Intel’s 2011 Investor Meeting - Intel’s Architecture Group: 14nm Airmont Atom In 2014
Today Intel is holding their annual investors meeting at their Santa Clara headquarters. In true Intel fashion it’s being treated as a big event (ed: it’s so big they ran out of lunch), as this is the company’s primary vehicle for addressing the investors holding their 125 billion dollars in shares; in essence it’s a reprise of their current and future technology plans as a pep-talk for investors. As such it’s not really a technical event, but it’s not uncommon for a few new technical details to shake out during the presentations.
There are a number of presentations throughout the day, including keynotes from Paul Otellini, and presentations from a number of Intel groups including the architecture group, the data center group, and the manufacturing group. If something is going to shake out it’s bound to be the architecture group, so this is where we’ll start.
A big part of the architecture group’s discussion focused on Atom/SoC. The 32nm Medfield Atom is due this year, so Intel has been laying out their plans for what they’re going to be doing with Medfield. Unsurprisingly, a big push with Medfield is to break into the SoC space in a way that Moorestown could not. Intel never managed any major design wins for smartphones with Moorestown, which is something they want to correct with Medfield. To that extent Intel has been showing off Medfield concept phones to show investors that it’s a viable product and to try to drum up support.

Intel is also spending some effort to dispel the idea that they can’t be competitive on a power consumption basis; in fact for the amount of effort they put into that message and the number of times they repeated it, they seem to be seriously concerned about being perceived as uncompetitive. Intel did some power consumption testing on Medfield and put together a slide showing their findings that Medfield is competitive with some current leading phones, but as always take this with a pinch of salt. Ultimately this is a comparison of 32nm Medfield with 4Xnm ARM SoCs, so it’s only applicable so long as Intel’s still ahead of the ARM producers on manufacturing technology.
Moving on, one thing Intel has been dealing with as Atom has evolved is how to consolidate all the disparate parts of a system onto a SoC, given the wide variety of uses for a SoC. With discrete components manufacturers could simply build a device out of the parts necessary for the features they need, but with Atom SoCs much of that gets shifted onto Intel. For Intel this means they will be focusing on producing a wider variety of SoCs, based on building up individual SoC designs on a modular basis. Intel isn’t going in-depth on how many specific SoC variants they’re planning on offering, but our impression is that there will be many variants, similar to how Intel offers a number of different desktop/laptop/server CPUs based on a common architecture.
Finally, Intel published a new generalized roadmap for Atom through 2014. Unfortunately they aren’t going into any significant detail on architecture here – while Silvermont is named, nothing is confirmed besides the name and manufacturing process – but it’s a start, and it ends with a shocker. We will see Silvermont in 2013 on Intel’s 22nm process, likely hand-in-hand with Intel’s aforementioned plans for additional SoC variations.
Far more interesting however is that Intel didn’t stop with Silvermont on their Atom roadmap. Intel’s roadmap goes out to 2014 and includes Silvermont’s successor: Airmont. We know even less about Airmont than we do Silvermont, but a good guess would be that it’s the tick in Intel’s tick-tock cadence for Atom. The biggest news here is that with a move to tick-tock for Atom, Intel is finally accelerating the production of Atom parts on their newer fab processes. Currently Atom processors are a year or more behind Core processors for using a new process, and even with Silvermont that’s still going to be the case. But for Airmont that window is shrinking: Airmont will be released on Intel’s forthcoming 14nm process in 2014, the same year as their respective Core processor. Intel hasn’t specified when in 2014 this will be, and it’s likely it will still be months after 14nm launches for Core processors, but nevertheless it’s much sooner than it has been before.
By accelerating their production of Atom on new processes, this should allow Intel to capitalize on their manufacturing advantages over the rest of the fabs. With Intel’s existing Atom schedule, they only have a year or less before other fabs catch up with them, so by putting Atoms on new processes sooner, they increase that lead time. So far Intel’s ARM SoC competitors have really only had to deal with Intel’s threats on an architectural level, so having Intel challenge them at a manufacturing level too will make Intel a much more threatening competitor.
Meanwhile, for the rest architecture group’s presentation, it was largely a catch-all for all of Intel’s consumer technologies. Much of the talk focused on where Intel plans to be in the next few years, based on where they expect to be thanks to their newly announced 22nm process. Intel considers their 22nm process to be a significant advantage for their products, so a great deal of their plans in the consumer space involve exploiting it in some manner or another.
Ivy Bridge, Intel’s first 22nm product, is being shown off in a few sample systems with Intel reiterating that it will be launching at the beginning of next year – we’d guess at CES. Longer term, Intel wants to get laptops closer to netbooks/tablets in terms of size and battery life, so that they can push 10 hours on a laptop (something the C2D-based Macbook Air can already get very close to). The catalyst for this will be Haswell, Intel’s new microarchitecture on their 22nm process scheduled for 2013.
Intel also used the occasion to show off a couple new technologies that they’re working on for Ivy Bridge generation computers. We’ve heard the name Fast Flash Standby mentioned before, but as far as we know this was the first time it has been demoed. In a nutshell, Fast Flash Standby is hibernating to SSDs, another product Intel has a significant interest in. The basis for Fast Flash Standby is that while going into sleep is fast, it requires leaving the RAM powered up to hold its contents, which is why sleep is only good for a few days of standby versus weeks for hibernation. Hibernating to a SSD, particularly one with a very high sequential read and write throughput, allows hibernation to take place much quicker and to resume much sooner. Intel is doing more here than just writing a hibernation file to a SSD, but the concept is similar.
Longer term Intel is looking at what kind of markets they want to go after, and what architectures they need to reach them. Intel is talking – albeit nebulously – about a new 10-20W notebook design target to sit right above their sub-10W target for Atom/SoC. Currently Intel offers CULV Sandy Bridge processors in the 10-20W range, but Intel appears to want to go beyond CULV with this new target. Whether this is a bulked up Atom, or a further trimmed IB/Haswell/Skylake remains to be seen. Intel is throwing around some performance targets however: they’re looking to improve iGPU performance by 12x over today’s performance in that 10-20W envelope.
