Final Words
Silvermont really is Intel’s Conroe for the mobile market, but not in the sense that many have been expecting. Given that success in mobile is so closely tied to device wins, Silvermont alone isn’t enough. Unlike Conroe, a very competitive Silvermont won’t change the world overnight. What Silvermont does however is offer a great foundation for Intel going forward. Conroe lead to Penryn, Nehalem, Westmere, Sandy Bridge, Ivy Bridge and soon, Haswell. It was the platform that Intel could build on regularly by executing on tick-tock. Conroe paved the way for the insane advantage Intel has held onto for the past few years. Silvermont is like Conroe in that it provides that same foundation.
The mobile market is far more competitive than the PC industry was back when Conroe hit. There isn’t just one AMD but many competitors in the SoC space that are already very lean and fast moving. There’s also the fact that Intel doesn’t have tremendous marketshare in ultra mobile. Silvermont may feel a lot like Conroe, but the market it’s competing in is very different. That’s not to say that Intel can’t be successful here; it’s just not going to be easy.
Architecturally Silvermont is very conservative, and that’s not a bad thing. A side effect of not wanting to make Haswell irrelevant by a far lower cost part is the benefit of maintaining power efficiency. Intel joins the ranks of Apple and Qualcomm in intelligently scaling performance while respecting power consumption. Intel’s 22nm process should give Silvermont a lot of runway to use. If it can quickly follow up with 14nm, Silvermont’s power advantage could end up being akin to Conroe’s performance advantage in the mid-2000s.
Even so, Silvermont is long overdue. It’s the first mobile architecture where Intel really prioritized smartphones and tablets, and on paper, it looks very good. Now it’s up to Intel to turn a great architecture into great design wins. From what I’m hearing, we may actually see that happen.

In the first sentence of the paragraph below the Saltwell Vs. Silvermont graph, it states "In terms of absolute performance, Saltwell’s peak single threaded performance is 2x that of Saltwell" and it should be "Silvermont's peak single...."ClockworkPirate - Monday, May 6, 2013 - link
Also at the end of the first paragraph on the "Tablet Expectations and Performance" page, "...with Haswell picking up above Haswell." should probably be "...with Haswell picking up above Bay Trail."chrone - Monday, May 6, 2013 - link
this is the soc i've been waiting for since 2008. winter is coming!! it's gonna be a long winter for arm and friends ahead. \m/theos83 - Monday, May 6, 2013 - link
lol...wait and watch...it has been a long winter for intel (from a mobile market point of view), lets see what they end up with in the next 4 years...ARM and friends are not going away anytime soon.Hector2 - Friday, May 17, 2013 - link
True. The difference between then and now is that Intel didn't have an SoC designed and optimized for smartphones. Now they do (this year) and it'll be about 22nm & 14nm offering Intel higher performance, lower power and lower cost. In this area Intel has about a 2 year lead on their competitionKrysto - Monday, May 6, 2013 - link
It's very, very, VERY hard to beat a monopoly in a certain market (ARM that is), even with a company like Intel that may have a monopoly in another.Plus they have like a dozen competitors there, with at least 3-4 top ones. Intel has promised a lot of stuff before, and under-delivered. So we'll see. ARM chips are also going 20nm and 64 bit next year, and at 14nm FinFET the year after that (yes, only a year later).
Plus, if these things cost 2-3x what the high-end ARM chips cost, they can just pack and go home. No OEM will accept that, unless Intel gives them Haswell in PC's for 30% off, or some deal like that (which would mean they won't be making any money on these Atoms anytime soon).

Intel has the cash to loss-lead on this and open a big crack into the market. It also has the bucks to advertise.My guess is that shareholders are screaming for Intel to get into this market. All the omens look good and I am really looking forward to a big jump in power and battery life for mobiles. I think ARM finally has a real competitor.

Intel (and MS) are still under the delusion they're in the 1990's where they could be a premium vendor. Look at all the Windows tablets for proof of this. Intel and MS are both charging way more than they should and all their Wintel tablets (RT or 8) are overpriced by a huge amount.Intel doesn't loss lead. At least, they haven't shown any sign of it at all. Maybe this will be their moment, but somehow... I really, really doubt it.

Don't confuse Intel with the OEMs and MS, Intel isn't over charging on their hardware!The listed Tray cost for the Clover Trail Z2760 SoC is only $41, at a time when ARM high end SoCs are starting to go over $30... So there's not a multiple times cost difference anymore.
OEMs just mistakenly took their cue from MS pricing of the Surface and it's not like the tablet market is really set up for PC configurations.
OEMs for example are used to using internal drive capacity as a way of charging more of their products. Like it doesn't cost anywhere near $50 to double the drive capacity of a Nexus 7 for example or how Apple charges a $100 for each doubling of capacity.
Remember, Windows tablets start with 32GB and that's much higher minimum than what mobile devices still offer.
Along with inclusion of full size USB ports, the added cost of Windows license, the greater tendency to include premium parts like WACOM digitizers, etc all added together for how the pricing finally came out...
However, the OEMs should have learned their lessons, MS is definitely going to offer them better volume license fees this time around, and Bay Trail is suppose to be even lower priced than Clover Trail... So we should see much better pricing with this new generation of products.

Its not a monopoly. There are several companies that build ARM SoC's. ARM is an ISA, no different than x86. If Intel delivers quantity, better performaning SoC's than the competitors, best believe they will switch. Apple already does x86 in house on OS X. Promise you they have been testing Atom in house for potential future designs.. Whether those designs win over ARM A# in house designs is another matter... Intel is nothing if not good at getting companies to sign up with them.. They deliver the highest quality and highest quantities of anyone in the silicon business.
