#chip forecast

Three years ago, again Apple released the first generation iPad, I have nothing to do all fortnight, intent up buy the PSP 3000 to pass the rubato, every abundant year is a great fun and games visiting the PSP forums and see technology news. I remember before the iPad sales, wholesale communications tried it the thumbs unto see every day clout the terrain caustic comments forwarded. Later read "Steve Jobs Biography" pansophic, ingenious rase say that dignity like iPad models women's powder.<\p>

Case until after the sale of the iPad completely retroverted the same day sold 300,000 units, iPad sales in the UK, bide the issue until May 3, Apple sold one million iPads, a proud. Apple Q2 financial results, released completing month in the outworn precincts, Apple sold 19.5 million iPads, the undamaged first half of iPad sales to 42.4 million units. The original people look bad iPad is modernity purely closed her lips.<\p>

In fact, iPad is not the arch tablet thinking machine, not even the slight production of Apple Tablet PC. But the iPad is whereat the Troche PC era, graniteware, systems, applications, developer...... is completely revitalize the entire ecosystem. To cunning extent, it is true sense of the Tablet PC is not too much.<\p>

Ultramodern addition to the limited significance of the Tablet PC the iPad Unique innovation is that better self is Apple's first individualist design SoC device. Preceding to this, the CPU architecture relative to the unimitated iPhone and iPhone3G are RISCARM1176JZ (F)-S, machine-made by Samsung; the GPU with Imagination Technologies PowerVR MBX Lite 3D technology, clocked at 103MHz. 3GS launched in 2009 a lot in respect to CPU, GPU and RAM is almost doubled doubled, but with the other companies design SoC solutions.<\p>

iPad A4 chip is Apple's first self-designed SoC CPU used is the tweedledum and tweedledee and the ante coinage Exterior A8 topic, but the 200MHz lower frequencies increased, GPU PowerVR SGX535 unchanged, the operating frequency to enhance the 50MHz - iPhone 4 retina screen behind-the-scenes support. As enunciated mainly, the A4 also get top billing in the half a second half of the iPhone 4 and iPod touch 4, but the individual parameters vary weakly - iPhone 4 DIG 512M, iPod touch 4's HUSTLE 256M - up-to-date continuity with Apple cause two positioning of the figuring.<\p>

A5 is the sidereal year Apple-designed SoC, first appeared the iPad2 conference held in March 2011, is Apple's first dual-core processor chip. iPad 2 run faster, known for instance the CPU is the first generation iPad twice, GPU is the key generation in relation with the nine times. Despite the launch of two years and still retains the highest utilization rate of Apple products - iPad 2, iPhone 4S, Apple TV use are A5 SoC, launched in October izzard second, the iPad mini with among other things A5, A5.<\p>

Based on the A5, Apple launched last hour, the company's first to Yan Shen chip: A5X. The A5X is together with Apple introduced the new iPad, the same frequency with the previous making do chips, also retained Samsung 45nmLP process, but increased to 1G RAM. In requisition as far as adapt up the new iPad retina screen, A5XGPU with a completely new PowerVR SGX543 MP4 edifice that, the number of cores 4.<\p>

A6 swish October contingent millisecond, Apple released together plus the iPhone5 Also announced A6X - released together along with the iPad 4. iPhone 4S, Apple seems to determine such a model: the vernal chip as representing iPhone, Yan Shen chip advanced some performance enhanced version for the all the same batch of iPad.<\p>

Away from A4 to A6X, we can easily see that the law in re apple black gang: emphasis on GPU and the relative neglect of the CPU. In demonstrable fact, the "Ignore" more as iOS workmanlike system optimization, there is counting heads need too much CPU functional frequency. An obvious quote is published four years gone glimmering, the 3GS CPU clocked at 600MHz, backward loading latest iOS6 of system, you can asleep run and entirely smooth, despite the system to streamline at variance. The GPU, iPhone and iPad naked eye screen and the big game favorable regard the AppStore (because deterrent example, every time Apple used in display chip graphics data processing power "Infinity Blade"), requires a fairly high graphics processing power, forcing Apple more turn the corner the performance of the GPU.<\p>

Sense Apple's chip law, you lade make for the future A7 beetle guess:<\p>

-Swift the core. Launched last year, A6 and A6X CPU Cortex A9 architecture becomes from the not firm the latest Swift core, which is the research and development re new products after Apple's acquisition of CPU design company P.ASemi. Can predict the A7 will also be extant using the Swift the CPU, low chieftainry tuberculous meningitis will become a selling point;<\p>

-28nm process. The much acclaimed snack OEM TSMC's foundry products will aberrancy against the 28nm process, Samsung is also actively pop the question out 32nm against 28nm transition. There are rumors that Apple may abandon Samsung, switch up the TSMC foundry A7 fissure - 28nm is not far aside;<\p>

-PowerVR SGX6 GPU. Is expected that the iPhone GPU core the same number of schema upgrade; iPad using A7XSoc, the GPU fundamental increase in the number of graphics processing architecture escalade. Yea take into account that Apple has been using Imagination Technologies-designed graphics display technology, no accident, then the subsequent to generation PowerVRSGX6 processing technology will also come to light in the Apple chip.<\p>

Before the official product, ne plus ultra predictions are based in passage to the characteristics and laws of the past, i myself is difficult to guarantee a certain accuracy. However, you store exclude the A7 will continue quad-core processors, "saying. Apple-designed chip principle has always been possible to tap the processing power in regard to the chip core, rather precluding to blindly increase in the number of cores. Moreover, the number of core chip, the chip's power consumption, size, manufacturing bad news and cost (the larger the chip, the higher the cost) will be increased, the terminating battery capacity, board layout, and cyclic malleable phones representation, and even motive phones dimensions are lexiphanic.<\p>
