Apple A7 chip is likely an evolved A6 rather than a brand new design. Apple has designed the A7 as a high-end ARM chip which was launched in September 2013 alongside the iPhone 5S. The A7 chip can also be found in the iPad Air. As incorporated in the iPhone 5s, Apple’s new A7 chip is the world’s first 64-bit ARM-based chip but not Apple’s first quad-core chip and is a successor to the A6.
Instead, the A7 is dual-core proceessor among a list of Android competitors boasting of 64-bit quad-core processors. Benchmark scores on Apple’s new iPhone 5S, reveals that, it is the dopest smartphone silicon ever made. It’s performance outsmarts other devices crushing every other smartphone out there on both computational power and graphics. But looking at common specs like its number of cores and clock speed for the hardware, you’d never know it.
Process Technology (nm)
The chip is manufactured in a 28nm HKMG (High-K Metal Gate) process technology by Samsung and according to estimated output it has a maximum power consumption of less than 2 – 3W. In the iPad Air, the SoC should have a slightly higher TDP due to higher clock rates and less throttling.
Apple A7 Processor
Cyclone is the successor to the Swift architecture as found in the previous Apple A6 and A6X processors, being a dual-core processor allows Apple to save power, while a shift to 64-bit allows Apple to improve performance, especially for apps programmed to take advantage of it.
According to Anandtech, the dual-core A7 ranked as one of the fastest system-on-a-chip after tested under SunSpider, even outpacing Qualcomm’s Snapdragon 800 and ARM’s Cortex A15.
The two CPU cores in the A7’s iPhone 5s are clocked at 1.3 GHz and in the iPad Air at 1.4 GHz respectively. In combination with many other improvements like a larger 256KB L1 caches and other optimizations, Apple has increased the performance per clock by about 50 percent.
Apple A7 Graphics
The A7 chip integrates a PowerVR Series 6 (Rogue) G6430 GPU with four clusters. The G6430 offers twice the computing ability of the SGX543MP3 in the Apple A6 and supports OpenGL ES 3.0 for the first time.
The exact clock can be measured around 400 MHz range resulting in more than 100 GFLOPS.
In the iPad Air, the GPU is clocked slightly higher at about 450 MHz. The iPhone 5s graphics performance is spectacular as it produces a speed of up to 37-frames per second, more than twice the iPhone 5’s 14 fps and the next-best US smartphone, the Motorola Moto X, which clocks in at 25 fps. One can say, the iPhone 5S’s graphics powers are ready for the craziest gaming experience that’ll be coming out in the years to come.
Over at AnTuTu, specifically on the version 5, the chip reaches a max points of 37,527.
