| Netyaroze said: The profit margin on the APUs in both consoles are very slim so why would AMD waste their precious capacities on something that is contractually fixed already. 20nm for PS4/Xone will come but only when the process matured enough and they made first some bucks on their own PC GPUs. |
you really don't know how these things work. Yes all rumors and pics are fake. Not talking about that.
Waste their precious capacities? what the hell are you talking about?
And how many times will I have to say this to you, one of the benefits of disabling GPU cores (the amount of shader cores that are made are so much that this is where defects are most likely to pop up.) is that you do not have to wait until Feb processes becomes more mature before you adopt the new fan tech. You just keep ignoring that and I keep saying it over and over again.
Actually here.... tired of repeating myself.
and a small quote from the above link.
"The move from one production node to another historically takes much longer on console, as existing production technologies become more reliable (meaning a higher chip yield per wafer). However, it's clear AMD has incorporated measures into both Xbox One and PS4 processors to make the transition onto small fabrication technologies faster this time around. On the silicon itself, the graphics portion of the processor features a full 14 compute units on Xbox One and 20 on PlayStation 4. In both cases, two compute units are disabled on the final retail units in order to increase production yield.
The 28nm production process was very mature by the time the new wave of consoles went into production, meaning there was probably little need to disable any part of the chip on either console. Indeed, in our Xbox One architects interview, the team discussed with us how they could enable the full 14 compute unit graphics hardware on development systems for testing purposes. However, deactivating those parts of the chip means the technology should be able to transition across to 20nm more quickly - the production yield per wafer increases as the chips don't need to be absolutely perfect. In short, both the Xbox One and PS4 processors were designed to be cheap to produce on current 28nm production technology, but flexible enough to move across to more advanced fabrication nodes more quickly than their predecessors."
