Behind the scenes WWDC 2013: Haswell, Thunderbolt 2, 802.11 ac

One of the first Apple used a new processor from Intel, and the first in the industry announced the second generation Thunderbolt. And one of the first switched to the new Protocol 802.11. The new processor, in fact, was developed for the Coalition led UltraBook with Intel… Than the MacBook Air prevented Intel, I don’t know. This is a purely aesthetic rejection, since the concept UltraBook that tried to bring dozens of companies, was a copy of the MacBook Air, the only difference being that Air was running Windows, various Unices and OS X and none of the UltraBook running OS X, at least officially and without problems, didn’t work.

In addition, Apple was not going to use touch-screens in their laptops. To do it as well was nearly impossible, combining OS X and iOS hasn’t come yet, but Windows 8 has convinced the engineers of the correctness of this decision.

In June 2013, the confrontation between the Coalition (which produced hundreds of notebook models) and two models MacBook Air was two years old. To destroy and displace failed, only to press: in the market segment name MacBook Air have Air was 53%.

Among the other 47% had some very dangerous enemies, and the approach was new and even more dangerous. The hopes of the members of the Coalition on Windows 8 did not come true, now all with no less enthusiasm was waiting for Windows 8.1 – but the MacBook Air is the prospects were not too bright: their market share has steadily declined.

And then the leader of the Coalition made the Air a wonderful gift. On their own second anniversary.

Haswell find for UltraBook’s

In 2011, Intel has formulated the main objectives of the fourth generation of processors with the architecture Core: reducing energy consumption and converting built-in graphics processor a worthy competitor in discrete graphics chips.

Processor fourth generation, designed to offer great Air (“Air”) Dreams was so interesting to Apple, a week after the official release of the serial processor of the fourth generation (2 June 2013) he was in new MacBook Air models, sales of which started on 10 June 2013.

The new generation codenamed Haswell. It is not entirely clear what its called, here is a list of options:

— group of Islands in the Antarctic;
— the largest island in this chain of Islands;
— locality (village) in the County of Durham, Velikobritaniya;
— town (small town) in Colorado.

Processors Haswell as Ivy Bridge, manufactured on 22 nm technology, and superior past performance by 5-7 percent. But the direction of the main attack they had no equal. Especially modification with the letter “U” at the end of their designations.

In different chips UltraBook processors were integrated with a range of graphics, from Intel HD Graphics 4200 up to Intel Iris Graphics 5100 and Intel Iris Pro Graphics 5200.

Iris’s successfully competed with processors of the lower segment model series from NVIDIA and AMD. The media even started talking about the upcoming eviction of the giants of the market.

The processors used in Apple’s new MacBook Air was embedded with Intel HD Graphics 5000, surpassing Intel HD Graphics 4000 used in the previous MacBook Air graphics performance by about two times.

The fourth generation core processors were expensive (for everyone), but Apple could get from Intel “good prices”, especially since 53% of the target market for processors in this class had is the MacBook Air – all the other UltraBook’and, taken together, used about the same.

The standoff continued. Segment ultra-laptops were the only segment across the PC industry which continued to grow. In other tiny, light and moderately stupid tablets with appetite ate the natives.

Thunderbolt 2

In June 2013, Intel announced the second generation of the Thunderbolt interface, named austere and inappropriate fantasies Thunderbolt 2. Apple has been inscribed in the history of this transmission interface, becoming the first company in the world announced the use of Thunderbolt in the next generation Mac Pro, June 10, 2013.

According to analysts, there is a clear correlation between the prices of Intel processors and Apple’s willingness to use a new modification of Thunderbolt in Macs. Alas, to confirm or deny this statement I can’t – no data. The prices at which Apple is buying electronic components belong to the top secret information.

What, none of the parties owning the accurate information, not interested in the leak.

The second Thunderbolt is different from the first higher data rate (20 Gbps instead of 10 Gbps), support 6 devices per channel (instead of 5), and a more expensive chip “Falcon Ridge”.

On electronic level both Thunderbolt and Thunderbolt 2 are compatible. Paint the connectors was not necessary.

The support of 802.11 ac

802.11 ac Protocol wireless networks following the 802.11 n. First introduced in 2011, first appeared on sale in may 2012.

MacBook Air (probably due to the “Air” in the title) was the first Mac om using the new Protocol. Apple released a new Air and a new model AirPort Extreme 802.11 ac and AirPort Time Capsule 802.11 ac in June of 2013, when the Protocol was still in beta at this time.

Officially, 802.11 ac was published in December 2013.

For data transmission speeds of 802.11 ac is ten times superior to 802.11 n.
