My foundry contact has studied Intel's 22nm SOC FinFET manufacturing flow and claims that it is not cost effective (compared to foundry 28nm/32nm) to manufacture mobile chips hence even Intel over next 3 years will still make most of its Infineon mobile cell phone chipsets at TSMC.
Chips such as the 2 main chips in Apple's iphone 5: MDM9615 and A6 have an average ASP of $20 compared to similar die size X86 that Intel sells for $100-200)
I have seen others post this as well. Can you address why repeating the intel spin on "manufacturing show down" makes any sense when today most advanced atom SOC is on 32nm and will stay that way until end of 2013 ! while Qualcomm is shipping 50M units 28nm this year in just the iPhone 5 design alone and
(2) I thought all you guys were writing about intel winning mobile market with 22nm finfet last year (2011) and intel has not demo anything close to A6 CPU or graphic power/performance (at mobIle power level) .... Even demoed something close to what is already shipping !
I was not aware that Intel has a position on a "manufacturing show down" and therefore did not try to repeat it.
My intention was to tell readers that papers will be presented at IEDM on many of the leading-edge process technologies that will be producing chips in the near future. And therefore San Francisco in early December would be a good place to find out more.
The rigor of the IEDM review process means that these should be detailed, quantitative presentations albeit likely to be only on certain aspects of each of these processes.
From my perusal of the program the 14-nm logic node is being discussed mainly by academic groups looking at aspects of doping and strain in individual transistors.
To your second point. All what guys?
22nm not cost-effective ? I suppose that depends upon the level of integration. While it's probably not a cost-savings to replace small individual 32nm devices with 22nm, there is a definite cost-savings thru higher integration at smaller process geometries to reduce PCB area, total BOM, and possibly power-savings as well.
I hope your foundry contact is an ex-intel guy and he knows what he is comparing to. Most likely he is comparing what their FINFET will be in the COST sense. I will never doubt Intel's manufacturing cost much or significantly lower than foundry offering. Intel's biggest expense might not be in wafer manufacturing, they also need to cover IP/EDA tool development/product design teams, in addition marketing cost..... You should consider Synopsys/Candence/ARM/Virage../TSMC/SPIL/ASE../Qualcomm/nVidia.... before you start calculating the selling price. Too bad Intel can't just open its technology/manufacturing capability for design houses. You might want to check the baseband/AP SOC chips Clover Trail are made at TSMC or not? How about even 32nm SOC Medfield chip in TSMC? Who cares about legacy chips at TSMC? Also x86 atom is in the range 20x2 =40 price range. Nobody is using server chip for mobile phone. The war is getting more excited finally.
Confirmed--Intel baseband will use foundry (mostly TSMC) for next 2-3 years since Intel's internal cost is too high. This is because Intel's 22nm to get to yield has more restrictive design rules (increases die size). Restrictive design rules are on logic, analog, I/O, and back-end metal. Intel will never have competitive baseband chips in its 22nm SOC.
Same is true for Intel's atom line, 22nm SOC Intel chip name Valleyview)...it is that part again due to the restrictive design rules that will not be competitive on cost.
