Over the years, many people think that Apple "not parameter", not the pursuit of the hardware configuration, and Apple has been on a SoC performance breakthroughs. In the recently released iPhone 6/iPhone used on the 6 Plus the new A8 processor, although it continues to be dual-core architecture, but has greatly improved performance than the previous generation, the apples are piled up to the A8 "material"? solar motion light
CPU
We know that Apple first introduced the 64-bit architecture on the A7, new processor brings horror of a single core performance, although the frequency is 1.3GHz, but performance is to compare Android phones 2.0GHz processor. The A8, Apple announced a 25% increase in the CPU.
And before the release of the Twitter user @ Swiss remember iPhone 6 "Twitter Conference" has been released on the iPhone 6 configuration information and run shots, iPhone 6 internal code iPhone7,2,CPU frequency 1.38GHz, memory is still 1G.
Judging from run, iPhone iPhone 5S-6 upgrade is also more in line with Apple's official propaganda, using 32-bit Android Galaxy 4.4.4 system Note 4 still has a lot of advantages. Judging from this score, almost certainly A8 continues to be dual-core architecture, using Cyclone schema version could be improved. Judging from the frequency, iPhone 6 only better than iPhone 5S increased the frequency of 100MHz,8% Ascension brings 25% performance increases, the new framework brings more RF performance.
GPU
Apple every generation of GPU for the new SoC will lead to very substantial performance improvements, Apple claims to have GPU performance 50% (generally is a 1 time in the past). Generation of A7 is to go on Imagination PowerVR G6430 graphics performance is the first echelon in the past year.
Noted in Apple's developer documentation, A8 support ASTC technology, this is PowerVR Series6XT feature, but according to enhance performance, Apple is likely to PowerVR GX6650 (of course it is also possible to use high-frequency version of the PowerVR GX6450) into the A8, which is pretty crazy.
GX6650 is the most powerful GPU active Imagination, which belongs to the PowerVR Series6XT series, with a total of 192 core FP32 ALUs (in accordance with domestic manufacturers propaganda, which can be seen as the "192 nuclear" GPU). Such specifications already and now mobile GPU GeForce Tegra K1, 300MHz, Tegra K1 and GX6650 can be 115.2GFLOPS FP32 floating point computing power, quite powerful. Actually we're second in the model number is 6, it means it has 6 USC, in fact, should be viewed as a "six-core", in the same way, A7 G6430 should see results on a quad-core, MT6595 G6200 should be on as a duo.
In addition, the PowerVR Series6XT one more core than PowerVR Series6 both FP16 ALU element, a core 2 FP32 ALU,4 in-FP16 ALU
PowerVR Series6 is 2 FP32 ALU,2 FP16 ALU
After the A8 was determined using the PowerVR Series6XT, controversial is that it uses GX6450 or GX6650.
Although the A8 used advanced process of 20nm, but the core area has reached 89mm^2, while still using the dual-core of the A8 in the area to accommodate the next GX6650 is also possible. Of course, GX6650 is not fuel-efficient lights, Apple may want to consider power consumption problem on the A8 into a high-frequency GX6450. Graphics performance on the A8, we announced on September 19, the real test for everyone.
