See this title might have felt a little extreme, but this is true in recent years relative to the Apple iPad using a series of enhanced version, other mobile processor performance does lag a lot. How did the Apple on this crazy path? Today we have a look at the iPad's crazy stack of course:
The New iPad (third generation iPad, iPad 3,A5X processor)
The New Madden A5X iPad introduced at that time, also the first level gives iPad Retina screen, resolution up to 2048*1536, the resolution was in force up to now the iPad and iPad Air2 mini4, can be said to be the Times Herald.
Apple A5X processors (quad-core dual-core A9+ SGX544)
And The New iPad is first paragraph in SoC Shang with "x" suffix of products, Apple for it specifically introduced has A5X chip, it is a star double nuclear Cortex-A9 1.0GHz of processor, GPU is SGX543MP4 250MHz, used Samsung of 45nm process manufacturing, although now view such of parameter does not how, but at this absolute said have Shang is Monster level performance, GPU performance sharply leading at of competing products Tegra 3. While A5X memory bandwidth 128bit, LPDDR2 32bit 800MHz uses four channels, bandwidth up to 12.8GB/s, which at the time was also a leading data. But even the most heinous A5X,The New iPad resolution is too high, causing it to flow is poor, but the iPad as a Retina screen, absolute called a classic product.

CPU performance, because Apple A5X period has not started using their own CPU core, core SoC performance and other Cortex-A9 and not too big gap.

GPU performance of SGX543MP4 at that time showed a very high-handed of absolute performance, is a ride in the Offscreen test dust, but due to the high resolution, bright screen results as worse than iPad 2. Does in the actual experience, The New iPad in terms of fluency rather poor, perhaps for this reason, it was soon replaced by iPad with Retina Display.
IPad with Retina Display (fourth generation of iPad, iPad 4,A6X processor)
Named ridicule of Apple in such a mess in the first place, is The New iPad, one is iPad with Retina Display, really make people scratching their heads. IPad with Retina Display and The New iPad has maintained the same figure, now they are too heavy and too bulky. Maintain a 9.7-inch screen Retina, but runs faster on the iPad with Retina Display a lot, that's because it carries a new monster--A6X.
Apple A6X processors (quad-core dual-core Swift+ SGX554)
A6X specifications do not appear to be a strong, is still "2+4" (quad-core dual-core CPU and GPU) of the structure, but Apple's frenzied independently developed CPU took to the road of no return, Swift turned Herald March Apple CPU single-core performance. Although the frequency is "only" 1.4GHz, single-core performance ahead of processors using the Android camp in the same period. GPU is MP4, however the core into a powerful lot of PowerVR SGX554 theoretical performance is twice times the A5X. In addition, A6X memory bandwidth up to 17GB/s, using the Samsung manufactured on 32nm process technology.
IPad 4 CPU performance comparison (Sunspider 0.9.1)
IPad 4 CPU performance comparison (Octane Benchmark v1)
To A6X on iPad with Retina Display, Apple finally introduced its own CPU core, also begins here, Apple's CPU power gradually faster than Android. CPU on a single core performance due to Nexus 10 carrying Cortex-A15 and powered by Atom RAZR I appeared, A6X CPU performance doesn't have an overwhelming advantage, but relative to the mainstream Cortex-A9, Krait framework, Apple's processor performance is much more powerful.
IPad 4 GPU performance comparison (GLBenchmark 2.5 Egypt HD on screen)

GPU, instead of The New weakness of the iPad, iPad with Retina Display specifications is used SGX554MP4 much exaggerated, memory bandwidth is increased to 17.1GB/s, performance improved significantly, absolute performance GPU is almost twice times bigger than previous generations. Fluency and game performance will be much better. On tests of Offscreen, iPad to stay ahead of second-place Nexus 10 lots, screen tests and much lower resolution of Nexus 4 (freezer version) and iPhone 5 in the same level.
IPad Air 2 (sixth-generation iPad,A8X processor)
If is the iPad's 9.7-inch iPad as the main line, the 2014 iPad released Air 2 is the sixth generation of iPad. Careful friends may find us to ignore the iPad Air of fifth generation, it is because it is only in recent years did not bring the x suffix processor 9.7-inch iPad. IPad Air of A7 and the iPhone doesn't make too much difference on the 5s, just high CPU frequency 100MHz, so we ignored it. IPad A8X on Air 2, size really exaggerated, CPU is actually three Typhoon, frequency of 1.5GHz, although Typhoon frequency relative to the Cyclone did not substantially enhance A7, but the frequency increase to 1.5GHz, added a core, A8X performance relative to the A7 have significantly improved. In addition, 20nm A8X using TSMC technology.
Apple A8X processor (triple-core Typhoon+ eight-core PVR 6XT)
And GPU,A8X to Apple's traditional strengths is confident to join 8 core PowerVR GXA6850, even broke through the public version of the PowerVR 6XT series of up to six-core design, can be said to be specially tailored for Apple's GPU. And the GPU performance is no doubt, it has 256 ALU units, just ahead of last year is far and Tegra Kepler on the K1 (192 CUDA cores), even to today's standards, its performance is still ranked in the forefront. A8X has increased dramatically in the memory, the memory bandwidth has soared to 25.6GB/s, and let Apple be moved tiling 2G.

As for CPU performance, in the iPad era of Air 2, Apple can't do the world, because NVIDIA's Tegra K1 (Duo Denver version) also has a very impressive single-core performance, NVIDIA Denver architecture and Apple a chip route is similar, although only two core and single core performance but very powerful. Denver used the ARMv8 instructions, launch width up to 7, with a Dynamic Code Optimization (dynamic code optimization), is a homegrown core of 64-bit processors. Multi-core performance, three nuclear has gone beyond the iPad Air 2 Android phones and eight-core processors.

GPU, iPad Air 2 a very strong performance, but did not reach the point of ruling-class, are only slightly compared with Nexus 9 wins, of course, and cell phone, iPad Air 2 still has a huge advantage.
IPad Pro (A9X processor)
IPad the iPad Pro is not a traditional, you can look upon it as an Apple product development "side quests", in relation to its price, use and determines its sales are not particularly good for its size, but this does not affect the Apple in its continued piling up hardware. IPad Pro uses the most powerful mobile processor A9X, even claims its CPU performance comparable to desktop products, like A9, using the dual-core core Twister, but increase CPU clock speed to 2.26GHz, making it straight up to a whole new level of performance. Although A8X trinuclear "shrunk" to dual-core and single core performance but too powerful, multi-core performance goes well beyond the A8X even eight core Android products. A9X use TSMC and some iPhone 6s 16nm FinFET technology. Another prominent feature is the iPad Pro uses the unprecedented 4G memory, such specifications into Android devices are considered as the top, had the highest 2G of absolute iOS device called a "massive". A9X upgrades to the standard of LPDDR4, 128bit bit wide memory bandwidth to a terrorist 51.2GB/s, meet iPad Pro 2048x2732 "3K" resolution, rather easily.
Apple A9X processor (dual-core nuclear PVR 7XT Twister+ 12)
GPU in Apple's certainly not neglect, is brought about by the PowerVR graphics processor Series7XT, but it's not 8 core GT7800, is not the highest end 16 core GT7900 (normal mobile devices unable to control the power consumption), but once again for Apple 12 custom GPU nuclear, it has 384 ALU units. Such abnormal parameters, no doubt, of course, A9X graphics performance is almost dominate the mobile phone twice times the A9, and Tegra on the X1 of the King before the amplifier down Maxwell (256 CUDA cores) architecture GPU.

From CPU performance, the iPad Pro (A9X) is definitely rolling stage performance, easily put down Android family, but also significantly ahead of Apple's own iPhone 6s Plus (A9). Although only dual-core, iPad Pro Geekbench nuclear test just ahead of Android in the first echelon of Galaxy Note5 (Exynos 7420), to achieve a "2-8" feat.
IPad Pro GPU performance comparison (GFXBench screen 1080P)
Comparing GPU is no doubt, Android only has "capability" Legion of NVIDIA in the A9X vulnerable before, let alone mainstream Exynos 7420, Xiao long stream of 810. With most close to the remains of their iPhone iPad Pro 6s Plus, for this generation of graphics performance, whether it is a phone or a Tablet, Apple can be said to be unparalleled.
Summary MCM iPhone 6 Plus
Starting from The New iPad A5X, Apple just to show its costs of hardware, Apple's a series processors with strong performance once again conquered the players, which we are in the "Apple does not spell hardware" image is completely incompatible. Particularly with regard to GPU, Imagination to give Apple a strong support, Apple is again and again suppressed in NVIDIA graphics processor for the Bank. Latest A9X, Super single-core performance, still dominant GPU performance and exaggerated memory bandwidth are staggering, but the iPad Pro position is slightly more exotic, we still expect it to be "devolved" to iPad Air iPad mini series.
Finally attach this SoC specifications summary:
Yes, this article does is brag about how awesome Apple has X,iPad Pro A9X is totally worthy of this picture:
