Talking about Xbox One’s APU, it features eight cores clocked at 1.6GHz. Microsoft’s next gaming console has only 768 stream processors in its Video chip and the memory is a quad-channel DDR3 clocked at 2133MHz – giving it a total bandwidth of 68.3 GByte/s.

Sony PS4 on the other hand also has an eight core APU clocked at 1.6GHz. But, the similarity ends there as Sony has put in Radeon graphics card with a whopping 1152 stream processors and put in 8GB of DDR3 GDDR5 memory clocked at 5.5GHz linked to a 256 bit memory interface. This gives the PlayStation 4 a whopping bandwidth of 176 GByte/s. Xbox One lags a lot when it comes to this.

Microsoft’s workaround? – well the operating system giant has integrated a 32 MB of SRAM-cache capable data processing at 102 GByte/s and that too at lower latencies as compared to PS4’s DDR5. Microsoft has claimed that this mechanism has given the Xbox One a memory bandwidth of 200 GByte/s – this seems to be too good to be true though.
