The Sony PlayStation 4 games console shares much of its hardware technology with the personal computer. We take a look at how it compares with a gaming computer in terms of price and performance.
The PS4 uses a graphics processing unit (GPU) based on the Radeon HD 7000 series of gta code cards that are designed by AMD. It has 18 compute units with 64 cores per compute unit, giving it a total of 1,152 cores. This gives the PS4 a theoretical peak performance of 1.84 TFLOPS that can be used for graphics, physics simulation or a combination of the two.
There are several known differences between the PS4's GPU and the AMD 7870 PC graphics card upon which it is based. The first is that the PS4 unit has a dedicated 20 GB/s bus bypassing the L1 and L2 GPU cache to allow for direct system memory access. Direct memory access (usually shortened to DMA) in this instance serves to speed up the graphics by reducing the number of processes required.
It also has additional L2 cache support for simultaneous graphical and asynchronous computing tasks thanks to the inclusion of a 'volatile' bit tag. This allows the machine to process graphics and computational code synchronously, without suspending one to be able to run the other.
