The PlayStation 4’s central processing unit has a clock speed of 1.6 GHz.
The PS4 uses an AMD Jaguar CPU arranged as two quad-core modules, giving the console eight x86-64 cores in total. The processor is integrated with the graphics processor and memory controller in a single accelerated processing unit, or APU.
The 1.6 GHz figure applies to the original PS4 and the later PS4 Slim. It is a base clock specification for the CPU cores, not the speed of the console’s 8 GB GDDR5 memory, which is often discussed separately. The CPU was designed for balanced console performance rather than extremely high desktop-style clock speeds.
A common mix-up involves the PS4 Pro, released in 2016. Its CPU architecture remained based on Jaguar, but its clock speed increased to 2.13 GHz. The PS4 Pro also doubled the number of active GPU compute units, making it substantially stronger graphically. That higher figure should not replace 1.6 GHz when the question specifically asks about the original PlayStation 4.
