What's Different This Time Around: Google & A Sweet Reference Platform

Intel has been talking about getting into smartphones for a couple of years now, but thus far it hasn't been able to secure a single design or partnership that that resulted in a product actually coming to market. This time around, things are different. The major change? Focus, and Google.

Intel originally had ambitions of enabling its own mobile OS with the help of Nokia (Moblin/MeeGo). Intel also wanted to support Android as well, however its attention was clearly more focused on the Moblin/MeeGo effort. Similar to the wake up call that pushed NVIDIA to focus exclusively on Android, Intel has now done the same.

At IDF last year Intel and Google announced a partnership and the intention to bring all future versions of Android, starting with Gingerbread, to x86. Since then Intel has ramped up the software engineering engine, going into the Android source code (Gingerbread, Honeycomb and now ICS) and fixing bugs. Intel's goal is to deliver the most stable version of Android as a result of its efforts. Intel is also submitting its changes upstream to the AOSP, which should help improve the Android experience even on ARM platforms.

 

 

Under the leadership of Mike Bell (formerly of Apple and Palm), Intel has also created an extremely polished Medfield reference design. This is the same design shown off at IDF last year (apparently there's an even thinner one floating around somewhere), but what separates it from other reference designs we've seen from SoC vendors is that the Medfield reference platform was designed to be a polished phone that could theoretically be rebranded and resold.

Intel knew the onus was on itself to prove that Medfield, Atom and even just x86 was power efficient enough to be delivered in a compelling form factor with competitive battery life. Paul Otellini gave Mike carte blanche access to any of Intel's resources. Instead of having to work with existing Intel groups, Mike was allowed to assemble his dream team of engineers. The team Mike built is what he felt he needed to not only bring Medfield to market, but also to build the a first class Atom based smartphone.

The result is this:

 

Internally it features Intel's own XMM 6260 HSPA+ modem. Intel claims LTE is on the way although there's no ETA on that.

WiFi in the reference design is provided by TI's 1283 controller. Intel's wireless team does not have a a WiFi solution that's low power enough to work in a smartphone, although after the recent restructuring the team has now been tasked with building an ultra low power solution that can.

 

The display is a somewhat unusual 1024 x 600 panel, with support for 1080p30 (and 1080i60) output via HDMI. The SoC specs are identical to what I've already discussed: 1.6GHz max CPU clock and a 400MHz GPU clock.

The reference platform is not only smartphone sized, but Intel has built its own qualification labs that mirror those of the carriers to ensure quality and convince its customers of the platform's legitimacy. In essence, Intel has built its own miniature smartphone design and test center.

The Medfield reference platform is available for use by any of Intel's customers, and indeed that's what's already happening. Lenovo's K800 is based on a modified version of Intel's reference platform, and I wouldn't be surprised if more aren't on the way.

All of this sounds a lot like Intel's efforts in the motherboard space over a decade ago where it started providing motherboard manufacturers with reference designs that they could modify if they desired. The effort helped significantly reduce time to market and allowed the motherboard makers to focus more on specializing on what they were good at.

The Medfield reference platform is designed to do the very same for smartphones. Intel wants to provide its partners with a well designed, stable smartphone platform. If they choose to use it, they can shave off a significant amount of development time and spend more of their time on software or simply bring a good reference phone to market in a quick fashion. I'm not entirely sure I've seen many players in the Android space that are actually all that great at software development, but Intel believes anything that shortens time to market will be appreciated.

I asked Intel if it has any plans to offer the reference platform unlocked, direct to customers. Unfortunately the answer at this point is still no. I suspect that Intel is more interested in building its customer base rather than circumventing it.

    Oh, and Intel's first step into the smartphone market was Moorestown. Just because almost no one used it doesn't mean that it wasn't an attempt and that we should congratulate Medfield as a first try. Reply

    ARM vendors will be RELEASING chips on 32nm HK and 28nm 4/months before Medfield hits anyware but China.

    The above tests are misleading, but desite that they are impressive as i thought they would be a lot further away than that.

    Medfield = tegra 2 class, you have to remember that the above chips are clocked alot lower than 1.66ghz and they are single thread benchmarks.
    regards to power consumption,as stated they are 45nm designs, when 28&32nm big_LITTLE arrives in a couple of months,with on die 4g, we are in another territory altogether.

    When silvermont arrives it will fair against 28nmHK QUAD CORE KRAITS running at 2.5ghz and above....cant see Intel smashing that, but long term if they can be competitive then they may win due to resouces.

    Yeah I always found the comments on x86 phones hillarious because of the ARM loving going on. I mean, it is an instruction set. Stop being an instruction set fanboy people.

    I've said from the beginning that Intel is not a company to expect to lay down. They just have way too many smart people, money, and by far the best fab in the industry to expect them not to be able to compete.

    I'm no Intel fanboy (and certainly not x86 I mean who can love an instruction set) but they have been killing it in all sectors lately. Even their GPUs don't suck as bad as before.

    I am impressed.

    even AMD doesn't whine about being at least a couple years behind Intel's process technology and that fact has hurt them big time. In the end, the consumer doesn't care "why" Intel has a strategic advantage with their technology it'll make them successful in smartphones Reply

    Dark_Archonis, Does not matter that the Medfield processor is based on 5 year old hardware design. ARM processors uses hardwired microcode while 80x86 processors uses software microcode. There is a difference how fast and how easy it is to design and optimize a processor with either of these ways. Intel can take a ten year old model and optimize the microcode while ARM will have to keep on designing new models in hardware to push out higher performing processors.

    The number one question, will the mobile industry take this processor even though software have to be rewritten. Sure Intel said that about 75% of Android apps can be used. Sure 90% of apps can be used if emulation is used. Mac users knows all to well that Rosetta slows down PowerPC software on an x86 processor because of the emulation.

    Now why can Intel can fix their five year old Atom processor to be crammed into a smartphone is most of Intel's money goes into R&D. ARM does not have that money to go into R&D. If ARM did, Intel will have a very, very serious competitor even though ARM is an engine that runs on a completely different fuel. So the comparison of the Medfield processor from Intel and ARM Cortex A9 is like comparing apples to oranges.

    ARM processors suits niche markets better than x86 processors. x86 processors suits a general purpose setup. This means Intel will have to be ready to make dramatic changes to Medfield to suit many different configurations. Intel's history for this type of business is poor or is not capable because of the tight control of the license. ARM succeeds in a market the requires many different changes thanks to its lighter control of the license. ARM processors are like lego blocks and x86 processors are like as-is.

    I know what you're saying but I really feel you're wrong on one point and need clarification on another.

    First, assuming Intel or x86 processors are not built with a (lego) block architecture is a fallacy that needs to stop right now. There's no reason x86 processors and SOCs can't be built this way and Penwell is the first example of this. I think you'll see Intel reusing and sharing a whole lot more IP blocks internally up and down the vertical stack because of this move into phones/tablets.

    Second, its starting to get a little old always referring to ARM, especially how you do with respect to RnD. Its not ARM spending those dollars, its four or five discrete companies: Qualcomm, TI, nVidia, Samsung, etc. ARM sells licenses...it doesn't generally give a rip how many of its chips are sold unless the license fee is predicated on volume. Its up to the chip designers to compete with Intel, not ARM.

    Partly true, ARM does spend R&D of course, else there wouldn't be a Cortex/Mali reference design to buy..let alone any interconnects/future ISAs Reply

    You did not read my comment correctly. I said that ARM processors are like legos while Intel or x86 is as-is. The problem with Intel's Medfield is Intel's business model. Their model is as-is, so companies that want to use this processor will have to add the components outside of this processor. In ARM case, the components can be added in the chip which does not take any space on the motherboard. When components are placed outside of the processor, the space that could have been a bigger battery will be taken up by additional components. The companies that will use the Medfield is smartphone and tablet brands like Lenovo and others.

    ARM makes the processor models while Qualcomm, TI, nVidia, Samsung, and others integrates them in their designs and with other technologies that these companies have created themselves. The companies that takes these processors and put them in their smartphones and tablets are LG, HTC, Nokia, ASUS, Samsung and others.

    IMHO, ARM based smartphones and tablets will be cheaper than Intel based because there is least amount of effort for designing ARM based versions. Sure you can keep on supporting and hoping that Intel looks good in the smartphones and tablets, but the as-is business model is going to hurt Intel.

    Only a few percent of instructions executed on Atom even use microcode at all. It's not so much that ARM CPUs use "hardwired microcode", it's more that they don't have instructions that are complex enough to merit microcode at all. There are a few that have some sequencing in the decoder, mainly the load/store multiple instructions, but their mapping is really straightforward; there isn't any real element of being able to "optimize" them in the same uarch.

    Most x86 instructions that are implemented as microcode on Atom are legacy instructions that made sense 30 years ago but don't today, either due to changes in software requirements (see BSD numeric instructions for a good example of this..) or changes in what is efficient to implement directly (see loop instruction). For a lot of these instructions you're better off doing it using simpler non-microcoded instructions. So Intel optimizing their microcode is worth mentioning (some of the instructions looked WAY slower than they should have been, going by Agner Fog's timings) but not really some massive competitive edge against ARM. It'll probably barely register as a change on any benchmarks. Hopefully Intel will make the optimizations available for the older Atoms too (the microcode can be soft-patched) and then you can see for yourself.

    How is "too little too late" going to help Intel? By the time products with this trash flock to market, it'll be up against A15 and look like the thing from yesteryear it really is.. Reply
