363mm^2 Cost

Suspected such a large device 363 mm^2 on 28 nm process, fabricated ahead of its process economics, which did not sound like the TSMC mantra of effective capacity utilization vis-a-vis the marginal cost of other high end product's wafer starts.

Did some research and found prior xBox tear down suggesting processor at 20% of B.O.M.

At $499 retail processor cost then approximately $100. That is .27 cents per mm^2 of dice area which is competitive with Intel's fully burdened cost of production. 

On AMD price for the design effort I personally suspect the part in the $125 range. That is .34 cents per mm^2 of dice area.  This embedded x86 APU in relation to commercial market product is still quite a bargain for the dice area.

@Rick, thanks. so the chip is not that complex and if some parts of the chip are repairable then it can increase the overall yield.

So is this SOC a wide and slim fabrication with fewer layers and easy interconnect?  Or is this chip a a multi later behamouth?  One's less costly and the other . . .

What's the fabrication structure?

Since many threads of comments have come up discussing about the price of the processors, I would like to share my opinion about the technology driven products. The products should be made keeping in mind reusability of the heavily priced components. Do you think it is necessary to have so many high end processor in every home residing in laptops, desktops, game consoles, tablets and many more. The gaming consoles with very varied interfaces should be avoided by the designers and they should use the standard interfaces used in the computers that way reusability of hardware will be more justified.

 BTW, this design was the pack-it-all in first interation. The next round is cost reduction...if they can find a sub 28nm process that offers that these days
