[QUOTE="Megahurtz, post: 157793, member: 3958"] This is a common practice to improve die yields. If a cpu comes out with a defective core, the processor has excess cores disabled and is binned as a lower tier product. The PS4 has 20 GCN Compute Units on the die, but the system only uses 18 of them. That way, if a die comes off the wafer with 2 bad CUs, it can still be used rather than throwing it in the trash. The new systems also reserve some CPU cores for OS/system level stuff. I think the xbone reserves two cores for multitasking. Not sure about the PS4, but it would have at least one reserved to manage OS stuff along, probably two of them also. [/QUOTE]
