If there is an earlier 14 nm tapeout on ARM then x86, then his claim has some validity.

I don't know exactly what Warren East meant but i took it to mean that a PC processor has a lot of CPU and not many other cores while an mobile device app processor has not much CPU and a lot of additional cores, with different digital and mixed-signal requirements. All that IP, which Intel may have in 32-nm HKMG, has to be moved across to 22-nm FinFET.

@nc3 Looks like your right. http://eetimes.com/electronics-news/4391299/FinFETs-on-SOI-reduce-leakage-current--says-GSS Intel marketing is "good". They had us believing 10x lower leakage with trigate. Turns out 3x worse. So a factor of 30x marketing versus reality. Let's see how they market the news when they switch to SOI.

Intel is marketing new designs that are being manufacturing at foundry versus internal later this. LTE chip one example

@James7740 I think you are mis-using the numbers here to get to 30x. It is always important to reference what is being compared against. Intel 'tri-gate' FinFETs may well be superior to planar bulk CMOS, which is what most other companies are offering at present. But Intel triangular FinFETs are a few percent inferior to rectangular FinFETs on bulk silicon And rectangular FinFETs on bulk silicon are 2 to 3.5 times worse than FinFETs-on-SOI, according to GSS. As yet nobody is making FinFET-on-SOI although it may come. So Intel FinFETs may be the best for leakage performance in the market at present but not quite as good as previously hoped because of triangular cross-section, which may have been adopted for manufacturing reasons.

Peter, Here is the data. Intel 22nm device specs were published at vlsi 2012. Leakage current is 1 to 100nA/um. Foundry for mobile 28nm SOC is 10pA/um to 10nA/um. Foundry mobile is 10X to 100X lower depending on device. Intel will have a finfet soc in market in 2013. Since its not in market we don't know leakage. Intel will improve finfet and improve leakage but my guess it will match foundry leakage (not beat it) Can you share your reference that intel is shipping lower leakage with finfet than Foundry and what leakage number you are using vs ( 1-100nA/um I ref.) Intel does not have

Peter, Here is some more Intel leakage data. I understand there is confusion in media on this.  Another data point on this is from Intel's 22nm product. See Toms hardware comparing 3.5 Ghz parts idle power increase for 22nm trigate compared to 32 planar : 71W vs 66W. Transistor leakage is a key component of idle power. see next quote in article as well. "Intel admits that it didn’t do much of anything to cut Ivy Bridge’s power consumption beyond its adoption of 22 nm lithography. It’s not surprising, then, that idle power use doesn’t really change compared to last generation." http://www.tomshardware.com/reviews/core-i5-3570-low-power,3204-13.html# So product shows ~ same leakage, ~same performance (3.5Ghz). Explaining this unexpected result on leakage and performance could be a great article.

SoCs have up to three different voltages with corresponding gate oxide thicknesses. I/O typically uses 0.18 um 3.3 V for example. The finfet cost and complexity has to be included with non-finfet portion for overall SoC process cost-effectiveness consideration.

Intel's Mark Bohr has been saying for awhile now Intel has separate SoC and processors variations of its process tech at every node. I believe the SoC variant my lag by some time period.
