Az Apple mar az A4 ota sajat maga tervezi a SoC-ot es ma mar a core-t is, NEM az A15-re epulnek a CPU-i, hanem teljesen custom tervezes, melyet az A6 eseten meg kezzel is vegeztek! Erre nagyon keves ceg kepes a vilagon, a Samsung peldaul meg sohasem csinalt ilyet...
Ajanlom az alabbi cikkeket, mivel nagyon le vagy maradva:
"The A6 is the first Apple SoC to use its own ARMv7 based processor design. The CPU core(s) aren't based on a vanilla A9 or A15 design from ARM IP, but instead are something of Apple's own creation." - http://www.anandtech.com/show/6292/iphone-5-a6-not-a15-custom-core
"Over the last week, more and more details of Apple's custom A6 processor design have come to light, including a custom armv7s-compatible core design and its triple-core GPU. Detailed analysis by Chipworks and iFixit have revealed that Apple's custom ARM core design appears to have been laid out by hand instead of by computer algorithms—a time-consuming process that can result in optimized high-frequency operation." - http://arstechnica.com/apple/2012/09/detailed-analysis-of-apple-a6-core-reveals-layout-done-by-hand/
