It's a single question about the PS4 point is that what makes the chip scale of how much. Here also, the financial woes of Sony cast a shadow. Chip increases, the increase not only the cost of the chip itself, but also the cost of the cooling mechanism, the total cost will increase. If the cost is high and PS4, it will be a drag on Sony's results of operations at the time of sale, it could also develop problem management responsibility lies. Should as Sony can not force, as well specs, I would not be reasonable to some extent should be pressed. However, I have not even thought not prepared to put on management responsibility, and make a PS4 with negative net worth. However, as a practical matter, it would be difficult.
 The deeply involved in this issue is the process technology. AMD for mainstream products, switch to the 28nm bulk process from 2013. (Silicon-on-insulator) process is used only when it comes to high-end products, SOI, it might be difficult to think of a line and secure. In any case, now GLOBALFOUNDRIES, AMD has commissioned the production of CPU & APU and main stream performance, SOI for 28nm is unclear at the moment.
Foundry business process roadmap PDF version is here.
 Given this situation, the process technology to be considered in the PS4 chip, 28nm bulk first.
There may be 20nm PS4 shipment time if the second half of 2014. If it was 28nm process, the number of transistors to be placed on the chip than 32nm SOI, but increase, we can not expect performance up against 32nm SOI. On the further miniaturization, performance can be expected to some extent if 20nm. However, 20nm of GLOBALFOUNDRIES is not different from the 22nm 3D transistors of Intel. Detailed verification is done later in the article,
basically likely to be on the level of mid-range PC of the year 2013-14.
