Employees of Chipworks continue their hard work on the study of the system-on-chip (SoC) Apple A7 , and were able to get a lot more interesting information. In particular, it is produced by Samsung with 28 nm process technology using HKMG (High-K Metal Gate). Moreover, experts have found in him a 4-core GPU PowerVR G6430. This is the first commercial use of the sixth-generation PowerVR graphics accelerator, although in the case of Apple this fact is not surprising, as the company owns part of the shares of Imagination Technologies.
In addition, the U.S. company for the first time in the industry has used a mobile device 64 biny processor and the first to launch a 64-bit mobile OS. Apple entered the mobile market peak of progress thanks to its special relationship with ARM, provide partners with a unique license. It gives permission to create modified at will cores ARM, including the use of the latest developments in this field. In this case, Apple has used the architecture ARMv8 Cyclone, which will be available to other players of the market no earlier than six months. That is, in the near future does not shine Samsung to release its own 64-bit processor-based SoC ARM, it does not have a license.
We add that the GPU in the iPhone 5s became the first mobile video accelerator that supports not only OpenGL 3.0, DirectX 10 but. By the way, testing Anandtech has demonstrated an impressive superiority of 2-core Apple A7 over the 4-core competitors, and even over the Samsung Octa (4 +4 cores). In addition, the 4-core PowerVR in the iPhone 5s was the first mobile GPU, gone beyond 30 frames per second in the test GLBenchmark T-Rex HD in native resolution.
