I go by the price of the AMD chips at retail vs. the $37 cell of 2009. I have no doubt the 360 cpu cost the same or less before it was integrated with the gpu.
Why are you comparing cell of 2009 vs amd chips of 2011.
Why don't you instead compare a amd chip made in 2005/6 like cell to what it cost for the same chip for amd in 2009.
Remember cell was a 90nm chip and is now on 40nm .

According to them in 2006 the xenon was $106 and the gpu was $141 .
So for MS at least they were willing to devote at least $250 for the cpu and gpu alone.
The cpu price for an amd chip you see at retail once again has serveral layers of mark up that the chips amd/ibm/whoever sell to ms and sony.
For a retail amd chip you have the cpu cost , you have the packaging cost , you have the heatsink/fan cost you have the the shiping cost. Then you have the retailers portion.
These all add up over the cost of what sony buys a cell chip for or ms buys a xenon for.
You also forget that prices of cpus in the market change drasticly and quickly.
So lets think for a second. Lets say MS goes with a 4/8 bulldozer. Over the course of the 6-10 years AMD is going to make this chip for MS it will change process nodes hopefully many times (lets hope we can keep going smaller or find new ways of making chips faster and cheaper and bigger) each time it costs amd less to make the chip.
With any deal MS would pay the cost to manufacture plus then an agreed upon fee per chip. This could be small , $10 or so per chip mabye more. It could also start higher and decease over time depending on how the companys want to play it.
Both companys here make out as each process shrink the chip costs less for MS to buy but amd is making the same amount of money and with each shrink it takes up less fab time for the same amount of chips.
Now in the short term amd may make more by selling these bulldozers on the market. I wont disagree with that. However
Bulldozer 4/8 comes out this year and i think we all agree we wont see new consoles this year. So lets say the new system coms out next year. That means the bulldozer 4/8 cpu has been out ofr a year already. Lets say this year we see 3ghz - 3.5ghz speeds. MS went with 3.2ghz speeds for the console in 2012.
So in 2011 amd is already pricing these at diffrent levels. 2012 comes around and intel has new chips and so now amd has to price drop again. The ASP of the bulldozer chips have already changed before the ms system launches. Yields have gone up and the cost ot make them for amd has gone down.
now enter MS . MS needs millions to launch and AMD agrees to make them and as amd makes them they tweak the process , yields go up and costs go down . So now because of that the cost per bulldozer sold to the pc market is less . So now amd is making more per bulldozer chip.
But 2013 comes out and those 4/8 bulldozer chips are now mid range chips instead of high end chips. So now those chips have an even lower ASP. But now Amd moves to a new micron process and they are making 8/16 chip bulldozers. Once again the asp of the 4/8 chips have gone down. The 8/16 chips are now their big sellers. But they are still making the same 4/8 chips for ms tand they can make more 4/8 chips per wafer than the last micron process . Now while the bulldozer chips in the pc market are considered low end chips amd is still making the same profit per bulldozer sold to MS .
Amd's costs of supplying MS have dropped. a micron drop allowed them to fit more 4/8 dulldozers on a wafer which brings down the cost per chip . MS is still paying them that fixed rate over the cost of the chip. Since more 4/8s can be made per wafer amd is devoting less time to making ms's chips .
On MS's side the costs for the 4/8s have gone down , the fee they pay AMD per chip is the same but the cost of the chip has decreased due to better yields and a smaller micron process.
Now we skip to 2016 . 4/8 bulldozers are old news and no one cares about them. They don't even sell bulldozers to the pc market anymore they have a whole new cpu design out there. But now they have droped another 2-3 micron processes and those 4/8 chips are dirt cheap but they are still collecting that fee from MS and they are still able to sell ms millions of 4/8 bulldozer chips to MS and collect that fee from ms.
In 2016 producing these chips would take very very little fab capacity from amd , they would be netting x amount per bulldozer that long since stoped making them money in the console sector.
Now a 2012 console would only be in its 4th year in 2016. It would have the potential to continue selling till 2020 -2022 and continue to bring in revenue to AMD
Do you see where there is the upside for AMD in this situation ?
The only way this wouldn't work in AMD's favor is if they odn't have the fab capacity to create the chips , which i don't think is the case.
