Intel’s Atom processors were created as a tier below their Celeron product line. Netbooks, then running VIA Nano processors, have started to gain popularity since their introduction in late 2007. Intel’s Atom processors took the place of the VIA parts since that time. In 2009, Intel has stated that they have seen approximately twenty percent of their sales of notebook processors replaced with sales of their cheaper Atom processors. Intel still maintains the Atom processor line, but apparently with new goals in mind.
Up and ATOM!!!
According to Digitimes, the demand for Intel’s Atom processors has declined recently. Intel, in response, decided to market that tier of parts to embedded and server customers for use in network-attached storage devices and very low-end servers. Intel is also rumored to have plans to shrink the process size of Atom in 2013 to 22nm and again shrink process size to 14nm in 2014. The upcoming 32nm Atom processor is expected by the second quarter of 2012.

Intel hopes that 2012 will finally be the year they see mainstream phones with Intel inside. Despite Intel's attempts to tell us otherwise for the past several generations, the upcoming Medfield design is the first truly serious attempt to enter the phone and tablet market currently dominated by the many ARM-based partners of phone manufacturers all over the world. A recent post over at Technology Review discussed the advantages that Medfield offers over previous Intel Atom-based designs with Steve Smith, Intel's VP of Architecture.
First shown at the Intel Developer Forum in San Francisco this past September, a Medfield-based reference design has many believing in what some thought was impossible but what others thought was inevitable: Intel x86 cores in a phone that matters. Why the change from many in the analyst space? Medfield is the first option from Intel that is truly a single-chip solution, removing design space concerns and power consumption issues that previous Atom-architecture solutions were saddled with.
Intel showed Technology Review the Android-based reference phone running Gingerbread.
The phone prototype seen by Technology Review was similar in dimensions to the iPhone 4 but noticeably lighter, probably because the case was made with more plastic and less glass and metal. It was running the version of Google's operating system shipping with most Android phones today, known as Gingerbread; a newer version, Ice Cream Sandwich, was released by Google only about a month ago.
Intel has a lot of experience in the consumer markets though it took a shift inside the company to really put the focus on phones and tablets over netbooks and convertible-notebooks. At the recent showing not only did they have the reference design phone but also an iPad-like tablet device running Ice Cream Sandwich, another key to the consumer's dollar. And as you can clearly see in the diagram below, there is a lot of money being made that Intel wants in on. A LOT.

Intel will also enjoy a process technology advantage over the competition with current Medfield SoCs built on the company's internal 32nm process and the upcoming 22nm technology promises even more power consumption advantanges. ARM designs are built at different foundries including Samsung and TSMC and while they are competitive, no one can keep up with Intel on this front.
Anandtech also had some interesting information to share from an investor conference earlier this month about the power consumption and performance levels of Medfield.
The diagram shows that power consumption on Medfield should be competitive with the current ARM-based SoC leaders in the market today. Areas like 3G standby, basic audio playback and video playback should be accomplished with minimal power draw in order to have battery life extended to at least current expectations. The performance graphs here on Browser Mark and "Graphics" are impressive as well though obviously we have a TON of missing information to really make the graph meaningful. Anand puts it well:
Barring any outright deception however, there seems to be potential in Medfield.
I tend to believe that Intel is too smart to misjudge a product to investors, but remember how impressive the initial performance results of Larrabee were for years?
I am hopeful and excited for Intel's mobility plans in 2012 as other information we have seen looks impressive. Let's see what CES has to offer.
Speed Bumps and Unlocked Processors
AMD has announced the latest members of their fairly successful APU series for both the desktop and the mobile markets. The original release in June of this year saw the first fully integrated 32 nm APUs from AMD. These proved to be quite popular with their decent CPU performance and outstanding integrated graphics speed and quality. The launch was not entirely smooth for AMD though, even though the company had been shipping products to partners and OEMs for some months.
The desktop saw limited SKUs, and the availability of the top end parts was disappointing to say the least. AMD and their partners at GLOBALFOUNDRIES were not able to produce enough usable chips to supply demand. Quantities were tight throughout the summer, and the mobile market did not see as big of a boost for AMD as was hoped. AMD did get a lot of new business though, as the thermal and power envelopes of these A-series chips were able to match that of Intel.

Okay so the pun was a little obvious, but NVIDIA has just announced the specifications and name for the development kit used to develop for their ARM-based GPU computing platform. The development kit will provide a method to build and test applications on a platform similar to what will be found in the Barcelona Supercomputing Centre’s upcoming GPU supercomputer until you are ready to deploy the finished application with real data on the real machine. Such is the life of a development units.
Carma: What goes around, comes around... right Intel?
The development kit is quite modest in its specifications:
- Tegra3 ARM A9 CPU
- Quadro 1000M GPU (96 CUDA Cores)
- 2GB system RAM, 2GB GPU RAM
- 4x PCIe Gen1 CPU to GPU link
- 1000Base-T networking support
- SATA, HDMI, DisplayPort, USB.

Intel was far from demolished when AMD's Bulldozer came to town. Users still clung to hope that Microsoft's Windows 7 was not optimized to take advantage of Bulldozer's multi-core environment. Vindication came sweetly with a knowledge base article and a patch from Microsoft confirming the issue and offering a solution. While they can still feel comfortable knowing they were right, the solution has been pulled from Microsoft's website without any announced reason. Who should we feel sorry for: those who didn't download it yet, or those who did?
To be entirely fair, Microsoft's knowledge base article was quite clear in its instruction to users regarding this hotfix.
A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing the problem described in this article. This hotfix might receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next software update that contains this hotfix.
Still, AMD users have another reason to be upset as if they needed one. The hotfix will come, and will come in completely stable form; it just looks like today is not that day. If you already received this update and have experienced technical difficulties, the comment form awaits.

When AMD’s Bulldozer processors arrived, they were unable to best Intel’s fastest at most tasks. A number of users held out hope for Bulldozer; however, as it was discovered that Microsoft’s Windows 7 operating system was not optimized to take advantage of the multi-threaded execution scheduling engine. While MS has implemented this optimization in the Windows 8 kernel, the current stable release has been without a fix until recently. The fix in question is available for Windows 7 and Windows Server 2008 R2 and can be downloaded here. It should be noted that service pack 1 is a pre-requisite to this hot-fix.
Conservatively, previous indications suggested such a fix would add a 5 % to 10 % performance boost in multi-threaded applications. That number is based on the estimates from around the web from people comparing benchmarks between Windows 7 and Windows 8 Developer Preview. If you are running a Bulldozer processor in your machine, be sure to apply this update and let us know how performance improves.

NVIDIA lays as the current front-runner for the “Last Year’s Best Decision, This Year” award. You may remember our coverage last June of the AMD Fusion Developer Summit; industry members such as ARM, Microsoft, and of course AMD discussed the potential of utilizing specialized processors and developing on open platforms such as OpenCL and Microsoft’s announced C++ AMP. Do you know what would have been an amazing announcement for AFDS to stomp OpenCL and C++ AMP? That NVIDIA would open up CUDA. Know what announcement missed that bus by a whole half a year? NVIDIA will open up CUDA.
Your platform pooh-pooh? Bear a CUDA.
While I just harassed NVIDIA for their timing, it might not be too late. CUDA is still a powerhouse of a GPGPU platform with substantial software support from absolute mammoth software packages such as Adobe Creative Suite to smaller projects like KGPU. With the open sourcing of the CUDA compiler, NVIDIA is also permitting manufacturers like AMD and even Intel to support CUDA with their GPUs, x86 CPUs, and other processing units. While I am excited at this outcome, I am still somewhat confused about NVIDIA’s timing: they are just a little late to open up and crush the market, and they seem quite abrupt if they originally intended CUDA to survive as a forever-proprietary computing platform.
The Low Cost Sandy Bridge-E
In the conclusion to my original story looking at the performance characteristics of the Sandy Bridge-E platform, I wrote this:
I am most interested in the Core i7-3930K (as I think most of you will be), but we are going to have to wait a bit to see if we can get performance and power results for that part.
Well good readers, I am here with that information! After getting my hands on the Core i7-3930K processor that makes up the other 50% of the available options for the X79 chipset motherboards, I can definitively say that THIS is the processor you want. Unless you are crazy-go-nuts rich.
With a clock speed only about 2.5% lower than its bigger brother yet a price that is 44% lower, the LGA2011 socket definitely has its enthusiast favorite.
The Sandy Bridge-E Summary
I am not going to bother reprinting everything that we discussed about the new Sandy Bridge-E processor architecture, the X79 chipset and platform changes here though if you haven't read about them before today, you should definitely take a look at my earlier article.
Here is a quicker summary:
The answer might surprise you, but truthfully not a whole lot has changed. In fact, from a purely architectural stand point (when looking at the x86 processor cores), Sandy Bridge-E looks essentially identical to the cores found in currently available Sandy Bridge CPUs. You will see the same benefits of the additional AVX instruction set in applications that take advantage of it, a shared L3 cache that exists between all of the cores for data coherency and the ring bus introduced with Sandy Bridge is still there to move data between the cores, cache and uncore sections of the die.
Turbo Boost technology makes a return here as well with the updated 2.0 version in full effect - there are more steppings in scalability on this part than on the Nehalem or Westmere CPUs.

Our collection of videos comparing the AMD A8-3850 Llano APU to the Sandy Bridge-based Core i3-2105 have been very popular. We thought we would wrap up 2011 with one final video that looks at the integrated graphics solutions on both processors in five of the top games released in 2011. Here is what and how we compared them:
- Batman: Arkham City - 1920x1080 - Low
- Portal 2 - 1920x1080 - Very High
- Battlefield 3 - 1366x768 - Low
- Skyrim - 1920x1080 - Low
- Modern Warfare 3 - 1920x1080 - High
Not to give away the secret but...

Good news for those of you who have been waiting to upgrade in the hopes that Ivy Bridge will be arriving on time. It seems your patience has paid off but you will have to wait a while longer before you can get your hands on Intel's next tick. You can look forward to more PCIe 3.0 lanes, just like those who've jumped onto the new Sandy Bridge E chips and a bump on the GPU portion of the chip. X-bit Labs doesn't have any pricing for the new chips, but they do list all of the models you will be able to buy. One thing you should note are the impressive TDPs, they may not count as low power CPUs but they're certainly lower than other Intel and AMD chips currently on the market.
"Intel Corp. has notified its partners about its decision to introduce of its next-generation code-named Ivy Bridge processors in the second quarter of 2012. Previously the company planned to release the Core i 3000-series central processing units (CPUs) for desktops in March - April timeframe, which left a possibility to unveil the chips in the first quarter."
