Microsoft Xbox One, Sony PlayStation 4 APUs compared

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.
