Very confused, in some websites, they have this line:
iPhone 5s CPU: Apple A7
other websites saying that:
iPhone 5s System-on-chip: Apple 7 CPU: 1.3 GHz 64bit dual core
other sources saying that
iPhone 5s System-on-chip: Apple 7 CPU: 1.3 GHz 64bit dual core Apple 7
in Wiki, it said:
The Apple A7 is a 64-bit system on a chip (SoC) designed by Apple Inc.
It first appeared in the iPhone 5S, which was introduced on September
10, 2013. Apple states that it is up to twice as fast and has up to
twice the graphics power compared to its predecessor, the Apple
A6. While not the first 64-bit ARM CPU, it is the first to
ship in a consumer smartphone or tablet computer.
There are 2 sentences:
The Apple A7 is a 64-bit system on a chip (SoC)
&
While not the first 64-bit ARM CPU
Wiki also said The A7 features an Apple-designed 64-bit 1.3–1.4 GHz ARMv8-A dual-core CPU, called Cyclone
So System on chip is also CPU? very confused
Then other source compares System on chip and CPU, they said "CPU will not work without other around components" & "System on chip is the combination of CPU & other components into a single chip."
Best Answer
The A7 as the A4, A5 and the A6 are Systems on a chip.
On the chip there is the CPU (an ARMv8), the GPU (a Power VR), the IO controllers and the RAM.
