| biglittlesps said: I heard some details before when there was some talk about yield problem of Xbox GPU, which is like PS4 and Xbox will have 20 and 14 Computer Units instead of 12 and 18 but two of them will be used for yield problems, so Sony might be trying to use these spare two units due to some good yields. I'm not sure about this just wanted to let you know. |
Putting in "More than needed" is a decades old engineering solution to get redundancy into dies (a few more memory cells in caches, a few more graphics units in the gpus. Just how many more is a difficult arbitration between ecpected waver defect rate and increased costs due to more die space). The Cell has one entire SPU for redundancy. And no, neither Sony nor MS will ever use more than the 18/12 CUs, because that is the very point of consoles: you have one fixed, constant forever pool of resources.
