MacBook Air 2013: who was the main?

13-inch MacBook Air 2013 is a perfectly balanced laptop with 12 hours of work in offline mode. 10 hours of viewing iTunes video on battery! It does not fit in the head, didn’t believe it, the parameters stated Apple did not try to challenge just lazy – but the claims were true… the Confrontation with UltraBook strained to the limit, experts expected that the MacBook Air would finally have the Retina display. In UltraBook with 1080p screens have long been almost the least decent, even had a 13-inch UltraBook’with a resolution of 2560×1440, but Apple came to the conclusion that their old usual display is still good enough, and didn’t change. Display MacBook Air did not support IPS.

But the MacBook Air was the first laptop with Haswell ULT, entered the market. Acer S7 in June 2013 passed the last test, the output of the other UltraBook’s on the new processor was planned for the end of summer or in the fall.

Experts, taught by bitter experience of recent years, in no hurry to award victory to any of the parties: while the specific model UltraBook’s won a MacBook Air on features, on set of parameters he was still ahead.

They guessed it: in terms of sales, he had no equal.

Why do I need an UltraBook?

Causes of ads Intel crusade against Apple in 2011, had no personal motive. No serious company in the world would venture such an expensive and troublesome project is not hoping to use it to earn a lot. In the same year Intel introduced to the public Haswell ULT processor designed for this class of portable devices.

The world has become increasingly mobile. Smartphones and tablets have conquered the market, but not all of computer users were ready to abandon the computer. In the proposal, the market formed a very delicious space: the demand for ultra-mobile devices are not inferior neither computers nor tablets. MacBook Air meet those needs.

Intel was winning in any case: both parties to buy its processors.

UltraBook’and came on the heels of the Apple, causing it to update the MacBook Air much more often than the company would prefer to do it in a relaxed atmosphere. The noise in the press about the ultra-compact laptops, has added fuel to the fire.

A vivid example of creative aggression.

This has not happened

This time in 11 – and 13-inch MacBook Air used the same modification processors. Intel Core i5 1.3 GHz (i5-4250U) and Intel Core i7 1.7 GHz (i7-4650U). Most likely, this strangeness was the reason, and guess what: first, the production of the new processors was just beginning, and quickly produce significant print runs of only two variants of the processor was real.

Secondly, Apple had some of the strongest negotiators in the industry, and have something to attract Intel. The volume of purchases. Just two modifications, the circulation of a few million per quarter. In the segment of ultra-compact laptops Apple had 56% of the market, its nearest rivals are hardly more than 20 percent – have something to bargain with.

For all i5-4250U worth USD 342 apiece, and i7-4650U – 454 USD. Apple would have died from the greed of selling the 11-inch Air with processor 342 of the dollar in just 999.

The experts compare $ 150 that Apple took for the replacement i5-4250U on the i7-4650U: the difference in the 112 dollar is godly. Well, Yes.

However, this is only assumption: data on prices and costs in 2013 are still classified as “top secret of special importance”.

Performance MacBook Air 2013 even inferior to the 2012 models. And only slightly superior to the model the year before.

802.11 ac

IEEE called 802.11 ac wireless Gigabit Ethernet’alternative, with a maximum of 1.6 GB/s was achieved only in ideal conditions. That is, never.

The actual speed of data transmission depended on many factors (speed of impact and distance between router and device, and obstacles such as walls and other interference), but still – from 802.11 ac expected a noticeable increase in throughput of Wi-Fi.

Tests WiFi-ability of the MacBook Air… disappointing. Data transfer rate was almost the same as in 802.11 n.

Having received such discouraging results, the experts found out why. Support for 802.11 ac was one of the most important innovations of Mac OS 10.8.4. The link worked steadily iron MacBook Air was able to transmit and receive data at the nominal speed of 802.11 ac, but the software is Mac OS 10.8.4, in particular support of the AFP, severely limiting speed.

I do not know as was the case with later versions of Mountain Lion, but in Maverick this problem was no more.

By the way, why the Protocol is called 802.11 ac? The letters were over. After 802.11 n, the IEEE has published dozens of protocols, with the following letter in the version designation of the Protocol. None of them became the new standard (some were used for special purposes) or 802.11 z, 802.11 aa no, no 802.11 ab.

PCIe 2

The transition to PCIe SSD was inevitable. In any case, the SATA controller connected to PCI Express. And that SATA has limited data transfer speed.

In devices designed exclusively to SSD, SSD controllers that work with PCIe without intermediaries eliminated this limitation, and their development was not particularly difficult.

Theoretically, the data transfer speed could be increased significantly. The reality was more modest: MacBook Air 2013, read and wrote one and a half times faster than the MacBook Air 2012 (according to testing the MacBook Air with the controller and NAND modules from Samsung).

Apple used memory from Samsung, Toshiba and possibly from other manufacturers, and that is installed in a particular Air not informed. Lottery?

Technical data

Online store the initial configurations 13-inch MacBook Air had two, with a SSD of 128 and 256 Gigabytes, 1099 and $ 1299. In both configurations, used Intel Core i5 1.3 GHz (i5-4250U), which for an extra $ 150 you could replace the Intel Core i7 1.7 GHz (i7-4650U).

In a configuration with SSD of 256 GB can be had for $ 300, to replace it with a SSD of 512 GB.

In both configurations, the installed 4 GB of RAM, which for $ 100 can be increased to 8 GB. Memory vpisalas in the motherboard of the computer, tightly: after purchase to replace it was only possible together with the cost.

The screen resolution – 1440h900 pixels.

The set of connectors is almost exactly the same as the 11-inch model. The difference is only one: slot for SDXC cards, which have 11-inch model was not.

The identifier of the model also differed: MacBookAir6,2.

Other technical data is almost exactly the same as 11-Domovoi model.
