Taiwan is currently not on sale, but we have to start from Hong Kong with a Haswell processor, MacBook Air 11 Mid 2013.

In the last WWDC, Apple’s Mac Pro and the MacBook Air has been updated, and we take a look at a new generation of MacBook Air processor What are the characteristics of it.

In the MacBook Air Mid 2013 before the release, Retina Display is one of the options many people expected, but in the post that moment, the new MacBook Air update only the processor, some people will inevitably feel a little lost heart.

Mid 2013 and Mid 2012 in the appearance section and there is no difference, in addition to the I / O, resolution, keyboard, touchpad also are exactly the same, without any change.

There is a change parts, the first is the processor, and the second is the processor heat sink module, and the third is a PCIe SSD, the last is the 802.11ac wireless network module.

Processor section, using a fourth-generation Intel Core processors, Apple chose Intel HD Graphics 5000 the Core i5-4250U and Core i7-4650U two processors, which requires obtained through paid upgrade.

Clock regard, Core i5-4250U than 1.6GHz Core i5-4200U, running clock is 1.3GHz, but after Turbo Boost clock and Core i5-4200U same as 2.6GHz.

Why would such a product, perhaps with the TDP has a significant relationship.

1.6GHz Intel HD Graphics 4400 with the Core i5-4200U, officially marking the largest part of the TDP 15W; clocked at 1.3GHz, with Intel HD Graphics 5000 The Core i5-4250U, Maximum TDP and clock higher Core i5-4200U same as 15W. We believe that Intel’s practices by lowering the clock, so that the higher GPU processor remains in the same TDP, the main clock is present on the impact of multi-core processor architecture is not over far greater.

The same thing happens also part of the Core i7, Core i7-4650U clocked at 1.7GHz, while the Core i7-4600U clock and up to 2.1GHz, the maximum TPD maintained at 15W.

Radiator module, then, a new generation of U-series and Y series processor SoC architecture, the processor looks bigger teeth than in the past, but it contains a CPU + GPU (the larger part) and PCH (general said Southbridge), so the cooling section also need to do some changes.

Answer #1

This generation of MacBook Air with a new PCIe SSD, the controller portion has two versions. Our hands 11 inches SanDisk’s Marvell 88SS9183, another version is a 13-inch Samsung S4LN053X01.

Than the current PCIe SSD mSATA SSD provides faster read and write speeds, I believe that the new generation of MacBook Pro will abandon mSATA specification change using the new PCIe specifications.

Ultrabook, it has already imported M.2 specification, our Sony VAIO Pro 11 tests can be found. This will be the next generation of storage M.2 new trend, it can also compatible with mSATA or PCIe, Intel will start from the Z97 chip start importing.

Although Apple’s PCIe SSD M.2 similar, but identified two different specifications.

MacBook Air Mid 2013 panel does not replace, maintain a 11-inch 1366 x 768, while the 13-inch is 1440 x 900. Air, Pro Series panel performance did not come well, a waste of Mac OS X’s advantage, and this generation is not updated to the Retina Display, including myself feel a little disappointed.


However, to improve the resolution after the endurance will be diminished, perhaps because of this reason and let Apple did not let Air updated to Retina one of the reasons it.

Endurance because Intel Haswell processor has improved, official data is nine hours, but we got through a power calculation about 9 hours 44 minutes or so of data. Users outside for a long time, this type of endurance required almost enough to one day, not to mention the MacBook Air does not actually heavy transformer.


Then look at what point in time for Apple MacBook Pro 13 and 15 to update the processor, rather than U-series processor MacBook Air, using a standard voltage processor MacBook Pro line more attractive to my attention.


In addition, until Mac OS X 10.9, which is the code Mavericks after the release of the next version of the operating system, let us look at this comparison MacBook Air 11 Mid 2013’s performance in the two versions of the operating system how much difference.
