In addition to the impending launch of Intel's desktop Haswell processors, the company is also working on new Atom-series chips based on Intel's Silvermont architecture. Ryan Shrout wrote about the upcoming Atom architecture a few weeks ago, and you can read up on it here. However, in short, Atoms using the Silvermont architecture are 22nm SoCs with a Hyper Threaded, dual-module quad core design that comes with burst-able clockspeeds and up to 2.5x the performance of chips using the previous generation Saltwell architecture. Intel is promising up to a 50% IPC (instructions per clock) increase, and 4.7x lower power versus previous generation Atom CPUs.

With that said, over the weekend I read an interesting article over at PC World that hinted at these new Silvermont-based Atom processors taking up the Pentium and Celeron branded CPU mantle. In speaking with Intel employee Kathy Gill, the site learned that Intel will be using the Silvermont architecture in code-named Bay Trail-M and Bay Trail-D processors for notebooks and desktops respectively. The Bay Trail code name isn't new, but Intel's use of the Pentium and Celeron branding for these Atom chips is. For the past few generations, Intel has re-purposed lower-tier or lower binned Core processors as Pentiums or Celerons by disabling features and/or clocking them lower. It seems that Intel finally believes that its Atom lineup is good enough to serve those low-end desktop and notebook CPU purposes under the budget brand families.
Kathy Gill further stated that "we aren't ready to disclose additional details on Haswell plans at this time,” which does not rule out Haswell-based Celeron and Pentium chips. It does not confirm them either, however.
After a chat with PC Perspective's Josh Walrath on the issue, I'm not certain which direction Intel will take, but I do believe that Intel will (at least) favor the Atom chips for the Pentium and Celeron brands/lines because the company will see much better profit margins with the Silvermont-based chips compared to Haswell-based ones. On the other hand, Intel would lose out on the ability to re-brand low binning Core i3s as Pentium or Celeron CPUs. Further, going with both architectures would complicate matters and invite a good amount of brand confusion for many consumers in spite of allowing a mix of better profit margins and re-purposing chips that otherwise wouldn't make the cut (admittedly, Intel probably has to artificially limit some number of chips to keep up with the volume of Pentium and Celerons needed, it's difficult to say to what extent though).
Hopefully we will know more about Intel's Bay Trail CPUs and branding plans at Computex later this week.
What do you think of this move by Intel, and will the Silvermont-based Bay Trail chips be up to the task?

The news today is all about shrinking the Atom, both in process size and power consumption. Indeed The Tech Report heard talk of milliwatts and SoC's which shows the change of strategy Intel is having with Atom from small footprint HTPCs to POS and other ultra-low power applications. Hyperthreading has been dropped and Out of Order processing has been brought in which makes far more sense for the new niche Atom is destined for.
"Since their debut five years ago, Intel's Atom microprocessors have relied on the same basic CPU core. Next-gen Atoms will be based on the all-new Silvermont core, and we've taken a closer look at its underlying architecture."

A much needed architecture shift
It has been almost exactly five years since the release of the first Atom branded processors from Intel, starting with the Atom 230 and 330 based on the Diamondville design. Built for netbooks and nettops at the time, the Atom chips were a reaction to a unique market that the company had not planned for. While the early Atoms were great sellers, they were universally criticized by the media for slow performance and sub-par user experiences.
Atom has seen numerous refreshes since 2008, but they were all modifications of the simplistic, in-order architecture that was launched initially. With today's official release of the Silvermont architecture, the Atom processors see their first complete redesign from the ground up. With the focus on tablets and phones rather than netbooks, can Intel finally find a foothold in the growing markets dominated by ARM partners?
I should note that even though we are seeing the architectural reveal today, Intel doesn't plan on having shipping parts until late in 2013 for embedded, server and tablets and not until 2014 for smartphones. Why the early reveal on the design then? I think that pressure from ARM's designs (Krait, Exynos) as well as the upcoming release of AMD's own Kabini is forcing Intel's hand a bit. Certainly they don't want to be perceived as having fallen behind and getting news about the potential benefits of their own x86 option out in the public will help.
Silvermont will be the first Atom processor built on the 22nm process, leaving the 32nm designs of Saltwell behind it. This also marks the beginning of a new change in the Atom design process, to adopt the tick/tock model we have seen on Intel's consumer desktop and notebook parts. At the next node drop of 14nm, we'll see see an annual cadence that first focuses on the node change, then an architecture change at the same node.
By keeping Atom on the same process technology as Core (Ivy Bridge, Haswell, etc), Intel can put more of a focus on the power capabilities of their manufacturing.
