[b]PS4 v Xbox One - CPU[/b]
At the heart of any gaming console is its processor. It is responsible for the raw power of the unit, whilst also linking all of the other components such RAM, hard disk drive, graphics chip and optical drive together.
The PS4 and Xbox One use very similar CPUs, both using the Jaguar architecture made by AMD and consisting of two quad-core modules giving a total of 8-core units.
The Xbox One runs at 1.75GHz, although it was original specified as 1.6GHz but increased before launch by Microsoft engineers. The PlayStation's processor speed has not been officially released by Sony, although it is said by industry experts to be running at 1.6GHz. Although this is slower than the Xbox, it is a relatively small difference that it is unlikely to provide the Xbox with any noticeable real-world advantage. There is also an indication that the Sony product has a boost feature where the CPU speed can be momentarily increased when CPU intensive demand occurs, although this has not been confirmed by the manufacturer.
A benefit of both consoles using very similar architecture is that producing games for each system doesn't have to be approached from two difference technical perspectives. A title written for the PS4 is free to be ported across to the Xbox One without any major re-engineering. This principle also applies to PC versions of games because the CPU used is a PC derived x86 architecture whilst the graphics processing is also PC based.
Both consoles use an Accelerated Processing Unit (or APU) setup. This system has both the CPU and GPU (graphics processing unit) contained on one chip. These new-generation consoles use AMD's third generation lower power APU [url="http://google.co.uk"]architecture[/url].
