We take a look at how it compares with a gaming computer in terms of price and performance.
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.
The question as to whether a PC is better than a PS4 depends of the way in which you carry out the comparison. In this article we look at the comparison from a cost equal standpoint. In a later article we deal with the comparison on an outright performance basis.
There are several reasons why this is the case. The first is that games console has a large advantage due to the lack of a resource hogging operating system such as Windows. A PC needs to be able to do a lot of things, often simultaneously. To allow this, the operating system needs to be comprehensive, often taking a lot of the machines free resources just to run. This allows the PlayStation to get away with a lower overall specification while still being able to maintain performance.
The second is that the manufacturers producing consoles often sell at a loss due to the need to gain market share and out sell their rivals. This is especially true at the early stages of a console's life when development costs are being recouped. The PS4 v Xbox One is one of the biggest sales battles in the technology market which looks set to continue for many years to come. It is obviously difficult to compete with a product that is subsidized by its manufacturer.
Cost is not only the consideration when comparing the two. Computer users often have the rest of their system in place so more funds are available to spend on the graphics hardware alone, whilst to some outright performance is the only consideration.
The new generation of consoles is not just gaming devices though; your Free Sony PS4 can also function as a fully featured media centre thanks to its integrated Blue-ray drive, wireless connectivity and 4K capability. For the full specifications of the console please check out our website above. We also have an excellent PS4 vs. Xbox One section if you're still undecided on which console is best for you.
In our previous PS4 v PC Graphics article we considered the graphics performance of the Sony PlayStation 4 against a personal computer using systems that were comparable in cost. Outright Performance - PS4 v PC Graphics
The elimination of budgetary factors leaves us free we consider the very latest graphics cards and in this instance the games console has several reasons why it cannot compete with high end PC graphics.
Graphics cards such the Radeon R9 and NVIDIA GeForce GTX 700 series are the high-performance examples of graphics cards on the market. Games consoles such as the Xbox One and PlayStation will have a maximum power draw of around 300W, whilst high end gaming computers can have power supplies reaching 1000W. Powerful processors, large power supplies and big casings with the large heatsinks and fans required to deal with the heat generated by a powerful gaming PC all cost money. High end gaming computers probably sell in much smaller numbers but the higher price of the hardware, particularly the graphics cards, allows for this niche sector of the market to continue.
In conclusion, the Sony PS4 and gaming PC's operating in two different areas of the marketplace. The form factor, upgradeability, power supplies and consumers demands for simply the best technology available allow this. Top end gaming PCs already have a clear performance advantage over the PS4, with games such as Battlefield 4 being able to run at a higher resolution and with higher quality textures on PC than on the console. Thanks to the combination a powerful CPU, well developed graphics processor and high quality GDDR5 RAM, the Sony PlayStation 4 is an excellent gaming machine.
