The future of mobile CPUs, part 1: Today’s fork in the road | Ars Technica
2013 may be a big year for the evolution of smartphones and tablets.
Mobile computing's rise from niche market to the mainstream is among the most significant technological trends in our lifetimes. And to a large extent, it's been driven by the bounty of Moore’s Law—the rule that transistor density doubles every 24 months. Initially, most mobile devices relied on highly specialized hardware to meet stringent power and size budgets. But with so many transistors available, devices inevitably grew general-purpose capabilities. Most likely, that wasn't even the real motivation. The initial desire was probably to reduce costs by creating a more flexible software ecosystem with better re-use and faster time to market. As such, the first smartphones were very much a novelty, and it took many years before the world realized the potential of such devices. Apple played a major role by creating innovative smartphones that consumers craved and quickly adopted.
To some extent, this is where we still stand today. Smartphones are still (relatively) expensive and primarily interesting to the developed world. But over the next 10 years, this too will change. As Moore’s Law rolls on, the cost of a low-end smartphone will decline. At some point, the incremental cost will be quite minimal and many feature phones of today will be supplanted by smartphones. A $650 unsubsidized phone is well beyond the reach of most of the world compared to a $20 feature phone, but a $30 to $40 smartphone would naturally be very popular.
In this grand progression, 2013 will certainly be a significant milestone for mobile devices, smartphones and beyond. It's likely to be the first year in which tablets out-ship notebooks in the US. And in the coming years, this will lead to a confluence of high-end tablets and ultra-mobile notebooks as the world figures out how these devices co-exist, blend, hybridize, and/or merge.
Against this backdrop, in this two-part series, we'll explore the major trends and evolution for mobile SoCs. More importantly, we'll look to where the major vendors are likely going in the next several years.
Tablet and phone divergence
While phones and tablets are mobile devices that often share a great deal of software, it's becoming increasingly clear the two are very different products. These two markets have started to diverge and will continue doing so over time.
From a technical perspective, smartphones are far more compact and power constrained. Smartphone SoCs are limited to around 1W, both by batteries and by thermal dissipation. The raison d’etre of a smartphone is connectivity, so a cellular modem is an absolute necessity. For the cost sensitive-models that make up the vast majority of the market, the modem is integrated into the SoC itself. High-end designs favor discrete modems with a greater power budget instead. The main smartphone OSes today are iOS and Android, though Windows is beginning to make an appearance (perhaps with Linux or BlackBerry on the horizon). Just as importantly, phone vendors like HTC must pass government certification and win the approval of carriers. There is very much a walled-garden aspect, where carriers control which devices can be attached to their networks, and in some cases devices can only be sold through a certain carrier. The business model places consumers quite far removed from the actual hardware.
In contrast, tablets are far more akin to the PC both technically and economically. The power budget for tablet SoCs is much greater, up to 4W for a passively cooled device and as high as 7-8W for systems with fans. This alone means there is a much wider range of tablet designs than smartphones. Moreover, the default connectivity for tablets is Wi-Fi rather than a cellular modem. The vast majority of tablets do not have cellular modems, and even fewer customers actually purchase a wireless data plan. As a result, cellular modems are almost always optional discrete components of the platform. The software ecosystem is relatively similar, with Microsoft, Apple, and Google OSes available. Because tablets eschew cellular modems, the time to market is faster, and they are much more commonly sold directly to consumers rather than through carriers. In terms of usage models, tablets are much more PC-like, with reasonable-sized screens that make games and media more attractive.
Looking forward, these distinctions will likely become more pronounced. Many tablets today use high-end smartphone SoCs, but the difference in power targets and expected performance is quite large. As the markets grow in volume, SoCs will inevitably bifurcate to focus on one market or the other. Even today, Apple is doing so, with the A6 for phones and the larger A6X for tablets. Other vendors may need to wait a few years to have the requisite volume, but eventually the two markets will be clearly separate.
Horizontal business model evolution
Another aspect of the mobile device market that is currently in flux and likely to change in the coming years is the business model for the chip and system vendors. Currently, Apple is the only company truly pursuing a vertically integrated model, where all phones and tablets are based on Apple’s own SoC designs and iOS. The tight integration between hardware and software has been a huge boon for Apple, and it has yielded superb products.
Samsung is one of the few others companies that takes a vertically integrated approach to phones and tablets, although in truth its strategy seems to be ambivalent on that point. Unlike Apple, Samsung’s SoCs are readily available to third parties, and some Samsung devices, such as the S7562 Galaxy S Duos, use SoCs from competitors. More recently though, there has been a trend of Samsung devices using Samsung SoCs, at least for the premier products. For the moment, Samsung’s approach is best characterized as a hybrid, particularly as the company lacks a bespoke OS.
The rest of the major SoC vendors (e.g., Intel, Qualcomm, Nvidia, TI, Mediatek, etc.) have stayed pretty far away from actual mobile devices. These companies tend to focus on horizontal business models that avoid competing with customers or suppliers.
In the long term, mobile devices are likely to evolve similarly to the PC and favor a horizontal business model. The real advantage is one of flexibility; as costs drop and the market expands, it will be increasingly necessary for vendors like HTC to offer a wide range of phones based on radically different SoCs. While a vertically integrated company like Apple can focus and maintain leadership in a specific (and highly lucrative) niche, it would be very difficult to expand in many growing areas of the market. The differences between an iPhone 6 and a $20 feature phone are tremendous and would be very difficult for a single company to bridge.
However, SoC vendors will attempt to reap the benefits of vertical integration by providing complete reference platforms to OEMs. Conceptually, this is a form of "optional" system integration, where the phone vendor or carrier can get the entire platform from the SoC supplier. This has the principal advantages of reducing time to market while also providing a baseline quality and experience for consumers. Currently, this approach has mostly been tested in emerging markets, but it's likely to become more common over time. There is a crucial distinction between reference platforms and vertical integration. Namely, OEMs can always choose to customize a platform to differentiate, and the SoC vendor avoids dealing with consumers directly. Typically, most of the customization is in terms of software on top of a base operating system.
Quote:Moreover, that will make the transition to a 10nm node even more difficult, as the foundries will have to move from 20nm interconnects to 10nm interconnects and skip a generation.The advances in technology lately allowing components on such a small scale to even be envisioned, much less planned for, are truly amazing.
Off topic: show
I present the first generation 'non-technical' rock:
I don't think your horizontal market development theory is supported by facts. Samsung and Apple are more vertically oriented than their competition, for starters. I know this article is narrowly focused on the hardware, but MS and Intel getting into hardware, Amazon getting into hardware, Google buying Moto, this is all vertical integration. How can you support the idea that this trend will be reversed with no real justification? I'm sure mobile chips will continue to specialize, but I don't think this means what you think it means. Automobile companies started making their own engines and with rare exceptions, never went back to being more horizontal. Same with retail and their store brands. Same with cloud companies and their servers. Same with mobile companies and their OSs. The horizontal market of PCs created by long-lasting standards and loose hegemony is the exception, not the norm.
Why wouldn't the foundries be able close the process gap with Intel? Is it a matter of money? Scale?
I'm not so sure about several things:1- Moore's law's relevance. Moore's Law is about ICs. ICs are not as big a part of mobile computers as they are of desktops, even of laptops: screens, batteries, radios are a huge part of tablets' and phones' costs, as opposed to the bare SoC + RAM.2- The tablet vs phone dichotomy. For some reason (probably price insensitivity due to subsidies), Phones have a tendency to be more powerful than Tablets, ie phone SoCs are more than good enough for tablets. Since the OS and peripherals are the same, it makes more sense to design and build just one type of SoC, and just disable the phone-modem part of it (even the other radios are still required: BT, Wifi, GPS...), same as Intel disable cache and cores for their entry-level CPUs. Once you're fabbing a SoC, it makes more sense to make more of the same than to setup a separate run of a cut-down SoC on an older process, unless volumes are huge. We might still be getting previous-generation, well amortized SoCs in cheaper tablets, though.3- On the contrary, I see a tablet and phone convergence (the ugly phablet). I'm patiently waiting for the new 6"+ phones to replace my Nook Color and Galaxy Note 1 with a single device.4- The advantage of diversity ? Software is becoming ever more important than hardware. Multiplying SoCs means multiplying product development costs, making support and updates more difficult... Again, unless volumes are huge, OEMs are probaly better off going the way of the car industry and using modular "platforms" housed in different chassis with various screen sizes, keyboards, radios, digitizers...I'm wondering why the "single device" trend does not figure in your analysis. Is it stillborn ? Does it have no impact nor dependency on/with SoCs ?
Samsung has its own bespoke OS: Bada and it is used on an extensive line of devices. I think there are numbers somewhere that it outsold Windows Phone 7 for a time.

SoC? System on a Chip I guess?
You're way off on the Moore's Law/cost of smartphones point. The processors used in today's high-end smartphones are already cheap, around $25. And there are less expensive options if you want a lower end product. In fact, the hardware in the whole smartphone is relatively cheap. Analyst's estimate the Z10's materials cost around $160, the iPhone 5 around $140. They're using expensive glass and metals, then there's the battery, memory, etc. which means the processor is a small factor of the cost.And then there's the jump from $140 in materials to the unsubsidized costs. The reason these phones cost $650 is because of the high margins these companies are able to get and the high cost of hardware design and/or software development. But the point is that making the processors 4 times better/cheaper isn't going to change the economics of the smartphone. What will change the economics is commoditized designs and software and cheaper materials all around. Then you'll have a $50 smartphone that's decent.

The margins for desktop and server processors is huge because a) the whole product is expensive so $200 to $1000 for the chip is acceptable, and b) Intel has huge advantages in that space and little competition.So Intel can afford to do the R&D to stay ahead of the curve and keep their position. When your smartphone chip sells for $25 you can't do the R&D to leapfrog a company that sells Xeons for $1000 and Core i5's for $200.
I am happy to see Kanter here at Ars, I like his writing and he maintains Real World Tech, where Linus Torvalds often shows up to comment on CPU arch and other interesting topics.

In that situation, can Intel still justify bringing their A-game to a market where products are essentially commoditised and you have processors selling for a only a few dollars each?The lesson from their previous involvement in the DRAM market is that they probably won't want to be involved because there isn't enough money to be made to justify manufacturing phone SoCs on a cutting edge, or near cutting edge process. In that scenario, Intel may not totally abandon the market but they might just stick to manufacturing SoCs on nodes that are a step or two behind the state of the art.

Intel cannot abandon the phone/tablet market. Desktop/laptop sales are stagnating/decreasing and phones/tablets are on the rise. This trend is only going to increase going forward.But you're right, they're going to have use their fabs that are a step or two behind the cutting the edge. But they're going to have to up their game in the tablet space to even be able to do that.

If Intel can stay ahead in process design - which this article seems to indicate - they should have a major advantage. All else being equal a 14nm chip should be significantly faster and more efficient than the same chip at 22nm. Add in the fact that yields increase geometrically - you can fit a lot more 14nm chips on a given wafer size vs 22nm (or 32nm for the other manufacturers.) and you have a very appealing proposition. And then add in the fact that Intel actually has a pretty good graphics stack and IP. It's not a sure thing by any means, but I suspect ARM may have just prodded a sleeping giant.edit: Also worth noting, Intel, TSMC, and Samsung are the only manufacturers who are building out 450nm wafers. This will increase yields dramatically. Of course Samsung and TSMC will build ARM out, but it definitely puts quite a bit of pressure on all other manufacturers. As the article mentions Intel and Samsung are the only ones who control production top to bottom, and Samsung must share some of the benefits with ARM.
As someone who has worked in the semiconductor industry for longer than contemporary fanboys have existed, I'm getting a bit fed-up seeing many of these articles which rewrite history with analyses distorted by the lens of the contemporary Apple or Samsung fanboy.The mobile industry moved to horizontal integration a long time ago. Better indicators than these odd contemporary obsessions with the relatively non-innovative Samsung and Apple where when Motorola spun out its semiconductor division as Freescale, Nokia stopped making it's own custom designs with TI and ST, and Ericsson spun out it's Ericsson Mobile Platforms division and formed ST-Ericsson with ST.The true innovation in the mobile market was done a decade or more ago mainly by Moto/Nokia/Ericsson/TI/Qualcomm, and Samsung and Apple had little to do with it. Under the hood most stuff has been on a simple linear evolutionary path by the SoC providers since then. The phone manufacturers have then mainly been simply sticking these off-the-shelf SoCs (and their included low-level software stacks) in a box, a job made all the easier with the SoC manufacturer collaboration providing the bulk of the work for the AOSP.

Most tech writing in this area is atrocious. This piece is one of the few well informed articles I've read in a long time.

But they're going to have to up their game in the tablet space to even be able to do that.Actually, that trend will not simply keep increasing going forward. The reason desktop/laptop sales are stagnating/decreasing is due to the fact that most people already have one and therefore don't need to buy another one. The exact same thing will happen with tablets as well. Sales are increasing now because people without tablets are buying them. When most people already own a tablet, they won't be buying a new one every year and therefore sales will stagnate/decrease.The PC market is saturated and in a couple of years, the tablet market will be saturated too. Basically, in order to increase sales in a saturated market, you need to increase the population growth or decrease the longevity of the product.
gypsumfantastic wrote:Why wouldn't the foundries be able close the process gap with Intel? Is it a matter of money? Scale?Probably a mix of a lot of things. One big thing was during this recession, Intel was the ONLY fab company that didn't scale back their R&D. That alone gave Intel a large advantage.Intel has almost always been ahead. One of the reasons could be that Intel works with much higher margins than many of the commodity companies like Samsung and TSMC.Outside of the P4 flop and some of the monopolistic abuses, Intel has typically been selling to high end customers that are willing to pay a premium for "the best".Intel has a large benefit of having a relatively "good name" when it comes to CPUs, so they can effectively charge a brand-name premium.I'm sure there are other reasons, and probably better reasons, but these are the main ones that I think of.

I think the assumption is that, as you say, the tablet market will saturate, with people just replacing existing ones, but the desktop/laptop market could decrease much farther than that, if most people stop replacing them at all. I'm not sure of the likelihood of that, but I think that's where this idea comes from.

Apple once again is dictating the performance in the mobile industry. Nice to see others being able to keep the pace, as well.

Doesn't change the fact that cars would probably have been an asterisk in the history books under "toys for rich people" if it weren't for him.The same applies to to mobile computing for Apple, Samsung, et al.

If the SoC market becomes increasingly commoditised, there isn't going to be the money to justify making them in a state of the art fab.Remember that one of the big selling points of Itanium was that it would make use of process advantages that were effectively paid for by the mainstream x86 market. That didn't quite work out in practice and Itanium processors were often well behind Xeons in process technology.

If we see a race to the bottom where price is the dominant motivator behind purchases, then a high performance SoC will struggle to make its mark.

My point is that the hard electrical engineering, mathematics, DSP, semiconductor physics/chemistry, RF engineering, analogue design, CAD etc. that make modern telecommunications possible has very little to do with the fashion companies who consumers (and unfortunately much of the tech media) associate with it and give the credit (though in this respect Samsung does deserve a bit more credit for their work on NAND flash and displays). The industry simply would not exist TODAY without the overwhelming horizontal integration that already dominates.
Quote:In the long term, mobile devices are likely to evolve similarly to the PC and favor a horizontal business model. The real advantage is one of flexibility; as costs drop and the market expands, it will be increasingly necessary for vendors like HTC to offer a wide range of phones based on radically different SoCs. You don't mention in the article that each SoC necessarily requires a bit of parallel dev work unlike the PC. In the PC world there is a standard BIOS and HW architecture that allows for pluggable designs. On a highly integrated SoC this is untrue. HTC suffers because it has to support radically different SoCs, their drivers and boot loaders, etc. Quote:While a vertically integrated company like Apple can focus and maintain leadership in a specific (and highly lucrative) niche, it would be very difficult to expand in many growing areas of the market. The differences between an iPhone 6 and a $20 feature phone are tremendous and would be very difficult for a single company to bridge.It's only difficult because Apple chooses to ignore that market, not because they can't. If they can release a $99 Apple TV, they can surely cobble together a $20 feature phone if they chose to eschew 8GB of NAND, BT, WiFi, a specialized dock connector, LTE, and their specialized processors. In other words, build the equivalent of an iPod shuffle with a horrible screen and no OS to speak of.

All those companies you've mentioned have just been working off Acorn and Apple's pioneering work. Now, Apple is back at it again, very successfully, and all the companies you mentioned that produce chips with ARM IP in them are licensing them from the company Acorn and Apple formed—ARM.Of course I realise ARM IP has indeed been a major driving factor too (though only one if several architectures before ARM became dominant), though I see ARM's influence on the mobile industry as having nothing to do with modern day Apple and only one piece of the puzzle. My point is that the hard electrical engineering, mathematics, DSP, semiconductor physics/chemistry, RF engineering, analogue design,etc. that make modern telecommunications possible has very little to do with the fashion companies who consumers (and unfortunately much of the tech media) associate with it and give the credit (though in this respect Samsung does deserve a bit more credit for their work on NAND flash and displays). The industry simply would not exist TODAY without the overwhelming horizontal integration that already dominates.Yes the efforts of these companies getting cellular communications standardized were immense. And the technology matured. And then they didn't do much with it. It took some youngin's to look at the problem fresh and add the UI that make today's smartphones work. As we have all seen, the moment your technology has matured is the moment you are screwed because someone else now has the opportunity to look at it as a black box and make something new. Each of those manufacturers knew that smartphones would eventually be awesome, but none of them had the UI and software design to make a truly breakout product. Imagine if Motorola would have been smart enough to buy the Android guys instead of Google. Instead, Google bought a bunch of patents on that cellular black box to try to defend it's platform.And when you think about it, which consumes more man years of engineering effort per year at this point.... iterating that cellular black box or developing the OS, services and apps that power today's smartphones?
Intel had better decide that they are competing in this space "for real", or they are screwed. They've already let the Atom languish for five years, during which ARM has completely caught up in performance.Just like Tim Cook said, if you don't cannibalize your own markets someone else will do it for you.Whether Intel will embrace that concept in time remains to be seen. Personally, I hope they don't; if Intel transforms into a chipless Fab company (like TSMC) everyone benefits.
I still think Samsung has the advantage long term because they have both the SOC and the memory products. As mentioned in the article, TSV's (Through Silicon Via's) are going to be quite a disruption. Today, people normally stack an LPDDR2 package on top of their SOC package (POP or Package On Package). Within the LPDDR2 package, you could have a stack of DRAM die typically with wire bonding connecting the die within the package.Once you more to TSV's, you can have a LOT more connections between the SOC and its DRAM's. While this is being standardized through JEDEC (http://www.jedec.org/category/technolog ... a/3d-ics-0), Samsung has all the pieces in house to do whatever they want. You could see a 512 bit or higher bus from the SOC to the memory. The trick is that the memory and the SOC need to line up with each other when you stack them. This gives Samsung an inherent advantage.This isn't just going to impact mobile either. Take a look at that JEDEC link. It also lists High Bandwidth Memory (HBM). This is a 1024 bit bus that provides 128GBytes/s to 256GBytes/s of bandwidth to a stack of up to 8 DRAM's. Here is your processor that includes 8-16 cores and 4GBytes of really, really, fast DRAM... No DIMMs required. How many of them do you want in your server rack?If I was Intel or Apple, I would be thinking seriously about making some investments in Micron to guarantee they make some compelling DRAM's to integrate with their SOC's and processors... otherwise Samsung is going to blow them out of the water on bandwidth.

The Z2760 is even 32nm vs 28nm of the latest Krait and A15 chips.But that's all changing with Atom moving to the tick tock schedule this year. It wouldn't even surprise me to see Apple move to Intel chips for IOS.And I don't see how Intel moving to a chipless Fab company would help everyone. It certainly wouldn't help Intel.

This trend is only going to increase going forward.But you're right, they're going to have use their fabs that are a step or two behind the cutting the edge. But they're going to have to up their game in the tablet space to even be able to do that.Actually, that trend will not simply keep increasing going forward. The reason desktop/laptop sales are stagnating/decreasing is due to the fact that most people already have one and therefore don't need to buy another one. The exact same thing will happen with tablets as well. Sales are increasing now because people without tablets are buying them. When most people already own a tablet, they won't be buying a new one every year and therefore sales will stagnate/decrease.The PC market is saturated and in a couple of years, the tablet market will be saturated too. Basically, in order to increase sales in a saturated market, you need to increase the population growth or decrease the longevity of the product.Yes and no. I'm not sure the tablet market will saturate in a "couple of years." It may be more like 5 years. But that's a quibble.Here's the real issue. Right now Apple wants you to own an iPhone AND iPad AND Macbook AND iWatch AND Apple TV. Microsoft, OTOH, is making the Surface so that you could ditch your laptop and just use a Surface. Not everyone, but some people.If 5 years from now, we're in a world where a significant number of people use a Surface-type device instead of a laptop, then the PC market is going to contract significantly. Maybe some of the tablet-like devices will use moderately expensive Intel chips, but some of them are going to use cheaper chips.

Last I checked they still made memory...and processors/GPUs.
