBook Air was taken care of by Samsung, but it is speculated that SanDisk is also in charge of part of the production.
At the same time, this new unit is up to 45% faster compared to the previous generation, thanks to which it reaches a writing speed of up to 800MB/s. Behind this is also the fact that sa Apple decided on a new one MacBook Air to use PCIe storage, which until now was only very rarely found in common consumer computers. As the server AnandTech found out, the production of Flash remembers pre MacBook Air was taken care of by Samsung, but part of the production is reportedly also covered by SanDisk.
Despite the fact that Apple decided to use an Intel Core i5-4250U processor with a lower frequency on paper, according to the tests, the performance of the device is maintained at almost the same level as its predecessor, so the frequency does not have a big impact on the performance of the device. Compared to the previous generation, there was a reduction in performance by 5%, which is mainly due to the combination maximal Turbo Boost frequency, cooling and base frequency. In the case of the integrated graphics chip, the frequency of the graphics core has been reduced from 350 to 200MHz, while inside we find an Intel HD 5000 chip.
Another big change was the operating memory. While Macs have used DDR3L memory until now, the latest is already coming with a new type of memory, LPDDR3, which is adapted for Haswell processors. LPDDR3 differs from the standard version mainly by lower energy consumption, which helped to increase battery life to 9 and 12 hours.
