In order to be competitive your new core needs to leapfrog the previous generation cores of your competition by a good margin, especially when you already use the best process. 20nm TSMC is around the corner, and so are several more 64-bit ARM cores (besides Apple A7). That's what Silvermont will have to compete against next year, so let's see what your analysts say then.
ISA does certainly matter at lot despite claims to the contrary. However even if you just consider the ecosystem, it's hard to deny that x86 is at a distinct disadvantage there with virtually no presence in MCUs. Intel needs to try to compete in IoT of course (or again lose out like with mobiles), but the question is whether it is possible for them to compete using something like Quark. I refer to my leapfrog argument again, why would anyone switch to x86 if there is no compelling reason to do so?
Intel should let it go its Ego. It is too late and culturely not fit for Intel going to Mobile World with its x86 SoC. Once Intel gives up on that, Mobile will become money making business instead of money loosing business by offering foundry services to Qualcomm and Appple.
@resistion, agreed. Any SoC vendors, especially in the mobile world, would have to think long and hard before going to Intel for having their chips fabricated by them. They should be "scared," as you point out. The competitor angle should not be underestimated.
Rick, I'd say Quark is exactly the sort of thing that convinces me that Intel doesn't have a clue. Who wants an ancient and slow 486 to replace their current fast and efficient RISC MCUs? If this is something the new CEO pushed for, then I believe things won't improve at all - when does Intel get the message that x86 everywhere is just a crazy idea?
Atom is another example - why spend 5 years trying to shoehorn the same old and uncompetitive design into mobiles when you see all your competitors release new CPUs every 6 months or so? The disadvantage of the x86 ISA is such a millstone that even having the most advanced process cannot mitigate it. The new Silvermont can barely keep up with older 28nm ARM designs despite being made on the worlds most advanced 22nm process...
If they keep repeating the same mistakes then it won't even be their choice - to survive, all they could become is a foundry.
@ Rick Merritt. In general I find your opinions spot on. However not in this case. You have titled your article as " ... inflection point ". That is a term which has crept into common usage from Mathematics & then EE but perhaps not fully comprehended. Such points are characterized by very sudden & severe changes in gradient - not visible from 30,000 ft and require close monitoring. So what is needed "...inside" is someone at the helm who can call the shots based on hard personal knowledge where there is weakness / delay i,e. architecture and design and not lose focus, as you have rightly pointed out, by dabbling into lower margin Foundry services where the incumbent feels conmfortable in because of his Process background. A person with strength in Design would not have even considered that diversion seriously.
@Junko: Interesting parallel with Intel and the japanese giants it once fought.
I think things will have to get pretty painful for Intel before it gives up the high margin processor busienss for the lower margin foundry busienss. It doesn't even have the skills for the high product/process mix that busienss requires.
@Chipmonk and resistion: I think Intel has plenty of good processor and circuit designers, but they are still far behind Qualcomm in having mobile SoC blocks and exptertise--despite years of efforts.
Re the CEO (BK) I don'[t think it maters if the CEO is a process, design or sales guy as long as he undewrstands the 30K-foot issues in all three areas. I think BK's Quark move shows he understands those issues and as an insider he knows how to work the levers at Intel to get stuff to happen fast.
That said, the mobile train left the station a couple years ago and Intel is still running behind it waiving its hat and carrying its suitcase.
