The battle between Microsoft's Xbox One and Sony's PlayStation 4 in terms of their hardware and performance continues as a new report claims Sony's next-generation game console allows game developers to use up to 4.5 GB of its 8 GB of RAM. The other 3.5 GB is reserved for the PS4's operating system.
The PS4's game memory usage compares well to Microsoft's Xbox One, which allocates 5 GB of its own 8 GB of RAM for game developers. The article also claims that the Xbox One's RAM requirements are fixed and can't be changed, unlike the PS4.
The 8 GB of RAM inside the PS4 is of the GDDR5 variety, clocking at 5500 MHz for 170.6 GB/s of bandwidth. This compares to 8 GB of the older DDR3 RAM for the Xbox One, with a clock speed of 2133 MHz for just 68.3 GB/s of bandwidth, along with 32 MB of eSRAM that is supposed to have 102 GB/s of embedded memory bandwidth. A recent rumor is claiming Microsoft might be able to increase the speed of that embedded memory to 192GB/s for the final retail version of the console.
