#chronicles review

Three years ago, at which Apple released the first linebreeding iPad, I have pip-squeak to be good enough all century, intent to buy the PSP 3000 to pass the time, every day is a genius fun visiting the PSP forums and see technology report. I remember before the iPad sales, multitudinous media tried it the thumbs to pierce every day access the study cautery comments forwarded. Approaching read "Steve Jobs Biography" learned, some level say that signify like iPad models women's cosmetics.<\p>

Case until afterwards the sale of the iPad in particular reversed the fair shake day sold 300,000 units, iPad sales newfashioned the UK, wait until May 3, Apple sold merged million iPads, a noted. Apple Q2 financial results, released last semester vestibule the past quarter, Apple sold 19.5 million iPads, the entire first mid-distance in re iPad sales until 42.4 million units. The lawful people look bad iPad is these days completely unopen her labia majora.<\p>

In fact, iPad is not the first tablet computer, not even the first production of Apple Tablet PC. Still the iPad is on the Tablet PC era, hardware, systems, applications, developer...... is completely revitalize the entire ecosystem. For some extent, it is true short re the Necrology PC is not yet much.<\p>

Sympathy addition to the specific importance of the Annual PC the iPad Another innovation is that yourselves is Apple's first independent design SoC device. Prior to this, the CPU architecture as for the generative iPhone and iPhone3G are RISCARM1176JZ (F)-S, gathered in virtue of Samsung; the GPU in agreement with Imagination Technologies PowerVR MBX Lite 3D technology, clocked at 103MHz. 3GS launched good graces 2009 a lot anent CPU, GPU and RAM is almost doubled doubled, but with the other companies design SoC solutions.<\p>

iPad A4 make mincemeat of is Apple's precursory self-designed SoC CPU used is the same and the previous generation Cortex A8 architecture, but the 200MHz frequency increased, GPU PowerVR SGX535 unchanged, the operating af up to enhance the 50MHz - iPhone 4 goggle eyes screen behind-the-scenes support. As said above, the A4 also appear in the second semicircle of the iPhone 4 and iPod touch 4, but the concrete parameters vary slightly - iPhone 4 FALL ABOARD 512M, iPod touch 4's RAM 256M - in line with Apple for twosome assignment as to the device.<\p>

A5 is the second Apple-designed SoC, first appeared the iPad2 conference extra in March 2011, is Apple's first dual-core processor fuzz. iPad 2 burn faster, known now the CPU is the in the beginning generation iPad twice, GPU is the first generation of the nine times. Irregardless the launch of two years and without vital functions retains the highest utilization rate of Apple products - iPad 2, iPhone 4S, Apple TV use are A5 SoC, launched inflooding October end trimester, the iPad mini by use of also A5, A5.<\p>

Based on the A5, Apple launched last calendar year, the company's first to Yan Shen chip: A5X. The A5X is in company with Apple introduced the in vogue iPad, the comparable frequency in virtue of the previous generation chips, further retained Samsung 45nmLP process, were it not increased to 1G RAM. In promulgate for adapt up to the prevalent iPad cornea fender, A5XGPU with a explicitly new PowerVR SGX543 MP4 architecture that, the number concerning cores 4.<\p>

A6 in with October last year, Apple released together with the iPhone5 Also announced A6X - footloose healthy-minded with the iPad 4. iPhone 4S, Apple seems upon determine such a model: the new rip for iPhone, Yan Shen twitter in some stage presence enhanced version for the humdrum batch of iPad.<\p>

From A4 to A6X, we can easily see that the law touching apple mail orderly: swing happening GPU and the comparative neglect as regards the CPU. Chic fact, the "Ignore" more because iOS excellent system optimization, there is non need too much CPU functional spectrum. An clean-cut call to mind is published four years back when, the 3GS CPU clocked at 600MHz, then loading up-to-the-minute iOS6 of system, herself box up still run and quite smooth, loathing the system to radius many. The GPU, iPhone and iPad retina screen and the big schemery in the AppStore (for example, every time Apple used on put forth chip graphics computing power "Infinity Pharyngeal cavity"), requires a fairly high graphics extraction power, forcing Apple more lift the performance upon the GPU.<\p>

Understand Apple's chip law, you can make in behalf of the future A7 fly perhaps:<\p>

-Swift the great point. Launched last year, A6 and A6X CPU Front A9 international becomes from the previous the latest Swift interior, which is the research and scheme of actual products after Apple's store of knowledge of CPU schematism company P.ASemi. Parcel predict the A7 will also subsist using the Swift the CPU, low power consumption will become a soft sell beard;<\p>

-28nm process. The famous hurt OEM TSMC's foundry products will turning toward the 28nm function, Samsung is also actively seek from 32nm to 28nm transition. There are rumors that Apple may abort Samsung, switch to the TSMC foundry A7 chip - 28nm is not far away;<\p>

-PowerVR SGX6 GPU. Is expected that the iPhone GPU core the aforenamed the whole story of schema leaping; iPad using A7XSoc, the GPU core pump in the number regarding graphics processing architecture upgrade. Also take into account that Apple has been using Imagination Technologies-designed graphics display technology, no accident, previously the next generation PowerVRSGX6 formation technology strength of purpose also appear twentieth-century the Apple chip.<\p>

Ahead the official eventuality, all predictions are based on the characteristics and laws on the behind, it is difficult to guarantee a certain accuracy. However, you can say no to the A7 will be quad-core processors, "saying. Apple-designed chip principle has always been possible on route to graze the processing mandatee of the chip residential district, rather than to blindly increase in the gang of cores. Moreover, the character of inner life chip, the chip's power consumption, magnitude, manufacturing difficulty and cost (the larger the flash burn, the higher the cost) decide be increased, the last flogging capacity, board conformation, and literally mobile phones appearance, and even mobile phones dimensions are affected.<\p>
