Apple is da bomb! Vulnerability found in battery circuitry

Subject: Editorial, General Tech | July 26, 2011 - 02:24 AM |
Tagged: Malware, apple

Okay, so the title is more joke than anything else but security researcher Charlie “Safari Charlie” Miller discovered a vulnerability in Apple devices, sort of. This exploit, which appears to not actually be a security flaw and rather just an over-permissive design, allows an attacker to gain access to your battery control using one of two static company-wide passwords. Charlie has discovered many exploits in the past several years on the OSX and iOS platforms. One of the most high profile attacks he discovered involved a data-execution vulnerability in the iPhone’s SMS handling: under certain conditions your iPhone could potentially confuse inbound text messages as code and run it with high permissions.

So what does having the ability to write to a laptop’s battery firmware mean? Firstly, remember the old advice of “Get a virus? Reinstall your OS!”? Well assuming you actually can perform a clean install without ridiculous hacking (thanks Lion) the battery controller can simply re-infect you if the attacker knows an exploit for your version of OSX. But how does the attacker know your current version of OSX? Well if you are installing from an optical disk they just need to know a Snow Leopard RTM exploit; unless of course you extract Lion from the Mac App Store and clean install using it – assuming the attacker does not know an exploit for Lion or simply just infects the reinstall media if you created it from the infected computer. True, malware is about money so it is highly unlikely that an attacker would go for that narrow of a market of Mac users (already a narrow-enough market to begin with) but the security risk is there if for some reason you are a tempting enough target to spear-phish. Your only truely secure option is removing the battery while performing the OHHHHHHHH.

You know, while working (very temporarily) on the Queen's University Solar Vehicle project I was told that Lithium cells smell like sweet apples when they rupture. I have never experienced it but if true I find it delightfully ironic.

While that would all require knowledge of other exploits in your operating system, there is a more direct problem. If for some reason someone would like to cause damage against your Apple devices they could use this flaw to simply break your batteries. Charlie has bricked nine batteries in his testing but has not even attempted to see whether it would be possible to over-charge a battery into exploding. While it is possible to force the battery controller to create the proper conditions for an explosion there are other, physical, safe guards in place. Then again, batteries have exploded in the past often making highly entertaining Youtube videos and highly unentertaining FOX news clips.

Overclocking Llano just makes sense, but the RAM not so much

Subject: General Tech | July 25, 2011 - 07:30 PM |
Tagged: llano, ddr3-1866, a8-3850

Most reviewers made a financial decision when pairing RAM to review AMD's new Llano A8-3850 processor.  Most chose 1333MHz DDR3, since when building a low cost PC most users are going to choose the lower cost as opposed to spending half the budget simply on DDR3.  After seeing significant overclocks produced by a variety of testers, The Tech Report thought it would be interesting to see the impact of high speed RAM on the performance of an A8-3850, especially the graphics portion.   As it turns out, the decision to go with lower cost RAM made a lot of sense as the the graphical performance did not benefit from faster RAM.

Phone in your overclocking, MSI Afterburner App for Android

Subject: General Tech, Graphics Cards, Mobile | July 25, 2011 - 06:58 PM |
Tagged: msi, Android

Are you a hardcore PC user who likes to tweak your computer? Naturally there is an app for you. MSI has launched an application for the Android Marketplace this morning to allow users wishing to monitor and overclock their computers the ability to use their Android-powered smartphone or tablet for that purpose through their wireless network. This version allows you to monitor temperature, voltage, fan speed and adjust clock rates, voltages, and fan speeds.

afterburner.jpg

Let's hope Angry Birds doesn't see this: Some systems' power consumptions are pigs!

MSI Afterburner APP has relatively modest requirements: a tablet or smartphone device running Android 1.6 or higher, a system running Windows XP or later with a discrete graphics card, access to a network with wireless access for the Android device to link into, and Afterburner 2.1.0 or later installed on the PC. Setting up your PC is relatively simple once you have Afterburner installed as you just need to run, not even install, an application “Remote Server” that you can download from the MSI website linked to from the Android Marketplace link. While this application is too new to be rated, it is free and thus there is little reason to not simply try it out yourself.

We know where your Bitcoins went

With all the research that Ken did, it turns out that Bitcoin mining will not make you rich overnight and possibly cost you more money to create a bitcoin than you will ever see out of it.  Now, according to a study linked to at Slashdot it seems that one of the big attractions of Bitcoins is not true.  Researchers have found that with enough work and data, Bitcoin purchases are not anonymous.  Anonymity was never a major goal for those who first envisioned Bitcoins but it has been touted as a major feature by those who have been mining and spending coins.  If that is why you are interested in the process of mining maybe it is a better idea to switch to an @home project.

"Researchers from University College Dublin have conducted an analysis of anonymity on Bitcoin, and found it is not inherently anonymous, and that in many cases, users and their transactions can be identified. They use techniques such as context discovery and flow analysis to investigate and visualize an alleged theft of Bitcoins, which, at the time of the theft, had a market value of approximately half a million U.S. dollars."

Intel MLAA: Matrox had the right idea, wrong everything else

Subject: Editorial, General Tech, Graphics Cards, Processors | July 23, 2011 - 12:20 AM |
Tagged: MLAA, Matrox, Intel

Antialiasing is a difficult task for a computer to accomplish in terms of performance and many efforts have been made over the years to minimize the impact while still keeping as much of the visual appeal as possible. The problem with aliasing is that while pixels are the smallest unit of display on a computer monitor, it is large enough for our eye to see it as a distinct unit. You may however have two objects of two different colors partially occupy the same pixel, who wins? In real life, our eye would see the light from both objects hit the same retina nerve (that is not really how it biologically works but close enough) and it would see some blend between the two colors. Intel has released a whitepaper for their attempt at this problem and it resembles a method that Matrox used almost a decade ago.

MatroxAA.jpg

Matrox's antialiasing method.

(Image from Tom's Hardware)

Looking at the problem of antialiasing, you wish to have multiple bits of information dictate the color of a pixel in the event that two objects of different colors both partially occupy the same pixel. The simplest method of doing that is dividing the pixel up into smaller pixels and then crushing them together to an average which is called Super Sampling. This means you are rendering an image 2x, 4x, or even 16x the resolution you are running at. More methods were discovered including just flagging the edges for antialiasing since that is where aliasing occurs. In the early 2000s, Matrox looked at the problem from an entirely different angle: since the edge is what really matters, we can find the shape of the various edges and see how much area of a pixel gets divided up between each object giving an effect they say is equivalent to 16x MSAA for very little cost. The problem with Matrox’s method: it failed with many cases of shadowing and pixelshaders… and came out in the DirectX 9 era. Suffices to say it did not save Matrox as an elite gaming GPU company.

Look familiar?

(Both images from Intel Blog)

Intel’s method of antialiasing again looks at the geometry of the image but instead breaks the edges into L shapes to determine the area they enclose. To keep the performance up they do pipelining between the CPU and GPU which keeps the CPU and GPU constantly filled with the target or neighboring frames. In other words, as the GPU lets the CPU perform MLAA, the GPU is busy preparing and drawing the next frame. Of course when I see technology like this I think two things: will this work on architectures with discrete GPUs and will this introduce extra latency between the rendering code and the gameplay code? I would expect that it must as the frame is not even finished let alone drawn to monitor before you fetch the next set of states to be rendered. The question still exists if that effect will be drowned in the rest of the latencies experienced between synchronizing.

AMD and NVIDIA both have their variants of MLAA, the latter of which being called FXAA by NVIDIA's marketing team. Unlike AMD's method, NVIDIA's method must be programmed into the game engine by the development team requiring a little bit of extra work on the developer's part. That said, FXAA found its way into Duke Nukem Forever as well as the upcoming Battlefield 3 among other games so support is there and older games should be easy enough to just compute properly.

37407.png

The flat line is how much time spent on MLAA itself, just a few milliseconds and constant.

(Image from Intel Blog)

Performance-wise the Intel solution performs ridiculously faster than MSAA, is pretty much scene-independent, and should produce results near the 16x mark due to the precision possible with calculating areas. Speculation about latency between render and game loops aside the implementation looks quite sound and allows users with on-processor graphics to not need to waste precious cycles (especially on GPUs that you would see on-processor) with antialiasing and instead use it more on raising other settings including resolution itself while still avoiding jaggies. Conversely, both AMD and NVIDIA's method run on the GPU which should make a little more sense for them as a discrete GPU should not require as much help as a GPU packed into a CPU.

Could Matrox’s last gasp from the gaming market be Intel’s battle cry?

The biggest mistake you can make, next to admitting you know about computers, is offering tech support to family.   Paying a backyard mechanic in beer, food or both is well ingrained in most peoples mind as is the fact that the repair will not be instantaneous.   Such is not true of the lowly PC tech, not only are you unlikely to be offered anything for your efforts there is usually about a 5 minute time limit for you to finish rebuilding the smoking and infected ruin that once was a loved ones PC.  On the other hand you can't say no to Mom, nor should you go for fancy repairs like you would do for yourself

Not that you can win by keeping things secret of course, nothing will protect you from equipment that shows up dead on your doorstop or works but is just plain recalcitrant.  Sometimes asking for advice before you buy is your best bet, just speculating on unreleased hardware is probably safer.  Even safer would be to just listen to us talk and speculate on hardware in the latest installment of the PC Perspective Podcast ... the last one from the TWiT Cottage.  Next week we should be broadcasting from the new Brick TWiT house.  Then we may be doing something from QuakeCon, don't miss it if you have a chance to go!

 

Bulldozer will be on time, missing CEO or not

Tagged: amd, bulldozer, finance, release

AMD has a lot to happy about today, even if both they and GLOBALFOUNDRIES are one CEO short of a full board.  This time last year AMD was talking up Bulldozer as a product 12 months or more out of market and facing a $43 million loss under “Generally Accepted Accounting Principles”, as Josh explained fully.  Long story short it was money being paid for GF; the unadjusted profit for the quarter was actually $83 million, . This quarter it was a $61 million profit, $70 million non-GAAP, thanks to AMD focusing on keeping the costs down, with a bit of help from the recent release of Llano. 

On the processor side, AMD is pegging the 16-core "Interlagos" Opteron 6200 Bulldozer CPU for servers and the Zambezi FX series will both come out at the same time, at least as far as revenue is concerned.  We may not have them in hand for a while longer than that, but not too long.  Drop by the Register for the full picture.

scroogemcduck.jpg

"The hybrid CPU-GPU chips for mobile PCs gave Advanced Micro Devices some breathing room in the second quarter, but it's going to take continued ramping of these APU processors and an upswing in Opteron server sales to get the company back to the profit levels it should be enjoying during a retooling phase in the IT market – and it looks like AMD and its server partners won't have to wait too much longer."

18,592 Academic Papers Released To Public Via Torrent

Subject: General Tech | July 21, 2011 - 11:29 PM |
Tagged: torrent, tech, networking, jstor

In light of Aaron Swartz’s recent legal trouble involving charges being brought against him for downloading academic papers from the online pay-walled database called JSTOR using MIT’s computer network, a bittorrent user named Greg Maxwell has decided to fight back against publishers who charge for access to academic papers by releasing 18,592 academic papers to the public in a 32.48 gigabyte torrent uploaded to The Pirate Bay.

library.png

Maxwell claims that the torrent consists of documents from the Philosophical Transactions of the Royal Society journal. According to Gigaom, the copyrights on these academic papers have been expired for some time; however, the only way to access these documents have been through the pay-walled JSTOR database where individual articles can cost as much as $19. While Maxwell claims to have gained access to the papers many years prior through legal means (likely through a college or library’s database access), he has been fearful of releasing the documents due to legal repercussions from the journal’s publishers. He claims that the legal troubles that Swartz is facing for (allegedly) downloading the JSTOR library has fueled his passion and changed his mind about not releasing them.

Maxwell justifies the release by stating that the authors and universities do not benefit from their work, and the move to a digital distribution method has yet to coincided with a reduction in prices. In the past the high cost (sometimes paid by the authors) has been such to cover the mechanical process of binding and printing the journals. Maxwell further states that to his knowledge, the money those wishing to verify their facts and learn more from these academic works “serves little significant purpose except to perpetuate dead business models.” The pressure and expectation that authors must publish or face irrelevancy further entrenches the publisher’s business models.

Further, GigaOm quoted Maxwell in stating:

“If I can remove even one dollar of ill-gained income from a poisonous industry which acts to suppress scientific and historic understanding, then whatever personal cost I suffer will be justified . . . it will be one less dollar spent in the war against knowledge. One less dollar spent lobbying for laws that make downloading too many scientific papers a crime.”

Personally, I’m torn on the ethics of the issue. On one hand, these academic papers should be made available for free (or at least at cost of production) to anyone that wants them as they are written for the betterment of humanity and pursuit of knowledge (or at least as a thought provoking final paper). On the other hand, releasing the database via a torrent has it’s own issues. As far as non-violent protests go, this is certainly interesting and likely to get the attention of the publishers and academics. Whether it will cause them to reevaluate their business models; however, is rather doubtful (and unfortunate).

Gmail Now Supports Multiple Calls and Placing Calls On Hold

Subject: General Tech | July 21, 2011 - 08:27 PM |
Tagged: networking, voip, google

The Gmail blog recently showed off a new feature that allows you to put one call on hold while accepting another, a feature that standard phones have had for a long time now. Inside Gmail, you are able to start a call to another computer or a physical phone and then you are free to place this call on hold by hitting the “hold” button. When you wish to return to the call, you simply hit the “Resume” button- just like a normal phone. When a second person calls you, you will be asked to accept or reject it, and if you accept the call the first call will automatically be placed on hold.

multiplecalls.png

According to Google, the call hold feature “works across all call types (voice, video, and phone)” and the only caveat is a limit of two outgoing calls to physical phones can be active at a time. The only feature I see missing from this function is integration with Google Music that would allow me to set up custom hold music to the chagrin to telemarketers and customer support everywhere. After all, it is almost a Friday and everyone would just love to hear some Rebecca Black, right!?

Many gaming keyboards feel the need for glowing keys, LED screens or even fans to cool your palms while you game.  The SteelSeries 6G V2 goes a completely different way to satisfy those who want a good quality keyboard without any extravagant bells or whistle.  It is a mechanical keyboard which can handle 6 simultaneous keypresses over USB and an unlimited amount over PS/2.  The evil Windows key that lives under your keft palm has been replaced with a SteelSeries Key that will activate the sparse media keys sharing space with your function keys.  At $120ish it may be a bit rich for some gamer's blood, Funky Kit recommends it for those who are willing to pay the price.

"Revolutionary designs for keyboards dont exaclty pop up all the time. The old saying "if it isn't broken..." holds true to the basic keyboard design. Sure there are fancy things thrown in there like backlit keys, LCD screens, and macro buttons. But does that really matter for most people? Not really.

Steelseries has taken that if it isn't broken formula, but tweaked it a bit. This particular keyboard, the "6G V2 gaming keyboard" gives a basic design look of a $10 keyboard you can buy at any big retail store but packs some cool stuff under the hood. Read more ahead ..."

Bumpday 7/20/2011: 3D Glasses not available in all areas

Subject: Editorial, General Tech | July 20, 2011 - 06:00 PM |
Tagged: bumpday, 3d

This week LG unveiled their glasses-free 3D LCD display with only a minimal amount of LG employees trying to pet a poorly Photoshopped Formula One race car. 3D is quite heavily promoted lately with the hype machine apparently being fueled by anthropomorphic blue cats and Box Office records. 3D on the PC has been around for much longer, however. NVIDIA and ELSA had support for 3D glasses over a decade ago for 3D effects in games of the time. There really has not really been much said about 3D between then and the rush of publicity now so I guess it is time to bump it up in our memory.

Bumpday2.png

This week’s intermission… in the third dimension

In August 2002 the epitome of threads on ATI’s lack of 3D stereoscopic support was born with a simple message: give your greens to the green. Of course whenever you mention one brand over another there immediately becomes a three-way comparison between the market leaders: ATI, nVidia, and Matrox (wha-what!?! Actually another article will be posted soon; an old Matrox technology has a spiritual successor… because the body’s long since dead.) Even back then, however, we had people who bashed 3D technology long before it was cool to dislike 3D technology. Some people like it a lot though, enough to drop down 1600$ on a pair of 3D VR glasses, but no money on an ATI card.

Apple released their latest operating system dubbed OS X Lion today that includes more than 250 new features the company states will make dramatic improvements to how users interact with Apple's entire line of computer systems. The $29.99 upgrade includes several new features like multi-touch gestures, full-screen apps, a new Mission Control section, and a new location for Mac apps called LaunchPad.

Apple expanded OS X's ability to view installed applications through a new program called Launchpad. Launchpad allows users to see all of their apps on one screen gives you instant access to all the apps on your Mac. Previously, loaded apps were viewed in a smaller window and now Launchpad will use all the screen real estate more efficiently to show users all their apps at one time.

OS X Lion also showcases a redesigned Mail program that uses a widescreen view to show message lists in modular sections that are more intuitive to read and use. Another section called Conversations gives users a basic timeline to show threads of messages from specific people. The revamped program also includes search suggestions and search tokens to make finding archived or buried e-mails alot simpler than clicking around for them.

Another interesting feature Apple added is the OS X Lion Server that provides more control over user and administerator permissions versus the previous Server app. This program can basically turn almost any Mac into a basic server with secure options for remotely managing computers running Lion and other iOS devices like iPhones and iPad2s. Server admins can also send updates to all their users wirelessly through push notifications. Apple also made many improvements to the OS's file sharing options and to other programs like Wiki Server, iCal Server and Mail Server.

The OS X Lion upgrade can be purchased from the Mac App Store or online at Apple.com for $29.99. The entire download weighs in at around 3.49GB, which is a pretty significant update that should give many users more flexibility in how their use and interact with their Apple systems.

FPS games have hit the innovation wall? Not so says John Carmack

In a recent interview John Carmack seemed quite annoyed by a question implying that the current generation of first person shooters are all carbon copies of each other.  He picked one of the favourite targets of game critics, Call of Duty, citing the fact that if people were sick of the game and its general game play that it would not sell the way that it does.  He also touched on the cinematic opportunities offered by 3rd person game play; when you watch a movie it is very rare for the director to choose a first person view as that limits their creative choices for effects and environments.  Follow the link from Slashdot for more information.

carmack-flying.jpg

"id Software co-founder John Carmack defended the creativity of first-person shooter games in a recent interview. The legendary programmer, who was a pioneer in the shooter genre with Doom and Quake, said he doesn't like hearing from developers that shooters aren't good because they're not reinventing the wheel. 'I am pretty down on people who take the sort of creative auteurs' perspective. It's like "Oh, we're not being creative." But we're creating value for people — that's our job! It's not to do something that nobody's ever seen before. It's to do something that people love so much they're willing to give us money for... you see some of the indie developers that really take a snooty attitude about this,' he lamented."

Southern Island is ahead of the pack, but it is set to low power for now

Subject: General Tech | July 20, 2011 - 04:25 PM |
Tagged: southern islands, nvidia, gpu, amd, 28nm

Thanks to some information garnered by SemiAccurate we have a very good idea of AMD's release plans for their new GPU family, what we have been referring to as Southern Islands.  The confusion that we felt from AMD's announcement that Southern Island parts would be ready sooner than expected arose from the reported difficulties that TSMC was having with their 28nm HKMG process.  Thankfully someone had a chance to take apart some 28nm TSMC field programmable arrays and inside found a HKMG design modified for lower power states than the original specs.  That doesn't mean cellphone level graphics performance but certainly means that the first GPUs we see from Southern Islands will not be the high end cards.  AMD did the same thing with previous generations of GPUs, so the release schedule is becoming a habit, even if not what would be preferred.

There are other side effects to this choice by AMD and TSMC which are probably going to hurt NVIDIA, who are hoping to get full power Kepler based GPUs out at the beginning of next year.  Since NVIDIA tends towards more aggressive clocks, the experience that TSMC has with what is called the HPL 28nm process will not necessarily help NVIDIA's HKMG 28nm process.  SemiAccurate has more.

chipworks_151433-c_branded.jpg

"The final piece of the TSMC 28nm HKMG process puzzle was put in place at SemiCon last week, it now makes sense. Chipworks got ahold of a Xilinx Kintex-7 FPGA, and it revealed a few secrets on the operating table.

If you recall, AMD is on track to put out Southern Islands chips much earlier than most people, SemiAccurate included, expected, possibly even this quarter. The real question is what process they are going to make it on, the TSMC 40nm SiON or 28nm HKMG? 40nm would be big, hot, and limited, think volcanic island more than Southern, while the 28nm SHP HKMG process wasn’t supposed to be ready until late Q1, best case. The short story is that Southern Islands is very likely not on either one."

One side-effect of splitting a program up into multiple processes is that instructions do not inherently have a specific order. One of the most evident places for that to occur is during a videogame. I am sure most gamers have played a game where the controls just felt sluggish and muddy for some inexplicable reason. While there could be a few problems, one likely cause is that your input is not evaluated for a perceivably large amount of time. Chris Blizzard of Mozilla took on this and other issues with multithreaded applications and wrapped it around the concept of Firefox past, present, and future.

Firefox is getting Beta all the time.

One common misconception is that your input is recognized between each frame, which is untrue: many frames could go by before input affects the events on screen. John Carmack in a recent E3 interview discussed about iD measuring up to 100ms worth of frames occurring before a frame occurred which recognized the user’s command. This is often more permissible for games with slower-paced game design where agility is less relevant; if your character would lose to a Yak in a foot race, turns about as quick as one, and takes a hundred bullets to die: you will not notice that you started to dodge a few milliseconds earlier as you would expect to die in either case. In a web browser it is much less dramatic though the same principle is true: the browser is busy doing its many tasks and cannot waste too much time checking if the user has requested something yet. This aspect of performance, along with random hanging, is considered “responsiveness”. Mozilla targets 50 milliseconds (one-twentieth of a second) as the maximum time before Firefox rechecks its state for changes.

Chris Blizzard goes on to discuss how hardware is mostly advancing on the front of increases in parallelism rather than clock speed and other per-thread advancements. GPGPU was not a topic in the blog post leaving the question for the distant future centered on what a multithreaded DOM would look like – valuing the classical multicore over the still budding many-core architectures. Memory usage and crashing were also addressed though this likely was more to dispel the Firefox stereotype of being a memory hog starting later in the Firefox 2 era.

The GPGPU trail is not Mozilla's roadmap.

The last topic discussed was Sandboxing for security. One advantage of branching off your multiple threads into multiple discrete processes is that you could request that the operating system assign limited rights to individual processes. The concept of limited rights is to prevent one application from exploiting too much permissions for the purpose of forcing your computer to do something undesirable. If you are accepting external data, such as a random website on the internet, you need to make sure that if it can exploit vulnerability in your web browser that it gains as little permission as possible. While it is not a guarantee that external data will be executed with dangerous permission levels: the harder you can make it, the better.

CoolerMaster's new Storm headphones have nothing to do with JK Rowling

Tagged: CoolerMaster Storm Sirus, audio, 5.1 headset

Naming a product Sirus right now might attract an odd crowd, then again maybe it is best that they are using headphones to watch or listen to their favourite series.  CoolerMaster's newest member of the Storm lineup is not a case, mouse or fan, it is a 5.1 surround headset.  One of the more interesting features is that there is only one wire coming from the headset, connecting to a small round controller.  From there you connect to the PC using USB, or preferably, 4 of the analog jacks on the back of your PC.  The controller allows you to adjust the levels of each channel separately, which is a very nice touch.  Unfortunately however Neoseeker adjusted it they couldn't bring it up to audiophile standards, but they have no reservations recommending it for gamers.

"Not one to be left out, Cooler Master enters the PC audio market with a 5.1 surround sound headset of its own that can connect to your audio source via analog jacks or USB port. See how well the Sirius stacks against more specialized headsets in our latest audio review."

Intel and AMD be warned; ARM could grab up to 20% of the laptop market in the next 4 years

Those who ignored Microsoft's announcement that Windows 8 will support ARM processors will perhaps take note of Isuppli's claim that ARM could grab 1 in 5 of the laptops sold by 2015.  The extremely low powers System on a Chip design that they have been selling were at the opposite end of the market from AMD and Intel's X86 chips, but with the rise of the APU the market has undergone a fundamental change.  While the X86 makers are trying to lower the power requirements of their APUs, ARM is busy trying to ramp up the power of their chips.  There are already several vendors establishing a relationship with ARM, up to and including Apple

ARM's Cortex A9 and Mali are impressive, but ARM is already talking about console level graphics quality from their next generation of chips which we will see in roughly 18 months.  This improvement will also encompass their next generation of power efficency research, which should keep power consumption and heat well below what Intel and AMD will be trying to reach.  As well, it might provide an interesting opportunity for NVIDIA as the lack of a license to integrate chips with the new X86 based architecture will not stop them from developing graphics enhancements for ARM based laptops.  Drop by The Inquirer for more on this topic

"CHIP DESIGNER ARM could power over 20 per cent of all laptops shipped in 2015, according to analyst outfit IHS Isuppli.

IHS Isuppli has forecast that the domination of X86 chips in the laptop market will start to diminish as Microsoft releases its Windows 8 operating system. Windows 8 will be the first desktop operating system from Microsoft that will support the ARM architecture that is found in just about every smartphone in existence."
