A leaked Intel lineup reveals that the company's upcoming Bay Trail processors will also fall under not only the traditional Atom branding, but the Pentium and Celeron brands as well. The new lineup includes Bay Trail-D, Bay Trail-I, and Bay Trail M processors (note that Valleyview is the CPU codename, Bay Trail is the platform codename, with the CPU based on Intel's 22nm Silvermont architecture). The Bay Trail SoCs, which are based on the company's new 22nm Silvermont micro-architecture, include five processors in the Atom family, two in the Pentium family, and five processors that are part of the Celeron family.
All five of the Atom branded processors are Bay Trail-I chips. The leaked Atom lineup includes the following SKUs.
- Atom E3810 (Bay Trail-I): Single core at 1.46 GHz with 400 MHz GPU and 5W TDP
- Atom E3821 (Bay Trail-I): Dual core at 1.33 GHz with 533 MHz GPU and 6W TDP
- Atom E3822 (Bay Trail-I): Dual core at 1.46 GHz with 667 MHz GPU and 7W TDP
- Atom E3823 (Bay Trail-I): Dual core at 1.75 GHz with 792 MHz GPU and 8W TDP
- Atom E3840 (Bay Trail-I): Quad core at 1.91 GHz with 792 MHz GPU and 10W TDP
Further, there will be one Bay Trail-M and one Bay Trail-D Silvermont-based CPU under the Pentium brand. Specifications on those two chips are below.
- Pentium N3510 (Bay Trail-M): Quad core at 2 GHz with 750 MHz GPU and 7.5W TDP (4.5W SDP)
- Pentium J2850 (Bay Trail-D): Quad core at 2.41 GHz with 792 MHz GPU and 10W TDP
Finally, the new Bay Trail-M and Bay Trail-D SoCs under the Celeron brand includes two quad cores and three dual core CPUs.
According to this PDF, the N2805, N2810, and N2910 Celeron CPUs will have an MSRP of $132, though it seems as though the N2805 should be cheaper than that since it has much lower specifications than the other two. The new Celeron-branded chips have the following specifications.
- Celeron J1750 (Bay Trail-D): Dual core at 2.41 GHz with 792 MHz GPU and 10W TDP
- Celeron J1850 (Bay Trail-D): Quad core at 2 GHz with 792 MHz GPU and 10W TDP
- Celeron N2805 (Bay Trail-M): Dual core at 1.46 GHz with 667 MHz GPU and 4.5W TDP (sub-2.5W SDP)
- Celeron N2810 (Bay Trail-M): Dual core at 2 GHz with 756 MHz GPU and 7.5W TDP (4.5W SDP)
- Celeron N2910 (Bay Trail-M): Quad core at 1.6 GHz with 756 MHz GPU and 7.5W TDP (4.5W SDP)

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.
A block diagram of Intel's upcoming Silvermont architecture.
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?

There won't be any new Intel desktop processors for Christmas and even in the New Year it will be the entry level lineup that is first refreshed. Six older Pentium and Celeron models will hit EOL and be replaced with new Ivy Bridge based 22nm models, likely with similar specs and reduced power consumption. The news for mobile processors is a little better with the Core i7-3687, Core i5-3437U, Celeron 1037U, 1007U, 1020M and 1000M all slated for the first quarter of 2013. DigiTime also mentions a new 20nm member of the 530 series of SSDs should be arriving at the same time.
"Intel is set to upgrade its entry-level desktop Pentium and Celeron product lines in the first quarter of 2013 with the launch of Ivy Bridge-based 22nm Pentium G2130, G2020 and G2020T and Celeron G1620, G1610 and G1610T processors, while its existing Sandy Bridge-based 32nm Pentium G870, G645 and G645T as well as Celeron G555, G550 and G550T will be phased out of the market starting the end of 2012, according to sources from the upstream supply chain."

The eyes of the world are on the 22nm Ivy Bridge chip that Intel has slowly been giving us details of but there is also something interesting happening at 32nm with the world's most repurposed Intel CPU. Once again the old Pentium core has been dusted off and modified to showcase new Intel technology, in this case Near Threshold Voltage operations. In this case the Threshold refers to the amount of power needed to flip a bit on a processor, what you would be used to seeing as VCC and is the reason those dang chips get so toasty. Much in the way that SpeedStep and other energy savings technologies reduce the operating frequency of an underloaded processor, Intel has tied the amount of voltage to the frequency and lowers the power requirements along with the chips speed. The demonstration model that they showed The Register varied from a high end of 1.2 volts at 915MHz to a mere 280 millivolts at 3MHz and down to 2 millivolts in sleep. By scaling the power consumption Intel may have found a nice middle group between performance and TDP to keep ARM from making major inroads into the server room, if they can pull it off with more modern processors. They also showed off a solar powered CPU which might be handy on a cell phone but seems of limited commercial value in the short term as well as a
Keeping with the theme of small, The Register also has news of research which has created a working transistor out of a single phosphorus atom, an atomic radius of 0.110nm for those who like some scale with their transistors. The trick was the temperature; seeing as it is a measure of energy expressed as movement (to put it ridiculously simply) you need low temperatures to keep the atoms from moving more than 10nm. At -196°C the atom was stable enough for its position to be accurately predicted which is absolutely necessary if you plan to use the atom as a qubit. Overclocking is going to be difficult.
"The threshold voltage is the point at which transistors turn on and conduct electricity. If you can flip bits near this threshold, instead of using much larger swing that is typically many times this threshold voltage to turn zeros into ones and vice versa, then you can save a lot of power."

Intel has updated the Pentium processor for the SandyBridge era with the 32nm G620, G840 and G850, all of which cost under $100. All are rated at 65W TDP with 3MB of level 3 cache, an integrated DDR3 memory controller, PCI Express 2.0 interface, Direct Media Interface 2.0, and Intel HD Graphics 2000. Legit Reviews tested the 2.9GHz G850 model and found no surprises, neither good nor bad. The Pentium line remains the workhorse model, perfect for office usage, web browsing and even watching movies. Those who make movies or want to do more than basic gaming are better off looking at an older LGA1156 processor or even a slightly more expensive Intel or AMD chip. If you've a relative that only needs a PC for light duty tasks, consider a system built around one of these new SandyBridge Pentiums.
"After trying out both the Intel Pentium G620 and Pentium G850 we must admit that we are still impressed by what these cost effective mainstream processors can do. Thanks to the powerful Intel 'Sandy Bridge' microarchitecture these dual-core processors don't run too far behind the more expensive offerings from Intel and AMD. You can find some pretty good deals on LGA775 and LGA1156 platforms right now, but the Intel Pentium series for LGA1155 has more features and as you could see in the performance tests they weren't that far behind in the benchmarks..."
